Adam you are doing it right. Everything you are mentioning is about your kids. That is what will be remembered by them, get as much time as you can and even if you re not ordered to pay support you know you will pay your share.
I never liked keto for that reason...especially in stressful times. I have not dieted during my current 8-9 month ordeal....I found it hard to manage all of the diet rules. I have concentrated on exercising....much more satisfying for me to get the blood and muscles pumping to raise my self esteem.
I have dieted with with whole 30, paleo, some keto but in the end have found, more protein, less carbs, balanced diet works just fine. As long as I exercise regularly, I can cheat 2 days within reason and that keeps me in line the other 5 days.
Hang in there buddy!
