Drive-thru diet: Nashville grandpa plans to eat McDonald’s for 100 days in weight-loss attempt
A 57-year-old man from Nashville, Tennessee ate nothing but McDonald's for 100 days in an unconventional attempt to lose weight.
Kevin Maginnis is documenting his journey on his TikTok account @bigmaccoaching.
His plan is to order three meals a day from McDonald's and eat half of each meal – saving the other half for the next meal.

“I woke up this morning and weighed 238 pounds,” Maginnis said in the first video on Feb. 21. “I think that's absolutely unacceptable.”
He added that while many would think he was crazy, he decided to eat nothing but McDonald's fast food for the next 100 days — while practicing portion control.
In another TikTok video, Maginnis shared more about his motivations.
“I'm 57 years old. I have children and grandchildren,” he said.
“I know a few people who are overweight at 60, but I don't know anyone who is overweight at 80. I want to stay here as long as possible, and I think losing some extra pounds will help me do it.”

Ten days into his journey, Maginnis has lost 12-½ pounds, from 238 pounds to 225.5 pounds, he said.
In his video, Maginnis shares his daily order, complete with rhyming puns (“Can eating a McGriddle make you smaller in the middle?”).
Ten days into his journey, Maginnis has lost 12-½ pounds.
His staples include a sausage, egg, and cheese McMuffin with hash browns, McGregor with Canadian bacon, bacon double quarter-pound with cheese, Chicken McNuggets with chips, and McDouble McDouble (all sliced, of course). into two halves).

He even indulged in apple pie and hot fudge sundaes, but opted for water instead of soda.
His experiment at McDonald's garnered national attention — and a growing TikTok following, 20,600 and counting.
Fox News Digital reached out to Maginnis for comment.
As followers watch his journey, people have been offering helpful tips, from creative menu suggestions to the best way to reheat leftovers. (One tip from Maginnis: Use an air fryer instead of a microwave to avoid soggy fries.)
Maginnis also shared videos of him weighing in every day, which has been on a downward trend since he started the new diet plan.

Maginnis said his ultimate goal is to prove that people can lose weight by eating only McDonald's, if they control their portion sizes.
“It's not so much what we eat as it is how much we eat that really lifts us up,” he added.
Drive-Thru Diets Won't Produce Lasting Results, Dietitian Says
Lindsay Allen, MS, RDN, a Florida-based nutritionist specializing in metabolic health and weight loss, has identified several key problems with fast food meal planning.
“Eventually, when they restrict calories for too long, people's metabolisms can drop by as much as 30 percent,” she told Fox News Digital by email.
“Then, when the person starts eating normally again, they immediately regain the weight. This is exactly why fad diets and low-calorie diets fail.”
The second problem, says Allen, is that maginis are missing key nutrients your body needs for optimal health, which can lead to increased food cravings.

“When the brain senses that the body isn't getting enough of key nutrients and minerals, it increases hunger hormones in an attempt to get more of the essential nutrients,” she says.
“If you feed your body only cheap processed food, it will sense this and encourage you to eat more.”

In the end, Allen says, Maginnis is simply practicing calorie restriction to prove that weight loss is possible no matter what you eat. “Technically, he's right, but it's only going to work in the short term and it's going to fail in the end.”
