So what actually makes you fat? Is it high carb diets or high fat diets? Let’s look at what the science says.
Can glucose actually be be converted into fat? Yes. It’s a process called Lipogenesis that occurs in the liver and adipose tissue. However, this only happens at a fractional level.
In fact, a recent study examined overfeeding women by 50% above their maintenance calories. Through sophisticated methods they were able to show exactly where the stored body fat came from: carbs or fats.
What did they find? Participants, on average, stored a total of 282 grams of fat per day in adipose. A measly 4 grams of that fat resulted from Lipogenesis, and 278 grams came from dietary fat. So carbs only contributed to 1.4% of fat gain during overfeeding in this study.
So if carbs aren’t being stored as fats, we must be getting fat from fats right? Not so fast. The intake of one directly affects the metabolism of the other.
For fat storage, as carb intake goes up and fat intake goes down, you store less fat into adipose. As fat intake goes up and carbohydrate intake goes down, you store more fat into adipose.
What does all this mean? It means the body is extremely flexible in the fuels it can use, and it will base its preference on what it’s exposed to. Some might find it reasonable to suggest that a low-fat diet is probably better than a low-carb diet from a physiological perspective, because you store less total fat. In reality, however, it’s not the rates of fat oxidation, carb oxidation, or fat storage that tell the tale of obesity. It’s the rate of fat oxidation versus the rate of fat storage, and this is determined by overall energy balance or calories in versus calories out. #fitness #fitfam #workout #gym #bodybuilding #progress #fitnessaddict #dedication #weightloss #strong #motivation #rochester #fitnessmodel #lift #hardwork #success #personaltrainer #science #fitspo #inspire
