Xenical (orlistat) "So I started just over a week ago, if you eat something high fat you get major tummy troubles. But if you stick to low fat things it’s brilliant. I am on it due to an under active thyroid hindering my weight loss with weight watchers. I have a lot to loose, last week I was 167.6kg 1 weeks later I’m 162.5. So in 1 week I've lost 5kg! Amazing, I will be sticking with them. They also encourage me to make sensible choices in my diet. The only side effects I've had other than the upset tummy’s are burping a lot and loss of appetite, both of which I can live with."

Alli (orlistat) "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."

"Hiya, I've been taking orlistat 120mg for 11 days. I've lost 1st and 4lbs so far! I am off the scale obese so I needed to loose a chunk of weight in order for me to have the willpower to carry on. I have no more than 3g of fat in each meal, I take a multivitamin at night as directed. I feel great on it....just hope I manage to continue. I have had no major issues, no oily stools. Eating lots of fruit and veg and drinking loads of water. I still have my no Sugar fizzy pop and my cups of tea and coffee."

Alli (orlistat) "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."

"I started taking orlistat yesterday morning, and weighed myself this morning to find I'd already lost 5lbs. I'm actually amazed. I've had no side effects so far so I'm really happy. I have been exercising and eating healthy for the past two months with only minimal weight loss. I have to lose 7kg in 3 months for them to continue giving me this drug and so far I can't see that being a problem! Will update in a few weeks with my progress, very pleased so far"

"I tried Orlistat years ago but was ignorant towards its use (not controlling fatty foods and having lovely sunset yellow accidents), so gave it up. I have struggled with PCOS (Poly Cystic Ovaries Syndrome) since the age of 17 and one of my symptoms has been WEIGHT. Always been overweight and when I do diet and exercise the hormonal imbalance will make it harder to lose the Ib's and I gain muscle instead. After two kids its become harder to lose any weight and decided to go back to prescribed Orlistat. Now 4 days in, bloated, flatulance, no accidents, looser stools and bloatness goes away after relieving myself. Not weighed myself yet. (2nd day I felt dizziness, but no more). I'm careful with fat consumption and try not to snack in between meals."

"If you don't make a significant change to your usual intake of fatty food oils pastries etc, then you will find a very unpleasant leakage of yellow oil soiling your underwear, as anything oily you have eaten is excreted and accidents WILL happen. It is not just about taking a tablet to lose weight, it is also about making changes to what you eat in order to prevent such side effects from happening. There is a positive however as cutting down on fatty/oily foods will also help you lose weight."

Alli (orlistat) "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!"

"I started orlistat one week ago prescribed by my GP for weight loss aid. Last Monday I weighed 15 stone on the button. Today I weigh 14 st and 8 lbs. So approx 6 lbs weight loss in just a week. In honesty I haven't changed my diet that much. I always eat relatively well at work. My breakfast contains little or no fat, my lunch is mainly healthy but I still eat crap in the evenings through boredom. I haven't done any exercise yet but MUST start. I experience the oily stools at least 3-4 times per day. I take 3 tablets per day around 15 minutes after each meal. I did read some reviews that said "the worse you eat, the more you lose" I don't know if this is true I just know that it is different for everyone."

Alli (orlistat) "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."

Xenical (orlistat) "My family physician prescribed Xenical 120mg 7 days back, and I was 90kg when I started. I couldn't exercise, and my diet was the same as before. I used to have a low-cal, low-fat diet for years, but nothing happened over the years except for gaining weight. This pill is miraculous! I lost 3kg in just 6 days, and I didn't have to go through any of those horrible side effects. I only took 2 pills per day. Hope to continue this for 3 months, and my target is to reach 58 kg and be sexy again ;) . Fingers crossed!"

Alli (orlistat) "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"

Xenical (orlistat) "This drug works but you need to be aware of the side effects. Though expensive (I'm in Australia, I don't know US prices), it's worth it as long as you eat and exercise properly. As it stops approximately 30% of the fat you digest from being broken down, you can lose fat-soluble vitamins. My pharmacist suggested using a multivitamin an hour before my first meal or 2 hours after breakfast so Xenical wouldn't stop the vitamins, though talk to someone before listening to this advice. If you eat anything with a high-fat content, you will probably poop your brains out. While visiting my dad, he made meat pies and I had burning diarrhea all night and the following morning. So don't do that, or if you choose to eat it, just skip the pill for that meal."

Alli (orlistat) "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!!"

Xenical (orlistat) "I started at 72 kgs., but after 6 DAYS of taking this pill, I lost 4 kgs!!! I am so happy about the progress and I hope this will continue. I am planning to take this for about 6 months so I can get back to my normal weight of 42 kgs - that was my normal weight before I gave birth. Hopefully, this amazing weight loss would continue. I am trying to avoid oily foods and I have been eating more green leafy vegetables. I think it's working well for me. I'm not being bothered by oily stools anymore since I've been eating less fat and more fiber. Never had any 'disturbance' at work as long as I avoid fatty foods at work."

"It worked for me, I am not obese but I am fighting for years to lose 10 punds or not gain more, so, whenever I go on vacation and I stay at all included hotels I use this pills just to balance the oil intake. so, if I go to eat pizza I take the pill, if I eat an oily meal I take the pill, if its December I take the pill. Not daily and not on every meal, just the oily meals. It is just an extra help, that is all."

Alli (orlistat) "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."

Xenical (orlistat) "Ok, so it played nice with me. No side effects, nothing, well, until I had instant noodles. It's been three days, and I'm still running in and out of the toilet. I've literally been manufacturing oil in there, bright orange; it's disgusting. I'm never taking noodles for the rest of my life. As for my weight, I've lost 4kgs in a week. I feel great. Warning: stay away from oily foods. I learned the hard way."
