Smoking cessation

Smoking tends to rev up your metabolism. The likely reason: Your body is forced to expand extra energy trying to detoxify itself from the chemicals. Unfortunately, this is a big part of why people experience weight gain after quitting. To help offset the metabolic dip, try exercising and chewing a combination of Nicorette and jot gums. Research reported in the American Journal of Clinical Nutrition found that men who chewed nicotine gum (2mg) spiked with 100 mg caffeine experienced a 10% increase in metabolism.
