What is a Beef and Butter Fast?
The beef and butter fast is a version of the carnivore diet that focuses exclusively on beef and butter The rules are simple
- Eat only beef and butter
- Season food with only salt
- Drink only water, black coffee or tea
And that’s it! All other foods are off limits, like pork, chicken, fish, vegetables, fruits, nuts, and seeds.
The beef and butter fast is considered a “fast” because it eliminates inflammatory foods that can be difficult to digest like fiber-rich plant foods. However, this is not a fast in the sense of complete calorie restriction. The goal is to get most calories from the beef and use the butter as a supplementary fat source.
Proponents of the beef and butter fast claim it can improve digestion, reduce inflammation, balance hormones, enhance mental clarity, increase energy levels, and spur quick weight loss. However, research is limited and there are potential downsides. We’ll explore the pros and cons later in this article.
Top 7 Benefits of a Beef and Butter Fast
People who have done a short-term beef and butter fast say the following are some of the benefits they experienced:
1. May Improve Digestion
By removing fiber, FODMAPs, and common gut irritants found in plant foods, the beef and butter fast gives your digestive system a chance to rest and reset. This can relieve symptoms like bloating, cramping, and diarrhea in people with IBS or similar conditions.
2. Reduces Inflammation
Eliminating major inflammation-provoking foods like sugar, processed carbs, vegetable oils, dairy, eggs, nuts, seeds, nightshades, and alcohol helps decrease systemic inflammation. This allows the body to devote more energy towards healing.
3. Balances Hormones
Hormones like insulin, cortisol and estrogen can become dysregulated on a modern diet high in carbs and low in nutrients. The beef and butter reset helps optimize hormone balance by stabilizing blood sugar levels.
4. Enhances Mental Clarity
With no carbs to cause blood sugar spikes and crashes, the beef and butter fast puts you in a stable state of ketosis. This provides steady energy and enhanced mental clarity.
5. Increases Energy
Ketone bodies made in the liver are a good source of energy for cells during ketosis. With fewer digestive problems and inflammation, you may have more stable energy levels that don’t drop.
6. Aids Weight Loss
Due to its ultra low-carb, high-protein and high-fat macronutrient ratio, the beef and butter fast may spur quick water weight loss and metabolic shifts that continue fat burning after the fast.
7. Simple and Satisfying
With only two foods to focus on, the beef and butter fast is very simple to follow. It’s also highly satiating thanks to protein and fat, which provide a feeling of fullness.
