How Does Chitosan Work for Weight Management?

To fully appreciate chitosan's role in weight management, it's essential to understand its nature and origins.

Chitosan is a natural biopolymer derived from chitin - the second most abundant polysaccharide in nature after cellulose. Chitin is found in the hard outer shells of crustaceans and certain fungi cell walls.

Extracting chitosan involves deacetylation that removes acetyl groups from chitin, leaving free amino groups behind. A high degree of deacetylation (DD) means more free amino groups to enhance chitosan's remarkable properties and bioactivities:

• Non-toxic
• Biocompatible
• Biodegradable
• Antimicrobial
• Antioxidant
• Anti-inflammatory
• Anti-diabetic
• Hypolipidemic
• Gut microbiota modulating

These properties make chitosan particularly valuable for supplement formulators, with the global chitosan market soaring past $1 billion in 2022.

Chitosan's unique properties and natural origin make it ideal for consumers seeking natural health care options. As a dietary supplement, chitosan slows digestion and reduces the fat the body absorbs from foods.

Chitosan binds to lipids in the gastrointestinal tract, decreasing absorption and lowering body weight and cholesterol. This fat-blocking ability makes it ideal for weight management.

Chitosan aids in weight management through its multifaceted properties to support healthy weight loss. Here is how it works:

1) Fat Binding and Reduced Absorption

Chitosan is a natural fiber with remarkable fat-binding qualities due to its positive charge and gel-forming ability. The gel actively absorbs oils, fats, and lipids to inhibit dietary fat metabolism. It works as follows:

• Gel Formation: In the stomach's acidic environment, chitosan forms a positively charged gel.
• Binding to Fats: This gel binds to negatively charged dietary fats and cholesterol.
• Preventing Absorption: By binding to fats, chitosan prevents their absorption into the bloodstream, which helps reduce overall calorie intake and contributes to weight loss.
• Excretion of Bound Fats: The bound fats are excreted rather than absorbed, reducing calorie intake.
• Cholesterol Lowering: Chitosan lowers cholesterol by bonding with cholesterol and other fats, interfering with their emulsification and breakdown. These large, bonded compounds are then not easily digested.

Scientific evidence supports chitosan's fat-binding capacity. In vitro studies demonstrate that chitosan can bind 4-5 times its weight in fat (Nauss et al., 1983). Its positive charge gives it a higher fat-binding capacity than other fibers, making chitosan a powerful tool for weight management.

2) Increased Satiety

Beyond its fat-binding properties, chitosan contributes to weight management by increasing satiety – the feeling of fullness after eating. As a fiber, chitosan slows gastric emptying, meaning food takes longer to leave the stomach. This prolonged gastric emptying can help people feel fuller for longer, potentially aiding portion control and reducing calorie intake.

One study (Egan et al., 2016) investigated the appetite-suppressing potential of chitosan in a pig model. The findings were significant:

• Pigs fed a chitosan-supplemented diet had fewer feeder visits per day.
• They consumed less feed per visit and spent less time eating daily.
• The chitosan-fed pigs exhibited a slower eating rate and reduced overall feed intake.
• They maintained a 6kg lower body weight than the control group.

Also, the chitosan-fed pigs exhibited changes in:

• Serum Leptin Concentrations: Indicating alterations in appetite regulation.
• Gene Expression: Related to appetite regulation, suggesting that chitosan alters feeding behavior and enhances satiety signals in vivo.

Multiple animal and clinical trials have demonstrated that chitosan improves gut microbiota, restores intestinal barrier function, and regulates thermogenesis and lipid metabolism. These combined effects support chitosan's role in promoting satiety and aiding weight management.

3) Supporting Digestion

The gut microbiota directly affects nutrient absorption and fat accumulation in the human intestine. Disturbances in gut microbiota are closely related to obesity and associated metabolic syndromes.

Prebiotics are food for gut microbiota and improve the balance of these microorganisms. Chitosan is a prebiotic with significant gut health benefits that indirectly support weight management.

Here's how chitosan impacts gut bacteria:

• Enhances Beneficial Bacteria: Promotes Bifidobacteria and Lactobacillus growth, aiding digestion and improving nutrient absorption.
• Reduces Harmful Bacteria: Decreases harmful bacteria like Staphylococcus aureus and Enterobacteria, improving overall gut health.
• Improves Gut Health in Obese Individuals: Increases the presence of weight-reducing bacteria such as Coprobacillus cateniformis and Clostridium leptum, which help break down complex carbohydrates and reduce fat storage.
• Regulates Glucose-Related Bacteria in Diabetics: Helps manage blood sugar by influencing bacteria involved in glucose metabolism.
• Reduces Gut Inflammation: Chitosan reduces the chronic inflammation caused by high-fat diet consumption. It strengthens the gut barrier by increasing the production of tight junction proteins that improve the connections between gut lining cells. This decreases harmful bacteria-induced inflammation.
• Enhances SCFA Production: Increases short-chain fatty acids (SCFA) production, improving insulin sensitivity and reducing inflammation.

Gut bacteria enhance nutrient absorption, boost the immune response, and support metabolic processes. Chitosan's ability to balance gut bacteria is crucial for overall health and weight management.

Chitosan, which has been proven to be safe for humans, provides a safer alternative to stimulant-based weight loss products, which are increasingly recognized as dangerous.

While weight management is a primary benefit of chitosan supplementation, medical studies show it may help general health. For instance, beta-glucans have positive results in protecting the cardiovascular system. This is due to all of the following reasons:

1. Cholesterol Reduction: Lowers LDL (bad) cholesterol and total cholesterol levels.
2. Blood Pressure Management: Aids in reducing both systolic and diastolic blood pressure.
3. Glucose Control: Decreases fasting glucose levels, which is particularly beneficial for individuals at risk of or managing diabetes.
4. Inflammation Reduction: Significantly lowers hs-CRP, a marker of inflammation in the body.
5. Reduction in Atherosclerotic plaque: Beta-glucan can reduce both the size and secretion levels of atherosclerotic plaques in arteries.
6. Oxidative Stress Reduction: By reducing free radicals, oxidative stress levels drop.

Fungal Chitosan for Weight Management

A 90-day clinical trial on fungal chitosan (500 mg, 5 capsules/day) showed significant benefits for weight management:

• Weight Loss: Participants lost 1.78 kg by day 45 and 3.10 kg by day 90.
• BMI Reduction: 10.91 times greater than placebo after 90 days.
• Body Composition: Significant reduction in body fat, visceral fat, and waist circumference.
• Blood Sugar Control: HbA1C levels reduced to below 6% in at-risk individuals
• Quality of Life: Enhanced SF-36 questionnaire scores indicate improved overall well-being.
• Safety: Well-tolerated with only mild, unrelated adverse events.

This study underscores the effectiveness of fungal chitosan in promoting weight loss of up to 3 kg and improving overall health markers without dietary restrictions.

Long-Term Effects: Polyglucosamine (PG L112) Study

A 12-month study evaluated the efficacy of polyglucosamine (PG L112), a low-MW chitosan used with ascorbic and tartaric acids, versus a placebo in overweight and obese individuals (BMI 30-35). Participants were advised to reduce caloric intake by 10% and increase physical activity (Cornelli et al., 2017).

Polyglucosamine (PG) was more effective than placebo (PL) in:

• Weight Loss: The PG group lost 12.1 kg (12.7% reduction) compared to 8.0 kg (8.4% reduction) in the placebo group.
• Waist Circumference: Reduced by 13.3 cm in the PG group versus 10.2 cm in the placebo group.
• Blood Pressure: Both diastolic and systolic blood pressure showed more significant reductions in the PG group.
• Lipid Profile: Total cholesterol, LDL cholesterol, and triglycerides significantly decreased in the PG group.
• Glucose Levels: The PG group saw an 8.9% reduction compared to 4.1% in the placebo group.
• Inflammation: hs-CRP levels were reduced by 58.3% in the PG group versus 40.6% in the placebo group.

These results support the efficacy of chitosan-derived products for long-term weight management and metabolic improvements.
