I am currently trying to cut, and am using a particular diet that has ended up giving me some muscle even though I have lost a noticable amount of fat.
I weighed 215 for starters. I set 2500 calories to loose 1 1/2 to two pounds a week and set as guidelines to average NO MORE than 200 grams of carbs and NO LESS than 200 grams of protein a day AVERAGE over the course of a week. Basically 3 protein based meals, workout, Surge, protein based meal, protein based meal, and perhaps 1 more protein based meal if I go to bed late. Each meal about 350-400 cals and 35-40% protein (something like 2 cups 2% milk and 2 Low-Carb Grow!, or 1 1/2 cup cottage cheese and 1/2 piece of fruit, or 1/2 pound lean meat or fish and a big bowl of veggies).
Low-Carb Grow! first thing in the morning and last thing before bed, 90 minutes before workout and 90 minutes after workout (or another meal option like I described).
THEN, considering your age and relative leanness gradually add in a small amount more carbs like an extra packet of oatmeal to a meal (except the last one before bed) or use regular Grow! Continue adding this to another meal a day each week as long as you seem to be on track, cut out from one meal a day if you seem to have added noticeable fat.
YOU HAVE TO TRACK WHAT YOU EAT, but focus on the weekly average, and try to HIT the goal average, not beat it by being under the calorie goal.
As far as bodyweight gain, the neat thing is that you will probably look better. 5 pounds of real muscle will go a long way (5 pounds is like 10 CUPS of muscle, so imagine adding 10 cupfulls of muscle tissue to your body.
1 pound a week would be ideal, but if you cut carbs, you may lose 5 pounds off the bat, so don’t worry about tracking weight until week two.
Of course, we would need to know your currect calorie intake to give real accurate numbers.
