I have lost 25 lbs in just a few months. Mostly I am doing two things: 1. wait five hours between meals, no snacking, no cheating. When you hit that point at 3 hours when you feel like you're starving, drink water. It's like a smoking craving; if you can endure the craving for just a few minutes it will go away. And 2. Like @Kiki says, exercise five minutes. I do it after I eat, I just gently walk in place because of my ankle. Sometimes I do sit-ups and leg lifts in my recliner. No kidding, 25 lbs and still losing. I feel awesome. I recognize my body again!
I think I would die if I waited that long between meals
