For Weight Loss (Obesity/Overweight) "I started taking Alli 3 months ago. After chemotherapy some years ago and being forced into menopause at the age of 44, which plummeted my hormones , hormones help your body combat fat absorption and fat burning, I had to do something. I went from 138 to 172 in a few years of life without normal hormone levels. After one month of ALLI I dropped 12 lbs. I stopped taking them and the weight came back on. Having hypertension i am doing: I take an Alli with meals that have fat content over 10g. Yes I have fluorescent orange oil in my stools that means fat is leaving my body. I cut my food intake by one third, nothing too drastic, and I am not left ravenous. Mediterranean Diet is adhered to and normal daily exercise. I do have a once a month cheat day and Pie is always on the menu that day. Moderation is the key. Don't be hard on yourself, your not lazy , you need to take baby steps and be kind to yourself. Ignore the name callers on here, they are not very compassionate."

For Weight Loss (Obesity/Overweight) "Not only am I premenopausal, but I also have no gallbladder to break down the bile. Since my surgery and going into menopause, I have gained over 20 lbs. I needed something to help more than most people to eliminate bad fat and flush it out. After just a day or two, I noticed it doing its job, and I actually feel a lot better too. I don't have that bloated or feeling too full sensation. I made sure to start this on my weekend to ensure everything would go okay and I wouldn't have any accidents. I noticed as long as I follow the simple plan of a lower calorie or lower-fat diet, and just take one with my higher-fat meals, I haven't had any problems. I lost 3 lbs in 6 days so far, so I'm actually pretty impressed. I also think this is a good product to take for those who are trying to lose weight with no gallbladder or going through menopause, those pounds that sneaked up very quickly."

For Weight Loss (Obesity/Overweight) "Been using this medication for a little over a week. My observations are the following: 1. Do not fart unless you are on a toilet. Unless you don’t mind the orange skid marks. 2. Keep a toilet brush handy to clean your bowl after you flush your gross stool. Unless you don’t mind a dirty toilet. 3. Again, hold those farts in until you find a toilet. Just avoid being around people smoking unless you want to cause a fire from the gasses you release."

For Weight Loss (Obesity/Overweight) "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."

For Weight Loss (Obesity/Overweight) "I started using this on 02/20/14 and use every day (as directed) and have not had one 'side effect'. Changed my eating habits and doing Jillian Michaels 30 Day Shred and am down from 201 lbs to 195 lbs today. I don't know if it's 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 45 lbs off."

For Weight Loss (Obesity/Overweight) "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."

For Weight Loss (Obesity/Overweight) "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."

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 bowel movements did contain a bunch of oil. So does it work - absolutely."

For Weight Loss (Obesity/Overweight) "Ok, so I started taking Alli for weight loss back in June. I dropped 7 pounds in 7 days by exercising, dieting, and drinking water. I will admit, make the toilet your best friend, and if you're a female and very gassy, grab a pad or pantyliner. It gets nasty. You have to eat for your body type, and do what is needed to shed pounds. DO NOT think popping 3 pills a day will magically induce weight loss. FOLLOW THE INSTRUCTIONS."

For Weight Loss (Obesity/Overweight) "I take Alli on and off, it is helpful, but today was different. As I was sitting in the office, I felt my downtown area wet, then I went to the restroom. The moment I was doing #1, then #2 started coming out as well, and when I looked in the toilet it was oily (red). To tell you the truth, I lost 20 lbs already."

For Weight Loss (Obesity/Overweight) "My doctor suggested Alli to help me lose weight. I took the medication for 6 months at twice the over-the-counter dose. I ended up gaining 10 pounds during the six months because I consumed too many carbs. Side effects were not an issue for me. My doctor told me to stop taking Alli and switched me to a keto diet. The keto diet has been yielding good results for weight loss. I rated the medication a 5 out of 10 because I don't think that Alli was the reason that I did not lose weight. I failed to watch my calorie intake while taking Alli. I also recommend Alli to those who are able to get on a calorie-restricted diet while taking the medication."

For Weight Loss (Obesity/Overweight) "I am reading all these great things about Ali and I’m so disappointed… I got so Very ill after I took it. I honestly thought I was going to die. I’ve looked for drug interactions and I can’t find any with the medication I take. I’m on an opiate pain reliever for my back. I took Ali with my lunch and felt like I got the flu within an hour body aches chills almost like I was withdrawing from my pain medication. But then I read and searched on the Internet and didn’t find any interactions so I took it again with my dinner . This time I broke into a sweat, profusely sweating had chills so bad that was violently shaking was so dizzy that I couldn’t even stand up I was nauseous, My muscles started cramping up and I couldn’t breathe…(I might have been panicking and I do have asthma ) and then after about two hours it went away again. It was a very scary experience and I thought about going to the hospital but I couldn’t even walk across the room to get to my phone."

For Weight Loss (Obesity/Overweight) "This pill has worked for so many people so I thought I would give it a shot. I go to a dietician regularly for food allergies so my diet is already very healthy and effective. I took Alli not only for weight loss, but mostly because I had heard from friends it would help keep me regular. I will say if you cheat on your diet do not take Alli you will have oil movements instead of a normal bowel motion. However, even in my instance Alli caused me serious stomach issues. Although I did not have accidents I did have feelings that I was not going to make it to the restroom or extreme gas. This pill all depends on your body chemistry. Even with a good diet sometimes it will not work. However, I did start taking a veggie fiber after Alli and it has great benefits"

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."

For Weight Loss (Obesity/Overweight) "If you have no gallbladder, you may want to think twice. You need to read the manufacturer's information regarding side effects. Alli helps the body separate 'fat' through elimination, and if you have no gallbladder, the bile problem can be miserable."

For Weight Loss (Obesity/Overweight) "Well, let me say that I read through everyone's posts prior to posting. I used ALLI and found it to be exactly as stated. I no longer use this product. Losing weight is about getting off your big butt and making the appropriate choices! MOVE and EAT HEALTHY! I run daily and I make wise food choices for the most part, and when I don't I KNOW that I WILL BE THE ONE to SUFFER! I am the one who pays the price for the choices that I make! Time for people to start taking responsibility for themselves and stop trying to make someone else the scapegoat. If you want to lose the weight, cut back on calories and move your body - that is the key!!!! Come on people, it isn't rocket science! I did it and lost 112 pounds. Not easy but you can do it!"

For Weight Loss (Obesity/Overweight) "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. "

For Weight Loss (Obesity/Overweight) "Recently purchased alli tablets from chemist, after two weeks my liver and kidneys started hurting so much that I had to stop taking them. I emailed GlaxoSmithKline who said that they was aware that possible liver failure may result. As they originally removed them back in 2012. And they wanted me to sign a consent form (basically wanting me to keep on taking them as their guinea pig) for their research. "
