Your moment-to-moment weight can ultimately be determined by a simple equation: calories in minus calories out.

How your body handles stress, calorie combinations, seratonin in the brain, hormones, sugar management, inflammation, and chronic disease can all influence how your body works with that equation.

Combining sugar and fat together changes the types of bacteria that live in the small bowel. That can influence appetite and weight.

Not only can the brain influence hunger and digestion, the gut can influence the brain on the same things. Changes in the gut flora can impact the brain, affecting your memory, mood, and appetite. Fat-sugar combinations influence the brain the most.
