Jogging or cycling through middle age can delay aging by 12 years

 

Exercise: Cycling can hold back the years

By JENNY HOPE

Taking regular aerobic exercise could stop the biological clock and delay ageing by up to 12 years, claim researchers.

Keeping fit by jogging or cycling through middle age and beyond slows and even reverses the decline in muscle power, balance and co-ordination in later life.

Without regular workouts, maximum aerobic power falls in men by up to half between the ages of 20 and 60.

Women begin to lose fitness aged around 35, with aerobic power also falling by up to half by the age of 60.

 

Eventually, everyday activities become "intolerably fatiguing" for older men and women, says the study published in the British Journal of Sports Medicine.

But cardiovascular training – which strengthens the heart and lungs – would compensate for the onset of middle age, when the body's capacity to use oxygen and generate energy falls with each passing decade.

 And it has the added bonus of prolonging physical independence in old age, according to physical education experts at Toronto University.

They were exploring the idea, first put forward by them 20 years ago, that one of the most important factors influencing the quality of life in old people was the maintenance of sufficient "aerobic power".

Scroll down for more …

The latest study analysed existing research to discover how far the benefits of training last into old age.

It found that relatively high-intensity aerobic exercise over a relatively long period of time could boost maximal aerobic power by 25 per cent.

Dr Roy Shephard, of the university's faculty of physical education and health, said long-term aerobic training can maintain or restore aerobic power in later life.

The effect is the equivalent of turning back the biological clock for older people by up to 12 years, he added.

He said: "A regular exercise programme can slow or reverse the loss of aerobic fitness, reducing the individual's biological age and prolonging independence."

In the UK, most people do not exercise five times a week for 30 minutes or more – the Government's official recommendation for maximum health benefits.

The level of exertion should be enough to raise the heart rate to 120 beats a minute or higher, which includes a brisk walk and swimming.

But taking a stroll or even doing the gardening is also regarded as healthy activity.

A recent survey revealed at least one-quarter of men and women take no moderate or vigorous physical activity.

Other evidence shows regular activity cuts the risk of a range of health problems including diabetes, depression and heart disease. It also reduces the chances of premature death from any illness.

Pensioner on her way to a healthier lifestyle

 

YOU’RE never too old to lose weight – just ask Vida Cotton.

At 72 she’s just lost four stones and is looking forward to a healthy new future.

After years of being frustrated by fad diets the Ayr pensioner was inspired into action when her niece lost stones with weight management experts LighterLife.

She explained: “I have done most diets on the market, but really started to pile on the pounds after having a hip replacement.

“I watched my niece lose four stones with LighterLife and couldn’t wait to start.”

Vida joined the Ayr group and hasn’t looked back since.

She said: “I loved the weekly group meetings, I am delighted with my weight loss and Maureen was absolutely fantastic.”

And it’s not just Vida who’s enjoying her new look.

She added: “My husband keeps on walking into the kitchen and getting a shock as he thinks that there is a stranger in the house, but in fact he has a new model wife.

“My blood pressure is back to normal, my health has improved and I haven’t felt like this in years.”

At 25 Lisa Brown was storing up lots of health problems for the future because of her weight.

She’d struggled to control her eating since she was a teenager and was squeezing into size 18 and 20 outfits.

The Tarbolton girl explained: “I have struggled with my weight since I was 18 when I moved out of home and took charge of what was in the cupboards.

“My partner is in the army and is away lots and I would eat when I was lonely.

“I have tried various ways to lose weight and although I have had some success, I always went back to my old habits and put it all back on.

“I got the wake up call I needed when I went to see the nurse and she told me that in 10 years, if I didn’t do something about my weight, then I could have diabetes and heart problems.”

Lisa took the advice to heart and joined LighterLife and lost a fantastic six stones.

And now she can hardly wait to slip into her slinky bikini when she goes on holiday this year.

She added: “Seven months ago I was buying size 18/20 clothes and am delighted to say that I am actually looking forward to putting on a size 10 bikini when I go on holidays this year.”

Maureen Bradley runs the Ayr club and as a weight management counsellor she it is thrilled to see her clients achieve great results.

She pointed out: “Lisa and Vida have done brilliantly and not only do they both look and feel fantastic, but their health has also improved dramatically.

“LighterLife has been a huge success in Ayr and over the past four years I have helped hundreds of people achieve their weight-loss dreams.”

The Truth About Six Pack Abs – Flawless Facts in Losing Weight

 

A lot of books talking about “abs” are not clear and concise. They are gray areas that need further explanation. They actually contain the same information as is compared to other books. You don’t get to hear much about them because they pieces of junks. The Truth about Six Packs Abs is a lot different from most books. It details a full, comprehensive program in getting the abs that you want. Mike Geary, the author, has an ingenious mind. I am all for his idea of a system assuring of a six pack abs in only a matter of weeks.

Based on my own experience, the first time I had a strong desire to get a six pack abs was when my then girlfriend noticed the beauty of another man’s abs. The idea got me jealous, and even envious of that man. This made me start my quest towards achieving the same abs as that of the other man by working my way through the internet in search of Ab training practices. As has been mentioned, I got acquainted with some crappy and ineffective programs. Fortunately, after six months, my friend suggested a book entitled “The Truth about Six Pack Abs”. After getting the book, I progressed towards achieving the perfectly-chiseled abs.

Would you like to know the reality about “The Truth about Six Pack Abs”?

Actually, it really works! The testimonials of previous users would attest to its effectiveness. In my opinion, the success stories were told not only because of the uniqueness and the effectiveness of the method, but also because of the author’s ingenuity.

Ten Surprising Nutrition Facts

 

The American diet circa 2007 is a disaster – but positive change has begun. Those were the twin themes of the "Fourth Annual Nutrition and Health Conference" held in San Diego, Calif., May 14-16, 2007. The conference was sponsored by the University of Arizona’s College of Medicine in conjunction with the Program in Integrative Medicine (PIM); PIM was founded and is co-directed by Dr. Weil. 

The three-day event brought together leading nutrition researchers from around the world, bearing plenty of both bad and good news. Some highlights:

 

Bad News:

4. Vitamin D deficiency is widespread. The following health problems have been linked to vitamin D deficiency: type 1 and 2 diabetes; multiple sclerosis; rheumatoid arthritis, osteoarthritis, periodontal disease, increased susceptibility to infection; osteoporosis, low birth weight infants; low seizure threshold; cancers of the breast, prostate, colon, pancreas and ovary; non-Hodgkin’s lymphoma; hypertension, myocardial infarction, stroke, congestive heart failure; wheezing in childhood, and compromised muscle strength and falls in the elderly.

   From the presentation, "Vitamin D Deficiency: The Cause of Everything?" by Louise Gagne, M.D., Clinical Assistant Professor, Dept. of Community Health and Epidemiology, University of Saskatchewan, Saskatoon, Canada.

5. In real dollars, the price of fresh fruits and vegetables has risen nearly 40 percent since 1985. In real dollars, the price of soft drinks has dropped 23 percent. The reason unhealthy foods tend to be less expensive on average than foods such as fresh fruits and vegetables has much to do with American farm policy.

Why fast foods are bad, even in moderation

 

Eating a diet consisting largely of fast food could cause your waistline to bulge more than eating the same amount of fat from healthier sources.

Monkeys fed a diet rich in trans-fats – commonly found in fast foods – grew bigger bellies than those fed a diet rich in unsaturated fats, but containing the same overall number of calories. They also developed signs of insulin resistance, which is an early indicator of diabetes.

Trans-fats, or partially hydrogenated oils, are found in many fast foods and also in baked goods and processed snacks. They dramatically increase the risk of heart disease – even more than saturated fats found in animal products.

Kylie Kavanagh, at Wake Forest University Baptist Medical Center in Winston-Salem, North Carolina, US, wondered how this "killer fat" would affect the risk of diabetes in 51 vervet monkeys.

She fed one group of monkeys a diet where 8% of their daily calories came from trans-fats and another 27% came from other fats. This is comparable to people who eat a lot of fried food, says Kavanagh. A different group of monkeys was fed the same diet, but the trans-fats were substituted for mono-unsaturated fats, found in olive oil, for example.

Both groups ate the same total calories, which were carefully metered to be just enough for subsistence.

Path to diabetes

After six years on the diet, the trans-fat-fed monkeys had gained 7.2% of their body weight, compared to just 1.8% in the unsaturated group. CT scans also revealed that the trans-fat monkeys carried 30% more abdominal fat, which is risk factor for diabetes and heart disease.

"We were shocked. Despite all our enormous efforts to make sure they didn’t gain weight, they still did. And most of that weight ended up on their tummies," says Kavanagh, who presented her findings at the American Diabetes Association meeting in Washington DC, on Monday. "This is walking them straight down the path to diabetes."

This is the first study to show such a dramatic result on abdominal fat, adds Dariush Mozaffarian at the Harvard School of Public Health in Boston, US. "The days of thinking about fats just as calories are over," he says.

Partially hydrogenated oils can easily be replaced by other oils during food production. Last week, fast-food giant Wendy’s announced that it was cutting partially hydrogenated oils from its food in the US and Canada, while in January, food manufacturers in US were ordered to label all trans-fats on packaged goods.

‘Superfoods’ Everyone Needs to Stay Alive and Healthy

 

Experts say dozens of easy-to-find ‘superfoods’ can help ward off heart disease, cancer, cholesterol, and more.

Imagine a superfood — not a drug — powerful enough to help you lower your cholesterol, reduce your risk of heart disease and cancer, and, for an added bonus, put you in a better mood. Did we mention that there are no side effects? You’d surely stock up on a lifetime supply. Guess what? These life-altering superfoods are available right now in your local supermarket.

"The effect that diet can have on how you feel today and in the future is astounding," says nutritionist Elizabeth Somer, author of Nutrition for aHealthy Pregnancy, Food & Mood, and The Essential Guide to Vitamins and Minerals.

"Even people who are healthy can make a few tweaks and the impact will be amazing," Somer says. "I’d say that 50% to 70% of suffering could be eliminated by what people eat and how they move: heart disease, diabetes, cancer, hypertension can all be impacted."

You don’t need specific foods for specific ailments. A healthy diet incorporating a variety of the following superfoods will help you maintain your weight, fight disease, and live longer. One thing they all have in common: "Every superfood is going to be a ‘real’ (unprocessed) food," Somer points out. "You don’t find fortified potato chips in the superfood category."

Top Superfoods Offering Super Health Protection

 

• Beans
• Blueberries
• Broccoli
• Oats
• Oranges
• Pumpkin
• Salmon
• Soy
• Spinach
• Tea (green or black)
• Tomatoes
• Turkey
• Walnuts
• Yogurt

Blueberries — Antioxidant Superfood

Packed with antioxidants and phytoflavinoids, these berries are also high in potassium and vitamin C, making them the top choice of doctors and nutritionists. Not only can they lower your risk of heart disease and cancer, they are also anti-inflammatory.

"Inflammation is a key driver of all chronic diseases, so blueberries have a host of benefits," says Ann Kulze, MD, of Charleston, S.C., author of Dr. Ann’s 10-Step Diet, A Simple Plan for Permanent Weight Loss & Lifelong Vitality. When selecting berries, note that the darker they are, the more anti-oxidants they have. "I tell everyone to have a serving (about 1/2 cup) every day," Dr. Kulze says. "Frozen are just as good as fresh." Be sure to include lots of other fruits and vegetables in your diet as well. Remember too that, in general, the more color they have, the more antioxidants.

Omega 3-Rich Fish — Superfoods for the Heart, Joints, and Memory

"We know that the omega 3s you get in fish lower heart disease risk, help arthritis, and may possibly help with memory loss and Alzheimer’s," Somer says. "There is some evidence to show that it reduces depression as well."

Omega-3s are most prevalent in fatty, cold-water fish: Look for wild (not farmed) salmon, herring, sardines, and mackerel. Aim for two-to-three servings a week. Other forms of omega 3s are available in fortified eggs, flax seed, and walnuts. These superfoods have the added benefit of being high in monounsaturated fats, which can lower cholesterol.

Soy — Superfood to Lower Cholesterol

A study reported in The Journal of the American Medical Association (2003) showed that a diet of soy fiber, protein from oats and barley, almonds, and margarine from plant sterols lowered cholesterol as much as statins, the most widely prescribed cholesterol medicine. "Look for tofu, soy milk, or edamame — not soy powder," says Somer. In other words, soy sauce won’t do the trick. One caveat: If you have a family history of breast cancer it is not recommended that you eat extra soy.

Fiber — Superfood Aids Weight Loss and Checks Cholesterol

A diet high in fiber will help you maintain healthy cholesterol and blood sugar levels. As a bonus, because fiber helps you feel full longer, it’s a great tool in weight management. Whole grains, beans, fruit, and vegetables are all good sources. Try throwing some beans in your salad, recommends Kulze. "Fresh, frozen, or dried are the best. You can use canned, but they tend to be higher in sodium," Kulze warns.

Tea — Superfood for Lowering Cholesterol and Inhibiting Cancer

"The overall antioxidant power of black tea is the same as green tea," says Kulze, "but green tea does have ECGC, a powerful antioxidant that we really do think is quite special." A recent Japanese study on green tea found that men who drank green tea regularly had lower cholesterol than those who didn’t. Researchers in Spain and the United Kingdom have also shown that ECGC can inhibit the growth of cancer cells. For a double health whammy, replace sugary sodas with tea.

Calcium

OK, OK, you know the drill: Calcium helps build strong bones and prevents osteoporosis. Look for it in dairy products or supplements. Added bonus: Some studies show that calcium helps with weight loss. Here are the calcium levels recommended for adults by the USDA:

• Age 9 to 18 — 1,300 mg
• Age 19 to 50 — 1,000 mg
• Age 51 and over — 1,200 mg

And Finally, the Yummiest Superfood Yet … Dark Chocolate

New research has shown that dark chocolate is packed with antioxidants and can lower blood pressure. Kulze recommends that you look for chocolate with 60% or higher cocoa content; the darker, the better. In addition, the darker it is, the lower the fat and sugar content. Now that’s our kind of health food!

 

South Beach Diet

 

Definition

The South Beach diet is a three-phase, carbohydrate-restrictive diet. It emphasizes foods that are low on the glycemic index (GI) and low in saturated fat, such as lean meats, vegetables, cheeses, nuts, and eggs. Unlike other carbohydrate-restrictive diets, such as the Atkins and Zone diets, the South Beach diet promotes "good" carbohydrates, such as whole grains and fruit.

Origins

The creator of the South Beach diet, Dr. Arthur Agatston, is considered a leading cardiologist and is the director of the Mount Sinai Cardiac Prevention Center in Miami Beach. Originally, he had intended to design an eating plan to improve the cholesterol and insulin levels of his patients. However, Dr. Agatston soon discovered that his patients also lost weight on his plan. After further research, he approached Marie Almon, R.D., chief clinical dietician at the hospital, to help develop the eating plan into an effective diet. The results became the South Beach diet. Having sold more than a million copies since its publication in April 2003, The South Beach Diet book has remained on the New York Times bestseller list for over a year.

Benefits

The primary benefit of the South Beach diet is considered by many to be its initial rapid and significant weight loss—8–13 lb (4–6 kg) in the first two weeks. After the first two weeks, weight loss continues at a slower rate, averaging 1–2 lb (0.4–1 kg) weekly. In addition to weight loss, the diet reduces cholesterol and insulin levels, thus reducing the risks of diabetes and heart disease. It is claimed that the diet is easy to follow because it is designed to eliminate cravings and has more flexible food options after the first two weeks.

Description

In his book, The South Beach Diet, Dr. Agatston states that "this diet is not low-carb. Nor is it low-fat." Instead, the diet focuses on eating the "good" carbohydrates (fruits, vegetables, and whole grains) and "good" fats (olive oil and nuts) rather than eliminating them from the diet entirely.

Dr. Agatston based the core of his dietary plan around the glycemic index –the increase in blood sugar levels by foods containing carbohydrates during a set amount of time.

After consumption, food is metabolized into sugars and promotes the release of the hormone insulin. When the blood contains excess sugar, insulin removes it from the blood stream by storing it in cells, including fat cells. High-glycemic carbohydrates (greater than 70 GI) are metabolized rapidly, which causes elevated insulin production. High levels of insulin result in more blood sugar being stored as fat, thus causing weight gain. This pattern induces craving for more carbohydrates, thus leading to the consumption of more high-GI foods. Low to moderate-GI foods, however, raise insulin levels more slowly and sugars are metabolized more effectively, thus reducing the amount of blood sugar stored as fat. Cravings for more food is reduced. In addition, by eating these low-GI foods, the risk of insulin resistance that can lead to atherosclerosis and diabetes is reduced. As such, Dr. Agatston designed the South Beach diet to promote foods low on the GI and eliminate the body’s craving for high-GI foods.

The South Beach diet consists of three phases. Phase one is the strictest part of the diet and lasts for two weeks. The purpose of Phase one is to banish the dieter’s cravings for high-GI foods such as bread, rice, potatoes, pasta, and sugar. Alcohol, fruits, cereal, and such vegetables as carrots and corn are also restricted during Phase one. Instead, protein-rich foods are emphasized, such as lean meat, fish, eggs, cheese, nuts, and vegetables. Coffee and tea are also allowed. Three regular-sized meals are eaten each day, supplemented by mid-morning and mid-afternoon snacks as well as dessert. During this period, the body chemistry will change dramatically until cravings for high-GI foods are eliminated and insulin resistance is improved/lowered. In addition, rapid weight loss is typically experienced.

Phase two reintroduces several of the restricted foods and encourages eating from all the dietary food groups, the expected result being that the body will neither crave high-GI foods nor store food as excess fat to the same degree. Such high-fiber carbohydrates as whole-wheat pasta and bread and most fruits are now permitted. Moderation remains the key to success for this phase and low-GI foods are strongly encouraged. Phase two continues until the dieter reaches his or her ideal weight, ideally averaging a loss of one to two pounds per week.

Phase three, the ultimate goal, focuses solely on weight maintenance. Having reached the ideal weight, the dieter now makes the changed eating habits a lifestyle from this point forward. Basic dietary techniques are still maintained. Only the high-GI foods and "bad" fats from the previous two phases continue to be restricted. Altered body chemistry will promote long-term cardiovascular health and reduce the risk of diabetes. Should weight gain occur, Phase one of South Beach diet is reintroduced until the weight goal is achieved.

Preparations

There are no initial preparations required for the South Beach diet. However, as with most diets, it is wise to consult with a physician beforehand. Blood testing for insulin, glucose, and cholesterol levels is suggested. It is strongly recommended that dieters taking medications for medical conditions such as heart disease consult a physician before going on the South Beach diet. Similarly, diabetics on insulin or other medications are advised to have a doctor monitor their blood sugar regularly and determine if they are at risk of kidney impairment while on the diet. It is also recommended that a registered dietitian be consulted to determine the dietary needs of certain medical conditions, such as pregnancy.

Precautions

The South Beach diet is not recommended for people suffering from or at risk of kidney problems. The diet’s high protein content can place increased strain on the kidneys, possibly causing long-term damage as well as kidney stones and bone loss. Additionally, the possibility of ketosis-induced dehydration during Phase one can increase the risk of further kidney impairment. Dehydration occurs when the body experiences water loss with accompanying loss of important blood salts like potassium and sodium. Ketosis occurs when carbohydrates are not available and the body burns an excessive amount of fat, during which some ketones, or fat fragments, are excreted. The restrictive nature of Phase one may also induce mineral and vitamin deficiencies. Remaining in Phase one of the diet for longer than two weeks greatly increases the risk of losing bone and muscle mass. Dieters should remain in Phase one for no longer than three or four weeks.

Some nutrition professionals contend that the South Beach diet menus provided in the book lack important nutritional information and detailed portion sizes as well as specific substitutes for foods the dieter cannot or will not eat. They claim that these aspects, combined with the restrictive nature of the diet, can make sticking with the South Beach diet on a long-term basis difficult for some people. Also, they assert that the diet does not emphasize an exercise regimen and that exercise is vitally important to avoid the loss of muscle and bone mass, especially during Phase one of the diet.

Side Effects

Despite Dr. Agatston’s claims to the contrary, the South Beach diet is both a low carbohydrate and a low fat diet. For this reason, one main concern regarding the diet is the risk of ketosis, especially during Phase one. Ketosis can cause such symptoms as dehydration, dizziness, heart palpitations, fatigue, lightheadedness, and irritability. Hypoglycemia, low blood sugar, headaches, and excessive fluid loss are also commonly associated with this diet. Cramping and tired muscles can be incited by salt depletion. Kidney functions can be impaired, possibly leading to serious health issues. Kidney function can be further impaired by the diet’s high protein requirements. These side effects typically lessen or fade at the beginning of Phase two, when a more balanced diet is undertaken.

Research & General Acceptance

Unlike the majority of low-carbohydrate diets, the medical community generally accepts the South Beach diet. The South Beach diet contains all the major food groups, promotes ingestion of "good" fats for maintaining heart health, and is flexible enough to accommodate most dietary needs.

However, many clinicians and dietitians agree that the rapid initial weight loss results mostly from water loss. Much of this weight can return once the dieter rehydrates.

Another important criticism by medical and nutritional professionals is the lack of evidence to support Dr. Agatston’s claims connecting the consumption of low-GI foods and weight loss. They assert that as of the early 2000s, there is no scientific proof that eating low-GI foods will have any more weight loss effect than eating a normal, calorie-reduced diet that includes carbohydrates; that Dr. Agatston also fails to take into account the interaction of different foods when eaten together, which can dramatically alter glucose metabolism; and that this failure means that utilizing the Glycemic Index as a gauge for what foods to eat is not only confusing but also slightly misleading.

Can I lose belly fat or have a flat belly by starving and not exercising?

 

No, you cannot get a flat stomach by starving yourself. Semi-fasting long term can mess up your metabolism and cause all sorts of health issues. The longer you go, the more problems, sometimes not reversible, will occur. Your belly is likely to balloon out in the final stages of starvation and the internal organs start to shut down.

A well balance diet and sensible exercise will do it. However, you must remember, you did not gain that weight in a day, or a week or even a month. It can take as long to lose it as it did to gain it. Think long-term health, not short term looks.

Instead of starving yourself start eating healthier. Eat smaller meals, eat more meals a day, eat more vegetables and fruit, drink more water, less sugars and empty calories (less soft drinks, cakes, cookies). Switch to whole-wheat versions of your bread and pasta, brown rice instead of white rice.

Losing or maintaining an ideal weight is not a difficult task if you follow a healthy lifestyle including low GI eating, regular aerobic exercise and suitable supplements. Whatever you do, do not starve yourself. Talk to a doctor or a family member. You need to lose body fat if your BMI is over 25. Excess body fat, or obesity, will affect not only your appearance but also your health and can lead to heart disease, diabetes, and more.

Nutrition is important. In the pursuit of a flatter stomach, many people diet or starve themselves. Little do they know that by starving themselves, they are slowing down their metabolism and forcing their body to go into starvation mode as a defence mechanism.

Body Fat Explained

What Is The Purpose Of Storing Body Fat?

Storage of fat on the body is a critical defence mechanism. Remember, the human body has not changed essentially since the Stone Age. At that time starvation and famine were ever-present dangers to survival, while over-consumption and obesity were unheard of. To enable Stone Age humans to survive periods of food scarcity, the human body was designed to store energy which could then be drawn upon in times of famine. Thus for example, people could overeat during the hunting season, or when food was plentiful, and the surplus would be stored as fat tissue (adipose tissue). And when food was short, the body would burn the deposite fat as energy. Of course Stone Age life and body chemistry was/is much more complicated than this simple explanation suggests, but it suffices to explain why we have a built-in fat storage facility.

How Are Carbs, Protein And Fat Absorbed And Stored?

The human body needs energy to power muscles and to fuel the millions of chemical and biological reactions which take place throughout our system every day. This energy comes from the food we consume in our diet. Food consists mainly of water and three types of nutrient – protein, dietary fats and carbohydrate – which are found in varying proportions in most foods. These nutrients are broken down, digested and absorbed by the body in the gastrointestinal tract, running from the mouth to the anus. Each of these macronutrients is processed and absorbed by the digestive system in different ways.

How Are Surplus Carbs Used And Stored?

Carbohydrate is the major source of energy for the body. This is because, of all nutrients, it converts most readily to glucose which is the body’s preferred fuel. When we eat carbohydrate, it is converted to glucose in the digestive tract and distributed via the liver to cells throughout the body for use as energy. Once our immediate energy needs are satisfied, the remaining carb glucose is handled in one of two ways. Either it is converted to liquid glycogen (a temporary source of readily available energy) and stored in the liver or muscles. Or, it is converted into fatty acids by the liver and stored in adipose cells (fat-cells) around the body.

How Is Surplus Protein Used And Stored?

Protein is broken down into amino acids in the stomach and small intestine, then distributed via the liver to cells throughout the body for a variety of uses included cell formation and repair. Some surplus protein amino acids are kept circulating in the bloodstream, the remainder is either converted into a type of simple sugar and used as energy, or (like carbohydrate) is converted to fatty acid and stored in adipose cells.

How Is Surplus Dietary Fat Used And Stored?

Dietary fat is broken down into fatty acids and glycerol by the stomach and small intestine. It is then distributed (in the form of triglycerides) via the lymphatic system and bloodstream to the cells for a variety of specialized uses or, in the absence of sufficient carbs, for energy. However, since dietary fat cannot be converted into protein and only about 5 percent (the glycerol part) is convertible into glucose, and because dietary fat is not the body’s preferred choice of fuel, a significant amount ends up being stored as body fat in the adipose tissue.

Conversion Of Body Fat To Energy

If energy is required suddenly, the body first uses up its glycogen reserves. After this, it converts the body fat in the adipose cells into energy by a catabolic process called lipolysis. During lipolysis, triglycerides within the adipose cells are acted upon by a complex enzyme called hormone sensitive lipase (HSL). This converts the triglyceride into fatty acids and glycerol. The fatty acids are then transported via the bloodstream to tissues for use as energy, or (along with the glycerol) taken to the liver for further processing.

Adipose Tissue

Adipose cells which make up adipose tissue are specialized cells which contain and can synthesize globules of fat. This fat either comes from the dietary fat we eat or is made by the body from surplus carbohydrate or protein in our diet. Adipose tissue is mainly located just under the skin, although adipose deposits are also found between the muscles, in the abdomen, and around the heart and other organs. The location of fat deposits is largely determined by genetic inheritance. Thus it is not possible to affect where we store fat. Nor is it possible to influence from which area the body burns fat for energy purposes.

Why Do We Get Fat?

Most of us develop body fat because we eat more calories than we burn in exercise. Given a culture which emphasises "value for money food portions" and "super-sizing", along with an steady increase in serving size, an upsurge of new tasty high-calorie foods and energy drinks, such over-consumption is perhaps only to be expected. Lack of exercise is also a major contributory factor. However, overeating and lack of fitness is not the whole story.

Why Are So Many People Obese?

The prevalence and incidence of obesity (the disease of excess body fat) has risen considerably over the past 25 years, both in the developed and undeveloped world. Why is this? We don’t know for sure. Despite extensive research into the causes and predictors of obesity, they remain unquantified. In other words, although we know that (eg) excessive calorie intake, lack of exercise, metabolic disorders and genetic inheritance all impact on the incidence and symptoms of obesity, experts still don’t know the relative contribution of these causal factors. The only thing that most experts agree on, is that the recent upsurge in obesity cannot be attributed in any major way to the influence of genes, since genetic changes typically take millennia to appear, not two decades. Even so, the connections between type 2 diabetes, raised blood fats, obesity and insulin insensitivity – a cluster of symptoms which form the condition known as insulin resistance syndrome – is evidence of a progressive deterioration in the body’s metabolic efficiency, which may be a growing underlying factor in the development of excess body fat among many people.
