Eggs contain all nine essential amino acids required for building and repairing muscles, said Pratiksha Kadam, Chief Dietitian at Kokilaben Dhirubhai Ambani Hospital. Consuming three eggs usually provides 18-21 gm protein/day. "Having less than 30gm might not provide enough energy for optimum performance and recovery," said Kadam, adding three eggs aren't enough if they're the only protein source.
