Weird tips like that? No, no definitely not. Just eat less man. It's pretty straight forward. Just eat one meal a day (lunch) and you'll see the weight fly off. It's what I did for a bit and lost the weight quickly. You'll lose 5lbs/month easily even for people who have a relatively lean body mass already. (Easier to lose a lot of weight when you're heavier because your BMR is high to begin with) I've done it as some…
I agree with you but wait what, that'd be 178 cm / 58 kilos? That's bordering on underweight: it doesn't feel right (or I'm converting it wrong?)
My first advice to people would be this: check your BMI first, and if you're perfectly in the middle then certainly do not get close to underweight.
Besides that: I don't drink much alcohol and do intermittent fasting (skipping meals like you do) and I've never been neither overweight nor underweight. To me it's all about discipline.
