Calories count, but source doesn't matter: study

People trying to lose weight may swear by specific diet plans calling for strict proportions of fat, carbs and protein, but where the calories come from may not matter as much as simply cutting back on them, according to a study.

Researchers whose results were published in the American Journal of Clinical Nutrition found there were no differences in weight loss or the reduction of fat between four diets with different proportions of fat, carbohydrates and protein.

“The major predictor for weight loss was ‘adherence’. Those participants who adhered better, lost more weight than those who did not,” said George Bray, at Pennington Biomedical Research Center in Baton Rouge, Louisiana, who worked on the study.

Earlier research had found that certain diets – in particular, those with very low carbohydrates – worked better than others, Bray told Reuters Health in an email, but there had been no consensus among scientists.

So, I was pleasantly surprised recently when I received three magazines in the mail in one day. Pleasantly because they were free, and surprised because all three were about health, more or less. I thought I would scan quickly through them and into the recycling bin they would go. But I found…
