Citrus auriantium (bitter orange). A nutrient found in the peel improves the body's ability to burn fat for energy.

Theanine. This amino acid, extracted from green tea, decreases the production of stress hormones, which encourage fat storage.

Lipoic acid. A little-known nutrient found in red meat, spinach and broccoli, it improves the body's sensitivity to insulin, which helps the body store less energy from food as fat.

Conjugated linoleic acid. The omega-6 essential fatty acid encourages the body to use fat as fuel, which protects muscles from being broken down during dieting and exercise.

St. John's wort. This herb boosts the amount of the hormone serotonin in the brain, reducing cravings for sweets and junk food. Caution: Never take St. John's wort if you are taking an antidepressant, such as Prozac or Paxil, as it can decrease the drug's efficacy.

Kelp. This seaweed contains iodine, which helps keep your metabolism at a healthy level when you diet.

Digestive enzymes. Extracted from a variety of foods, they help break down foods and maximize the absorption of nutrients to keep your energy up.

Always consult a naturopath to make sure you're getting the right dose for the right amount of time.
