  1. Think of all the DEAD Hollywood Stars that have taken Weight Loss Pills and their Birth Defect affect Children. The 1950s were a “Wonderful time” for Diet Pills and now the Children are really suffering the results. Now our children have the Ultimate Diet of a Whole Food, Plant Based Diet.

  2. i took alli before. it’s no joke. an orange oil will legit leak out of your butthole and it has the strongest stench of literal shit. if you get it on anything (including your hands) it will also smell like shit. needless to say i stopped taking it.

  3. It really all boils down to calories consumed vs calories burned, nobody will gain weight if they consume less calories than they burn off. simple as that. but people want to be able to eat that whopper, with large fries, and snack with junk food anytime they get the urge, and fix it with a pill. don’t talk to me about slow metabolism, rule still applies, I have a slow metabolism, if I limit carbs in my diet, and keep total calories below 1500 a day, I lose weight. 1500 calories is what some people have for lunch.

    as for diet supplements, the only one that I know really worked, was the ECA stack. ( Ephedra Caffeine, Aspirin ) popular in the 90’s. but a few abuses by people and negative media coverage, got them removed, just in time for big pharma’s Phen fen. fiasco.
