I'm an 18 year old girl, 5'3 and 102 lbs. MFP tells me I should eat 1520 calories a day, and my Apple Watch tells me I only burn ~1500-1600 calories a day in total. However, I track around consuming 1700-1800 calories most days and sometimes I even lose weight on this amount.
I work out at home for about 20-30 mins 5-6x a week and go for a 30-40 minute walk every single day. I sit a lot at school but when I'm not at school I stand whenever I can and am constantly moving.
How is it possible that BMR/TDEE calculators, MyFitnessPal, AND my Apple Watch all tell me I should consume 1500-1600 cals bc that's how much I burn supposedly, yet I eat more than that and don't gain weight (& sometimes lose weight)? Is this bc I'm young so my metabolism is fast? Super confused & can't find anything online about this.
