When I first began Keto I would snack on cheese and meat sticks/beef jerky and the such. I like eggs to...but that's not your jam...I understand. Anyway...I quickly discovered that after a couple of weeks (yeah...I had to learn the hard way) that you can't snack on keto like you would a regular diet. I was getting sick to my stomach because of the amount of fat and protein I was eating.
Here is the thing...items that are made of highly refined carbohydrates (chips, pretzles, and such) do not satiate your hunger. Actually, there is evidence to suggest the opposite, that processed foods actually make you want to eat more food. One of the reasons the Ketogenic Diet works really well, is that it works with your hunger signals. I guarantee it...three ounces of beef or chicken or cheese will much more satisfying than three ounces of lays potato chips or Dorritos...AND it will hold you over longer. Okay...I'm not just eating a three ounce steak...but you get the idea.
Keto really made me assess how I ate and my relationship with food. I really discovered when I was hungry and when I thought I was hungry. It got to the point that I just didn't snack. If I was hungry...I ate. Plain and simple. You will find that this approach will keep you from snacking. Now...there are some that say that you need to eat six small meals a day in order to...blah, blah, blah. Sure...I am certain that there are some people that need to do this. When my wife was pregnant...yeah...she needed to eat more often I get that. But an otherwise healthy person should be able to go six, eight, ten, twelve, or even 24 - 36 hours without having to cram a ho ho down his throat.
To answer your question...I ate a lot of cheese...I mean A LOT! That is if I felt that I absolutely needed something and couldn't eat a meal. Most of the time...and ounce of cheese will do the trick. But I just didn't snack. And I got to the point that IF I ate breakfast...it was just coffee with cream, collagen powder and some coconut or MCT oil. That was more filling than any bowl of cereal can be.
I am sure it will get discussed on this thread later...but dieting to get healthy and lose weight is more than just calories in and calories out. There is a lot more at work in your body. Insulin, glucose levels, cortisol, fat cells, proteins, types of fats, etc, etc, etc.
I hope this helps at least a little.
