I enjoy talking about weight loss and what works and with apologies since I did not see this thread with the first post unedited and feel more was said that I can't respond to because it's not there
I'd just like to comment that what has worked for me is eating less and moving more and logging calories and other nutrients so I can get a handle on what I am eating.
Re green tea, I think it's an energizing drink and probably has some health benefits but as far as weight loss goes, it seems to my uneducated brain that maybe it's tea's action as a diuretic that accounts for some of the general feeling that tea helps people lose weight.
Regarding bitter orange, Suzanne said it all. Seems to be dangerous.
I think increased fiber intake helps general health and for me it seems to help in blood sugar regulation by reducing the glycemic response of food (or something, I'm not a doctor, just know that fiber helps me feel better and manage appetite, as does protein ratio in food).
Re the supplement industry as it relates to pills for weight loss (as opposed to, say, whey or soy protein powders, which are supplements but also foods), I personally think it's pretty much all bunk and to me it's scary how many diet pills there are out there with people madly ingesting them without really knowing what's in them (the labels can be telling the truth or they can be lying, how is the average consumer to know that).
Even IF (and it's a big if) some of these pills aid in weight loss, I personally would not take a chance.
I've not always been that way and years ago did experiment now and then with products including ephedra until I became aware it was killing folks. Nowadays, I just don't think weight control is worth the risk and that there are no magic pills except the pills in our own head and hearts of just toughing it out, making the lifestyle changes we KNOW work and won't kill us (on the contrary, they might add years to our lives).
Sorry, ranting. It's been a long day.
