One of the biggest myths about keto? That it’s expensive. The truth is: keto can be incredibly affordable when you know what to stock up on. By focusing on simple, whole ingredients that offer versatility, satiety, and nutrition—you can stretch your dollar and stay in ketosis.

This guide breaks down 10 must-have keto ingredients that are cheap, easy to find, and meal-prep friendly.

1. Eggs – The Ultimate Keto MVP

2. Canned Tuna or Sardines

Why they’re great: High in protein and healthy fats. Long shelf life.

Ideas:
