CKD works for many athletes and bodybuilders but it’s not typically suggested for those looking to lose weight or those with a poor relationship with food. Some members have done this to lose weight but it would very likely be much slower because you’re only in ketosis for 2-3 days a week. For myself, I would rather be a fat burning machine all of the time, not just a few days a week. It all depends on how you want to go about your journey and what your goals are.
For me, after one meal with carbs my stomach is killing me. After 2 days I can feel the brain fog. That leads to poor choices and suddenly it’s 4 or 5 days, my joints are achy again, and I don’t sleep as well. Not worth it to get out of keto for a meal.
For myself personally once I became fat adapted that changed everything for me. My cardio is insane now and it’s been easy to build muscle even with the moderate amounts of protein I am eating. A friend of mine is a track coach and this was his opinion on this. Cyclical keto is for athletes competing in endurance events such as marathons, triathlons, and cycling. It is NOT for individuals trying to lose weight. Many people that exercise are not waiting sufficient time to get fat adapted and that is the appeal of cyclical keto. As we have talked once I became fat adapted there were no issues running and cycling. The ectomorph types possibly? Anyone else no in my opinion.
