How to Keep Keto Cheap and Easy
You don’t need fancy ingredients or expensive keto products to eat well.
Here are a few budget keto tips to make every meal count:
- Buy in bulk. Ground beef, chicken thighs, and cheese are cheaper per pound.
- Go frozen. Frozen veggies are just as healthy as fresh and last longer.
- Meal prep weekly. Cook casseroles in batches and freeze portions for quick meals.
- Use what you have. Sub cauliflower for rice, zucchini for noodles, and eggs for protein.
- Avoid waste. Casseroles are great for using up leftovers before they spoil.
And if meal planning still feels overwhelming, the Ultimate Keto Meal Plan can make life so much easier.
