Alli (Orlistat) Diet Pills Review

Young Woman Holding Yellow PillsIt is very difficult for people to lose weight. In a research, it was found that around 85% of Individuals cannot follow the traditional weight reduction techniques (1).

The failure of traditional weight loss methods encourages people to look for other substitute techniques like using diet capsules and pills.

Alli is an example of a diet tablet, which is based on pharmaceutical sciences rather than a plant or a herb and it is considered effective for losing weight.

This drug helps in losing weight by restricting the quantity of fatty acids being absorbed by our body. The lower absorption of fatty acids in turn effects the actual calorie intake and results in weight loss.

This article provides you with a detailed analysis of Alli diet pills: what are they composed of, how they help you in reducing the excess weight, and is it beneficial for you to consume them.

What Is Alli (Orlistat)?

Orlistat, a medicated weight reduction drug, is sold as Alli diet pills in the market.

One of the stronger version of the drug is provided to customers on prescription only. It is known as Xenical. A typical Alli Diet Pill contains 60 mg of the compound orlistat whereas Xenical pills consists of 120 mg of Orlistat that is why it is far more effective on obesity.

FDA approved this drug in 1999 and it is mostly prescribed by doctors for long duration obesity management treatments with a low, calorie restricted diet.

In short: Alli is the non-prescribed adoption of orlistat, a medicated drug for controlling weight. Orlistat is also available on instructions of doctors by the name of Xenical, in a stronger and effective form.

How Does Alli Help?

Alli Diet Pills

The main function that Alli performs is preventing the absorption of dietary fat in the body.

Lipase is an enzyme or a stimulant in the stomach that is specifically blocked by Alli pills.

The main purpose of Lipase is to digest the fats that we take in our diet. It helps in breaking down the glycerols or fats into three types of fatty acids, which can be recognized and used by our body.

In the absence of this enzyme, fats in our food are not digested in the process of digestion and are removed from the body.

The use of Alli Pills has demonstrated to curtail the absorption level of fats by approximately 30% (2). Alli works as a lipase-inhibitor, that stops the enzyme to react with fats for breaking them in fatty acids.

As the fats are high-calorie macro nutrients, the inhibition of absorption of these fats results in lesser calorie production in the body that can help in losing weight.

In short: Alli interacts with lipase enzyme that restricts the absorption of fats to about 30% of the total absorbed facts. This helps in lower absorption of fatty acids by the body resulting in weight loss.

Alli Can Help You Lose Weight In Small Amounts

A large number of researches have been regulated on orlistat, an active chemical in Alli diet pills.

Among these studies, the Swedish study by the name of XENDOS is well recognized. In this study, 3,305 obese individuals participated and results were observed over a period of 4 years (3).

The individuals were divided into two groups. One group took 120 mg dosage of orlistat, thrice a day whereas the second group of the experiment was asked to take a placebo.

All contributors of the study were allowed to take less than 800 calories daily and were asked to restrict fat intake in their diets to 30% of the total calorie in take. They participants were also advised to include walking in their daily routine.

The following graph illustrates the changes in weights by individuals in both the groups over the 4 years time (3):

Orlistat Weight Loss, Small

In the first year, the group that was treated with orlistat lost 23.3 pounds or 10.6 kg of weight on average. On the other hand, participants in the placebo group lost 13.6 pounds or 6.2 kg of weight only.

The graph also reveals that in the next three years, there was a significant weight gain in both the groups of the experiment. In the end,  patients who used orlistat lost 12.8 pounds  of weight in comparison to 6.6 pounds  of the placebo group participants.

This study concluded that orlistat along with controlled diet and proper exercise can help you in losing double the weight when compared with using diet and exercise as the only solution for weight reduction.

More Researches

In a research study, it was proved that adults consuming orlistat lost 7.5 lbs  more than the placebo group in the previous 12-months (4).

This weight loss  is equivalent to 3.1% of initial weight that is not exactly huge. It was also observed that weight returned  after they quit taking the drug.

Astonishingly, the results of another study concluded that the effects of a low-carb diet without drugs were same as using orlistat and a diet lower in calories together (5).

In short: Alli/orlistat is an anti-fattening drug that results in losing 3.4 kg(7.5 lbs) more than placebo in 12 months.

Do Alli Diet Pills Contribute to Health in Other Ways?

Some of the other health advantages that have been attributed to the use of Alli, possibly because of weight loss, includes:

  • Reduced risk of type 2 diabetes: risk of getting Type 2 diabetes was reduced by 37% with 4-year use of orlistat, according to XENDOS study (3).
  • Reduced systolic/Diastolic pressure: A reduced blood pressures have also been seen in patients (6, 7).
  • Reduced cholesterol level: A positive influence on cholesterol levels has also been observed in various studies (6, 8).

In short: Long-term use of Alli may lessen the risk of type 2 diabetes and benefit in prevention of other diseases that can instigate heart problems.

Side Effects, Dosage and How To Use

Young Woman With Stomach Issues

Some side effects have been observed in the people using Alli diet pills, however, they have been documented and are available for the users of Alli Pills (9).

As these pills inhibit the breakdown of fats, the existence of large molecules of fat in the stomach can cause digestive problems like abdominal pain, diarrhea, and flatulence.

Fecal incontinence and loose, oily stools can be among some of the problems faced by the users of Alli Pills

Prolonged usage of Alli diet pills can also hinder the digestion of essential nutrients like vitamins A, D, E and K.

That is why it is recommended to take multivitamins with the treatment.

Alli Pills have been reported to intrude with the digestion of some medications. In addition, liver failure and kidney problems have also been noted in the patients.

People should seek advice from their medical consultant before consuming Alli diet pills, especially in case if they are taking any sort of medications for a disease or have a specific disease.

On the basis of a confined long-term description of the available results, most scientific studies suggest that Alli must not be used for 24 months or 2 years continuously.

The optimally dosage that has been used in the researches is 120 mg, thrice  a day.

Alli diet capsules (60 mg) can be bought on Amazon. However, if you require 120 mg dose for better results, then you must have written permission for using the medicine,  Xenical, from your medical consultant.

In short: Alli diet pills have various negative points associated with them. They can be the reason for gut problems and deficient nutrients. They may also create problems in absorption of certain medications. The optimal researched dosage quantity is 120 mg, thrice in a day.

Should You Try Alli?

Alli diet pills are one of the few workable pills, showing a limited effect in patients. However, the results are not impressive up to the expectations of users.

These pills can help in losing a little additional weight than the other medications and techniques of weight loss, but for gaining the best results they must be used with a specific low calorie diet and exercise.

Moreover, an analysis of the benefits (i.e. weight loss) and the negative aspects (digestive diseases and nutrient deficiencies) of these pills have to be done before the treatment.

These pills will only be effective if consumed with controlled and low-calorie food that is not tempting for the taste buds and is mostly avoided by food lovers.

Eating more protein and fewer carbs is  a more useful and long term approach to losing weight and keep it off for longer periods.

10 Foods to avoid for weight loss

Woman With Mouthful of ChipsYour diet and food intake can impact your weight to a large degree.

Some foods, such as yogurt with full fat, coconut oil, leafy vegetables and eggs, are best for reducing weight (1, 2, 3).

Other edibles and food items, particularly filtered and processed products can increase your weight.

Below are 10 edibles to stay away from, when you’re striving to reduce weight.

1. Fried Potatoes and Frites

Although, potatoes are flourishing and filling for health, but potato chips and other forms of fried potatoes are abundant in calories, making potato chips unhealthy for diet conscious people. Moreover, they are so tempting that a person eats many of them in one sitting, resulting in weight gain.

According to observational studies, eating Fried Potatoes and Frites can result in weight gains (4, 5).

Interestingly, a research found that Frites can increase more weight than any other eatable (5).

In addition, steamed, roasted, backed or fried potatoes can be a cause of cancer as there are some chances that they can be the carrier of compounds known as acrylamides. Therefore, consuming plain and boiled potatoes are best for the health. (6, 7).

Fried Potatoes and Frites are cause of obesity whereas boiled or steam potatoes are very nourishing.

2. Fizzy Drinks

Glasses With Soda and Ice Cubes

Sugar-sweetened beverages, such as fizzy drinks, are among the most unhealthy foods available.

The consumption of sugary drinks results in increased weights and can destroy the health of people when taken abundantly (8, 9, 10, 11).

Although sugary drinks are full of calories but your brain does not consider them like food that needs to be digested, thus in spite of taking calories you will not feel full and will consume the regular diet too (12).

Thus the calories of liquid sugar will add up in your regular intake of calories resulting in higher amount of calories than usual.

If you really want to lose weight, you will have to leave fizzy drinks entirely.

Fizzy drinks rich in sugar can have negative impact on weight and create other health issues. Giving up sodas and other sugary drinks can make your goal of losing weight easy to achieve.

3. White Bread


White bread is an example of highly refined product. It is made by using added sugar and processed flour.

On the glycemic index, it lies on the higher end and can thrust the glucose level in your blood, immediately (13).

A study consisting of 9,267 participants found that the risk of weight gain and obesity can be increased by 40% if you consume two slices that is approximately 120 g of white bread daily (14).

The traditional white bread have a number of healthy alternatives. One of these alternatives include Ezekiel bread. It is known to be the best bread available for diet conscious people.

All the breads do not contain gluten in them so they can be consumed easily. Some of the other healthy breads include oopsie bread, rye bread,  cornbread, flaxseed bread, and almond flour bread.

A white bread consists of refined flour that has more sugar in it which can also lead to over consumption. However, the number of healthy breads are available in the market.

4. Sweets and Chocolates

Candy bars contain artificial sugar, added oils, taste enhancers, high-calorie chocolates and refined flour that makes these bars extremely unhealthy for consumption especially for the people striving to lose weight.

These bars are rich in calories and low in healthy nutrition. An medium chocolate candy bar can have 200–300 calories in it. The chocolate bars with extra large size may contain a greater number of calories resulting in disturbed diet plans (15).

Candy bars are available every where especially when you are on a diet, you would see these bars where ever you go. In large stores, these bars kept in an eye catching position strategically, so that a large number of customers would by them impulsively

Fruits or dried nuts can be eaten to minimize the craving of these candy bars.

Chocolate bars contains a number of unhealthy ingredients like sugar, refined flour, high-calorie chocolate and added oils. These bars add in calorie in take and are major sources of weight gain.

5. Most Fruit Juices

Orange Juice

The packaged fruit juices that we find generally are not made of whole fruit, most of the times.

These fruit juices contains excessive sugar that can increase your calorie consumption.

Although, it seems that fruit juices must be healthy but the calories and sugar content in packaged juice is generally same as fizzy drinks (16).

In addition, the lack of fiber in fruit juices doesn’t require chewing so it would keep your stomach empty, compelling you to take large servings within a short time.

Moreover, one regular serving of orange juice won’t provide the same benefits as a complete orange (17).

Eating a whole fruit instead of drinking fruit juice is a better option.

Fruit juice contains high calories and are rich in sugar, but lack the fiber. It is better to consume the natural fruit instead of fruit juices.

6. Pastries, Cakes, and Biscuits

Chocolate Chip Cookies

Pastries, cakes and biscuits are rich in artificial sugar and processed flour, which makes them one of the unhealthiest foods to eat.

In some pastries and cookies, artificial trans fats are also present. These trans fats can be the cause of a number of health problems (18).

Pastries, cakes and biscuits do not satisfy your stomach for a long time. You will start to feel hungry again in no time after having such stuff with more calories and low nutrient value.

If you like to eat something sweet, go for a  chunk of dark chocolate.

Pastries, cakes and biscuits are full of artificial sugar, processed flour and trans fat. Such eatables are responsible for weight gains but do not satisfy the stomach.

7. Some Types of Alcohol (Especially Beer)

Glass of Beer

Alcohol contains a greater number of calories than the average diet rich in carbs and protein. Per gram of alcohol contains more than 7 calories.

However, the alcohol has not been a proved cause of affecting the weight, up till now (19).

Having alcohol in moderate quantities are associated to lesser weight gains whereas heavy drinking is linked with more weight gain (20, 21).

The calorie in take is also dependent on the kind of alcohol being used. Beer can increase the weight whereas consuming wine in moderate quantities may be beneficial for weight loss (19, 22).

If losing weight is your aim, then you should say ‘no’ to alcohol. However, wine in smaller servings can be consumed.

8. Pizza

Cringing Woman Saying No To Pizza

Pizza is an extremely tasty and a well known fast food but pizzas are very high in calories that makes them a bad choice for dieters.

They contain a large number of calories and are made by using unhealthy components such as processed flour, high-fat cheese and processed meat.

A home-made pizza with healthier ingredients can be one of the alternatives of the conventional commercial pizzas. In addition, the sauces used in the pizzas can also be made at home, which would make pizzas more healthier than their super-market versions.

Another solution for the pizza craving is to find a pizza parlor that serves healthier and low-calorie pizzas.

Traditional pizzas sold in stores contains high calorie ingredients like refined flour and sugar. A pizza made at home can be a healthier alternative.

10. High-Calorie Coffee Drinks


Coffee can be among one of the drinks that can be consumed for reducing weight. It contains caffeine that can help in reducing the excessive fats from the body.

Caffeine helps to boost your metabolism that increases the fat burning process in the body, instantly (23, 24).

Apart from it, coffee can also result in weight gains if unhealthy constituents like cream and added sugar are excessively used.

The coffee drinks, rich in calories have similar effects as soda. They contain a large number of calories, which can have disastrous effects on your health.

If you are a coffee lover but trying to lose weight, then it’s best to consume simple black coffee. Using some cream or milk will work but adding sugar and other high-calorie ingredients will spoil your diet.

Plain and simple black coffee can be a healthy option to increase your metabolism but adding unhealthy ingredients in it to make it tasty will ruin your weight loss efforts.

11. Foods High in Artificial or added Sugar

Granola Bars

Added sugar can have worsening effects on your body. These added sugars have been associated with the most harmful diseases known (25, 26, 27).

Foods, which are rich in artificial sugar, adds to the calorie in take but does not satisfy the stomach.

Some of the examples of food that contain large quantities of added sugar include breakfast cereals, salad dressing, granola bars, tomato sauce and flavored yogurt.

You should carefully select the “low-fat” or “fat-free” food because it might contain added sugar to compensate for the lost flavors.

Here you can find 15 “health foods” that are really just junk foods in disguise.

Additional sugar is unhealthy ingredient that is used in a number of edibles. Many edibles like fat-free foods, seem healthful but can contain massive sugar contents.

Lessons Learned

Some of the foods that are not suitable for consumption in losing weight are made from highly processed and refined ingredients. These foods are particularly full of additional sugar content and other unhealthy substances that increases the calorie intake.

If you’re unsure about the nutrients in a food, read the label but you must be careful with different names for sugar that can be misleading.

Additionally, it is also important to have a close look on the quantity of food taken. Some healthy foods, like nuts, dried fruit, full cream milk and cheese, are rich in calories, and can be consumed in large quantities.

How many Carbs should YOU eat for Weight Loss

Cutting down on carbohydrates can help you lose weight fast.

It can be easier than the strict portion control and counting calories, which many people find hard to maintain.

Reducing the amount of carbs in your diet can reduce your cravings for food and automatically help you lose weight.

What is a Low-Carb Diet?

There are lots of diet fads out there. For decades, so-called health authorities have suggested that you eat a low-fat, low-calorie diet in order to lose weight. That might sound like a great diet plan, but people rarely stick to it. (1, 2, 3)

A more effective solution is the low carbohydrate diet. If you cut down on sugary foods and starches such as breads, rice and pastas, and replace them with veggies, meats and fats, then you will see lasting results.


Researchers for Duke University Medical found that a low-carb diet stimulates your body’s urge to stop eating. When you feel full, you consume less calories and shed more weight.(4)

When compared to low-fat diets, low-carb diets tend to be more effective without the need to actively restrict caloric intake.(5, 6).

Low carbohydrate diets aren’t just for weight loss either. Some auxiliary benefits include a rise in good cholesterol (HDL) and lower blood sugar, triglycerides, lower blood pressure and lower levels of bad cholesterol, so-called LDH. (7, 8, 9, 10).

The science is clear. Low-carb diets improve overall health and stimulate weight loss. This is superior to calorie-restricted, low-fat and low-protein diets that are so popular in the mainstream media. (11, 12, 13).

Conclusion: Scientific studies support the value of low-carb diets over trendy, low-fat diets.

Figuring Out Your Optimum Carbohydrate Level

A person’s ideal caloric and carbohydrate level varies from person to person. Some influential factors include a person’s body type, age, gender and metabolism.

So it’s difficult to set a generalized benchmark of what makes up a low-carb diet.

Metabolic health is key. Obesity, Type 2 diabetes, and lack of exercise are the greatest determining factors of how much carbohydrate-rich foods are normal in a day.

Generally speaking, people who exercise more can tolerate more carbohydrates. People who live a more sedentary life will have a more difficult time processing carbohydrates.

Conclusion: The “perfect” carbohydrate level doesn’t exist. It depends on the person’s lifestyle, health conditions and body type.

Effective Plans for Different Activity Levels

Your first step to losing weight with a low-carb diet is to reduce or eliminate sugary foods and wheat (gluten). That’s just the beginning. Start slow and work your way up.

A good starting point for how many carbs you should try and stay under are:

100-150 Grams A Day
If you lead an active lifestyle or just need moderate results, then reduce your intake to the range of 100-150 grams a day.

Your optimum diet consists of all types of veggies and several servings of fruit. You can also eat some healthy starches such as potatoes, oats and rice as long as you control the portions.

50-100 Grams A Day
This level is great for people who have already seen great weight loss and want to keep the weight off.

Your optimum diet consists of several servings of vegetables and fruits per day.

To maintain your weight loss goals reduce your starchy carbohydrates to a minimum.

20-50 Grams A DayCouch_potato

If your goal is to lose weight fast,  but you aren’t very active or exercising regularity, then this is the level for you.

Eating less than 50 grams of carbs a day triggers ketosis, a metabolic response that will reduce your appetite and help you automatically feel full.

Be sure to eat low-carb veggies and fruits such as carrots and berries. You can also supplement your carb intake with walnuts, pecans, and sunflower seeds.

Everybody is Different

Don’t forget that everybody is different. Try new foods and experiment with new recipes to find out what level is right for you. Be sure to drink plenty of water during this process and consult your doctor before starting any new diet or workout routine.

Conclusion: With regular exercise, a range of 100-150 grams a day works best for healthy individuals. For people who need to see faster results, drop your carbohydrate intake below 50 grams.

Good Carbs vs. Bad Carbs

carbs - good and bad

Just because you choose a low-carb diet doesn’t mean all carbs are created equal. Be sure to choose healthy, unprocessed foods and stay away from low-carb junk food.

So what are good carbs? lean protein-rich meats like chicken and fish, eggs, nuts, and legumes are some good examples.

What are bad carbs? Refined grains like pizza crust, pretzels, and potato chips.

For more information on specific foods, check out this detailed low-carb meal plan and sample menu.

Conclusion: Be selective. Eat fiber-rich, whole foods whenever possible and avoid the junk food that is devoid of nutritional value.

You Can Be A Fat-Burning Machine

Insulin is an important component to your weight loss equation. It’s a hormone that stores fat in your body. One of the benefits of a low-carb diet is its ability to lower the levels of insulin in your blood, thereby reducing the fat.

Insulin also regulates the amount of sodium retained in the kidneys. A low-carb diet cuts back on the insulin your body produces and you can start to see lots of water weight reduction in the first week. (14, 15).

In a study that examined body composition, researchers found that low-carb dieting can slow the effects of aging as well as increase muscle mass and help dieters lose large amounts of body fat.(17)

When it comes to targeted weight loss, research shows that low-carb diets are especially effective at reducing that stubborn belly fat around the abdominal cavity that is so hard to get rid of.

Conclusion: Burning fat has more to do with body chemistry than exercise alone. Targeting specific hormones and problem areas will help you see results faster.

The Bottom Line

A low-carb diet is simple and effective. There are several tools to help you, as well, like this Free Carb Tracker App

Be sure to focus on net carbohydrates because grams of fiber don’t count toward your total carb intake.

You can start your low-carb diet by simply eating healthy proteins, fats, fruits and vegetables with every meal. Avoid processed foods and supplement your diet with walnuts, seeds and full-fat dairy products.
