IMO more damaging fact is that it doesn't work. The evidence is pretty clear it doesn't actually help you lose weight and in some cases there is actually an increase in weight, obesity, and type-2 diabetes. (https://pubmed.ncbi.nlm.nih.gov/28716847/, https://pubmed.ncbi.nlm.nih.gov/27129676/)

For me this can be pretty easily observed eating a meal with water vs with diet soda. Especially if it's like a 'bad' meal with fast/fried food. There is definitely something that causes you to crave/eat more.
