Fat Fast Foods | What to Eat and What to Avoid

While following a fat fast diet, it's important to eat the proper foods and also avoid certain groups of foods in order to be successful. 

If you're looking to lose weight while starting a low-carb, high-fat diet like keto, a fat fast will aid in your journey. For a short period of time (typically 2-5 days), you'll be eating a very restrictive low-calorie diet comprised of predominantly foods that are high in fat and low in carbs.

Salmon, oil, and nuts are all allowed while on a fat fast diet.

Because of its extremely restrictive nature, this diet is recommended for only short periods of time and is not recommended for longterm. To learn more about a fat fast diet, check out our blog post. 

Foods You Can Eat on a Fat Fast

Since fat is an essential component while on a fat fast, you'll want to consume predominantly fat. The following foods are permitted on the fat fast diet. 

  • Butter
  • Oil
  • Avocado
  • High-Fat Dairy 
  • Nuts
  • Nut Butters
  • Fatty Fish like Salmon and Tuna
  • Leafy Greens
  • Broccoli

  • Non-Starchy Vegetables

Not only do you want to follow a high-fat diet, but you'll also want to eat some proteins in smaller amounts. Be sure to make sure your protein intake doesn't exceed for fat intake. 

Foods to Avoid on a Fat Fast

What is a Fat Fast? 

A fat fast diet focuses on a calorie deficit where 80-90% of calories come from only fat. In its simplest form, it's an accelerated version of a keto diet because it helps burn fat stores. 

A Fat Fast Diet Consists of High-Fat Foods

Whether you're starting a low-carb, high-fat diet like keto or you want to get into ketosis fast, you may use fat fasting as a tool to achieve ketosis. Because this type of diet is considered very restrictive, it's typically recommended to last only a few days. 

Bottom Line

If you're looking to be successful on a fat fast diet, you'll want to consume high fat foods and avoid carbohydrates and sugars.
