What Happens to Your Body If You Only Eat Fast Food for 30 Days?

What would really happen to your body if you ate nothing but fast food for 30 days? Not the myths, not the movie version. We follow the actual research: real volunteers, real measurements, week by week. You'll see what a Swedish hospital study found in 18 healthy young adults, what NIH researchers learned from volunteers living on ultra-processed food for 28 days, and why portions, sugary drinks and salt matter so much. If you enjoy science explained with stickmen, subscribe to MrSlinky so you don't miss the next one. This is a science explainer, not medical advice. If you have a health condition, ask your doctor about food.
