I’m a short person. I’m also sedentary and classified as overweight but not obese. As such, my TDEE is around 1600-1700 calories. So, to lose weight at the pace I’d like, I have to restrict myself to 1200 calories a day.
My partner is taller, fatter and has more muscle mass than me. He’s talked about wanting to lose weight to get healthier, but when it comes down to it he won’t do anything. Which is baffling to me, because his TDEE is high enough that he could eat waaay more than me and still lose weight.
Ugh. It’s frustrating.
Maybe it helps to think about the fact that everything scales with size so while his target kcal for weight loss might make you fill full (or maintenance) but for him it might be as challenging as your 1200 kcal limit.
Overall all you can do is do your thing, potentially introduce healthier habits like substituting rice with chick peas etc. but eventually he is responsible for his body. (I am also responsible for my weight gain).
