Your system responds to stress by producing the hormone cortisol, which decreases your metabolism and encourages your body to store fat in your abdominal area. A study at the University of California, San Francisco showed that when stressed women were left along in a room with unlimited access to food, they ate 57% more than those less stressed. The #1 way to drop your stress level is exercise. You may also be able to lower stress levels with supplements. Most experts recommend getting at least 500mg of omega-3s and about 900 mg of vitamin C a day.
Vitamin C is naturally found in fruits and fruit juices (especially citrus), potatoes, broccoli, bell peppers, spinach, strawberries, tomatoes and brussels sprouts. Omega-3 rich foods include flax seeds, walnuts, salmon, grass-fed beef, soybeans, halibut, scallops, shrimp, and tofu.
