Most low-carb diets advocate replacing carbs with protein and fat, which could have some negative long-term effects on your health. If you do try a low-carb diet, you can reduce your risks and limit your intake of saturated and trans fats by choosing lean meats, fish and vegetarian sources of protein, low-fat dairy products, and eating plenty of leafy green and non-starchy vegetables.
You need to be evaluated by a physician if you have any health problems, are currently taking any medicine or plan on taking any medicine, or plan to lose more than 15 to 20 pounds. If your weight-control plan uses a very low-calorie diet (a special liquid formula that replaces all food for 1 to 4 months), an exam and followup visits by a doctor also are needed.
The truth is there is no “one size fits all” solution to permanent healthy weight loss. What works for one person may not work for you, since our bodies respond differently to different foods, depending on genetics and other health factors. To find the method of weight loss that’s right for you will likely take time and require patience, commitment, and some experimentation with different foods and diets.
You’ve heard of a self-fulfilling prophecy? If you keep focusing on things you can’t do, like resisting junk food or getting out the door for a daily walk, chances are you won’t do them. Instead (whether you believe it or not) repeat positive thoughts to yourself. “I can lose weight.” “I will get out for my walk today.” “I know I can resist the pastry cart after dinner.” Repeat these phrases and before too long, they will become true for you.
Yes, but probably not as much as you might hope. A review of studies on five major FDA-approved prescription medications for obesity, including orlistat, shows that any of them work better than a placebo for helping people lose at least 5% of their body weight over the course of a year. Phentermine-topiramate and liraglutide had the highest odds of making that happen.
