When it comes to losing weight, there are products that will promise you everything — especially drinks. There are flat-tummy teas, fat-burning drinks and weight-loss smoothies. While your friend Jessica might swear by them, do any of these products actually work?

The short answer: Nope.

“They are not really going to promote long-term weight loss,” Krista Schreiber, a dietitian at University of Pittsburgh Medical Center, told TODAY. “There hasn’t been any evidence-based research for most things that are supposed to detox.”

Schreiber and other experts outlined which drinks you may want to be wary of:

1. Apple cider vinegar

People often drink a shot of apple cider vinegar as part of dietary changes meant to encourage weight loss. Many believe the tart liquid changes gut health and leads to weight loss. While vinegar certainly can be a healthy addition to a diet, the experts recommend holding off on taking shots of it for weight loss.

“There is evidence to suggest that vinegars can inhibit enzymes that break down food and change up how we digest carbohydrates,” Cassie Vanderwall, a nutritionist at University of Wisconsin Health, told TODAY. “(But) I don’t think the evidence is strong enough to recommend it (for weight loss.)”
