John Krasinski’s Diet
Summary
Krasinski admits his real life was a little too much like his Office character Jimโs, downing whatever from an all-you-can-eat buffet, and he is the first one to admit he didnโt know much about nutrition before he began training for 13 Hours. He reduced his body fat from about 25% to 9% in just 4 months by working closely with a trainer who had him on a strict diet and exercise routine. His staples were lean animal protein, leafy, low-carb veggies and plenty of water, but he was allowed to have some carbs after his grueling workouts, along with protein.
Estimated Macros
- Low Carbs 20%
