24 hour fasting?

Hello! I just started my weight loss journey as I’ve been trying to improve my overall health. I know that a lot of people swear by intermittent fasting, but what about the occasional 24 hour fast? I had lunch at 11:45 yesterday, and didn’t have an appetite when I came home so I skipped dinner. I feel fine this morning and am about to do cardio at the gym. I’m kinda hungry this morning but I figured it’s only gonna be 3 more hours by the time I leave the gym to make it 24 hours so why not? I’ve been drinking lots of water she has a cup of coffee this morning. Is this safe to do as long as I stay hydrated? I weigh 330, trying to get to 240 (goal my pcp set for me for now), so I have a lot stored up to burn off. Would this be safe to do maybe once a week?
