Basically ketogenic diets can have some nice benefits for some people, such as a more steady energy level, improved mental clarity and an improved ability to run a caloric deficit without getting cravings (which can be extremely helpful for weight loss when combined with keto’s other effects).
The carbs in Huel are amongst the best a meal replacement can go with, but due to the benefits keto can have for people, some people want that option.
The lack of any European ketogenic option was why I launched my company offering one last year, but due to brand loyalty and Huel’s reputation, many here would prefer to wait for them to release one so they can achieve the benefits of keto.
