The wrong food fight

Posted by Colin Rose on February 11, 2009

Very well written. But the biggest nutritional problem is not finding cheap brown rice but obesity, too many calories from all sources, resulting in many disastrous consequences, like Type 2 diabetes. If the population cut calorie intake by an average of 20% we could save $billions in food, waste disposal and medical costs. And the best way to do that is to ditch the junk food. However, I note that Becel margarine is a “founding sponsor” of the HSF. If there is any food junkier than margarine I would like to know. So the HSF can’t risk condemning junk food and losing it’s main sponsor.

We feel awkward questioningthe judgment of the Heart and Stroke Foundation (HSF) when it comes to cardiac health issues, but their new and much-trumpeted report about the supposed costs of healthy eating seems deranged. The foundation blasts grocers…read more…

Michael Phelps’ atherogenic diet

Posted by Colin Rose on August 16, 2008

A gold medal diet?

If Michael Phelps’s diet is really as reported and he continues to eat like this, his risk of atherosclerosis and probably some cancers are elevated. While no detailed nutrient breakdowns are available, one can infer that a large fraction of his calories are coming from saturated fat and refined carbohydrate, nutrient poor calories. The “energy drinks” are liquid candy. He consumes few vegetables and no fruit. His intake is low in fiber, and could be low or borderline in other nutrients. While such a diet may rapidly supply the calories he needs for Olympic gold medals, in the long run his health will suffer. If he thinks he can eat chocolate chip pancakes as long as he exercises enough, he is dead wrong. And what kind of example does he set for the children of the USA and the world? “Hey Mom, I can eat chocolate chip pancakes instead of broccoli, just like Michael Phelps.”

DIRECT. More obese liars.

Posted by Colin Rose on July 16, 2008

We have already commented on a similar diet study, A to Z. Again with DIRECT (DIetary RandomizEd Controlled Trial) we have another attempt to prove the Atkins diet is better but is really another demonstration of lying by most overweight and obese people. Any study on diet and energy balance that cannot first demonstrate that the First Law of Thermodynamics is obeyed from self-reported data is totally unreliable and unreproducible and should never be published.

While the data as presented are hard to interpret in terms of detailed energy balance because daily energy intake and expenditure is not reported, as it should have been, the subjects claimed to be doing more exercise and eating less but only lost 10 pounds in two years. The prescribed diets contained 1800kcal for men and 1500kcal for women. These values are close to the basal metabolic rates of these mostly obese people. They should have lost weight continuously and markedly during the trial. Let’s see how much they should have lost if they were reporting accurately. They claimed to be eating about 500 kcal less than baseline per day on all diets. Even doing the same amount of exercise they should have lost about a pound per week (one pound of fat is about 3500 kcal) or about 50 pounds per year or 100 pounds in 2 years. Since they claimed to be doing more exercise they should have lost even more. If they had been telling the truth, most participants should have starved to death well before the end of the study! Ergo, most overweight and obese people lie about food intake and exercise; they tell investigators what the investigators want to hear.

Obesity is and always has been caused by junk food addiction. Until we deal with that, the pandemic of obesity and its terrible consequences will only worsen. Unlike most infectious diseases, there is no vaccine against  addictions. We all must make the right choices as to what we put into our bodies. In developed capitalist democracies resisting the self-destructive temptation to consume all manner of cheap addictive substances or to adopt addictive behaviours readily supplied by highly profitable enterprises is the hardest task we have. And how to deal with it is not taught in medical school.

————————————————————————-

That obese people lie about food intake was proven beyond doubt by a study using doubly-labeled water to measure true energy expenditure. About 65% of these subjects were overweight or obese. They claimed to be eating only about 1500 kcal/day, about 40% less than they actually ate, but were burning 2500. So, they should have had a deficit of 1000 kcal/day and be losing weight dramatically but their weights were stable. Ergo they were “misreporting”, a euphemism for lying.
