Weight-loss patches release effective herbal substances into the bloodstream through the skin. Manufacturers promise that they suppress appetite, increase metabolism and enhance energy. Whether or not they have any beneficial effect on weight loss has not, however, been clinically proven.
Action
Transdermal patches are designed to increase metabolism by stimulating the thyroid gland. Calorie burning is accelerated.
Each diet patch has a 24-hour action. The process must be repeated for several weeks, as there is no magic formula for weight loss.
Diet patches are said to work very well alone. For better results they might be combined with a weight loss program.
Composition
Most patches contain the following:
- Fucus Vesiculosus has fat-burning properties. It contains a high concentration of iodine, which stimulates the thyroid gland.
- Guarana contains caffeine, a metabolic stimulant with fat-burning properties.
- Garcinia Cambogia: Its active ingredient is hydroxycitric acid (HCA), which prevents the conversion of carbohydrates into fat by inhibiting the action of the enzyme citrate lyase. It also suppresses appetite.
- Chromium Picolinate helps to regulate insulin. It balances blood sugar levels which burn fat, produce energy, maintain lean muscles, and use up cholesterol.
Disadvantages
Diet patches have not been proven effective. Official and governmental health associations do not recognize them. Most patches are based on iodine compounds. Exceeding the acceptable maximum iodine level in the body can pose a health risk. And patches can have other negative effects on health. What else can we expect from products which are not officially approved and have not been through adequate testing?
Regular exercise and a reduction in calorie intake continue to be the safest methods for long-term weight loss.
