I use the Levi Reloaded and DCP stack. Throw in fish oil and maybe green tea and she should be good.
As far as the diet. I eat good carbs like sweet potatoes, oatmeal mixed with a scoop of chocolate prtein powder and a tablespoon of Natty Peanut butter mixed together. Brocolli and aspargus are good. And lean protein like tilapia, tuna, chicken.
My trainer wants me on 6 meals a day with 20 grams of protein a meal, I weigh 122lb. So 1 gram of protein for every 1lb she weighs.
Drink plenty of water, use weight training to put on muscle. Which burns fat at a resting rate.
Cardio until she drops to a weight she is comfortable with. But weight training definitly.
