Man loses 58 pounds by eating only McDonald's for 100 days.

A man in Tennessee lost 58.5 pounds in 100 days by eating only McDonald's food, but only half of what he ordered. He also has healthy blood pressure and good cholesterol. However, a dietitian warns that such a fast-food meal plan can lead to a drop in metabolism and missing out on key nutrients. The man plans to start a different 100-day challenge to focus on fitness goals and incorporate cold plunges into his routine.
