Japanese and Korean Female Celebrities' Favorite Black Coffee Diet:
3 Time Slots to Quickly Burn Calories
24 July 2025
Black coffee, with its low calorie content and high caffeine properties, has become a secret weapon for weight loss among Japanese and Korean female celebrities. Unsweetened, milk-free black coffee (such as Americano or Long Black) contains only about 9 calories, yet it effectively boosts metabolism, suppresses appetite, and accelerates fat burning, making it a favorite among stars pursuing a slim figure. Many Japanese and Korean celebrities have openly shared their experiences of using black coffee to aid weight loss, with Japanese comedian Mariko successfully losing 49 kilograms in a year through the coffee diet method!
Below, we will introduce the scientific principles behind black coffee for weight loss and the three optimal time slots for drinking black coffee to help you burn calories quickly!
The Scientific Principles of Black Coffee for Weight Loss
The weight loss effects of black coffee primarily come from its core component—caffeine—and its low-calorie nature. Below are the key principles behind its weight loss benefits:
- Boosts Metabolism: Caffeine stimulates the central nervous system, increasing the basal metabolic rate (BMR), which helps the body burn more calories at rest. Studies show that caffeine can increase metabolic rate by 3-11%, with noticeable effects within 1-3 hours after consumption.
- Promotes Fat Burning: Caffeine stimulates lipolysis, breaking down stored fat into usable energy, particularly when consumed before exercise, enhancing fat-burning effects. Hot coffee, compared to iced coffee, better promotes blood circulation, further improving fat-burning efficiency.
- Suppresses Appetite: Caffeine can temporarily reduce hunger and curb the desire to eat, helping to control total calorie intake. This is particularly effective in preventing overeating.
- Reduces Water Retention: Black coffee has a mild diuretic effect, helping to eliminate excess water from the body, reducing bloating and creating a slimmer appearance.
Precautions: For weight loss, choose unsweetened, milk-free pure black coffee and avoid high-calorie coffee drinks (such as mochas or caramel macchiatos), as they may counteract the benefits. Excessive consumption can lead to side effects like palpitations or excessive stomach acid, so limit intake to 800-1000cc per day. Black coffee should not fully replace water intake (ensure daily water consumption of body weight x 35-40cc).
3 Optimal Time Slots for Drinking Black Coffee to Quickly Burn Calories
1. Morning on an Empty Stomach (7:00-9:00 AM):
Benefits: Drinking black coffee on an empty stomach in the morning can kickstart your metabolism, activating fat-burning mode for the day. Caffeine boosts the basal metabolic rate, helping the body burn calories faster while suppressing hunger before breakfast, reducing the tendency to overeat.
Recommendation: Drink a 200-250cc cup of hot black coffee paired with a high-fiber breakfast (such as oatmeal or fruit) to prolong satiety and promote gut motility. Avoid staying on an empty stomach for too long to prevent excessive stomach acid secretion.
2. One Hour Before Exercise (10:00 AM or 4:00-5:00 PM):
Benefits: Drinking black coffee one hour before exercise enhances fat breakdown, making it ideal for aerobic activities (such as running or yoga) or high-intensity interval training (HIIT). Caffeine boosts exercise performance, allowing you to burn more calories while reducing post-workout fatigue.
Recommendation: Drink 200-300cc of black coffee (without added sugar or milk) paired with a small healthy snack (such as a banana or nuts) to provide energy for exercise. Hot coffee is more effective as it promotes blood circulation, accelerating fat burning.
3. One Hour After Lunch (1:00-2:00 PM):
Benefits: Drinking black coffee one hour after lunch can reduce fat absorption, suppress appetite, and curb afternoon snack cravings. Caffeine continues to boost metabolism, helping to burn calories from lunch while reducing water retention for a slimmer appearance.
Recommendation: Drink 200-250cc of black coffee, paired with intermittent fasting or a low-calorie diet (such as a salad or lean meat) for enhanced effects. Avoid drinking in the evening to prevent sleep disruption.
