During most of evolutionary history, the biggest danger to any creature’s survival was starvation. Animals have evolved to handle the energy available to them with great care, so they can maintain enough energy to stay alive and to pass on their genes to further generations. The last few generations of humans have gone through a dramatic shift where excess calories are becoming the main problem. Unfortunately, the design of the human body can’t adapt as quickly as it’s still working hard to try to avoid weight loss.
For people who are looking to lose weight, this is a serious problem. You’re living in a body that has a whole array of metabolic tricks that are designed to help it avoid using up more calories than it’s taking in, so it can survive as long as possible. One of the key elements in this strategy is a hormone known as leptin. A hormone is basically a chemical that’s released into your bloodstream to allow different parts of your body to communicate about what they believe is going on. This particular one is used to signal that you’ve gotten enough food, and that it’s safe to burn energy.
This is important because that same hormone has a lot to do with whether you can lose weight and how difficult the process is. If you cut back on your calorie intake, your leptin levels will fall to reflect the fact that you’re no longer getting enough to eat. This will make you hungrier and more likely to have cravings and will also signal your body to do its best to avoid burning more calories than absolutely necessary. These factors work together to make weight loss very difficult at best, and potentially even almost impossible.
If you take supplements that are designed to increase leptin production, though, you can turn the way your body works to your advantage. Boosting that hormone will help to tell your system that everything is all right and it’s safe to burn calories. It’ll also stop your body from frantically signaling that it needs more food. This makes weight loss a lot easier and more comfortable.
