Carbs Making You Sick?

Bodybuilders need carbs – and lots of them – to get the energy needed to get big and strong. But that’s not all: Bodybuilders also need carbs to protect muscle tissue and protein from breaking down. Carbs not only supply energy but also are anti-catabolic.

But not all carbs are created equal. In fact, some might cost you muscle.

A study looked at the impact of carbohydrates on the cardiovascular system of young, lean, healthy test subjects. The subjects were given three meals in a random order, with each meal providing 50 grams of glucose, bread or pasta. Blood samples were then taken and analyzed zero, one, two, three and four hours after each carbohydrate-rich meal.

Researchers found that mega-increases in blood glucose “aggravate inflammatory processes in lean, young adults. This mechanism may help to explain relations between carbohydrates, glycemic index and the risk of chronic disease.”

So here’s your FUSION FACTOID: While it’s common to chug a high-glycemic-index carb drink following a tough workout, be sure to be precise. Take in only the exact amount of simple carbs you need to replenish glycogen stores and trigger the optimal insulin response. And avoid ingesting simple carbs at all other times of the day as much as possible. Not only will they make you fat, but they can make you sick as well and ultimately kill your muscle growth.
