Lipozene is a popular diet pill for weight loss. It contains a soluble fiber called glucomannan which absorbs water to create a thick gel. This fiber may be responsible for many of the benefits of the supplement reported by people.

Lipozene may have potential benefits in some cases. However, the effects of weight loss are generally mild and not for everyone.

Diet pills, such as Lipozene, are not a substitute for proven methods of weight control, such as healthy eating and regular physical activity.

This article explores the safety of Lipozene, as well as its benefits, side effects, and effectiveness.

The soluble fiber glucomannan, which is the active ingredient in Lipozene, is safe when people use it according to the manufacturers’ instructions.

Importantly, fiber absorbs many times its weight in water, so staying hydrated is essential.

This requirement means drinking plenty of fluids while using products containing konjac fiber.

The benefits of glucomannan are related to its specific type of soluble and fermentable dietary fiber.

A review in the International Journal of Biological Macromolecules notes that glucomannan fiber may help:

Many of these benefits come from how glucomannan behaves in the body. Glucomannan absorbs many times its weight in water, forming a gel-like substance that the digestive system processes with food.

The sections below examine some specific potential benefits in more detail.

He can keep the body full

Taking Lipozene with a full glass of water before each meal creates a thick, gel-like substance in the stomach. This substance leaves less room in the stomach for food.

For this reason, a person taking Lipozene may feel full soonerwhich can reduce the risk of overeating.

It can reduce meal calories

As glucomannan can make the body feel more full, it can reduce the number of calories a person consumes at each meal. If the person is consuming fewer calories than they are burning each day, this could lead to weight loss over time.

Fiber itself is also low in calories, so taking it doesn’t add much to the diet.

It can reduce calorie intake from other sources

Glucomannan can also help a person lose weight by reducing the energy they absorb. Soluble fiber, such as glucomannan, can reduce absorption nutrients, such as fats.

This means that the body could absorb less energy from these food sources and instead expel these calories as waste.

It is a source of prebiotic fiber

Glucomannan fiber is also prebiotic. This means it feeds the healthy bacteria that colonize the intestines.

the International Journal of Biological Macromolecules the examination notes that the stomach does not digest the fibres. Instead, the fiber passes through the intestines, where gut bacteria can ferment it and use it as fuel.

This process is important because the health of gut microorganisms influences the overall well-being of the body.

A study in Current developments in nutrition notes the benefits of prebiotic compounds, including their ability to:

  • increase healthy bacteria in the intestines
  • increase mineral absorption
  • decrease harmful bacteria in the gut
  • reduce the risk of allergy
  • cut off harmful protein fermentation in the gut
  • improve immune system response

Although not all prebiotic fiber works the same way, a diet rich in prebiotics can help support healthy gut flora.

It contains simple active ingredients

Another potential benefit is that Lipozene is a relatively simple form of weight loss supplement.

Although some pills may contain stimulants, laxatives or other additives, the only active ingredient in Lipozene is glucomannan.

Thus, the product may be an option for people looking for simpler ingredients to help them lose weight.

Most people tolerate glucomannan well. However, some people may be more sensitive to soluble fiber and mild reactions in the digestive system may occur.

Benign Side effects of taking glucomannan may include:

Some side effects may be worse if the person does not drink enough water with glucomannan, as the fiber is very absorbent and can absorb water from the body.

Glucomannan can also reduce the absorption of certain medications. A person can speak with a doctor before taking Lipozene to make sure it will not interact with any of their medications.

The following sections examine some specific risks in more detail.


There is a choking hazard if an individual does not drink enough water with Lipozene capsules. Specifically, if the capsules get stuck in the throat, they can expand and swell, blocking the esophagus.

For this reason, people who have difficulty swallowing capsules may want to avoid Lipozene.

Anyone who experiences serious side effects — such as chest pain, difficulty breathing, or trouble swallowing — after taking Lipozene should seek immediate medical attention.

Reactions of other ingredients

Although glucomannan and konjac root are not common allergens, some people may be more sensitive to the ingredients added to Lipozene.

Besides glucomannan from konjac root, Lipozene capsules also contain:

  • Gelatin
  • microcrystalline cellulose
  • magnesium silicate
  • stearic acid
  • titanium dioxide
  • FD&C Blue #1

Generally, the effectiveness of Lipozene for weight loss is mild. A review in Current Obesity Reports notes a large body of research, including nine clinical trials, suggesting that glucomannan may be marginally effective for weight loss.

Researchers note a weight loss of 0.5 to 1.7 pounds after taking glucomannan for 5.2 weeks.

However, an older 2013 study suggests that glucomannan does not promote weight loss, alter body composition, or alter feelings of hunger or fullness.

For some people, these mixed results may be enough to justify taking Lipozene to boost their diet and weight loss goals. Other people may think they don’t justify the cost.

the Lipozene website recommends taking two capsules and a large glass of water 30 minutes before each meal, up to six capsules per day.

Dosage recommendation

A two-capsule serving of Lipozene contains 1,500 milligrams of konjac fiber. This serving should always include at least 8 ounces of water.

At the time of publication, Lipozene costs $29.95.

The manufacturer charges a $1.35 handling fee when shipping the item. Additionally, the manufacturer will charge a fee of $1.35 if a person returns the supplement.

There is a 30 day money back guarantee. If a person is not satisfied with the effects of the supplement within 30 days of receiving their order, the manufacturer will refund the money less a $1.35 processing fee.

Taking glucomannan or lizopene for weight loss seems to produce mild results in some cases. However, no dietary supplement replaces other healthy weight loss habits.

Anyone looking to lose weight will still need to make changes to their diet and lifestyle. These changes often include healthy eating, reduced calorie intake, and regular physical activity.

Anyone concerned about their weight should work with a doctor to create an individualized weight loss plan.

People looking to lose weight may want to change their diet and get more physical activity. The sections below cover these lifestyle changes in more detail.

Balanced diet

People need to make sure they have a healthy, balanced diet if they want to manage their weight.

Each individual will need a slightly different number of calories per day to maintain, gain or lose weight. The United States Department of Agriculture (USDA) has a free tool on its website that people can use to find out their calorie needs.

the Dietary Guidelines for Americans 2020-2025 recommend people eat the following for a healthy, balanced diet:

  • all types of vegetables, including leafy and starchy vegetables
  • whole fruit
  • grains, half of which should be whole grains
  • dairy products, including fat-free, low-fat, lactose-free, and soy milk, yogurt, and cheese
  • protein, such as lean meat, poultry, legumes, and soy products
  • oils, such as vegetable oils

People should limit the amount of foods they eat that are high in sodium, added sugars, and saturated fat.

Meal kit deliveries

Although people can plan their meals and cook foods in batches to eat throughout the week, others may prefer to use meal kit delivery services that offer foods that can help people lose weight. .

Some meal kit delivery services that may offer low-calorie meals include:

  • blue apron: This company offers low-calorie, carb-conscious, diabetes-friendly meals. Blue Apron also sells meals with 600 calories or less. Read more about the blue apron here.
  • Trifecta: This company offers meals with 350 to 500 calories, which can help promote weight loss. Trifecta uses organic ingredients and offers meals suitable for people following a ketogenic, paleo and plant-based diet. Learn more about Trifecta here.
  • Factor: This company states that most of its meals contain around 600 calories. Factor offers meals suitable for people with a variety of diets, such as low-calorie, high-protein, and plant-based. Learn more about Factor here.

Physical activity

People should also engage in regular physical activity to lose or maintain weight.

the Centers for Disease Control and Prevention (CDC) say people shouldn’t rely solely on physical activity to lose weight. A combination of eating healthy foods and exercising regularly is more likely to help a person achieve their health goals.

People should aim for 150 minutes of moderate-intensity cardio, 75 minutes of vigorous-intensity cardio, or a combination of both per week. Getting that much activity can help people maintain weight loss and lose weight while eating healthy.

Lipozene is a well-reviewed dietary supplement. The active ingredient, called glucomannan, is a natural fiber that can benefit the body when a person takes it regularly with plenty of water.

No supplement can replace dietary and lifestyle changes for weight loss. Taking Lipozene may help support weight loss efforts for some people, although any additional weight loss from the supplement is usually mild.
