For Weight Loss (Obesity/Overweight) "I have tried diet after diet. I was weighing a size 20. Within 2 1/2 months, I am proud to say I am in a size 14! I have been an example for those same individuals who had negative thoughts about Alli, now they're running to the stores to purchase it as well. I must say I had to do my part as well. I now know how to eat and what to eat. Although, should I have a craving, I eat a very small portion to satisfy me, that's it! Thanks."

For Weight Loss (Obesity/Overweight) "The new generation of Orlistat, sold over the counter as Alli, does NOT work. I was on Xenical when it first came out in the 1990's. It worked very well and the orange discharge was a daily thing. Now 4 months ago I purchased Alli over the counter. Paid $85 and was very disappointed to find out that I had wasted my money. First, each pill is filled only 60mg instead of the Xenical which is 120mg so it is not the same dose. Second, even when doubling up doses it still does not grab the fat and produce the orange discharge like the old ones used to. I will never purchase this again. It is basically a placebo. I tried the keto diet for awhile to help with weight loss but the constipation & limitations were so horrible it didn't work. Also tried Phentermine and it too was unsuccessful in the long run. What works? The MY PLATE model, using a toddler sized sectioned plate."

For Weight Loss (Obesity/Overweight) "I have been using Alli for a month. I take it three times a day along with exercise about 3 days a week by walking and running. I started out weighing 222 and now I am down to 215 and shrinking. IT WORKS!! I have tried so many weigh loss pills and this is the only one I have used that actually works. At first it worried me to see the oil substance in my stool but I quickly learned it was my body fat residue leaving my body. I feel great and I will continue using the product. My advice is not to rely on any product to loose weight. Use the product but get off your lazy butt and exercise and eat right and by doing so with this product you will achieve results."

For Weight Loss (Obesity/Overweight) "In the past I used the prescription strength orlistat 120mg and I lost 45-50 pounds, short term, I also used portion control, exercised daily and felt the side affects if I ate something I shouldn't have. Years later Alli was on the shelf after I went to the Dr in need of help to lose the pesky 10-20 pounds and my Dr told me to use alli but double the dose and it is equivalent to prescription strength. So far I am down 6 pounds in 1 1/2 weeks. Alli is only a temporary kickstart to any weight loss plan and is not intended for long term use. It has worked for me. The right way is to get up and move and know your portions and drink plenty of water!!"

For Weight Loss (Obesity/Overweight) "I have lost 27 pounds on Alli over a five-month period. Mainly, it's aversion therapy. Nobody wants side effects, so you make common sense meal choices. Best success I have ever seen with any diet. I went from 137 to 110!!! I have also never had any extra side effects, like some have mentioned. Highly recommend!!"

For Weight Loss (Obesity/Overweight) "I started using this on 02/20/14 and use everyday (as directed) and have not had one "side effect". Changed my eating habits and doing Jillian Michaels 30 Day Shred and am down from 201lbs to 195lbs today. I don't know if it the Alli, the workout, or eating different but something is working and without any side effects. I would definitely recommend and hopefully it will get these other 45lbs off."

For Weight Loss (Obesity/Overweight) "I started talking Alli February 18, 2016, I've lost 9 lbs so far (3 weeks)! Week one I did not change my eating habits but I could tell the pills were working due to frequent visits to the rest room. Week two, I started eating healthier and noticed that I wasn't using the bathroom as much. I did not rate alli a 10 because I was constipated for 2 days, although it could be due to the fact thag i am no longer eating greasy goods like I was during week one. Overall I love Alli and it is really working for me. Losing those 9lbs motivated me to keep going!!"

For Weight Loss (Obesity/Overweight) "Alli is a miracle drug. You must eat within normal guidelines to lose weight. I do not recommend binging out on foods because Alli will make you go to bathroom.. a lot! I eat 1200 calories a day, take 4 pills a day and exercise 5-7 days a week. I've been taking these pills for 1 month and lost about 11 pounds..( down 35 total now from 8 months ago) I take them 1 week on and 1 week off to give my body a break so technically 11 pounds taking them 2 weeks.. Definitely recommend"

For Weight Loss (Obesity/Overweight) "I used Alli years ago and it worked awesome, I lost a lot of weight in a relatively short amount of time. They took it off the shelves for a period of time and then reintroduced back to the retailers. I have tried it several times since the Alli has been back on shelves and it is complete garbage, waste of money and time. I could drink a whole bottle of olive oil and have absolutely no effects. What a waste........I meticulously follow the directions and it does not help shed any extra pounds."

For Weight Loss (Obesity/Overweight) "I was reading the reviews and could not believe people had so much trouble with oily leakage. It clearly states that you cannot eat high fat foods. If you think you can take Alli and continue eating all kinds of high fat and fried foods, then you will have the oily side effects that are CLEARLY stated in the accompanying literature. Alli works great when taken with a low fat, healthy diet. It helps remove about 1/3 of the fat from the food you eat. I have taken it for a month now along with weight watchers. I have lost 12 lbs. and only had one experience with an oily accident. That was due to the fact that I went to a Mexican restaurant the night before and ate with abandon. I knew better, but I did it anyway and took the Alli pill."

For Weight Loss (Obesity/Overweight) "I purchased Alli back in 2009 (Great worked a treat and lost weight) and since I have had two more attempts in 2014, now 2016. The product does not work at all. This time I have been taking for over one week, I have experienced constipation and flatulence. The product was purchased from reputable pharmacies and again i feel I just wasted my hard earned money. I am unsure what has changed. However, I know one thing the product is definitely not the same, I feel like the tablets are duds. No change to my weight, just embarrassing wind, stomach cramps, it makes you feel bunged up. no change to stool what so ever, not even if fatty food is introduced to diet. My advice is do not bother, I wont from now on. Hope this helps :("

For Weight Loss (Obesity/Overweight) "I started taking Alli the other day. I have had to purchase Poise pads, just in case of an oil gas or stool. I have read nothing but horror stories. But I am just experiencing extra bowel movements in the toilet. Mild stomach cramps. I wear the pads in case of anything due to side effects, but have had nothing at all. Lost weight already. But I am not hungry at all. I tried out the first day on a Sunday in case of adverse side effects. So far....so good. Hopefully this can be my go to for weight management going forward."

For Weight Loss (Obesity/Overweight) "The side effects were not worth any potential weight loss. I spent way too much time on the toilet. I wasn't even having bowel movements. I would sit there and "oil" for hours. I had accidents, and "oiled" myself with this nasty orange oil. I'd rather be a fat cow than have accidents in my pants."

For Weight Loss (Obesity/Overweight) "I started taking Alli 2x a day 10 days ago. I only had 15 pounds that I've been struggling to lose. It's curbed my appetite and I've lost 3 1/2 pounds in 10 days! The only Con if you eat a high fat meal you will be stuck on the toilet tomorrow morning. It will definitely remind you not to do that again. What I love about Alli no jittery diet pill side effects and rapid weight loss."

For Weight Loss (Obesity/Overweight) "I've lost about 5lbs in a little over a week. I'm not sure at this point how much of that weight loss has been from Alli or if it was from changing my diet and eliminating sugars and carbs. I can see the oily fat in the stools. Yesterday I made a BIG mistake and ate frys and a fried chicken sandwich. Since I have had two accidents, where my flatulance has spewed large amounts of oil into my underwear. Was not expecting that. Will not eat a high fat meal again on these pills."

For Weight Loss (Obesity/Overweight) "I took alli faithfully prior to the 2014 recall. It worked wonderful. I lost a lot of weight and inches. Since it came back on the market I have been taking it to lose again what I gained back and to help me as I quit smoking. It no longer works at all like it did prior to the recall. Something has changed in the product, what? I have contacted GSK for input, waiting for a reply."

For Weight Loss (Obesity/Overweight) "I am not obese but I decided to try Alli as a weight loss supplement to help with my diet because I have zero willpower. I like to eat and eat until I'm full and I like pizza. I was 5'8" and 160 lbs. 40D-29-34. Dress size M/8. With no diet change, I lost a few pounds using Alli. Enough to throw out some too big clothing. At day 90 I changed my diet and began eating healthier and there's a change in my body shape. I had IBS constipation but Alli removed the need for me to take prescriptions for my IBS. I don't have accidents but I am very regular now -like clockwork! And the Alli works for me to lose the few lbs. I needed to lose. I can fit into a 6."

For Weight Loss (Obesity/Overweight) "I took Alli when I was 20 years old and lost 60 pounds all of which I was able to maintain for the last 4 years until recently I have gained the 60 pounds back. I'm seriously thinking of taking them again because it motivated me to eat healthy and exercise. It DOES make you go to the restroom if you eat fatty foods but it really helps get your digestive track moving. Like I said I lost 60 pounds within the first 6 months of using it."

For Weight Loss (Obesity/Overweight) "I went through a weight loss program at my local hospital (protein shakes, healthy meal) I lost 48 pounds met my Goal August, 2015. Throughout my program and presently if I have a fatty meal I take an Alli maybe one every other day. It is amazing for weight loss maintenance in the past the pounds would be creeping I keep things in check but it is wonderful to occasionally have a treat. Highly recommend for post weight loss maintenance."

For Weight Loss (Obesity/Overweight) "I started taking Alli once I plateaued after losing about 12lbs and it has kick started my weight loss again. I am on a daily exercise routine and try to stay very active. My eating habits are not great but not bad. With Alli if you eat too much fat you will have "side effects". With my experience I have had soft stools with oil slicks and oily Flatulence which is unpleasant but a motivation to stop me from eating things I shouldn't be eating. It acts as a consequence to your stupid choices, which I need. After a solid week of taking it 3x a day with each meal I have lost 2 lbs this week. I was stalled for 4 weeks without any loss which is very frustrating! This works, hands down! 30 lb to go."

For Weight Loss (Obesity/Overweight) "I have been taking Alli for about 3 weeks now. I didn't have any side effects, but then again I had been eating foods with very little fat in it. I wanted to put Alli to the test so I ate some lasagna, which has a lot of fat content. After I ate that my bowl movements did contain a bunch of oil. So does it work - absolutely."

For Weight Loss (Obesity/Overweight) "The key to using Alli is that you must list everything you eat and not exceed the amount of fat per meal. I haven't experienced any side effects and am extremely pleased. I lost 10 pounds before starting the program and hit a plateau, but since using Alli, I've lost 27 more with only 13 pounds to go. When I reach my ideal weight, I'm going to continue the tracking, eventually weaning myself off of Alli, to be able to maintain my weight. I don't expect a quick transition, but love the results. I recommend trying it, but be diligent to follow the instructions for good results."
