Does fruit make you fat?
QUESTION: I’ve heard that eating fruit can make you fat. Is that why bodybuilders don’t include fruit in their pre-contest diets?
ANSWER: For starters, fruit does not make you fat. Excess calories make you fat! Fruit is a healthy food, full of nutrients, high in fibre, vitamins, minerals, and low in fat and calories. However, with the advent of the various nutritional approaches to achieve that ripped look, it has become common practice for bodybuilders during pre-contest to omit fruit from their diets. Bodybuilders avoid fruit for two main reasons: 1) they tend to have a high water content and 2) they contain fructose as the main carb (sugar) source. So why does this matter? Muscle only has the necessary enzymes to convert glucose into glycogen, not fructose. The liver however uses fructose exclusively supplying the rest of the body with energy. However, once glycogen stores are full, the enzyme responsible for glucose metabolism, signals the body to convert any remaining fructose into fatty acids and store it as adipose tissue. In essence, fruit sugar is easily converted to fat. This is why bodybuilders attempting to get ripped, try to avoid fruit during the last couple of weeks before a contest.
