Lipozene is a popular diet pill for weight loss. It contains a soluble fiber called glucomannan that absorbs water to create a thick gel. This fiber may be responsible for many of the benefits of the supplement that people report.
Lipozene may have potential benefits in some cases. However, the weight loss effects are usually mild, and it is not right for everyone.
Diet pills, such as Lipozene, are not replacements for proven weight control methods, such as eating a healthy diet and exercising regularly.
This article explores the safety of Lipozene, as well as its benefits, side effects, and effectiveness.
The konjac root and its compounds are also popular weight loss aids because of this fiber and its ability to absorb water.
The soluble fiber glucomannan, which is the active ingredient in Lipozene, is safe when people use it as the manufacturers direct.
Importantly, the fiber absorbs many times its weight in water, so it is essential to stay hydrated.
This requirement means drinking plenty of fluids while using any products that contain konjac fiber.
The benefits of glucomannan relate to its specific type of soluble, fermentable dietary fiber.
A review in the International Journal of Biological Macromolecules notes that glucomannan fiber may help:
- reduce levels of glucose
- reduce cholesterol
- reduce fats in the blood
- lower blood pressure
- help enable weight loss
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 look at some specific potential benefits in more detail.
It may 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.
Because of this, a person who takes Lipozene may
It may reduce calories from meals
As glucomannan can make the body feel fuller, it might reduce the number of calories a person eats with each meal. If the person consumes fewer calories than they burn each day, this could lead to weight loss over time.
The fiber itself is also low in calories, so taking it does not add much to the diet.
It may reduce caloric intake from other sources
Glucomannan may also help a person lose weight by reducing the energy they absorb. Soluble fibers, such as glucomannan, may reduce the
This means that the body might take up less energy from these food sources and, instead, pass these calories out with waste.
It is a source of prebiotic fiber
Glucomannan fiber is also prebiotic. This means that it feeds the healthy bacteria that colonize the intestines.
The International Journal of Biological Macromolecules review notes that the stomach does not digest the fiber. Instead, the fiber passes through to the intestines, where the intestinal bacteria can ferment it and use it as fuel.
This process is important, as the health of the intestinal 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
- decrease allergy risk
- cut the harmful fermentation of proteins in the gut
- improve the immune system response
Although not every prebiotic fiber will act the same way, eating a diet rich that is in prebiotics may help ensure that the intestinal flora are healthy.
It has 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.
So, the product may be an option for people looking for more straightforward ingredients to help them with weight loss.
Most people tolerate glucomannan well. However, some people may be more sensitive to soluble fibers, and mild reactions in the digestive system may occur.
Some side effects may be worse if the person does not drink enough water along with the glucomannan, as the fiber is highly absorbent and may take water from the body.
Glucomannan may also reduce the absorption of certain medications. A person can talk with a doctor before taking Lipozene to ensure that it will not interact with any of their medications.
The following sections look at some specific risks in more detail.
There is a risk of choking if an individual does not drink enough water along with Lipozene capsules. Specifically, if the capsules become stuck in the throat, they may expand and swell, blocking the esophagus.
For this reason, people who have difficulty swallowing capsules may want to avoid Lipozene.
Reactions from other ingredients
Although glucomannan and konjac root are not common allergens, some people may be more sensitive to the added ingredients in Lipozene.
Aside from glucomannan from the konjac root, Lipozene capsules also contain:
- microcrystalline cellulose
- magnesium silicate
- stearic acid
- titanium dioxide
- FD&C Blue #1
Typically, the effectiveness of Lipozene for weight loss is mild. A review in Current Obesity Reports notes a broad body of research, including nine clinical trials, suggesting that glucomannan may be mildly effective for weight loss.
The researchers note weight loss of 0.5–1.7 pounds after taking glucomannan for 5.2 weeks.
However, an older
For some people, these mixed results may be enough to justify taking Lipozene to boost their diet and weight loss goals. Other people may feel they do not justify the cost.
The Lipozene website recommends taking two capsules and a full glass of water 30 minutes before each meal, up to six capsules each day.
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 publishing, Lipozene costs $29.95.
The manufacturer charges a processing fee of $1.35 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 happy with the effects of the supplement within 30 days of receiving their order, the manufacturer will refund the money minus a processing fee of $1.35.
Taking glucomannan or Lizopene for weight loss appears to produce mild results in some cases. However, no dietary supplement is a replacement for other healthy weight loss habits.
Anyone who is looking to lose weight will still need to make changes to their diet and lifestyle. These changes often include eating a healthy diet, reducing caloric intake, and getting regular exercise.
Anyone who is worried about their weight should work with a doctor to create an individualized plan for weight loss.
People who are looking to lose weight may wish to change their diet and engage in more physical activity. The sections below cover these lifestyle changes in more detail.
People should ensure that they are eating a healthy, balanced diet if they wish 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 greens and starchy vegetables
- whole fruits
- grains, half of which should be whole grain
- dairy, 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 food they eat with high sodium, added sugars, and saturated fats.
Meal kit deliveries
Although people can meal plan and cook food in batches to eat throughout the week, others may prefer to use meal kit delivery services that offer food that may help people lose weight.
Some meal kit delivery services that may offer calorie-conscious meals include:
- Blue Apron: This company offers low calorie, carbohydrate-conscious, and diabetes-friendly meals. Blue Apron also sells meals that contain 600 calories or fewer. Learn more about Blue Apron here.
- Trifecta: This company offers meals that contain 350–500 calories, which may help support weight loss. Trifecta uses organic ingredients and has meals suitable for people with ketogenic, paleo, and plant-based diets. Learn more about Trifecta here.
- Factor: This company states that most of its meals contain around 600 calories. Factor has meals that are suitable for people with various diets, such as low calorie, high protein, and plant-based. Learn more about Factor here.
People should also engage in regular physical activity to lose or maintain weight.
People should aim for 150 minutes of moderate-intensity cardio, 75 minutes of vigorous-intensity cardio, or a combination of the two per week. Getting this amount of activity can help people maintain weight loss and lose weight while eating a healthy diet.
Lipozene is a well-reviewed dietary supplement. The active ingredient, called glucomannan, is a natural fiber that may 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, though any additional weight loss resulting from the supplement is typically mild.
