I guess I'll weigh in now since I said I would.
I was a fat kid. There's no way around that. I want to find an old picture of me when I was in 8th or 9th grade. I'll hunt one down at some point...Just for argument sake, I was 240 pounds in 9th grade. That's what, 14 years old? I as BIG.
My after school snacks were a package of poptarts and a twinkie or a 1/3 of a package of Oreos or a half-bag of chips. This was always accompanied by a soda. It was bad and I knew it...I was actually sneaking food into the basement to eat before dinner.
My mother was doing Herbalife sometime during my freshman year of HS. I approached her and said I wanted to try it because I wanted to lose weight. She was on it because she must have thought she was overweight (she wasn't). But she agreed to let me try it after she had been on it for a few months to make sure it wasn't terrible for you.
Well, months later, I actually DID loose a LOT of weight - I was down to ~140 pounds. My breakfasts were these breakfast bars (they remind me of Quest bars in texture) that she made using the shake powder they give you mixed with oatmeal and peanut butter and milk? I don't remember, but they were actually really good. My lunch was usually a sandwich, some fruit, a bottle of water, and a small one of those breakfast bars for dessert (it was sweet and I love sweets). Dinner was a meal shake.
Anyways, I don't know if Herbalife actually WORKS, but at the time, it did for me. When I was on it, they were still using ephedra. So...But there were a LOT of pills that you took. I'm not even sure what they all were, but I took like 5 or 6 with each meal. I also didn't really change my activity habits during the time I was on it.
However!
Mentally, I was approaching my eating habits a LOT differently. I went from way too many carbs, calories, and grams of fat a day to SIGNIFICANTLY less. So part of me says the system was a sham and only put me in a mental state to eat less and stick with it. I mean hell, a month before my honey moon, I cut down my carb intake to like, 20g a day and lost like 15 pounds without even trying (I ate low carb tortillas, lots of nuts, salads, chicken, steak, and bacon). So it's clear that I can loose weight by cutting out sugars and carbs, but I think we already knew that.
So that's how I take it. I don't like the company and don't agree with the whole MLM/pyramid scheme thing. I think it's shit and completely terrible for folks who are easily sucked into it. Having said that, the product (of the late 90's early 2000's) DID change my life. I would never do it again nor ask anyone to do it today, though...I think there are cheaper, better, and safer ways to loose weight than taking a bunch of pills that may or may not be doing anything.
And I've already text my mother to see if she can't scan me a pic of me in 8th/9th grade so I can show how different I looked, ha.
Don't you think your drastic change in diet influenced your weight loss? As far as the nutritional bars, the point is that you could have accomplished the same thing with another (likelier cheaper) set of bars. EDIT: I see you mostly addressed these points, but it's still a leap to credit the change in your life to the product in and of itself. You more or less concede that implicitly even while explicitly saying it changed your life.
