Your hormones betray you
When you shed pounds, it's more than just your outside appearance that changes; inside, your body is making a dramatic shift. Sadly, it's not in your favor.
"As you start losing weight, the hormones in your body that regulate your weight change, so that appetite and cravings are actually stimulated in your brain," Dr. Grunvald says. "Some of this is subconscious, but as you lose weight, you are driven to eat more."
Perfect. Just as you're getting your junk-food habits under control, your brain plays tricks on you to make you want entire meals of chips, cookies, and pizza again. If it's hormones, there's NO WAY TO STOP THE CRAVINGS, right? Fortunately for you and your teenage self, you're more than your hormones -- being aware that your brain is playing tricks on you is a good first step, but if you need help combating cravings, check out these simple, yet effective tips.
Your metabolism fights back
You'd think your metabolism would adjust to your new, fitter body, and work in your favor to help you burn calories. Unfortunately, like your hormones, the complete opposite happens.
