In the fast-paced era, staying up late, lack of exercise, and eating takeaways have become the three major habits of young people's lives. The problems of heavy oil and salt, drinking alcohol, and heavy sugar addiction are common among adults of different ages, and these bad habits can lead to obesity more or less. Losing weight has become an urgent need for adults of different ages.
The plant extract industry has many raw materials with weight loss effects. The following extracts are mainly introduced:
1. Gymnema Sylvestre: Also known as Gymnema Sylvestre, a perennial woody climbing dicotyledon, mainly distributed in south-central India and southern China.
2. Mulberry leaf extract. It is made from mulberry leaf (Morus alba L.) through water extraction, microfiltration, ultrafiltration, spray drying, and other processes. It contains mulberry leaf flavonoids, mulberry leaf Polyphenols, mulberry leaf polysaccharides, alkaloids, and other physiologically active substances.
3. White Kidney Bean Extract, also known as multiflora bean, originated in Mexico and Argentina in the Americas and was introduced and cultivated in China at the end of the 16th century. White kidney bean extract contains relatively high activity α- Amylase inhibitors.
4. Garcinia cambogia extract is native to Southeast Asia, also known as Malabar tamarind. Garcinia cambogia extract is prepared from the dried fruit or dried peel of Garcinia cambogia. The main active ingredients are Hydroxycitric acid.
5. Resistant Dextrin is a kind of dietary fiber prepared from edible starch through dextrinization reaction under acidic conditions, with good acidity, thermal stability, high digestive tolerance, low Glycemic index, and low insulin index.
How do these ingredients work for weight loss?
1. Gymnemic acid (gymnemic acid) in gymnastic leaves has the effect of blocking sweet taste buds and can temporarily suppress the tongue's ability to perceive sweetness. Experiments found that in addition to temporarily reducing the perception of sweetness, subjects who ingested Gymnema leaf extract also had reduced cravings for sweets and were more likely to limit food intake during a subsequent meal compared to those who did not.
In addition, studies have also found that taking Gymnema leaf extract significantly reduces appetite and consumes fewer calories. The acidic compounds in Gymnastics leaves can also bind to receptors on the intestinal wall, greatly reducing the absorption of sugar molecules.
The active ingredient DNJ (1-deoxynojirimycin) in mulberry leaf extract can inhibit the effect of α-glucosidase on sucrose and carbohydrates, inhibit the absorption of carbohydrates in the small intestine, and achieve the purpose of reducing postprandial blood sugar.
2. White kidney bean extract contains highly active α-amylase inhibitors, which can play the best role in the pH range of 4.5~5.5 and the temperature range of 22~37 °C. Some studies have pointed out that, it can interact with α-amylase produced by the pancreas at the active site, and competitively inhibit the combination of α-amylase and starch, thereby slowing down the digestion and absorption of carbohydrates by the body. In addition, white kidney beans are particularly satiating and can reduce the intake of other foods.
Garcinia Cambogia Extract Hydroxycitric acid (HCA), the active ingredient of Garcinia cambogia, exists in the rind or exocarp of Garcinia cambogia, accounting for 20-30% of the dry weight. HCA is a competitive inhibitor of adenosine triphosphate-citrate lyase (ATP citrate lyase), which catalyzes the extramitochondrial breakdown of citrate to oxalacetate and acetyl coenzyme A (Acetyl CoA), thereby limiting acetyl coenzyme A Availability of A, and therefore, HCA is able to inhibit the synthesis of body fat. In addition, increasing the amount of citric acid that is not converted to acetyl-CoA accelerates glycogen production from glucose.
3. Resistant dextrin is a water-soluble dietary fiber that inhibits the absorption of fat and sugar. In meat applications, resistant dextrin can be used as a partial fat substitute to reduce the presence of fat as much as possible without affecting the taste and flavor. In addition, resistant dextrin absorbs water and swells, making people feel full, and also helps to delay the recurrence of hunger, thereby reducing food intake.
