Much has been reported in sports media as well as to a lesser degree in the general media of cyclists taking ketone esters or ketone salts to enhance their performance during the Tour de France cycling competition. At least six teams admitted to consuming the supplement for performance or recovery enhancement during the 2019 tour. But what about your average person, how does it affect them?

I will report my anecdotal findings soon – stay tuned – and compare them to what the science is suggesting as well as what the cyclists have found. This is based on using exclusively a product called KetoneAid, makers of a ketone ester (beverage).

At this time, apparently, scientific findings are much more conclusive when testing the ester than the salt.

Athlete profile: 

Age: 53
Gender: Male
Sport: Road and trail distance running
Fitness: Modest
Height: 5’9″
Weight: 147-149 lbs


Ten years off from semi-competitive masters-age long-distance running, primarily road. During that break, there were three surgeries: 2 x Haglund’s Deformity (each heel, 2009, 2010), 1 x hip replacement (right) in late 2016. Back running from April 2017 on a very low volume program with a gradual increase over the latest two-plus years.

During 2018, I was on a disciplined ketogenic diet. Results were typical with rapid weight loss, and modest gain after three months. Experienced apparent untappable endurance (7-hour road cycle with almost no prior adaptation) while also suffering from debilitating anaerobic-like efforts over shorter, faster and especially steep hill work on foot. Currently, eating a low-carb – high-fat diet (almost 0 refined carbs – carbs obtained through whole foods).

Currently running 60-70 kilometres per week. Two gym sessions of various upper-body weight exercises and heavy bag exercise per week. Some modest road cycling. Active lifestyle. Walks 10-30K per week.

Product: KetoneAid (ester).

Preliminary anecdotal note: Apparent improved post-run recovery, allowing a greater weekly mileage volume increase.

Stay tuned.
