Well, you could but it’s probably not a good idea unless you’re not trying to do keto. Keto is HIGH fat, moderate protein, low carb. It is NOT low fat, low carb.
You need calories. If your insulin is low enough (below 14), you can pull around 37 calories from each pound of fat you have per day. If your insulin is high, then you’ll need to use more dietary fat or your metabolism will go down. I never recommend more than a 15% calorie deficit doing Keto Chow unless you’re VERY in-tune with your body and know what you’re doing with months or years of experience doing keto. Water, almond milk, and all the other low-fat and low-calorie stuff out there is exactly that: low fat and low calorie. Keto is all about living off fat.
Embrace the fat. Use heavy cream or avocado oil in your Keto Chow and put butter on your steak.
