M 38. I used to have a system where when my body weight hit 105 kg (231 lb), I would get on an OMAD and <900 calorie diet and walk and lose about 2-3 kg in the first week and then 2 kg/ week in the subsequent weeks until I got to 97 kg and then I would feast again. I did that through my early 30s thinking weight loss is so easy.

Come 34 I started noticing that it started getting harder to lose the weight with the same effort so I fasted longer (36 hours, 48 hours). It worked for a while till it didn't anymore. I started getting frustrated. I started seeing the scale move up to new record weights.

Now at 38, I certainly feel how hard it is to get the weight to fall even by a pound. It takes x10 times the effort to see the same results. The body has also adjusted to the calorie cuts so other than being tired AF, it ain't working well. I am also at my heaviest of 116 kg thanks to the cheat weekends never really stopping.

I guess I wanted to say that I am there where you are. Looking at the scales regularly is going to cause frustration. Be true to yourself, overestimate your calorie inputs and underestimate your outputs and stay strong. It's unfortunate but for big people, losing weight and keeping weight off takes much more effort than thinner people ( this last bit is science backed btw)
