“Eating smaller portions at short intervals throughout the day helps you continue to burn fat and maintain higher overall energy,” says Page Love, a sports nutrition expert and former NCAA tennis player at Baylor University who has served as on-site dietitian for WTA events.

“Many pros carry energy bars, gels and sports drinks, all of which contain various compositions of carbs, proteins and electrolytes. As a tennis player, you need snacks before and after play to keep energy levels high on the court, and particularly during strenuous training sessions, so take advantage of some of these portable food choices.

Choose snacks from grains and fruits, combined with protein sources like nuts and low-fat cheese.”
