re: Fat Shaming: As a Society We Need to Do it More

Calories in/calories out determines your weight with a minor correction for absorption.

Things like metabolism and diet do impact how hungry you are. In theory you can lose weight steadily eating 1500 kcal/day worth of gummy bears - but it would require a superhuman level of discipline to deal with that level of constant hunger. That’s where tracking macros and understanding metabolic processes come into play.
