alt Hacker NewsI'm in the US and have a large friend circle across multiple states (from having moved for work over the years) and also do not know one single person using them. However my friends tend to be quite active.
The Added Sugars (that's how they are listed on labels in the US) are _insanely_ and insidiously pervasive in US food. it's truly nefarious.
A close family member and myself are both on them. They get very upset if I ever mention them using them while I happily tell anyone about myself. Wanting to lose weight is shameful to many.
Wait for swimsuit season and I have a feeling your even active friends might start without telling anyone.
