Those movie stars and models are literally being paid to work out and eat “clean” – usually at levels that the average joe can never meet. Neither are they paying for the meals or the nutritionists, or the trainers or the gym-time; the studios pay for it all, often delivering the food to their stars in order to maintain their workout schedules. Jason Momoa was eating 56 chicken breasts a week in order to play Khal Drogo. Chris Evans, Chris Pratt and Hugh Jackman all were putting in multiple 90+ minute work outs each day to get into shape for the movies. And this is before they set foot in front of the camera; getting ready for filming usually involves intense dehydration to make those muscles and veins pop, pushing diuretics and sweating out the last drops in order to get that perfect look. Even their height is frequently an illusion. Robert Downey Jr. is 5’8″ and Tom Cruise is 5’7″ – they just appear taller on camera by the magic of apple boxes and convenient ditches.
