You need to include more info about your one meal, height and your actual weight. If your 5'2 this is alot less interesting

180cm, 75kg, leanish, I optimise for rock climbing and do kettlebell workouts 2 to 3 times a week. I do close to the bare minimum of what is available to stay in decent shape, it takes me less than 4 hours a week total. Not counting the time I save cooking/eating
