Do carbohydrates make you fat?

Fat stores are increased when energy ingestion exceeds usage. Whether that intake comes from protein, carbohydrates or fat is irrelevant. The key to not increasing adipose stores on your body is not ingesting more energy than you’re expending. Once the proper intake level (daily caloric requirements) for your particular objectives is established, macronutrient proportions (how much protein, carbs and fat to ingest) should be set up to allow for maximizing both physical and mental performance at that particular quantity of intake. Since carbohydrates are the body’s preferred fuel source during exercise and the most efficient supplier of glucose, the fuel that the central nervous system runs on, adequate intake is essential for exercisers interested in maximizing both their performance and their health. Since a positive energy balance makes you fat, attempts to prevent such deposition should be focused on keeping expenditure high. This includes maintaining, or better yet, increasing the amount of muscle on your body and being as active as possible (aerobic exercise is the key here). Intake reduction also helps keep intake less than or equal to expenditure, but care should be taken because excessively low or dramatically lowered intake levels can slow the metabolism, both by bringing a wasting of existing muscle and invoking the body’s natural tendency to conserve energy under those circumstances.
