The answer is more interesting than simply “you lose weight.”

First, Understand What “No Sugar” Really Means

A 30-day no-sugar challenge should not necessarily mean avoiding fruit, vegetables, or plain dairy products.

Instead, focus on reducing added sugars.

That includes sugar added to:

• Regular soda
• Sweetened tea and coffee
• Energy drinks
• Cakes and pastries
• Candy
• Ice cream
• Sweetened cereals
• Flavored yogurts
• Sweetened sauces
• Many packaged snacks

The CDC notes that sugary drinks are a major source of added sugar and that frequent consumption is associated with weight gain, obesity, type 2 diabetes, heart disease, cavities, and gout.

That makes beverages one of the easiest places to start.
