Your Body Wants You to Stay Fat

Your body doesn't want you to lose weight, scientists say, and makes it tough to keep off pounds lost. Scientists tell the Los Angeles Times that brain and hormone cues increase post-diet as natural processes try to get that old figure back. And while research into the heavy issues is still ongoing, exercise and medications are seen to help.

Instead of vowing in vain never again to eat as much, successful dieters tend to exercise more and watch what they consume. And tricking the mind is necessary too: "Weight loss alone is not a realistic goal," said one researcher, emphasizing permanent lifestyle changes. "The key is to get your brain back on your side."
