Fasting. We have all kinds of people fasting, wanting to learn about fasting, want to share their expertise or experience fasting, and general people with good vibes.
Anytime I've used keto I've also slid into OMAD. Keto usually leaves me with less overall craving for food so it's almost natural.
I'll typically just have some black coffee in the morning then not eat anything at all until around 4pm after work, have one meal then be good until the next day.
Works great for me personally but I assume everyone is a little different.
Interesting that it happened naturally. Were you doing something during the day that also kept your mind off food? ...like a stressful job? Also, what did a single meal consist of?
I never been a big breakfast person so I usually skip that even when not doing keto. And honestly I'm just not as hungry during keto as the things I typically like to graze on throughout the day are not keto friendly.
I personally stay away from the keto snack substitutes for just that reason, I enjoy not wanting to snack throughout the day. That being said, I use keto for weight loss and not as a lifestyle change so if I planned to stay on it long term I wouldn't be as adverse to keto snacks. I used keto 8 years ago to lose about 65lbs and typically once every year and a half or so I'll jump back on for 4 months as maintenance to keep me in the range I want to be.
As for what I eat for that meal it depends on the day. Typically just some type of meat and vegetable combination. Steak, pork chops, air fried wings, taco salad, eggs, bacon ect are all on pretty regular rotation. For veggies I've found that I can't get enough air fried broccoli or cauliflower, I love the stuff. I don't count the calories anymore but with one meal, you want it to be on the bigger side.
