Keto diet gaining attention for rapid weight loss and health improvement! Learn everything from principles to practice and precautions.
Ketogenic Diet extremely restricts carbohydrates and uses fat as primary energy source. Consume 5-10% carbs, 20-25% protein, 70-75% fat ratio. State of producing ketone bodies in liver when carbs lacking and using them for energy is called ketosis. Generally enter ketosis when consuming under 20-50g carbs per day.
① Rapid weight loss: Decreased insulin promotes fat burning, water excretion. ② Blood sugar stability: Helpful for diabetics. ③ Appetite suppression: High satiety from ketones and fat. ④ Increased energy: Stable energy supply. ⑤ Enhanced cognitive function: Brain utilizes ketones. ⑥ Cholesterol improvement: Increased HDL, decreased triglycerides. However, individual differences exist and long-term effects need more research.
Allowed foods: Fatty meat (pork belly, ribeye), fatty fish (salmon, mackerel), eggs, cheese, butter, coconut oil, olive oil, avocado, leafy vegetables (spinach, kale), nuts (almonds, walnuts). Restricted foods: Grains (rice, bread, noodles), fruits (banana, apple), root vegetables (potato, sweet potato), legumes, sugar, processed foods. Maintain under 20-50g carbs per day.

Most symptoms disappear within 1-2 weeks.
