A Nashville man, Kevin Maginnis, is eating only McDonalds for 100 days to lose weight and says it’s “Absolutely working”

Nashville grandpa Kevin Maginnis, 56, is ready to defy all odds by eating McDonald’s for 100 consecutive days in an effort to drop some excess weight — and it’s already working.

I woke up this morning and I weighed 238 pounds,” Maginnis shared on his TikTok page @bigmaccoaching on Feb. 21. “I decided that that is absolutely unacceptable.”

Maginnis, whose TikTok has been viewed over 650k times, believes that weight gain is attributed to not what you’re eating but how much food a person is consuming.

While on his bizarre dieting journey, Maginnis ruled out snacking and will only eat half of his order per meal, saving the other half for his next meal with water being his drink of choice.

By Day two, Maginnis said he was feeling “heat” in his stomach from cutting down his calorie intake.

On Day three, Maginnis shared that he was down three pounds and revealed he had blood work done to see how his diet was affecting his health, aside from weight loss.

His blood work showed his A1C (blood sugar levels) was “not good” with the rest of the results being “okay,” but Maginnis believes the more weight he shreds, the better his numbers will be the next time around.

In late February, the Nashville native, 56, began documenting his journey using the mantra "French fries to fit guy." In his first video on TikTok, which garnered over 500,000 views, he shared his starting weight of 238 pounds and outlined his plan.

"I'm going to eat nothing but McDonald's for the next 100 days, but instead of eating everything they give me, I'm going to go ahead and cut the meals in half just to prove to myself and maybe some of the other people watching that it's not as much what you're eating, it's the quantity that we're eating that really jacks us up," he said.

He got some questions about food waste from followers, but assured them that he saves the other half of the meal to heat up the next time he eats. As Thursday marked day 10 of his diet, Maginnis appeared on the Today Show to give Carson Daly and Sheinelle Jones an update on his progress and how it's "absolutely working."

"This morning, I was twelve and a half pounds down — start of day 10," he said.

When Jones asked if he's talked to a doctor about his new habits, Maginnis shared what experts have told him.A Nashville man is eating only McDonalds for 100 days to lose weight and says it’s “Absolutely working”
