New Discovery About Weight Loss

New Discovery About Weight Loss
It is generally accepted that blood leptin levels are critical to weight loss (and gain.) Sure, increasing leptin would reduce appetite--but how do we do that?

Scientists at The University of California, Davis, and the USDA Human Research Center* pondered the question. Then they went to work. They used human volunteers to discover how different foods trigger or repress leptin levels. What they found was when eating foods with glucose (sugar,) leptin increases along with insulin, both of which help regulate appetite.

"However, when we eat or drink foods with fructose in them--like soft drinks or some fruit beverages--our bodies may produce less leptin or insulin. As a result, we may still feel hungry after eating," they wrote.
