低醣飲食就是透過採取低碳水化合物飲食法，讓肝臟產生酮作為消耗的能源。低醣飲食又有各種名稱 - 例如生酮飲食、低碳水化合物飲食、低碳水化合物高脂肪(LCHF)等。
低醣飲食其中一個特點是你攝取的碳水化合物(例如含糖食物、米飯、麵食和麵包等)含量相當低。相反，你偏好其他的食物，這些食物蘊含蛋白質、天然脂肪，也包括各類蔬菜。
研究表明，低碳水化合物飲食會令到體重減輕，其他健康指標也能得以改善。
目前越來越多研究顯示，我們無需再過分擔心從飲食中攝取天然脂肪會造成不良後果，以往那些教科書中提到的食物金字塔建議也應該作出適當更改。低碳水化合物飲食是透過減少攝入糖和澱粉為目的。你可以進食其他美味的食物，直到飽暖，仍然能達到減肥的目的。
低醣飲食的原理
當你避免過量進食糖和澱粉類食物，你的血糖水平便會趨於穩定，胰島素水平也會慢慢下降。這會增加體內脂肪燃燒，使你得到飽腹感覺，減少食物攝入量，並導致體重減輕。
研究證明，低碳水化合物飲食具有輕鬆地減肥和控制血糖等優點。
基本飲食方式
多選擇食：肉類、魚類、蛋類和生長於地面的蔬菜和天然脂肪(例如牛油)。
避免進食：糖和澱粉類食物(如麵包、意大利粉、米飯、豆類和薯仔等)。
簡單地講，低醣飲食就是：選擇正確的食物，當你餓的時候就進食，直至飽暖。
Keto diet is one of the trending topics right now. Let's learn more about it.
A keto diet is well known for being a low carb diet, where the body produces ketones in the liver to be used as energy. It’s referred to as many different names – ketogenic diet, low carb diet, low carb high fat (LCHF), etc.
A keto diet is low in carbohydrates, like sugary foods, pasta and bread. Instead, you eat real foods including protein, natural fats and vegetables.
Studies show that low-carb diets result in weight loss and improved health markers.
Studies now show that there’s no reason to fear natural fats. On a low-carb diet, you instead minimize your intake of sugar and starches. You can eat other delicious foods until you are satisfied – and still lose weight.
How does it work?
When you avoid sugar and starches, your blood sugar stabilizes and the levels of the fat-storing hormone insulin drop. This increases fat burning and makes you feel more satiated, reducing food intake and causing weight loss.
Studies prove that a low-carb diet makes it easier both to lose weight and to control your blood sugar, among other benefits.
The basics
Eat: Meat, fish, eggs, vegetables growing above ground and natural fats (like butter).
Avoid: Sugar and starchy foods (like bread, pasta, rice, beans and potatoes).
Eat when you’re hungry, until you’re satisfied. It’s that simple.
