My son cut about 5 lbs for Tulsa... (and has kept it off)
Everything sugar free. Flavored water is one of the kids' favorite drinks now.
100 calorie packs (including microwave popcorn) are great for snacks.
Fiber One cereal for breakfast every day (it actually tastes great) to keep him regular.
Whole grain carbs, leaner meat selections, and monitor sodium intake to avoid retaining water.
You can definitely do this without your wrestler feeling fatigued or deprived.
Good Luck
