Fasting

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.
