Any product associated with the words “keto” and “performance” is bound to turn gym bros’ heads, especially when Nasa is investigating whether it could be used to fuel astronauts travelling to Mars. Until recently, it was thought that the only way to get a high level of ketones – the slow-burning fuel source that promises near-limitless endurance – was to adhere strictly to the zero-carb keto diet. As fuel, ketones are hyper-efficient: they produce more ATP molecules (which help to fuel muscles) than glucose, and no lactic acid.
The problem is that arriving at and acclimatising to ketosis through food can take weeks. As a result, scientists have recently been attempting to synthesise ketones as a supplement. Mostly, they’ve failed.
Now, the energy drink HVMN Ketone aims to provide the solution. As with any new science, however, the research remains fledgling. According to a study published in the journal Cell Metabolism, elite cyclists rode an average of 2 per cent further over 30 minutes when they consumed the drink. Amateurs may consider the improvement insignificant, but it could mean the difference between silver and gold for Olympians.
The results are promising. If you’re an endurance athlete, watch this space. If you’re a recreational runner, though, think long and hard whether you can spare £25 for a single serving.
