Fasting is an interesting subject. There's studies that show you'll live longer if you do some sort of fasting, as well as burn fat at an increased rate. I'd look into intermittent fasting. You eat the same amount of calories in a day as you normally would (whatever your desired number is), but you only eat in a 6 or 8 hour window, say from Noon to 6PM. You do this 7 days a week as far as I know. I've tried it the last week or two and it's not as hard as I thought. My body adapted pretty quickly. Apparently is doesn't decrease muscle mass, either. But maybe if you're looking to lose more weight at a quicker pace while still being safe, 24-hour fasting a couple days a week might be better. I don't know.
