Eat Every Four Hours

Eat every four hours ― breakfast, lunch, snack, and dinner. This way of eating keeps your stomach from rumbling and your metabolism happy. Starve yourself for any portion of the day and you cheat yourself out of a bump in your metabolic rate. When you first start to eat every four hours, you might find that you're not very hungry when the four hours are up. But that's the idea ― you don't want to be famished by the time you eat again. You want to head off extreme hunger, which is a signal that your blood sugar has dipped too low and will lead to cravings and overeating.

Alternative Workout!

If you’re trying to get into top-notch shape, consider alternatives to a standard gym routine. Disciplines such as yoga, tai chi, and Pilates offer additional benefits, such as flexibility and balance.

Just Quit It!

Okay, here's a no-brainer: Smoking is bad for you. But you probably never suspected some of the ways in which it's bad. This destructive little habit affects a slew of endocrine glands — pituitary, thyroid, adrenals, testicles, and ovaries — in addition to the lungs, heart, brain, and, oh yeah, every other cell in your body. To give you a breakdown of the metabolic risks, smoking helps cause insulin resistance and drives up your cortisol levels. It can make you infertile and throw your body into menopause years before your time. Smoking is also a huge risk factor for problems with your thyroid. Think quitting will make you fat? I have news for you: Smoking fills your body with a number of pollutants that not only won't help you lose weight but will make you fat. Seriously, people, just don't do it.
