Strongman Mateusz Kieliszkowski Eats Way Fewer Calories Than You Think

“The Polish Terminator” hits his bulking targets with meats and sweets.

Polish Strongman Mateusz Kieliszkowski has been in recovery from an Achilles tendon injury after placing second at the 2024 Arnold Strongman Classic in March. Since mending, he’s training for his next yet-to-be-announced contest.

On Oct. 15, 2024, Kieliszkowski posted his full diet and supplement regimen for intense training for three Strongman exercises: Keg Toss, Sled Push with 150 kilograms, and Atlas Stones.

Supplement Stack

Kieliszkowski doesn’t go overboard with supplements, instead sticking to basics:

Kieliszkowski adds Celtic salt to his water and drinks isotonic sports drinks combined with caffeine and creatine to stay hydrated.

Breakfast — 830 Calories 

Starting the day with a healthy, balanced breakfast helps control Kieliszkowski’s blood sugar. He eats six eggs, cutting back from a dozen a day, “I got sick of it,” he admits, concocting a scrambled omelet with meat pieces and homegrown veggies. His full breakfast comprises:

  • Six eggs
  • Bread roll 
  • Meat pieces 
  • Vegetables
  • Coffee

A few hours later, Kieliszkowski indulges in desserts.

Protein Shake & Donuts — 1,300 Calories

One of the perks of being a pro Strongman is the freedom to eat cheat foods often. For Kieliszkowski, that means indulging in donuts and yeast buns.

Donuts are my weakness; I eat them quite often. I’m not a bodybuilder. I won’t be rigorous in approaching my food.

Kieliszkowski washes down the donits with a protein shake blended with nut butter and whole nuts:

  • 50 grams of protein isolate powder with milk
  • Large spoonful of pistachio butter
  • Macadamia nuts

Before, Post Training & Dinner — 2,660 Calories

Kieliszkowski crams in a few hundred more calories via grilled chicken and rice before training. Immediately after his workout, he downs a fast-digesting recovery shake and grills his last two meals: juicy beef steaks, potatoes, and 350 grams of beef burger loaded with cheese and condiments, including salt, pepper, and barbecue sauce. Excluding the protein shake, that amounts to 2,660 calories. 

Overall, Kieliszkowski consumed 4,790 calories for the day, which is not nearly what as many as one might expect for a strongman of his stature competing at the highest level.
