It works. And while you're at it, take a peek at the nutrition labels on your foods. Knowledge is power. Be aware of what you eat, how much, and what it equals to in your calorie consumption needs.
We gain weight by mindlessly eating more calories than we burn. Start recording every bite you take and it's no longer mindless.
So there you go! Write down what your eat to lose weight. Now wacky diets or supplements. Doesn't cost a thing. It's just so simple.
