Does diet root beer help you lose weight?

WHO’s 2023 guideline recommends against using non-sugar sweeteners (NSS) to control body weight or reduce the risk of noncommunicable diseases. It states that replacing free sugars with NSS does not help with weight control in the long term. WHO calls the recommendation conditional. It applies to all people except those with pre-existing diabetes. WHO lists acesulfame K, aspartame, advantame, cyclamates, neotame, saccharin, sucralose and stevia products as common NSS. Check your can’s ingredient list to see which one it uses.

Is diet or zero sugar root beer bad for you?

WHO says its review suggests potential undesirable effects from long-term NSS use, such as an increased risk of type 2 diabetes, and also lists cardiovascular diseases and mortality in adults. The page adds that the links might be confounded by baseline characteristics of study participants. If you have diabetes or a health condition, ask a doctor or pharmacist.

How does it compare with regular root beer?

USDA’s generic regular root beer entry lists 41 kcal, 10.6 g carbohydrate and 13 mg sodium per 100 g. We found no USDA entry for diet root beer, so read the nutrition label on the product for its calories.

Does root beer have phosphorus?

USDA’s generic root beer entry lists 0 mg phosphorus per 100 g. That is a generic product, not A&W or any brand, and we found no brand data. Check the label.
