Other research in animals undermines the idea that ketones cause weight loss. A study on mice that ate a high fat diet found that raspberry ketones could reduce appetite. However, raspberry ketones did not directly lead to weight loss by causing the body to burn more fat. It is important to note that raspberry ketones have nothing to do with ketosis or the ketogenic diet. In a state of ketosis, the body burns fat for energy rather than glucose. Ketosis is a process that happens in the body.
Taking raspberry ketones will not trigger ketosis or support a keto diet. Learn more about ketosis here. Diets that are very high in fat can cause a condition called nonalcoholic fatty liver disease.

However, the raspberry ketones may have had nothing to do with the observed weight loss.
