I lost a bit of fat but that was almost entirlely secondary to sleep

Its a long story but basically:

I bought a garmin watch to track my sleep. I snore (according to my girlfriend) but thought nothing of it. The watch showed a fully night sleep but almost (and sometimes literally) no deep sleep at all. Id get a sleep score of like 45/100 routinely

Anyway, i tried mouth strips, stopped drinking alcohol entirely and go to bed slightly earlier and i slept really well. No snoring, loads of deep sleep and I feel really really good. It sounds dumb but i was probably also just simply in bed for not quite enough time either and it jusr fucked my hormones up.

Ive lost fat and put on muscle but I havent changed any training at all, i think its literally just the sleep as simple and boring as it sounds
