If you’ve tried multiple diets, reduced your calories, eaten your veggies, worked out faithfully at the gym, and yet nothing seems to change over the long term, you might be tempted to try out OTC weight loss supplements. Most of the medications work by reducing your appetite so that you eat fewer calories, reducing the absorption of your food, especially fat, increasing your energy expenditure, by boosting your metabolism and mimicking calorie restriction. However, obesity drugs have a somewhat controversial past, and some have been removed from the market due to dangerous side effects or the potential for abuse. If you’re already be on other medications, this particular medicine may not go well with it so check with your doctor. Obesity medications can be expensive and may have serious side effects that have not yet been brought to the fore. The effectiveness also varies from person to person, and moderate, short-term weight loss is not always ‘success’. Also, like use of any long-term medication, it needs your doctor’s surveillance. If you choose OTC weight loss medicines, you need to keep these factors in mind.
