Hi
@Guzzler,
Countless controlled studies have been conducted on this subject and they come out with same conclusion:
Aka, if your body burns 1000 calories per day, then if you eat 1000 calories per day, you will not gain weight. And it doesn't matter if those 1000 calories are composed of high fat, low fat, high carb or low carb kind of diet. The interesting part is that in same body situation, if you then start to eat e.g. 1500 calories per day, you will gain exactly the same weight over the same period of time. Again no matter how those 1500 calories are composed. No matter if it is a high fat, low fat, high carb or low carb kind of diet.
If you are into the scientific and fact based details then suggest you read some of the
controlled studies around what happens when you switch to a low carb diet, as it always causes an initial (relatively) sharp decrease in total weight due to the drop in water weight that accompanies carb restriction. That is because the glycogen stored in our liver, muscles, and fat cells are stored in a hydrated form, with three to four parts water. Example of such study:
