| 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. |
