How Psyllium Husk Aids Weight Loss

Psyllium husk aids weight loss by pushing the body toward the fat loss phase and improving various body functions.

The psyllium plant is mainly grown in India, Bangladesh, and Pakistan and is known as isabgol (Persian: asp – horse and gul – flower). The seeds have been used in traditional Iranian medicine since ages. Psyllium husk is a good source of fatty acids and starch and is used as an additive in animal feed as well.

How does psyllium husk aid weight loss? Here are 6 scientific ways:

1. Increases Satiety

A study by American scientists shows that psyllium husk aids greater satiety and reduces hunger pangs (2). Psyllium contains soluble dietary fiber, which forms a gel-like layer after coming in contact with water. This layer helps slow down the transit of food through the stomach, resulting in increased satiety (3).

Psyllium husk helps in curbing your appetite without affecting the energy levels. This aids weight loss.

2. Acts As A Laxative

In a study published in Current Medical Research and Opinion, scientists found that psyllium husk to be the most efficient laxative. It helped treat constipation and reduced abdominal pain and diarrhea better than other laxatives (4).

Psyllium is a home remedy for constipation. The fiber helps draw water from the body and adds bulk to the stool, thereby improving gut movement (5). This helps in building a strong immune system and effectively helps in losing weight. Here are some more high fiber foods for weight loss.

3. Improves Lipid Profile

Researchers from New Zealand conducted a study on 47 15-16-year-old participants. The participants consumed 6 g of psyllium husk for six weeks. Their body composition, insulin sensitivity, lipid profile, and blood pressure were measured. The fiber in the psyllium husk reduced bad (LDL) cholesterol and fat (by 4%) in the participants (6).

4. Reduces Cholesterol

Scientists at the Washington State University experimented with seven participants. They were on 21 g/day psyllium husk supplementation for three weeks. By the end of the third week, the total cholesterol was considerably low (7). Psyllium husk may also be effective in lowering cholesterol in postmenopausal women (8).

5. Improves Glucose Homeostasis

The soluble fiber present in the psyllium husk not only increases satiety but also improves glucose homeostasis. In a study, type 2 diabetes patients were supplemented with psyllium husk for eight weeks, which improved their insulin levels, glucose tolerance, and metabolism (9).

6. Lowers Blood Glucose

Psyllium husk also helps lower blood glucose levels by increasing satiety levels. A study published in the British Medical Journal showed that due to the slowing down of the transit time of the food, the blood glucose levels did not rise suddenly after a meal (10).

7. Helps Treat Metabolic Syndrome

According to scientists Supreeya Swaroop and Roman Zeltser, “Metabolic syndrome is an accumulation of several disorders, which together raise the risk of an individual developing atherosclerotic cardiovascular disease, insulin resistance, and diabetes mellitus, and vascular and neurological complications such as a cerebrovascular accident.” (11)

A study published in the Journal of Clinical Gastroenterology shows that psyllium intake helps lower bad cholesterol, improves triglyceride levels and satiety, reduces blood pressure, and aids weight loss. All of these, together, help treat metabolic syndrome (12).

These are the seven ways in which psyllium husk aids weight loss. But how to take it? Find out in the next section.
