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 purchased Alli at Target. It worked for me. I have only been on it for 2 months. I went from 238 lb to 226 lb. I am happy with the results so far. I am on the path of getting gastric sleeve surgery, but I might not do that if this continues to take off the weight. As long as I eat healthy, there are no side effects, but I do occasionally cheat and deal with the side effects then. It's no big deal though and worth it to me."

For Weight Loss (Obesity/Overweight) "So one year after having my twins I decided to start losing my baby fluff. Started at 203, got to 191 and hit that first plateau. I took a small break and allowed myself some time to adjust diet and exercise. I got to 186/188. Then I hovered there for FOUR WEEKS. Beyond frustrated. I ordered Alli from Amazon and I take it with lunch and dinner. I have had burgers after a five mile run and an iced nonfat coffee on our trips town. I have not had the serious explosive side affects that have been mentioned but I HAVE had wonderful results. I dropped three pounds two days after taking and that’s when I had the dang burgers! (Plain home smoked burger on a bun btw... not a McGross anything) and I hit 184 the next day. I did not have a crazy bowel movement either. This product will work if you use it correctly."

For Weight Loss (Obesity/Overweight) "I've had no side effects and no weight loss after 3 months, so my physician told me to stop taking the pills. My labs all came back normal, so no thyroid, Cushing's, etc... it was so frustrating! Then, because of the Covid, everything was telemedicine and I got a new physician via Zoom call and she requested a new set of labs and told me I had pre-diabetic insulin resistance. That changed everything! My diet had to change yet again. I'm following more of a high veggie and low any type of carb diet, PLUS the Alli and I am *finally* losing those darn menopause pounds that, literally, sneak up on you. What am I saying? Take Alli to help with weight loss but if it doesn't work, you need to keep working with your physician to get the right combination of diet & exercise for Alli to work. For you pre-menopausal and post-menopausal women out there; keep at it! The weight does, eventually, come off and you don't have to starve yourself or have risky surgery to do it."

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 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) "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) "This is the only diet aid that I would use. It is non addictive, and does not cause the jitters or sleeplessness. It's easy to use and it does the job. I've use Alli selectively off and on if I've had fat in a meal for many years. We aren't supposed to eat high fat, but it's satisfying and helps prevent carbo bingeing. And not every meal contains significant amount of fat. It also helps if you need to drop weight fairly quickly. All of the rumours about Alli are true. You will need to move your bowels more often and you may get I need a bowel motion type cramps. They say some of the side effects are deliberate, to prevent you from chowing down on a heaping plateful of ribs. Once, just once, I had an accident - fortunately, I was at home."

For Weight Loss (Obesity/Overweight) "I agree, the awful side effects only happen when you deviate from the low-fat, reduced calorie diet. I have tried so many things and this is really the only thing that has worked for me. I have been taking it for a month now and have lost 6 pounds! In the past, I was only able to lose about half a pound a week on low calorie diets (fasting, intermittent fasting, Whole 30, weight watchers, etc). I have not had any accidents because I am afraid to eat anything that might make the side effects occur. It is such a great deterrent for me and it is working! I plan to take it until I lose another 30 pounds."

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) "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 effects if I ate something I shouldn't have. Years later, Alli was on the shelf after I went to the doctor in need of help to lose the pesky 10-20 pounds. My doctor told me to use Alli but double the dose, as 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, know your portions, and drink plenty of water!"

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 lose 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) "I used Alli because I wanted to lose weight but needed help with commitment to my diet. It's been about a week and I lost 5 lbs. Surprisingly, it helped with my bloating and constipation, which may also be why I lost 5 lbs in a week. Not looking for a miracle pill, just something to help out, like a guard rail at the bowling alley. You may not get a strike, but at least you didn't get a gutter ball! lol"

For Weight Loss (Obesity/Overweight) "Worked brilliantly. I cut down my fat intake a week before starting them and continued this while on them. I lost 10 lbs in my first 2 weeks!! Really pleased with the result and have just ordered my second month's supply. You HAVE to reduce your fat intake to stop any unpleasant side effects. I'm now at the point where I don't want to eat high levels of fat because I don't want to suffer the consequences!! Worked for me!!"

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 went through a weight loss program at my local hospital (protein shakes, healthy meal). I lost 48 pounds and met my goal in 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 back. I keep things in check, but it is wonderful to occasionally have a treat. I highly recommend it for post-weight loss maintenance."

For Weight Loss (Obesity/Overweight) "Alli works great for me. At first, I lost 30 pounds in less than a year, stopped it for a while, gained some back but went back on it and lost another 12 lbs. I have been off it for 4 months because of the latest recall and am trying to be good. I loved Alli because bowel movements were regular and I didn't have to take it unless I ate more fatty stuff than I should. When will it be back? I hope it does come back soon!"

For Weight Loss (Obesity/Overweight) "I have used Alli and was very happy. It absolutely will help you lose weight. If you are planning on not adjusting your diet, it is not for you. Since it inhibits fat from being absorbed, fat goes right through you and could definitely be embarrassing (if you know what I mean). If you lower the fat in your diet, it will do wonders and the disgusting side effects will be minimal to non-existent."

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."
