The efficacy and function of grapefruit for weight loss

Yuzu is helpful for weight loss, and its effects and functions mainly include promoting digestion, increasing satiety, regulating blood lipids, supplementing vitamins, and improving metabolism. Pomelo is low in calories and rich in dietary fiber and vitamin C, making it suitable as an auxiliary food during weight loss.

1. Promoting digestion

Pomelo is rich in dietary fiber and pectin, which can stimulate gastrointestinal peristalsis, help food pass through the digestive tract quickly, and reduce fat absorption. Dietary fiber can also adsorb oils and waste in the intestines, promote bowel movements, and alleviate constipation problems. People with weak gastrointestinal function need to control their food intake to avoid causing diarrhea.

2. Increase satiety

Pomelo has a high water content and low calories, which can occupy stomach space after consumption, delay gastric emptying time, and reduce the intake of other high calorie foods. Eating grapefruit in moderation before meals can help control appetite and avoid overeating. However, it should be noted not to rely solely on grapefruit as a meal replacement to avoid nutritional imbalance.

3. Regulating Blood Lipids

The active ingredients such as naringin in grapefruit can inhibit cholesterol synthase activity, reduce low-density lipoprotein cholesterol levels, and increase the proportion of high-density lipoprotein cholesterol. Long term moderate consumption can help improve blood lipid abnormalities and reduce visceral fat accumulation. Hyperlipidemic patients can include it in their daily diet, but it needs to be accompanied by medication treatment.

4. Supplementing vitamins

Pomelo is rich in vitamin C and B vitamins, which can promote the activity of fat metabolism enzymes and accelerate the process of fat breakdown. Vitamin C also has antioxidant properties and can reduce free radicals produced during weight loss due to accelerated metabolism. Eating 200 grams of grapefruit per day can meet over 80% of an adult's daily vitamin C requirement.

5. Improving Metabolism

Citric acid and minerals in grapefruit can participate in the tricarboxylic acid cycle, increase basal metabolic rate, and promote energy consumption. Its unique aromatic hydrocarbons can also stimulate the activity of brown adipose tissue and increase calorie expenditure. But people with metabolic abnormalities need to combine exercise to effectively exert this effect, and relying solely on grapefruit has limited effectiveness.

During weight loss, it is recommended to consume 200-300 grams of grapefruit per day, which can be divided into two portions between meals. Avoid consuming large amounts on an empty stomach to prevent irritation of the gastric mucosa. For those with gastrointestinal sensitivity, peel the skin and consume the fruit pulp. It is necessary to have a balanced diet and regular exercise, and not rely solely on grapefruit for weight loss. People taking antihypertensive or statin drugs should consult a doctor, as grapefruit may affect drug metabolism.
