Long-term nutritional ketosis improves metabolism and reduces inflammatory markers in women.
Nutritional ketosis is a powerful tool for managing weight and moderating inflammation. However, most studies on ketosis have been conducted in men and have only assessed short-term effects. A recent study found that nutritional ketosis reduces blood glucose, insulin, and inflammatory markers in healthy women practicing long-term ketosis.
Researchers asked ten healthy young women who had been maintaining nutritional ketosis for more than a year to alter their dietary habits to suppress ketosis. The study involved three one-week phases: nutritional ketosis, suppressed ketosis, and return to nutritional ketosis. The researchers measured the women’s ketone levels daily; at the end of each phase, they took their women’s body measurements and assessed their metabolic and inflammatory biomarkers.

They found that when the women suppressed ketosis, their insulin, IGF-1, glucose, and pro-inflammatory markers increased. However, when they returned to ketosis, those markers returned to baseline levels.
These findings suggest that nutritional ketosis maintains healthy metabolism and suppresses inflammation without altering metabolic flexibility. Other evidence demonstrates that a ketogenic diet promotes weight loss and reduces cancer risk. Learn how to design the optimal ketogenic diet in this episode featuring Dr. Dominic D'Agostino
