It's Not a Willpower Problem. It's a Signaling Problem

Two hormones - leptin and ghrelin - decide when you feel hungry, and when you feel full. Your gut microbiome may be influencing them more than anyone realized. 

New research is pointing to a group of gut bacteria researchers are calling 'lean bacteria' species - strains observed in higher concentrations in naturally lean individuals. Studies are now looking at whether populating the microbiome with these bacteria may support clearer leptin and ghrelin signaling, helping the body recognize hunger and fullness the way it was designed to.

The formula on the next page walks through which specific strains are being studied, and why they're drawing attention.
