Your Gut Flora Help Control Your Appetite

If you look at the gut microbiome of an obese individual it’s very different than the gut of a person with a lean body mass.
In animal studies, GI bacteria seem to affect both appetite and metabolism. New research suggests certain “bugs” can promote a feeling of fullness. A 2015 French study found a “good” strain of E.coli pumps out proteins that stimulate the release of the satiety hormone peptide YY about 20 minutes after a meal.
You can help support the healthy micro-organisms in your gut by eating foods that friendly bacteria like to feed on — think high-fiber whole foods (fruits, vegetables, legumes) and probiotic-rich fermented foods, like kimchi, sauerkraut, and kefir. Try making your own kefir by using this kefir starter culture kit.
Body mass index (BMI) is a measure of body fat based on height and weight. The BMI of an obese individual ranges from 30-39.9, and the BMI of a person with a lean body mass ranges from 18.5-24.9.
