A Nashville grandfather has recently revealed his whopping weight loss from a 100-day McDonald’s diet. Kevin Maginnis ate only McDonald’s for 100 days straight – breakfast, lunch, and dinner – and boasted about his massive weight loss on the final day of the unusual diet that began earlier this year. He went from 238 pounds to 179.5 pounds – a whopping 58.5 pound difference – by sticking with the fast food joint’s fries and burgers.

Maginnis became a viral sensation when he began to document his journey to lose weight on Feb. 21. Part of his secret to success was eating only half the provided food in each meal and sticking to water rather than soda. He also didn’t consume alcohol or munch on snacks during the 100 days.

Maginnis urged others to “stop vilifying the food” and focus on the portions. “Are there better micronutrients or macronutrients for brain health? Absolutely. But when it comes to getting rid of obesity, reduce the size of the meals,” he said.

Maginnis claimed his blood work has also improved, noting his triglycerides are down 205 points and cholesterol 65 points lower. “Can eating a quarter pounder with cheese improve my A1C?” he told Today hosts. “Looks like it can because I was pre-diabetic before, down into healthy ranges now.”

The diet has become such a success that even his wife started her own only-McDonalds diet on day 40 of his 100 days, according to a Thursday interview he did with Fox News. As of day 65, she has shed 18 pounds.

This story is an interesting example of how portion control can play a significant role in weight loss, even when consuming fast food. However, it is important to note that this is just one person’s experience and it is not necessarily advisable to follow their exact diet plan. It is always best to speak to a doctor or registered dietitian before making any major changes to your diet.

Here are some additional details about Maginnis’s diet:

  • He ate a variety of McDonald’s items, including burgers, fries, chicken nuggets, and salads.
  • He avoided sugary drinks and alcohol.
  • He drank plenty of water.
  • He did not exercise during the 100 days.

Maginnis’s results are impressive, but it is important to remember that everyone’s body is different. What works for one person may not work for another. If you are considering trying a similar diet, it is important to talk to your doctor first. They can help you create a safe and effective plan that is right for you.
