Intermittent Fasting: Is it healthy?


I've been hearing a lot about intermittent fasting on the internet lately and I was wondering if this was a healthy way to lose fat? From my understanding and research, intermittent fasting doesn't necessarily change what you eat or how much you eat, but WHEN you eat. For example, instead of eating 3 meals between 8am and 7pm, you'd eat all three of your meals between 12pm and 8pm. There's some science to this that I've read, but I'm not confident enough to explain it myself yet. I figured it would help because you'd get less cravings and avoid excess snacking because your meals are closer together, and it's a lot easier than calorie restricting since you still eat the same amount of food, just at different times. I've attached an image I found explaining intermittent fasting if you need more information. I'm just curious if this is just another fad diet that isn't actually good for you or if it's actually effective and healthier.
