When talking about weight loss, specifically, a couple things to keep in mind: Key is to eat at 500 calorie deficit every day. Google TDEE calculator to learn more. Exercise and fasting can both help a bit, but it all comes down to calorie intake. I've read a lot about this, and consensus is around 80- 90% of weight loss comes from limiting calories. Unless you run a LOT. Fasting is just one very effective way to reduce calories. Type of food doesn't matter either, you could eat nothingbut doritos and skittles. Secondly, you can't target weight/fat loss. You can do 5,000 situps a day, it won't help you lose weight in your gut. As you lose weight, it comes off where it comes off. That's mostly genetics. FWIW I've lost 47 pounds during covid, starting from 225. Still drink a pretty healthy amount of beer during weekends, still have pizza, fried chicken, etc. Working out, sure. But I think the big things have been cutting the size of my lunch in half, and trying to limit night time snacks.
