The "keto flu" can be hard but you can get through it. There is a lot of conflicting information out there. Some people don't eat dairy but I do. Cheesesticks are my favorite snack because they're so easy to scarf down. What I try to stick with is homemade meals and cut out the processed food. That is a huge part of this diet that a lot of people overlook. I try to to lots of eggs, meat, veggies, and avocados. I try to meal prep as much as possible for the week. For instance, I make a frittata on Sunday that I can just pop in the microwave for breakfast. I eat leftovers for lunch at work as well. I do eat nuts, specifically macadamia, walnuts, and cashews, which is where I get the majority of my daily carbs from.
