HEALTH;This Diet Is All Over Reddit—But Here’s What It Gets Wrong

Take a deep-dive into the weight-loss forums on Reddit and you're bound to come across the CICO diet.

One user who had been following CICO for two months and shed 20 pounds wrote, "For years I actually thought that [losing weight] required vigorous exercise, and eating nothing but tilapia, broccoli, and spinach. How wrong I was."

In a separate thread, another user shared, "CICO will work regardless of what you're eating. Junk food, healthy food, fancy food, cheap food. It doesn't matter. CICO is essentially the only thing that matters when it comes to weight loss."
But many experts have a different take on the eating strategy, and argue that CICO is just another name for a weight-loss myth that refuses to die.
