John Krasinski’s Diet
Krasinski admits his real life was a little too much like his Office character Jim’s, downing whatever from an all-you-can-eat buffet, and he is the first one to admit he didn’t 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.
- Low Carbs 20% 20%
- Low Fat 15% 15%
- High Protein 80% 80%
Eat Like a SEAL
The marine mammal may have a more varied diet than Krasinski while he was training for the role of soldier. He says his diet was very limited, and consisted primarily of chicken breast and salad.
Hydration is Key
Krasinski drank tons of water to keep him hydrated during his intense workout sessions, and to help fill him up on his restricted diet.
Krasinski first thought to gain weight by gorging himself on Mexican food, thinking it would ‘automatically’ convert to muscle. He admits he didn’t really know what he was doing.
Krasinski’s trainer not only chose the foods he would eat, but also when he would eat them, such as refueling with carbs and protein after exercising to help grow muscle.
