There's a way you can naturally suppress your appetite and boost your metabolism with no negative side effects. It's called regular exercise, which means exercising five to seven times per week, not just intermittently.

As Smart Medicine for Healthier Living explains, exercise actually affects the hypothalamus' appetite control system:

"The appetite-control center of the body is the hypothalamus, or 'appestat,' the portion of the brain that tells the body when it is hungry and when the stomach is full. The appestat's hunger signals are triggered by specific levels of certain substances in the blood, including glucose, serotonin, noradrenaline, adrenaline, and dopamine. Physical activity reduces the levels of the hunger-stimulating chemicals that cause the appestat to start the stomach growling for food, and increases the levels of the chemicals that signal to the appestat that the body is humming along at peak efficiency and doesn't require food. In fact, research indicates that exercise can inhibit hunger for as long as six hours after a high level of physical activity" (Zand, Spreen and LaValle).

This means that you won't have to ignore painful hunger pangs or tempting food cravings because, with regular exercise, you won't have them as often. Along with helping you cut the amount of calories you put in your system, exercise can also help you burn the body fat that you already have by increasing your metabolism. Unlike stimulants, which increase your metabolism at a price of jitteriness and sometimes even heart palpitations, exercise naturally boosts your metabolism both while you're doing it and even when you're resting, so you'll be burning more calories even when you sleep.

How is this possible?

Exercise builds muscle, which naturally burns more calories at rest than fatty tissue. Plus, muscular thighs and abs look better than fatty thighs and abs, so exercising enhances your physical appearance as well.
