Limit your carbs to 25g net carbs – typically everyone reaches ketosis below 20g. Many are able to reach and stay in ketosis at 50 gms so be sure to test.

Eat all your protein which is typically about 0.6 gms per pound of body weight for those who are not super physically active.

Eat Fat as a lever and only if you are hungry. You do NOT need to eat all the fat.

¿Do I Really Need To Count Macros?

A lot of people count nothing but carbs. They limit their carbs, and other than that, they just eat protein and fat when they’re hungry.

This works for many people. Many experts have stated that what works best for many is to start by counting everything rigorously. However, over time, as you become more familiar with all the hidden sources of carbohydrates, you can stop being a super fan of tracking if you prefer not to.

At that point, you can only keep track of carbs.

So do what works for you!
