deltaG ketone ester has been a game changer for me. Ever since getting heat stroke in 2016, my sweat rate has dramatically increased. This makes fueling for hot races particularly difficult. Being able to fuel with ketone esters allows me to reduce my carbohydrate intake which then allows me to increase the amount of electrolytes I take in without throwing off the osmolity in the gut. This played a huge role in helping me win my 4th North American Ironman Championship in what turned out to be a brutally hot and humid day.
