Generelt: Undersøgelser for at spise low-fat, low-carbohydrate eller low-glycemic http://jama.jamanetwork.com/article.aspx?articleid=1199154#RESULTS
(The low-fat diet produced changes in energy expenditure and serum leptin42- 44
that would predict weight regain. In addition, this conventionally recommended diet had unfavorable effects on most of the metabolic syndrome components studied herein. In contrast, the very low-carbohydrate diet had the most beneficial effects on energy expenditure and several metabolic syndrome components, but this restrictive regimen may increase cortisol excretion and CRP
. The low–glycemic index diet appears to have qualitatively similar, although smaller, metabolic benefits to the very low-carbohydrate diet, possibly without the deleterious effects on physiological stress and chronic inflammation
. These findings suggest that a strategy to reduce glycemic load rather than dietary fat may be advantageous for weight-loss maintenance and cardiovascular disease prevention.)
Now let’s look at the effect of changing the composition of the meal. What happens if you change the ratio of fat, protein, and carbohydrates, but not the amount of calories you eat?
Recent studies have clearly shown that low-fat diets don’t work. End of story. What about low-carb diets?
These do work IF
you give up carbs — the most important source of health-giving compounds in our diet, including fiber, vitamins , minerals, antioxidants, phytonutrients, and more. So weight loss from a low-carb diet comes at high price: poor health
Low-carb diets also give you constipation, bad breath, hemorrhoids, headaches, and even muscle weakness and pain.
That leaves the question of protein. What happens when you increase the amount of protein in your diet?
Before I go on, let me clarify that when I am talking about increasing protein I mean nuts, seeds, beans, whole grains, omega-3 eggs, wild fish, and lean poultry or other meats. I am by NO
means talking about a steak and cheese diet
