There’s a belief in the Low Carb community that fat doesn’t make you fat. And to some extent there’s some truth in that. Most people are fat not because of the fat in their diet but because of the carbs in their diet. Here’s a typical infographic used by the Low Carb community which illustrates the point.
Some people, myself included, have done experiments where we ate thousands of calories of fat for days or weeks and have seen little to no weight gain. However, there’s often not much data on the diet selected or timing windows. Did these people eat in a time restricted window?
Keto Savage n=1
Keto Savage did a two month challenge where he ate 4,000 calories of the keto diet. That was 350g of fat a day. He went from 4.3% body fat to 10.1% body fat in those two months.
He best part is that he logged his food and made videos as he went along. It is important to note that he did this “experiment” after he was on a weight cut for a bodybuilding show so he would have been at a reduced body fat level to begin with.
So, yes. Fat can make you fat – even on a Low Carb diet. It takes a lot of work, but it can.
