Maintaining optimal protein intake is crucial on a keto diet, but consuming too much protein can undermine its benefits. While protein supports muscle retention and satiety, excessive amounts—especially from animal sources—may disrupt ketosis by raising blood glucose via gluconeogenesis. This shift can slow fat loss and impair metabolic flexibility. Most experts recommend keeping daily protein at 0.6 to 1 gram per pound of lean body mass, avoiding overconsumption beyond this range. Monitoring ketone levels, adjusting protein sources like prioritizing fatty fish and eggs over processed meats, and focusing on whole-food options helps preserve ketosis while supporting overall health. Always tailor intake to individual activity levels and health goals for sustainable success on keto.
