Resistance training gets your muscle's attention, it still needs several things to
fulfill its vow to rebuild bigger and stronger than ever. Among them is proper
nutrition. Just what constitutes proper nutrition for muscle building is another
controversial area - witness the endless products that suggest they can help you
pack on muscular pounds.
  While most expert remain skeptical of such claims for all but a few products,
there seems to be general agreements that your intake of protein and total
calories should increase if you want to add lean body mass. "the bottom line is
this: if you're not consuming enough energy, then you are going to be in trouble
either maintaining or building muscle","So priority number 1 has to be energy".
Even for those of us who were born without that all-important math gene, the
equation is simple. If you don't eat enough to replace the calories that your body
is burning off when you're weight training, you'll actually lose weight and muscle
mass. But figuring out how much to eat is a little trickier."In some studies of very
good weight their energy intake was approximately double but if you're not
training quite as hard, you obviously won't need as much generally eating about
40 calories per kilogram of body weight when trying to build muscle. That means
that the average 170lb pound man might need to eat roughly 3100 calories a
day. A 230lb pound man should consume 4200 calories a day or more.

  You'll need to make sure that you're eating between 1.4 and 1.8 grams of
protein for every kilogram of body weight. That translates into about 123 grams
of protein for a 170lb pound man and about 167 grams for a 230lb pound man. (
just to give you an idea, three ounces of tuna packs 25.1 grams of protein, a
three ounce chicken breast has 26.7 grams, and an eight- ounce glass of 2%
low-fat milk contains 8.1 grams.
