Last 3 weeks I've cut 12 lbs using the following, another 10-15 and I'll be stoked. Here's the plan I'm following:
Breakfast: 1 small entree, 1 fruit, 1 whole wheat/grain carb, 1 protein OR dairy.
Morning snack: 1 fruit, 1 protein OR dairy
Lunch: 1 small entree, 2 vegetables
Afternoon snack: Semi-healthy snack aka low fat pretzels, fiber bar, etc
Dinner: 1 small entree, 2 vegetables, 1 fruit, 1 carb, 1 small fat
Dessert: same as afternoon snack.
The keys to this one are LOTS of small, healthy portions all day to keep the metabolism up, and low calorie intake. I'm averaging 1400-1500 a day.
Oh yeah, exercise too. Personally I go to the gym a couple days a week and golf a couple times a week. Mostly it's just being active in any way.
