Energy balance

Short-chain fatty acids (SCFAs) produced by gut bacteria have complex effects: while generally beneficial for blood pressure regulation via GPCR activation, increased production in obesity may contribute to calorie harvest and weight gain.

Fiber is good for your heart, but if you are struggling with weight, be aware that your gut bacteria might be extracting more calories from your food. Focus on a balanced diet rather than just maximizing fiber intake if weight loss is a primary goal.

An increased production of SCFAs in obese individuals might contribute to additional calorie harvest from the diet, potentially leading to weight gain... In the context of hypertension, SCFAs have mainly shown beneficial effects, especially acetate, primarily by activating G protein- coupled receptors (GPCRs)...
