Have you considered trying out having three meals a day with no snacking in between? While I usually eat only once a day and sometimes do a longer multi-day fast, that’s where I start with my recommendations.
Not hungry in the morning? Then skip breakfast. Eat lunch, then have dinner and stop. That’s how I started doing intermittent fasting. Quit snacking and set a time window when you have your 2-3 meals consisting of non-processed food. The cravings will subside once you’ve avoided high carb food for a few days.
Once you get used to not eating constantly, try out longer periods of fasting. The feeling of hunger is hormonal first and foremost and your body responds to your habits: you get hungry around the same time your body is used to being fed. Hunger subsides if you just fight through it. If you feel nauseous, either take electrolytes or just stop, eat, and try again later and take better care of mineral intake during your fast.
