There are about as many different strategies for breaking a fast as there are for fasting.
Carbohydrate spikes blood glucose, which spikes insulin, which rapidly brings down your blood glucose - making you hungry. I do not need to be on a keto or very low carb diet, and my regular daily carb breakfast (grain-free buckwheat muesli, live full-fat yoghurt and fruit) makes me hungry for lunch.
I break my 68-hour fasts with full-fat live yoghurt, as it is low carb, and helps your microbiome by re-populating you "friendly" gut bacteria. After a long fast, I would suggest that you to avoid eating carbohydrates (including fruit) in your first meal. See:
Dr Eric Berg:
Thomas DeLaurer has a different opinion (I think for younger people without hyperinsulinaemia):
If you binge-feast after several days of fasting, you can get refeeding syndrome, which can be fatal or serious.
Why do they rank the Keto diet worst for health?
