I'm new, 75 lbs to lose...
Please give me all advices possible.
Plan:
1. colon cleansing
2. Sports
3. Diet Pills

I'm not counting on the pills, but it's a part of my plan.
Docotor already prescribed for Xenical, but it's too expensive
I taught maybe to try Generic Xenical pills or try Herbal Xenical.
Please comment and give advices.

Ditch the plan.

Eat healthy foods in reasonable amounts (fruit and veg, lean proteins, whole grains, and healthy fats like olive oil).

Get some exercise.

That's really all you need. Colon cleanses are useless for losing weight and your colon doesn't need "cleansing" anyway. Diet pills are pretty much just a scam. At best you'll suppress your appetite for a bit and at worst you'll damage your body.

Agreed. Skip the pills and colon cleansers.

I'll tell you what worked for me, not recommending it, just saying what I did...

Atkins style extreme low carb. I know, it's not a popular thing to say, but it knocked 50 or so lbs off in 4-5 months. If I had the discipline to just eat healthy, I probably could have done the same thing, but I don't. I found that for me, eating fats and protein worked.

Now, I eat a healthy low glycemic impact diet, but I needed something to jump start my weight loss. I also exercise at least 5 times a week.

If you want appetite suppression + clean energy I would use Slim Xtreme. Works excellent and is herbal.
