Could

a special diet boost your partner’s testosterone levels? That’s the finding of a new study on ketogenic diets, which are high in fat and low in carbs. The study, which involved 230 participants following a keto diet, resulted in a significant testosterone increase. Men who reduced their calorie intake experienced the greatest rise in testosterone levels. In fact, a keto diet could make your other half more cheerful, too, since keto dieters often report an increase in energy and wellbeing. But remember, seek medical advice before trying a diet.
