About rapid weight loss
Although obesity is becoming an epidemic there is a reasonable concern for significant weight reduction, the risks of rapid weight loss are many, including gallstones, malnutrition, dehydration and electrolyte imbalance. Other side effects include headaches, irritability, fatigue, dizziness and constipation. Care must therefore be taken in buying weight loss products or diets that promise rapid weight loss.
Types of weight loss products
The FDA does not regulate OTC weight loss products. Consumers must be warned that marketers may make their claims freely, usually with no research or proof that their products work.
Very Low-Calorie Diets
Medically supervised very low-calorie diets (VLCD) are the only proven method of safe, rapid weight loss because they are supported with scientific studies of people on these diets. People on this kind of diet consume meal replacement products that can safely produce 15-25% weight loss in 12 weeks if they finish the program. These meal replacement products usually come in the form of shakes or beverages which are easy to prepare and can be taken anywhere, without the need to count calories. However, they are quite expensive and should be professionally prescribed. Diet pills
Diet pills come in different types, such herbal diet pills and other medications that work by blocking the absorption of nutrients, increasing metabolism, or burning fat. Many are sold over the counter although some may be medically prescribed. Of these products, the statin Xenical is one which has been found to be effective in reducing fat absorption and promoting safe weight loss. However, it works slowly and one is advised to take it with diet and exercise. Despite being approved by the FDA, Xenical also has side effects related to liver injury and must be taken only for a short time. Diet supplements
Slimming teas, green tea extracts and herbal supplements abound in the market, claiming to be weight loss solutions. Most products claim to contain herbal ingredients that may have antioxidant properties and other health benefits. However, most of these contain harmful ingredients like stimulants and colonic irritants that initially cause diarrhea but later leads to constipation due to weakening of intestinal muscles. Final word
Before deciding to buy or use any of these products one must seek medical advice to avoid unwanted side effects and complications. Proper diet and exercise are still the best ways to attain healthy weight reduction. Reference
