Grazing isn't terrible as long as it isn't carb/sugar snacks. I went through that phase and would eat beef jerky or some other low carb snack or coffee.
How you tried bulletproof coffee? Coffee, butter and heavy cream.
I added intermittent fasting a couple years ago and don't eat after dinner (around 5-5:30PM) until breakfast (10-11AM).
Some days are still hard but the results in my health keeps me going.
