Abstract

Insights

Neoagaro-oligosaccharides (NAOs) significantly reduced visceral fat and suppressed weight gain in overweight individuals. This study suggests NAOs are a safe and effective anti-obesity supplement without adverse effects.

Area of Science:

  • Nutrition Science
  • Human Physiology
  • Clinical Research

Background:

  • Obesity is a growing global health concern requiring effective interventions.
  • Neoagaro-oligosaccharides (NAOs) are novel compounds with potential anti-obesity properties.
  • A randomized, double-blind, placebo-controlled trial was conducted to assess NAO efficacy and safety.

Purpose of the Study:

  • To evaluate the anti-obesity effects of Neoagaro-oligosaccharides (NAOs) in overweight or obese humans.
  • To assess the safety profile of NAOs during a 16-week intervention period.
  • To determine the impact of NAOs on key metabolic and body composition markers.

Main Methods:

  • 100 overweight/obese participants (BMI 23–34.9 kg/m², body fat >25% males/>30% females) were enrolled.
  • Participants received either 3g of NAOs twice daily or a placebo for 16 weeks.
  • Efficacy and safety biomarkers, including body composition and blood lipids, were measured pre- and post-intervention.

Main Results:

  • NAOs significantly decreased visceral fat area and the visceral-to-subcutaneous fat ratio compared to placebo.
  • The NAO group showed suppressed weight and BMI increases, with significant between-group differences.
  • High-density lipoprotein-cholesterol increased in the NAO group, with a significant trend observed.
  • No adverse clinical changes were noted in safety biomarkers for the NAO group.

Conclusions:

  • NAOs demonstrate a beneficial effect in combating obesity.
  • NAOs can be considered a safe and effective supplement for weight management.
  • Further research may explore long-term effects and optimal dosing of NAOs.

Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Oral Hypoglycemic Agents: Biguanides and Glitazones01:26

Oral Hypoglycemic Agents: Biguanides and Glitazones

Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are...

Gastric Emptying01:16

Gastric Emptying

Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Regulation of Food Intake01:30

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents

Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.
