Governments here and abroad have been cautioning the public for decades on the dangers of high fat diets. One of the problems is that there is consistent inverse association in the percentage of energy coming from fats and sugars. That's no surprise as previous studies such as a two-year dietary study published in the journal Diabetologia showed that food with a lot of fat and few carbohydrates has a better effect on blood sugar levels and blood lipids. Research from the Hebrew University of Jerusalem shows that a carefully scheduled high-fat diet can lead to a reduction in body weight and a unique metabolism in which ingested fats are not stored, but rather used for energy at times when no food is available.
Professor David Lawrence, an expert in nutrition and obesity data analysis, said recently in the journal BMC Medicine that the idea the idea of all calories being equal is flawed and based 'on an outdated understanding of the science'.
Calories from different sources have different effects on the body, with calories from carbohydrates more likely to encourage weight gain.

Not only is the calorie theory under attack, but evidence is also emerging to show that lowering fat might not cut heart-disease risk after all. A major study published in the authoritative New England Journal of Medicine compared the clinical benefits of a conventional low-fat diet with two types of Mediterranean diet, which are naturally considerably higher in fat. The study had to be stopped early because the heart attack and stroke rate in the Mediterranean options was so much lower it was deemed irresponsible to keep patients on the conventional diet.
A study led by Cara Ebbeling, PhD, associate director and David Ludwig, MD, director of the New Balance Foundation Obesity Prevention Center Boston Children's Hospital, found diets that reduce the surge in blood sugar after a meal--either low-glycemic index or very-low carbohydrate-may be preferable to a low-fat diet for those trying to achieve lasting weight loss. Weight re-gain is often attributed to a decline in motivation or adherence to diet and exercise, but biology also plays an important role. The study suggests that a low-glycemic load diet is more effective than conventional approaches at burning calories (and keeping energy expenditure) at a higher rate after weight loss. Faced with mounting evidence, Swedish dietary experts recently made a dramatic U-turn, recommending a low-carb, rather than low-fat, diet for weight loss. The bombshell came from the Council on Health Technology Assessment, which advises the Swedish government. The most important of these hormones, and the one that's crucial for weight loss, is insulin. A low-carb and high-fat diet means less insulin, making it easier to lose weight because less fat is then stored. Dramatic new evidence for this has come from a unique experiment conducted by a personal trainer. Now, according to the conventional wisdom, the weight gain would be the same on both regimens. Sam, who survived childhood cancer (Hodgkin's lymphoma), wondered if his usual low-carb diet was the key, and set about his experiment to find out.


For the low-carb, high-fat part of the experiment, Sam got his 5,000 calories from foods such as eggs, mackerel (which is very fatty), steak, green veg and coconut oil, interspersed with three snacks of nuts - walnuts, pecans or almonds (which are naturally high in fat). While 72 percent of his total calorie intake came from fats, 22 percent came from protein and just 5.9 percent from carbs. With the high-carb diet, most of his calories (63 percent) came from carbohydrates, 13 percent from protein, and 22 percent from fat. He ate garlic bread, low-fat lasagna, crumpets, low-fat yogurts and rice pudding, chocolate muffins and wholewheat bread. Admittedly the types of fat on his high-fat diet weren't your usual fatty foods, such as cream and butter. While Sam's experiment was by no means a scientific one, as well as the weight gain, what was even more striking was what an unhealthy effect the high carbohydrate regimen had on standard markers for heart health.
For when Sam had his blood tested after his three weeks on high carbs, 'the diet effectively gave him metabolic syndrome which is a precursor to heart disease and diabetes. Particularly worrying was that his triglycerides (fats in his blood) had gone up four times, while his so-called 'good' (HDL) cholesterol had dropped. What's more, a level of inflammation in his liver had doubled, which is also linked with diabetes and heart disease. Did the fact that, as a personal trainer, Sam was obviously very fit at the start of his trial make a difference? Research has already shown that if you are eating a high-carb diet, and so have high levels of insulin, you are likely to have more fat in your blood than someone on a high-fat diet. He argues that - as seen with Sam - a high-carb diet tends to lower the good HDL cholesterol that helps keep arteries clear.
At the same time, as glucose from carbs is turned into fat for storage in the body, fatty acids are also produced. Recent research supports the idea that warning about saturated fat in the diet has probably been a mistake. Demonizing fat and encouraging people to eat more carbs can be harmful to people with heart disease, says Dr Malhotra.
Those eating low-carb these days are much more flexible about the amount of fat they get. Western governments have yet to acknowledge the Swedish style U-turn in healthy eating advice.
We are spending billions trying to cope with metabolic diseases such as diabetes, cancer and obesity and the emphasis on low-fat diets is only promoting the metabolic pathways which encourage these diseases. The bottom line is to commit to educating yourself on the healthiest nutritional strategies for your health and not follow any recommendations by government, unless perhaps if you live in Sweden.

Research published in the journal Critical Reviews in Food Science and Nutrition shows why people find it hard to follow government guidelines to cut their fat and sugar intake at the same time -- a phenomenon known as the sugar-fat seesaw. Despite the increased fat intake with a larger portion of saturated fatty acids, their lipoproteins did not get worse. Furthermore, the study found that the low-glycemic index diet had similar metabolic benefits to the very low-carb diet without negative effects of stress and inflammation as seen by participants consuming the very low-carb diet. After weight loss, the rate at which people burn calories (known as energy expenditure) decreases, reflecting slower metabolism.
Based on a review of 16,000 studies, it said the best sorts of food for losing weight were high fat foods which could include anything oils like olive and coconut. A high-carb diet increases the amount of glucose in the bloodstream, which in turn means you produce more insulin. For three weeks he got these calories from a low-fat, high-carb diet; for another three, he ate more fat and cut right back on carbs. I've personally been on many of these public policy and procurement programs investing hundreds of hours of my time trying to convince officials that food pyramids have to be thrown out the window along with many recommended foods they hold praise to. She has consulted on public health policy and procurement in Canada, Australia, Spain, Ireland, England and Germany.
You'll still see this on most food pyramids regulated by government policy on diet and nutrition.
Lower energy expenditure adds to the difficulty of weight maintenance and helps explain why people tend to re-gain lost weight.

When the body is exposed to a high-carb low-fat meal, the pancreas works hard at overshooting the secretion of insulin which then causes the excess to be stored as fat. The fact is, contrary to official advice by our diet dictocrats, high-fat diets lower blood sugar, improve blood lipids, and reduce obesity.
