Does alli work as a weight loss pill? The quick answer seems to be yes, but there is a downside, so read on.

Alli is the over-the-counter name for orlistat which is also available in prescription form as Xenical. If you are going to ask for it you may like to know that it is pronounced like ally, not alley. It is essentially a fat blocker. It works by preventing the body from absorbing the fat from the foods that we eat, and it is the one freely available drug that has FDA backing for its claims to aid weight loss. You might think you could eat all the fatty foods you liked and then take alli to negate the effect but sadly that is not true. It should always be used in conjunction with a low fat diet plan under the supervision of a doctor.

The amount of weight loss achieved with alli is variable. In one study involving one-year clinical trials, between 35.5% and 54.8% of subjects attained a 5% or greater decrease in body mass, although we do not know how much of this mass was fat. Between 16.4% and 24.8% of the subjects achieved a 10% or more decrease in body mass. In combination with a calorie controlled diet, the effects could be expected to be greater. It was also shown to reduce the risk of developing type 2 diabetes. The participants regained an average of one third of the weight that they had lost after stopping alli, but this is typical of most dieters.

The main disadvantage of alli is the side effects which center around digestive and bowel problems. The higher the fat content in the diet, the greater these side effects are likely to be, as the undigested fat is expelled from the body. Flatulence, loose stools and bowel incontinence can result, especially in the early stages before the body is accustomed to the drug. The manufacturer's website warns, "You may feel an urgent need to go to the bathroom. Until you have a sense of any treatment effects, it's probably a smart idea to wear dark pants, and bring a change of clothes with you to work." You really need to want to lose weight to take alli!

However these side effects are reduced if you stick to the recommended low fat diet and as the manufacturers hint, the potentially embarrassing side effects can even be helpful in encouraging you to keep to your diet. Always remember that alli does not claim to work without consistent efforts toward weight loss from you. What they do claim is that it can improve your weight loss by up to 50%. That would mean a person who lost 10 pounds without taking alli would lose 15 pounds taking it. It boosts your weight loss and rewards your efforts with better results than you could get by yourself. Note though that individual results will vary and are not guaranteed.

Sadly there is no magic diet pill that will melt away your excess pounds while you sleep, but alli is a pill that has documented results. If you are determined to lose weight and have been struggling with diets without much effect, it may be a good time to discuss it with your doctor and find out does alli work for you.  Healthy fat loss

Many people are now turning to inexpensive and natural green tea weight loss plans to help them in their weight control efforts. It is simple too. Green tea can be drunk like any other tea, usually without milk or sweeteners, or if you do not like the taste you can purchase green tea extract.

Research has shown that green tea helps to reduce weight by stimulating the body's thermogenesis process, which increases the expenditure of energy and the oxidization of fat in the body. Many compounds found in plants have this effect. The special thing about green tea is that it does not increase the heart rate, and is therefore believed to be safer than diet pills such as ephidrine that also work by stimulating thermogenesis.

A lot of people who are overweight have or are at risk of developing hypertension and other cardiovascular problems, so the fact that green tea does not put pressure on the heart makes it a good choice. Ephidrine is not usually recommended if you are in this group but green tea is considered a safe option. It means that you can gradually increase your exercise levels without increasing your risk of heart problems.

There are only two ways to lose weight: one way is by eating less (consuming fewer calories) and the other is by increasing expenditure of energy (using up more calories). Green tea works by increasing output and this can be by around 4%. Most scientists believe that this is caused by the high quantity of catechin that is in the tea and its extract.

Green tea has the added benefit of containing powerful antioxidants that may be beneficial to your health in many ways, strengthening the immune system and protecting against disease.

Keep in mind that green tea does contain caffeine so you should cut out coffee and other forms of tea while you are taking it. Decaffeinated green tea is not recommended because the chemical processes that are used to remove the caffeine may destroy the beneficial properties of the plant.

At the same time you will need to exercise control in what you eat. If you eat more to compensate for the calories that are burnt by the tea, you will not lose any weight. Keeping to the same calorific intake that you have now and taking green tea should result in gradual weight loss and better energy levels over a few weeks. You can of course increase the speed of this by reducing calorie consumption and/or increasing exercise.

Green tea is a simple, easy and inexpensive weight control aid that can easily be incorporated into any weight loss program. The choice of tea or extract offers something for everybody. Natural and safe, green tea weight loss should feature in your program if you want to keep the weight off permanently.

You will find a free list of negative calorie foods below, but first let's consider what this means. There is no such thing as a negative calorie - a calorie is a unit of heat and it cannot be negative. So when people talk about negative calorie foods, this just means a food whose calorie level is low enough that it takes more energy to eat and digest it than the food contains.

For example, if you consider water to be a food, then cold water is certainly a negative calorie food. It contains no calories at all and the body has to expend energy to bring it up to blood temperature. So every time we drink a glass of cold water we burn up a couple of calories and lose a little weight. But there are very few foods like this. Most foods that are on the list do not really use more calories than they add, or if they do the effect is negligible ... until you remember that at the same time the body expends energy just to keep alive and breathing. Celery for example does not give us enough calories to cover both the energy that it takes to digest it, plus the energy that we expend even when we are doing nothing. So that is why people call it a negative calorie food.

Negative calorie foods are most attractive to anorexics. A negative calorie diet would obviously result in starvation in the long term and nutritional deficiencies can occur surprisingly quickly. The calories burnt usually come from muscle mass, and the result is debility and wasting.

A more healthy way to use a negative calorie diet is as a form of fasting or detox. It is something you can do for one to three days right after the Christmas season or another time when you have been eating a over-rich diet. Provided you are otherwise healthy it can be a great way to clean out the system. However it is still best to take medical advice before attempting this.

If you decide to use a negative calorie detox, keep the following points in mind:

1. It is never a good idea to eat huge quantities of one type of food, especially fruits. A lot of foods contain substances that can be damaging if consumed to excess. For example, the acid in grapefruit and pineapple can damage your stomach lining. Other foods put an excessive burden on the liver or may cause diarrhea. So try to use all the different foods in small quantities.

2. Do not spend all day eating. You will just become bloated and feel sick. If you are only doing this for a couple days, you should not feel too hungry. Plan four or five salad meals each day, and let your digestion rest at other times.

3. You will feel more satisfied if you eat slowly and chew your food thoroughly. You will also use more calories that way. So if the foods can be eaten raw, that will be more effective than cooking them. Foods like carrots and beets will also be more satisfying if you eat them grated.

4. Schedule time when you do not have any important commitments. As with fasting or any kind of detox, you may suffer some uncomfortable symptoms including headaches, tiredness, depression and irritability. If these become severe, stop the diet and see a doctor.

5. When you end the detox, plan a gradual return to normal eating.
