HCG, or Human Chorionic Gonadotropin, is a hormone produced during pregnancy by the placenta after implantation, and doctors sometimes prescribe it for fertility issues. But this hormone has also gained popularity as a weight-loss supplement — and using it as such can be dangerous. In fact, the U.S. Food and Drug Administration (FDA) warns against purchasing over-the-counter hCG, as these supplement products are illegal. (34)

For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
You will likely lose weight on any diet if you eat less than 910 calories a day. But losing 10 pounds in 3 days is both unlikely and unhealthy. To lose just 1 pound of body fat, you need to reduce your daily calories by about 500 a day for a whole week. That’s giving up 3,500 calories over the course of 7 days. To lose 10 pounds in 3 days would mean decreasing your calorie intake by 35,000 calories in just 3 days! The Academy of Nutrition and Dietetics recommends a slow and steady weight loss of no more than 1/2 to 1 pound a week. Otherwise you are losing muscle and water, as well as weakening your bones. You also are much more likely to gain it all back.
Calories are an important part of your weight-loss journey, but so are the foods you choose to spend those calories on. It may not come as any surprise, but a 2011 study published in the New England Journal of Medicine found that people who fill their diets with fruits, vegetables, whole grains, nuts and yogurt tend to be thinner than those who eat more junk such as soda, potato chips and processed meat. Eating more fruits, vegetables and whole grains may help you eat fewer overall calories, which helps with weight loss. These high-fiber foods slow digestion, holding off hunger. As for yogurt, the researchers theorize that the friendly bacteria in the fermented food may change the bacteria in your gut, which may help prevent weight gain.
This eating plan promotes an average loss of one to two pounds per week. You’ll eat portion-controlled, pre-packaged meals and snacks; you can add your own fresh fruits and vegetables. Then, you’ll slowly introduce regular meals with the help of weekly counseling sessions. Jenny Craig does have some scientific evidence to back it, and dieters say they like the personalization and support of weekly meetings with a counselor. On the downside, the program can get expensive, and it uses a lot of processed foods with long ingredient lists. This plan isn’t meant for children under 13 or people with food allergies.

Notes: Defrost the shrimp under cool running water and pat dry. In a nonstick pan over medium-high heat, toss the shrimp with a little all-natural cooking spray, and cook until bright pink, tightly furled, and warmed through. Chop and steam the carrots and broccoli until tender-crisp, about 5 minutes for the carrots, 3 minutes for the broccoli. Drizzle everything with the teriyaki sauce and sprinkle with the sesame seeds.
