Hello Guys,

I often though that adding protein and fat to the diet help fat loss because of the way in which they slow the rate in which glucose floods your bloodstream and hence reduces the insulin response. I realize now that this is a little simplistic. My question surrounds the combination of Protein /Fat/Carbohydrates in aiding fat loss. I now know that this is what is referred to as macro ratios. Brand Videos are being used by leading and startup companies to reach to their audience and market themselves. Why does restricting a combination of fats/protein/ or carbohydrates affect a persons ability to lose weight? I have the theory that if you restrict fat or protein or carbs your cortisol levels raise because your body is stressed from not receiving vital nutrients it needs. This then leads to weight gain, especially around the middle. Or, there are certain hormones which kick into affect when eating protein and fats as well as carbs which is vital to burning fat. I know all about carbs but I'm wondering what the scientific reason for this combination is and how is it vital to weight loss?

Thanks
