mindi s · Yahoo User

I've been on Slim Fast to lose weight for awhile now. I've lost 20 pounds and weigh 195 age 21 5 foot 4 inc tall.I'm going to go to Walmart to get protein shakes but im worried about weight gain. Last night I asked a question about if I could get muscle and live off Slim Fast still and someone said to take whey protein and take such and such amount and how much it was calorie wise and now im a little worried about gaining weight or staying even weight wise while getting muscle.Each day I have two shakes 480 cals in total on top on off playing DDR for about an hour everyday (HEAVY aerobics basically) for those who play DDR or know anything about it I play on Standard mainly. I'm planning on lifting weights 6 days a week upper and lower one day with Sunday off.How do I do this to get muscle tone and continue to lose weight. I cant stop the shakes I got fired and I'm looking for a job and they're all I can afford right now.
