It partly depends on your metabolism. Some, like you, can't face going without breakfast, for example.That said, IF, according to definition, does not really exist until you eat only 1 large meal every 24 hours, all eaten within a 4-hour period. Some claim that alternate-day fasting is better, though this is disputed, that involves eating 1 large meal, eaten within 4 hours each 2nd day, eating nothing inbetween.
The key behind IF seems to be to spend as few hours digesting food. The idea is that constant digestion diverts energy-resources that could otherwise be used for healing/rebuilding, plus constant digestion slowly wears down the digestive system over time(which is partly why old peoples' digestive systems are usually so wrecked).
When I first started, even though I always hated having breakfast, I would usually feel an irrestible urge to have a little fruit between 11am and 2pm. I would then have 1 large raw meat meal in the evenings. Eventually, my blood-sugar-related issues resolved themselves and I was able to eat the fruit in the evenings along with all the raw meat, all within a 4 hour period. Though I always ate the fruit at least 30 minutes before the raw meat eating.
