Suggestions please. I'm a slim guy who does a bit of weight training to build muscles and I'm pleased with the results I get when I work out. What I don't like is my belly. I used to have a 6-pack a few years ago but now I have flab. I want my rock hard abs and flat belly back without looking like a skeleton!

lower the carb intake, increase protein. lower total calories about 10% to start cutting. lift fairly heavy, lower reps (not light and high reps...that's a myth).

you basically have to trick your body into "needing" the muscle you already have, while creating a small calorie deficit, mostly from carbs (the body's favorite energy source). keep carbs extra low on days you're not weight training (and increase protein/fat those days to make up for it).

this kind of strategy has worked for me in the past. didn't have to cut too many calories...just the 'right' kinds of calories.

Get a good protein intake like 1 pound per bodyweight. Actually its 1 gram per Lean Mass of weight but a little extra protein won't hurt you. Eat 5-6 meals a day to keep a good protein flow and nitrogen balance throughout your body. Drink plenty of water to get rid of extra water retention.

To keep your muscle lose your weight slowly; like 1 pound a week. You gonna lost a good amount of weight the first 3 weeks because of water retention but after that it shoud slow down.
