Eat healthily but allow yourself the occasional treat. If you go too crazy, you won’t lose weight.

You will find that if you are fasting properly and losing weight your desire/ inclination to stuff yourself on none fast days will reduce.
This is an automatic response if your true wish is to lose weight and be healthier. You seem preoccupied with snacks. They cover a wide variety of “edible” foods. Maybe you should note what you are snacking on for a couple of days. It should tell you if you are overdoing the cals

Steward, many of us eat nothing for 24 hours then have 300-400 cals for “dinner” then fast again until morning. Others go 36 hours without calories (but plenty of water) twice a week. You get used to not eating. 🙂 The 500 calories is a MAXIMUM. It is not a minimum!
To lose weight, we need to rethink our attitudes to food: type, portions, frequency. Getting overweight took years of “effort”. Losing it again takes determination. Most people think about food most of the time, but it doesn’t mean we are hungry or that we have to eat it! All the best. PVE
