⏳ A Complete Guide to Intermittent Fasting

Intermittent fasting (IF) regulates calorie intake while boosting metabolism by alternating between "eating windows" and "fasting windows," allowing you to easily lose fat and improve your health. Below, from a Hong Kong perspective, we break down five common methods, along with the scientific principles and practical tips to help you get started safely! 💪🌟

🌟 1. What is intermittent fasting?

Intermittent fasting means eating during a certain period of time and not consuming calories at all during the rest of the time (you can drink water or sugar-free drinks). The fasting time is used to induce the body to activate autophagy and fat burning mechanisms.

Scientific principles

• 12–16 hours after fasting, glycogen is depleted and the body turns to breaking down fat to produce energy, accelerating fat loss.

• The autophagy mechanism improves cell repair efficiency, fights aging and inflammation, and helps improve insulin sensitivity.

🔍 2. Comparison of the five most popular fasting methods

The editor recommends: Beginners should start with the 16/8 method, and then gradually extend the fasting time or try the 5:2 method after getting used to it.

🥗 3. How to eat during fasting?

• During the eating window, choose foods with high nutrient density:
  – High protein: fish, chicken breast, egg whites, to maintain muscle mass – High fiber: green vegetables, beans, brown rice, to prolong satiety – Healthy fats: avocado, olive oil, nuts, to stabilize blood sugar

• Avoid added sugars and refined starches: desserts, soda, white bread, to reduce insulin fluctuations

• Spread out your meals: 2–3 meals is ideal, with healthy snacks for each meal

🏃 4. Combine with exercise for faster results

• Aerobic + Strength : Arrange weight training and aerobic exercise during the eating window to build muscle and burn fat at the same time

• Fasting exercise : Do low-intensity aerobic exercise (such as brisk walking, stretching) in the morning before breaking the fast to enhance fat mobilization

• Post-workout replenishment : After exercise, supplement protein and carbohydrates within the eating window to help muscle repair

📅 5. Practice tips and precautions

• Hydration : Drink plenty of water, unsweetened coffee or tea during fasting to prevent thirst and hunger

• Gradual progress : For the first attempt, you can start with 12/12, gradually increase to 16/8, and then challenge longer fasting

• Avoid overeating : Don’t overeat during the eating window, savor every bite of food

• Monitor your body's reactions : If you feel dizzy, palpitations, or fatigue, shorten your fasting time or stop eating immediately.

• Special groups need to be cautious : pregnant women, diabetics, children, and heavy athletes need to consult a doctor
