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…
any unhealthy side effects of only eating one meal a day? what if that meal is 1800+ calories?
If you make a regular meal, one meal a day nets a negative of 1300/1500 calories per day, which will cause considerable muscle tissue loss (note how the parent writes "losing weight", not "losing fat", but also "yes, I have significant fat even at 150lb and 5'10"), besides having no energy.
If you make instead a massive mels, you're going to give a massive glucose shot to your body. I haven't gone to such extreme, but the times when I happened to do something similar (one huge meal, even with an overall negative daily intake), I ended up accumulating fat rather than losing it. I suppose that in a calorie deficit context (=dieting), the body takes advantage of a huge meal to build some deposits up (and unfortunately, deposits are everything except muscles...).
Dieting's hard, there are no cheap tricks, unfortunately.
