Exercise alone can boost your metabolism by enhancing thermogenesis (heat production in the body), but this effect can be assisted by a well-formulated thermogenic nutritional supplement. Such and energy-boosting formula would ideally contain a variety of natural substances that support the activity of the thyroid gland (which regulates metabolism), increase the burning of fat, regulate blood sugar and insulin levels, and suppress appetite. Again, a local health food store that specializes in supplements should be able to help you find the right one your physician when you consult with him or her to starting the fitness regimen. Ingredients to look for in a thermogenic formula iodine, tyrosine, green tea extract, banaba, and bitter orange peel extract.

The mineral iodine and the amino acid tyrosine and the amino acid tyrosine are important thyroid regulators. Abnormalities of iodine metabolism, which can result in thyroid disease and obesity, can be prevented through ingestion of kelp, a whole food supplement that provides iodine to support the thyroid gland and balance metabolism. As a direct precursor to the thyroid hormone thyroxine, tyrosine is an important ingredient in weight loss, one that also helps regulate appetite.

Green tea extract has garnered lots of acclaim in recent years following studies that show its potential effect in enhancing metabolism and aiding fat oxidation. Studies also show that it can help control body weight by helping to reduce blood fats-cholesterol-as well as aiding in blood sugar balance.

Banana, in addition to being found in lean muscle mass formulas, may also help regulate blood sugar levels. That is why it's often found in thermogenic formulas. Bitter orange and peel extract contains compounds that help stimulate metabolism, as does the South American herb mate, which also suppresses appetite. Other natural ingredients that may assist in weight loss include bamboo leaf extract and the natural brain chemical DMAE (short for dimethyl-amino-ethanol).
