"Do not waste your money, I repeat do not waste your money. I have been taking alli over a week now and it has made me bloated and I even gained a pound. Last night was the last straw, as I was washing my hands I had a orange oily accident and this is was so embarrassing it leaked through the shorts and I almost cried. Now I'm stuck with a bottle of capsules and out $70 a complete waste."

"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 12lbs. 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 and soon!"

"It does what it says, so 3 stars. If you like orange oil coming out your butt, missing work, and fryer grease farts, then you'll like Alli. I'm thinking, if you don't have a lot of fat in your food, then it might be tolerable, but I'm not willing to find out. "

"I've been taking alli for 3 weeks (only on week days with a bit of cheating at the weekend) and I've lost half a stone. You won't get any nasty side effects as long as you limit your fat intake to less than 15g a meal and avoid high fat foods. It's not a miracle drug, you can't just take it with an unhealthy diet (you will get the side effects then!) but with a healthy diet and exercise it increases your rate of weight loss. I think it's worth the money."

"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!!"

"I took Alli because I just wanted to shed 15 pounds. At first I was starting to lose weight but then I ruined a few pairs of pants and a bedsheet thanks to the embarrassing and unexpected oil leaks. lol. Needless to say, it’s not worth the discomfort and embarrassment of being out in public and not knowing if/when you’ll have a very noticeable accident."

"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."

"Was taking many medications for a condition which caused a lot of weight gain. After weaning off, dr. put me on low cal, low carb diet with a prescription diet aid that worked but scary. I continued ti lose after stopping rx diet pill but then plateaud for a long time and started gaining slowly. Chose Alli to help things start moving along. So far I'm pleased. Psychologicaly, it helps motivate me since I spent money on an FDA approved diet pill. It helps so I can eat meals a little higher in cal than original diet which makes it more sustainable. In 3 days I've lost 3 of the 4lbs I gained back. I exercise almosr daily- for years. Try to make healthy choices and not eat late. Take with lunch and dinner where my fat and calories are a more"

"started Alli feeling unhealthy, no energy, not much bowel movement. 5'5 weighing 195lbs. I know most of its fat I use to lift weights years ago in younger days when I was fit. I had pregnancy diabetes Dr said if I didn't keep weight under control I'd be a diabetic later in life. Once I had baby I no longer had to take insulin but 20 years later I'm overweight. I started Alli went from 195lbs to 190lbs lost 5lbs in one week. My bm's are more consistent, I feel more energy. I walk about a mile each day, I try to watch what I eat so that I don't get oily stools with stomach cramping (Feels like menstrual cramps) sometimes I splurge on a steak dinner when my husband takes me out to dinner the rest of week it's one piece of lightly buttered toast with cup of coffee sugar/cream and an apple for breakfast, tuna sandwich with apple for lunch, and airfryer chicken or fish filet for dinner. It's been only one week on Alli I'm determined to lose 45 more lbs"

"I took Alli for 2 months when it first came out last year. I didn't experience any effects because I stuck to the diet. Reading what could happen if I went over my fat grams scared me. I stuck to it and went from a size 18 to 14. I stopped taking Alli and during the winter gained some weight back. I recently decided I was going to go back on it."

"I just started to take Alli. So far I have been feeling great about eating right. Taking ALLI makes you accountable for what you eat. For me the side effects are scary enough to make me eat right. All of the reviews I have read, have made me so excited to lose weight. Thanks everyone"

"I think most people expect changes in body too quickly. I have been on alli for three weeks I am down 4 lbs. I am eating smaller meals and in a consistent exercise plan. I never expected alli to make me rock hard after a month. I plan to use for 2 months to help kick start my second 15 lbs. Alli works if you follow restrictions not going to work with an extremely fat meal. This is supposed to supplement a new life style change. If I only lose 3 to 4 pounds more I will be happy. I am not expecting alli to work after 3rd month. I have 6 more pounds to lose before vacation and another 8 to 10 this year. The lesson is you still need to watch how much you eat. You also need to be active 3 to 4 days a week period. 15 lbs this year and 15 next"

"I am not obese, just wanted to lose 20 lbs that I have not had luck shedding over the years. I have been taking Alli for 3 months now and have not lost any weight. It did however, help me from being constipated. If you're having trouble pooping, Alli will help."

"I have been taking Alli for 2 weeks and have experienced the good and the bad. I am satisfied with my experience so far. My negative side effects were completely my own fault as I did not watch what I ate one time and regretfully experienced the effects. The positive side is that if you follow the plan and keep the fat under 15 grams you will be fine. I am continuing with Alli."

"I have used Alli for approximately 4 years to control weight from getting worse. I depend on it being diabetic and it has now been recalled. I take up to 4 x 5 pill servings of high quality fiber but without the Alli I am having a horrifying time with bowel movements and rectal bleeding. The bleeding was going on while taking Alli but is worse without. I know there have to be others like me that need to relate as well,and that IS POSITIVE!"

"The moment I hit 30, my metabolism slowed. Despite working out and eating healthy, I felt bloated after I ate and I was irregular. I really felt like my body was overloaded and not processing things at a normal speed but I felt lethargic and hungry so I was starting to get depressed over the whole thing. I tried diuretics/lax and increasing fiber to no avail and the cramping sucked. This is making a real difference. I feel leaner and lighter and my joints aren't so overtaxed carrying the extra weight. My energy is way better. It's messy at times and not easy but if you have two weeks of down time where you can be by the bathroom, give this a go."

"Used for 12 days. Not a pound lighter. 5'6/150. Just need to loose 5-7 pounds for summer. No time to go exercise now: lots of physical work plus yard. Eat mostly salads and soups already, sugar too but not a lot. My husband was taking it too. No change. We both are active, usually go to the gym 3-4 times a week. I have mild metabolism and he has slow metabolism. It's very hard for both of us to lose a single pound. We did notice BM and I think I noticed more hair loss in me. Did take multivitamins plus calcium. After reading online about all the side effects, recall and bad experiences - I decided to put it aside."

"This is my first week on Alli. I am taking it as directed. I have experience one accident with a BM. But other then that it's been fine. I really have to watch what I eat because I will pay for it later. I haven't weighed myself yet. I will on Friday just to see if its really working. I'm not doing any excerising."

"I have been taking Alli for approximately 2 weeks now. I weighed in and seemed to have gained weight. I am 5'1 ,158 lbs starting weight. I now weigh 166 lbs. I try to watch what i eat but have a very hard time. this product is recommended for those with excellent self control. i do however know that the product is working as they say it will due to the change in bowel movements."

"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."

"I've been using Alli for several months, with a good diet, and I exercise when I can, but at least a few times per week and I have not lost a single pound on Alli. I get the shits and all, and that is surely no fun, but besides that there is no proof that these pills work. Simple as that."
