I am trying to think ahead to after I lose my weight. How do people gain the weight back? I have noticed I still "bounce" back a pound or 2 now and then already and I only eat around 800 calories a day. How is it possible to gain weight back? do our bodies naturally gain weight back easier after we have lost? will we gain eating a smaller amount? traditionally we are told people need around 2000 calories a day to function normally and anything over could be stored as extra weight. will we gain even if we never hit that 2000 calories in our life? or do our bodies get used to eating 800 calories a day resulting in weight gain if we eat 1200 calories or 1300 calories? I am not very good at explaining my question. ultimately I want to know if we have trained our bodies to expect so few calories that they will hold on to any "extra" calories they get and turn them into weight gain even if it is still lower than a normal person's daily intake.
