Ann,
With all this talk about how much fat and protein, the key to LC and then being able to easily handle Time Restricted Eating (that is less than OMAD) is keeping your carbs very low. That's it. Jackie Eberstein, who worked for Dr Atkins and now Heal Clinic, focuses on older women who do have a harder time losing weight, and suggests a strict 20g total. https://www.dietdoctor.com/weight-l...f-women-over-50. Monday, at the support group meeting, she was talking about the fact she for the first time in her life she added some Time Restricted Eating with very positive results. So in this video she states she has no clinical experience with IF, now she is back at HealClinic and tried it herself, she is supportive.

It is unlikely you will become truly Fat-Adapted, and be able to do TRE of 24 hours without hunger unless you are. It is not ketosis, fat adaptation takes a month + http://www.tuitnutrition.com/2016/0...-a-ketard1.html Why Megan Ramos talks about exercising your fasting muscle...it takes practice extending your fasting time, but you should be solidly fat -adapted first or it will just be miserable.

In addition to keeping total carbs below 20g, you should consider checking your blood sugar after eating certain foods. You may find cooked veggies or artificial sweeteners make your glucose rise...and even though fit in 20g still would cause that hunger you have. Glenda has a good new thread in Media on it.
