A CEO who has been running a company generating sales in the tens of billions of won and has not changed his diet for over 20 years is drawing attention.
According to recent reports from Business Insider and The Mirror, Luke Carlson (46), the head of the fitness company Discover Strength, which records annual sales of about $37 million (approximately 5.45 billion won), has maintained the same diet for 22 years.
For breakfast, he mixes oatmeal with banana, protein powder, and creatine, and adds a protein bar. For lunch, he has a chicken or turkey sandwich with an apple and a protein shake. For dinner, he chooses from chicken, steak, or salmon. His total daily caloric intake is consistently kept between 1,900 and 2,200 kcal.

The chicken and turkey included in his lunch are low in fat and high in protein, making them advantageous for weight management. Whole grain bread helps prevent sharp spikes in blood sugar, and apples help moderate post-meal blood glucose increases by providing dietary fiber. Salmon, featured in his dinner options, is rich in omega-3 fatty acids, which support cardiovascular health, while steak serves as a source of iron and vitamin B12.
Carlson emphasized, "The lunch sandwich is a rule that never changes for me," adding, "Thanks to this routine, I can dedicate my creativity and focus to my business." He also stated, "The biggest advantage is not having to worry about what to eat," explaining, "Rather than constantly planning my meals for 10 or 20 years from now, I focus on the nutrients and calories I need right now."
He has also simplified his wardrobe, repeatedly wearing pants and tops from a particular brand along with white shoes, minimizing daily decisions. This is a lifestyle aimed at reducing what is known as 'decision fatigue.'
However, experts point out that maintaining the same diet for long periods could potentially lead to deficiencies in certain vitamins or minerals, and the monotony of such meals could also act as a source of stress.
