The tangy-sweet sip that triples weight loss

To get the perks, Dr. Pescatore suggests supplementing with 1⁄2 tsp. of glutamine (like Life Extension L-Glutamine Powder, $17 for 50 servings, lef.com/ffw) before meals and whenever cravings strike. Promises Dr. Pescatore, “The fluffy white powder dissolves easily and is virtually tasteless.”

And while you can stir glutamine into water, juice or even green smoothies, Virgin has found that her clients get the best results by whipping up a concoction that she calls Lemon-Aid. “The sour taste of lemon juice instantly mutes your sweet tooth,” she says. “And when you drink lemon juice 30 minutes before a meal, it lowers your bloodsugar response as well.”

To make a serving of the cravingcrushing treat, combine 6 oz. of water, 4 Tbs. of lemon juice, 1⁄2 tsp. of glutamine powder and stevia (like SweetLeaf Sweet Drops SteviaClear, $4 for 50 servings, Vitacost.com) to taste. “However you sip it,” Virgin says, “glutamine will crush your cravings in their tracks and make lasting fat loss effortless!”
