It is, however, worth noting that according to the customary convention (Woodyatt, 1921 ; Shaffer, 1921) this diet is not ketogenic since the ratio of ketogenic(FA) to ketolytic (G) aliments is 1.09. Indeed, the content of fat would have to exactly double (324 g daily) to make the diet ketogenic (FA/G>1–5).
Acetoacetate diester did not improve performance37: a different ketone ester to that used by Cox et al (an acetoacetate diester) decreased cycling performance by 2% given before a 50’ cycling race. Reasons for the difference in findings could be: this ketone ester drink was given along with a can of diet cola 30 mins before exercise and caused GI upset in many athletes. Delivering acetoacetate causes the muscle cells to become more ‘oxidised,’ which is a less favourable state for ATP production. Risk of some gastrointestinal upset with all ketone supplements. The dose, tonicity, time taken before competition and overall volume of a ketone drink will affect how easy it is to tolerate. Many athletes take ketone supplements without side effects, however there are differences between individuals, so practice with ketone supplements in training is advisable to ensure they don’t experience any GI side effects in competition. Geoff Woo discussed this study in a blog post.
The secret step in this recipe that takes this carb-free bread from good to great is the separation of the eggs. You’re going to want to separate the yolks and the whites. The reason for this is that we’re going to whip the egg whites until they are fluffy. We’re looking for soft peaks. This will add some volume to the otherwise dense keto bread. Beating the egg whites is the answer to the denseness that comes with making an almond flour bread. I’ve made countless baked goods using almond flour and the main problem I’ve encountered is how dense the finished product is. The fluffy egg whites in unison with the high dosage of baking powder do a good job of getting this loaf nice and fluffy and adding some air pockets into the loaf. This makes for a better tasting bread.
