Harry is also said to have lost 10lbs since he and Meghan announced their engagement in December, thanks to workouts at the exclusive KX private members health club in Chelsea where membership costs £575 a month.
The royal has been spotted there at 7am on an almost daily basis, ''getting his soldier body back''.
Meghan herself loves to keep fit and goes jogging to clear her head, as well as keeping up her yoga.
And it seems she's also keen for Harry to share her healthy eating practices as he's reportedly been working with Gabriela Peacock, the nutritional therapist at exclusive women's club Grace Belgravia where Meghan is a member.
While the Prince is known for his love of KFC and Haribo, Meghan takes a rather healthier approach.
She previously told Good Housekeeping that her fridge staples are hummus, carrots, green juice, almond milk and chia seed pudding.
