Many wonder if you can take metformin on the keto diet for bodybuilding. This question always comes up on bodybuilding forums and for a good reason.

Both Keto and metformin can benefit bodybuilders, especially during a cut or a period where they are trying to lose fat. Can you combine these two prominent weight loss solutions for even faster weight loss?

In the post, we will examine using metformin on Keto from the standpoint of a bodybuilder. Are there benefits to combining these two popular methods?

The Popularity of Keto and Bodybuilding

Bodybuilding has always been a sport that requires much dedication to transform your body. This includes both bulking and cutting at certain times. There are many ways to cut weight, but Keto is becoming increasingly popular.

The Keto diet is a high-fat, low-carb, and moderate-protein diet. It puts the body into a state of ketosis, where you’re essentially burning ketones created from fat for energy instead of sugar. This diet has been shown to increase weight loss at a rapid weight and to improve metabolic health. Both of these are good things for bodybuilders looking to shed weight.

A big benefit of Keto for bodybuilders is losing fat while retaining as much muscle weight as possible. As we all know, muscle mass rules bodybuilding.

You would think that low carbs would impact recovery post-workout, but the healthy fats in the keto diet can promote recovery. Technically Keto is a moderate protein diet, but it still contains enough protein to feed muscles.

The keto diet is an effective way for bodybuilders to cut down in a relatively short amount of time.

The Use of Metformin in Bodybuilding

Bodybuilding is a competitive sport, and these competitors always seek an edge. This includes using medications like metformin that can help to improve the metabolic state.

Metformin is a drug designed to treat type 2 diabetes. A side effect of this is that it has great weight loss properties. Many medications designed to treat diabetes are great for weight loss, including Ozempic and Mounjaro.

Metformin is believed to increase muscle growth, improve insulin sensitivity, and decrease body fat. It increases muscle growth by simulation the insulin-like growth factor (IGF-1), which is critical for muscle growth.

The improvements to insulin sensitivity that are caused by metformin are also beneficial. When you have high insulin levels, you are more likely to store excess glucose as fat. Metformin can help reduce the ability to store sugar as body fat by improving insulin sensitivity. This helps when trying to lose weight also.

Finally, metformin can help to improve athletic performance by enhancing the body’s ability to use oxygen effectively. This can increase endurance and allow bodybuilders to work out harder and longer. This leads to muscle breakdown and, eventually, muscle growth during recovery.

Metformin on the Keto Diet for Bodybuilding

Given all of the benefits of metformin and the keto diet, it makes sense that combining the two would have compounding effects on fat loss, muscle growth, and athletic performance. It is no wonder that so many bodybuilders are wondering if they can combine metformin and Keto.

We know that the effects of both methods work, but we should also consider whether or not it is safe to do Keto and metformin simultaneously.

First, metformin is generally safe for most people, but it can have side effects like stomach and digestive issues. When taking the medication, you can become nauseated, get diarrhea, and have abdominal pain. Keto can also cause some gastrointestinal distress. Though it is rare, combining the two may strain your digestive tract more. This is something to look out for.

Keto and metformin both increase insulin sensitivity. This means that it just may not be necessary to do both simultaneously. However, combining the two can greatly improve insulin sensitivity and reduce the body’s likelihood of storing sugar as body fat.

If you are at risk of hypoglycemia, or low blood sugar, you should monitor your blood sugar levels if it can be hazardous for it to be too low.

TCombiningmetformin and Keto are relatively safe and effective ways to lose weight for bodybuilding.

If you have any pre-existing health conditions, you may want to consider if Keto and metformin are the right combinations for you. Ultimately, the best route would be to work with a healthcare professional to assess the benefits versus the risk.


The keto diet and the diabetes medication metformin are known for having great metabolic health benefits. This includes stimulating fat loss, promoting muscle growth or preserving as much muscle as possible when cutting, and improving athletic performance.

Bodybuilders looking for an edge may want to try Keto and metformin. Generally, combining metformin and Keto is a safe and effective way to cut down.

However, we highly recommend that you work with a doctor before taking any medication or starting a new diet to ensure it is safe. This is especially true in those with pre-existing conditions.

If you want to be even safer, you should monitor glucose levels and liver and kidney function while using Keto and metformin.
