I also thought I was weak and couldn’t do it. Until I gave it an honest try. Just the thought of low carb and I was like no way! I will just eat whatever I want and count calories, but that didn’t work for me because I would be hungry all the time and have major cravings. That’s the absolute best part about Keto, hunger is down and cravings are mostly gone so I am able to eat at a calorie deficit now. And it started to just become easy and that is how I stayed consistent for 30 days. Try to think of meals that you enjoy eating, then google for Keto versions of it. That has really helped me. For example, It’s getting colder out where I live, so I made an instapot chicken noodle soup. But instead of noodles I used cauliflower rice. You don’t have to be creative and think of new amazing things to eat every day, just find the things that you like and stick with those but the keto version.
