It's true that following a low-carb diet is the best way to avoid obesity and heart disease. But some people make the mistake that carbohydrates is a "bad" nutrient. The fact is that carbohydrates are a very important nutrient for active men, especially those building muscles. If you are an active man, the following tips will help you get the most out of your nutrition regimen.

#1 - Choosing your carbohydrates is key. When working out, your body burns a combination of carbohydrates from the muscles and stored fat. Not taking in enough carbohydrates in a muscle-building regimen might result in muscle loss in worst cases! For best results, look for whole-grain sources, whole-wheat bread, and brown rice. Avoid the refined (white) varieties.

#2 - Protein is also a very important nutrient, but you already know this, don't you? It helps rebuild muscles after a workout, and is a great source of sustained energy throughout the day. Eggs, fish, soy, and lean meat are all great sources of "workout" protein.

#3 - Drink up! Drinking enough water before, during, and after a workout will keep you going. It's also important to fuel up around 2-4 hours before a workout with lots of good carbs, enough protein, and just a little fat.

#4 - Take muscle-building supplements. There are a lot of products to choose from out there, but Acai berry should be part of your supplement regimen. It's not only a fat-burning supplement -- it also has good amounts of protein and antioxidants (which minimizes the free radical damage that heavy breathing causes) that help your body build muscle at its optimum rate.
