good diets to steadily build muscle?

Eat the foods that bodybuilders eat in the same fashion that they eat them (5-6 balanced and proportioned meals, eat every 3 hours). At least 70% of your muscle gains will be due to the food you eat, so that is the most important aspect to focus on. There's to many foods to list here, so just do a search on the foods bodybuilders eat. They have it down to a science on which foods sets your body in the most anabolic (muscle building) and fat burning mode. Right down to getting the maximum release of good hormones (testosterone and growth hormone) and the minimum of bad hormones.
