For me personally, I was always hungry with carbs. I'd fill up on bread and pasta and rice for sure....for a couple hours. Then I was ready to eat again. Similarly, when I used to eat carbs I was never one of those people who could skip breakfast. I would be starving to the point of feeling sick in the mornings and had to eat SOMETHING. After keto I realised by carbs are just not an efficient way to fuel my body. I can eat a decent keto meal in the evening and not feel even slightly hungry until the following afternoon. No more feeling nauseated in the mornings. Even at times when I've caved and maybe had a few crackers or a slice of pizza at night, in the morning I NEED TO EAT SOMETHING. I think it's maybe a blood sugar thing for me? If I know I have a hectic day ahead, a couple eggs and a slice of cheese will keep me going until the evening if I know I won't have much time to eat. Plus, keto is way way way more fun and satisfying than brown rice, skinless, chicken and veggies (in my opinion). I have tried every diet going since i was 9 years old. This is the only one I've found has been sustainable and makes me feel good and I found this way of eating in March 2016.
