TikToker Eating Nothing But McDonald's For 100 Days Says He's Losing Weight. 'From French Fries to Fit Guy.'Kevin Maginnis says the fast-food fitness plan proves that it's not what you eat but how much you eat.

Last month, Kevin Maginnis went on his TikTok channel@bigmaccoachingto try a weirdweight-lossexperiment.

"I'm going to eat nothing butMcDonald'sfor the next 100 days, the 56-year-old Nashville native said, "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."

Maginnis started his unconventional weight-loss plan weighing 238 pounds. He has chronicled every day of his diet on TikTok, eating three meals daily, but only half of the meal.

If you think all Maginnis is only eating salads and yogurt parfait, you'd be wrong. He's eating from the full menu, including Egg McMuffins, Fries, and Big Macs. The only rules are to eat half, only drink water (so soda or juice), and no snacks in between.

Some TikTok users expressed concern about food waste, but Maginnis assured them he was saving each un-eaten meal and eating it the next day.

Is the diet working?

Maginnis claims to have lost 12.5 pounds in 10 days. Yesterday, he went on theToday Showto discuss his journey, saying he estimated dropping 50 pounds in 100 days.

"My health will be better. My blood work will be better," he said. "And if you don't believe me, follow along. Let's find out."

Maginnis isn't the first to try this experiment. In 2014, ahigh school biology teacherJohn Cisna only ate only McDonald's for 90 days, asking his students to design his menu. By the end of 3 months, he'd lost 37 pounds.

But most nutritionists and doctors do not recommend Mcdonald's for three meals a day. Sure, you may lose weight, but other health issues must be considered, including the detrimental effects of diets high in sugar, sodium, and fat.

"One of the most immediate effects of eating at McDonald's is feeling extremely tired and groggy after your meal," saidBansari Acharya RDN, a registered dietitian nutritionist toldEat This, Not That. "Your body feels like it has low energy due to it trying to digest the overload of fat and sugar."
