I can’t stress this enough. You have to make things easy on yourself if you want to succeed. By preparing food in bulk you will have 2 to 3 days’ worth of food already prepared. You don’t need to worry about cooking a new meal every single time you want to eat. You don’t have to come up with a new recipe for each meal. You can just open the fridge, grab your food, and be ready to eat in minutes. I normally grill around 20 chicken breasts at once, and will also steam between 8 and 10 sweet potatoes. Now, I don’t normally just have a plain chicken breast with a sweet potato, but if I needed to just eat that then guess what, it is there for me. It's quick, convenient, and ready to provide me with a perfectly balanced meal in record time.
So, practice cooking in bulk as much as you can. Make sure though that the type of food you cook can last a few days and won’t begin to spoil. Doing just this one thing will remove a HUGE hurdle when it comes to eating right on a consistent basis.
