Starch and fat are considered major culprits for weight gain, but for modern diets, giving up starch and fat seems like an impossible task. In this context, pre-meal blocking is a recently emerging option. Consuming specialized blocking products or foods before meals can reduce the absorption of fat and starch, thereby achieving weight control or health management goals. NeoYouth introduces methods for blocking fat and starch absorption, and provides recommendations for pre-meal blocking.
The principle of blocking oil absorption
Blocking fat absorption primarily relies on specific components, such as chitosan or dietary fiber. These substances bind with fats, forming large molecules that are difficult for the intestines to absorb, thus preventing fats from entering the bloodstream. This not only effectively reduces calorie intake but also helps maintain healthy cholesterol levels.
Mechanisms that block starch absorption
Blocking starch absorption typically works by inhibiting the action of amylase, thereby reducing the breakdown of carbohydrates into absorbable sugars. This method helps control the rate of blood sugar rise and is suitable for individuals who need to manage their blood sugar levels. Common ingredients include white kidney bean extract, which effectively reduces the conversion of starch during digestion and lowers calorie absorption.
Recommended pre-meal absorption blocking
Here are four recommended foods or ingredients that can help block the absorption of fats or starches before meals:
- Mushrooms: The chitin in mushrooms, especially extracts from enoki mushrooms, has been shown to inhibit fat absorption, making it harder for fat to accumulate in the body and thus helping to reduce the formation of body fat. In addition, mushrooms are rich in dietary fiber, which not only provides a feeling of fullness, reducing food intake, but also promotes healthy gut function.
- Apples: The proanthocyanidins in apples can help enzymes in the intestines break down fat, thereby inhibiting lipid absorption; the polyphenols in apples also have the effect of inhibiting lipid absorption, which is beneficial for maintaining weight.
- Garcinia Cambogia Extract: Garcinia Cambogia contains hydroxycitric acid (HCA), which can inhibit fat production, suppress appetite and reduce weight. At the same time, it can inhibit the conversion of glucose into heat in the body and accelerate fat burning and metabolism in the body. It is a common ingredient in pre-meal fat blocking products on the market.
- White kidney bean extract: White kidney bean extract contains an inhibitor of α-amylase (which is also secreted by human saliva and pancreas) that can break down starch, effectively reducing the absorption of carbohydrates. It is suitable for lovers of high-starch foods and is a common ingredient in pre-meal starch-blocking products on the market.
Weight loss method that combines exercise and a healthy diet
Furthermore, weight loss isn't just about cutting out starches or exercising. Properly controlling starch intake, combined with appropriate exercise and a healthy diet, is key to achieving long-term, effective weight loss and making the journey easier and healthier. For example, a 10-minute light walk within 30 minutes after a meal can effectively control triglyceride levels in the blood, reducing fat accumulation. Combining a healthy diet with moderate exercise helps maintain consistent and effective weight loss.
Beauty Slimming helps you maintain a healthy body shape.
Meal blocking is an effective method for managing the absorption of fats and starches, suitable for those who want to control their weight or maintain health. Combined with a balanced diet, it can bring better health management results. However, the efficacy of meal blocking products on the market varies and may not be as effective as claimed. Relying solely on meal blocking may not actually achieve weight loss.
