Scientists are trying to develop an injection that will make you crave and eat less junk food and help you lose weight and reduce your risk for developing type 2 diabetes. Sounds too good to be true but it may not be. They have found a protein, called GDF15, that naturally regulates the body weight in humans and animals. The protein has be tried before but it breaks down too quickly in the body for it to have the desired effect. Now, a team had found a way to make it last longer in the body. When it was used on fat monkeys it made them eat 40% less and, with weekly injections, they lost 10% of their body fat in 6 weeks. That’s right 10% body fat loss in 6 weeks from a shot. They were also at less risk of developing type 2 diabetes and there didn’t appear to be any adverse side effects in the monkeys.
