For Weight Loss (Obesity/Overweight) "I almost decided not to try Alli because of the horror stories, but I'm glad I did. The first two days I had minor nausea and slight cramping, but it never recurred after that. I have followed the diet and fat requirements, and I have never had an accident or any problems; I am on week 4. The only slight day-to-day issue is minor constipation and a little gas. Not enough to make me stop taking it. I ate in a restaurant for the first time and did not have access to nutrition content and had no issues. If you are serious about diet and weight loss, give it a try and don't let the horror stories deter you."

For Weight Loss (Obesity/Overweight) "I've only been taking Alli for one week now. I also joined a gym and started a diet. I'm a 26-year-old female. Last Tuesday I weighed 278 lb, and today, Monday, I weigh 266 lb. I take a total of three pills a day, one each with my meals. I'm only at the gym for about an hour. I do about 3-5 miles on the bike or treadmill, then weight machines. My diet now consists of low calorie/low fat. Tons and tons of veggies and fruit, high protein. I think all the combination of what I am doing is why I lost 12 lbs within just six days so far. And trust me, I have hypothyroidism, so my metabolism sucks! As far as side effects, I have not had any 'bathroom accidents' that are apparently quite common. But like I said, I have been following the low-fat diet like the packaging says to do. The only thing I have experienced is lower back pain that feels similar to period cramps. But that could also be due to me joining the gym. I will definitely be finishing the bottle and hoping for even more results."

For Weight Loss (Obesity/Overweight) "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."

For Weight Loss (Obesity/Overweight) "I have a feeling that the people commenting that it 'doesn't work' are the ones expecting Alli to be a 'miracle pill' for weight loss. You CANNOT eat rubbish while taking these, it won't work. It's as simple as that. Yes, the pounds won't literally slide off you, but they assist you alongside a healthy, low-fat diet and exercise. I lost a steady 2 lbs / 3 lbs a week using these. Diet was full of fish, meat, fruit, and veggies, and I snacked on healthy nuts and seeds (I also took a multivitamin supplement as recommended). I did HIIT workouts and jogged 3-4 times a week. They work if you put the effort in and they're used properly."

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 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 lost 75 pounds when I used Alli. I ate low-fat foods like egg whites, low-fat yogurt, salads with chicken breasts & low-fat dressing, sugar-free popsicles, tomato soup, lean turkey, chicken, & turkey. I added salsa, green peppers, onions, & mushrooms to make the food go farther & for taste. Lots of lean protein. I took one Alli when I ate a meal that contained fat. I also started walking. I walked 3/4 mile at first, then 1 mile, & then 2. If I cheated, it wasn't fun! If I ate a piece of pizza & took an Alli pill, it gave me the oily runs which wasn't fun. That made me not cheat! When I stopped exercising and not eating right, I gained the weight back. It's like any healthy lifestyle, you have to make changes to lose weight!"

For Weight Loss (Obesity/Overweight) "I started taking 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 restroom. 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 that I am no longer eating greasy foods like I was during week one. Overall, I love Alli, and it is really working for me. Losing those 9 lbs motivated me to keep going!"

For Weight Loss (Obesity/Overweight) "Just want to update since previous review: To understand how this product works, you have to know what it does. It blocks a certain amount of the fat you eat from being absorbed into your body and thus reduces your calorie/fat intake. It's not a miracle drug. If you eat a very high-fat diet, yes, it may help a bit, but it won't do all the work. Also, if you eat little to no fat anyway, it can't help as it won't do anything for you. It can't block fat that isn't there. If, like me, you're on a long-term diet, it can really boost your success. I have gone from a BMI of 47 to 39 in 6 months. Still some way to go, but Alli is helping a great deal and keeps me motivated with consistent weekly weight losses."

For Weight Loss (Obesity/Overweight) "I never used Alli before but remembered seeing a coworker of mine use it and she was slim. This product works wonders. It traps all the fat and then releases it straight out of the body. It really helps with my gallstones so that my gallbladder doesn't cause any pain. I have lost 7 lbs the first two weeks. I am hoping to start seeing more weight come off as I continue using this product."

I am now 210 lbs, 6 lbs gone in 5 days! It has helped with my appetite. I will be honest; I do not diet or exercise, but Alli does really work! I would highly suggest it to anyone overweight!"

"I started Alli only four days ago and have already lost four lbs. I highly recommend reading the books included in the starter pack. Also, the calorie/fat gram counter book should become your new best friend. Not only has this product motivated me, it has changed my eating. However, I am a mother and a wife, and my family is extremely picky, so cooking two different lunches and two different dinners, one being only for me, is impossible. So, I have been only eating a tuna salad sandwich on whole wheat and a banana for lunch and dinner. Remember, everything in the tuna salad must be accounted for."

For Weight Loss (Obesity/Overweight) "I just started taking 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."

For Weight Loss (Obesity/Overweight) "I have been using Alli for a number of years, and I echo what many have already said. Alli seems to work in two ways, (1) Medical, by inhibiting the absorption of digested fat and (2) by offering a direct and timely feedback loop. Eating a high-fat meal? Alli will let you and your toilet know within a matter of hours. After a while, you learn to understand the relationship between food and fat. I have a small pill box of Alli that I take with me wherever I go, so I don't miss it at mealtime. With Alli, timing (both input and out) is everything."

For Weight Loss (Obesity/Overweight) "If you're having problems with oily farts, then you're not following the recommendation of a reduced-fat diet! That oil is fat your body isn't absorbing. Anytime it starts happening to me, it's my reminder I need to watch what I eat! I also have IBS. I now have regular BMs and haven't been as bloated. Also, my appetite isn't as strong; I'm not binge eating, and I'm not craving junk food as much."

For Weight Loss (Obesity/Overweight) "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"

For Weight Loss (Obesity/Overweight) "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"

For Weight Loss (Obesity/Overweight) "Just want to comment on an early review from someone saying it didn't work. The person has a BMI lower than this product is intended for and doesn't sound to eat a lot of fat, so this product is unlikely to work for them. I have a high BMI and found that it helped my weight loss to be more consistent than dieting alone. I have changed my eating habits and haven't had any negative side effects. You need to put effort in and can't expect it to do all the work for you."

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!"

For Weight Loss (Obesity/Overweight) "I'm on my second month, and or bottle of Alli. I tried it in the past, but I must admit, I ate fat and yes, had the loose bowel motion, but didn't gain weight. Now I only had 15 lb to lose, and so far, I've lost 7-9 lbs in a month, eating good. I did go on a week vacation and ate cake, drank cocktails, ribs, etc. Not every day, and yes, it came right out. Don't laugh, but I didn't gain a pound during the week. I'm not using it for that reason, but hey, now you can go on that cruise during your diet and not gain weight. Yes, you go to the bathroom a lot, but you know it's all coming out. For the most part, I'm 90 percent on track, with no side effects. And if I eat pizza and nachos on Friday night, so what, I don't gain weight and for once I'm not constipated."
