TikToker ate just McDonald’s for 100 days — and lost 58 pounds

A Tennessee TikToker stepped on the scale and didn’t like the number that popped up, so he decided to make a lifestyle change.

But Kevin Maginnis, 57, of Nashville didn’t join a gym and start meal prepping — instead, he drove to the clos- est McDonald’s.

On Feb. 21, Maginnis, known as @bigmaccoach- ing on TikTok, said on the social media site weighing 238 pounds was “absolutely unacceptable.”

Maginnis said that although he knows people are going to think he’s crazy, he planned to eat only McDonald’s for the next 100 days, according to the Feb. 22 TikTok that’s garnered more than 2.4 million views.

By April 20, Maginnis was 59 days in and 41 pounds down, according to his Tik- Tok.

“Guys, is it possible for chicken, eggs and bacon to be taking the excess weight off my body?” he asked in the video while enjoying a McGriddle.

On June 1, Day 100 of his journey, Maginnis posted a TikTok of his final weigh-in, showing his followers he had lost 58.5 pounds.

Although the McDonald’s diet seemed to have worked for Maginnis, experts are skeptical of this approach.

“Is a calorie a calorie when it comes to weight loss? Tech- nically, yes. That’s what is going to work in this situation,” Tara Schmidt, lead registered dietitian for the New Mayo Clinic Diet, said to Fortune Well. “The topics that have not yet been addressed, though, are nutri
