Nikolaos Tsokanos Keto Summit 2019:

Some people are now saying that keto causes bone loss. Is it true?

A study saying that keto causes bone loss is concerning some people. So today, let’s take a deeper look at that study. 

A few red flags about this study:

• The study was done on 30 world-class professional athletes. 

• The study was only done for three weeks. 

• The study didn’t include what they ate. 

Professional athletes are usually carb-burning machines. They’re used to carbs, and if they’re going to try to adapt to the keto diet, it’s going to take more than three weeks. However, once adapted, their bodies can potentially burn 3x more fat than other people. 

The study also showed impaired bone modeling and remodeling. But, it didn’t show a loss of bone mineral density or strength. The impaired bone modeling and remodeling don’t actually mean osteoporosis or osteopenia. 

We also don’t even know exactly what the diet was that these people were consuming. Was it really keto? Was it dirty keto? Did they have enough vitamin K2 (which helps build bone)? Did they have enough vitamin D3, calcium, or vitamin C? We don’t know. 

To build bone, I believe you need the combination of those vitamins and minerals, and you would also need to keep your stress low and your hormones in check. 

Another long-term study performed on menopausal women indicated no effect on bone. Be sure to read studies thoroughly before jumping to any conclusions.
