How to Stay Slim Like the Japanese

Maintaining a healthy weight without going hungry may seem like a challenge, but in Japan it’s part of everyday life. Despite consuming rice, noodles, and other carbohydrates virtually every day, the Japanese have one of the lowest rates of obesity in the world. What is its secret? The answer lies in their daily habits, in their conscious relationship with food, and in a culture that prioritizes quality over quantity.

Below, you’ll discover the key principles that explain how they manage to stay slim and healthy naturally, without extreme diets.

The Secret of Portion Control

One of the pillars of the Japanese diet is the habit of eating small portions, but varied. It’s not about avoiding foods, but eating moderate amounts of each.

Among the most common habits is hara hachi bu, a practice originating in Okinawa that means “eat until you are 80% full.” This allows you to enjoy meals without becoming heavy or excessive.

Bonus tip:
Try using smaller plates at home. This simple change can help you serve yourself less without realizing it, just like it does at the Japanese table.

Mindful eating and slow pace

In Japan, food is enjoyed without haste. Eating slowly allows:

• Better recognize satiety.
• Improve digestion.
• Reduce subsequent cravings.

Japanese culture teaches from childhood to savor every bite and to pay attention to the colors, smells, and textures of the dish. This creates a moment of calm around the meal and prevents automatic eating.

Bonus tip:
Avoid eating in front of screens. Spending a few minutes exclusively on your food will make you satiate yourself with less quantity.

The strength of traditional Japanese food

The Japanese diet is based on natural, simple, and unprocessed foods. Among the most common are:

• White rice as an energy base.
• Cooked and fermented vegetables (such as miso, daikon, pickled cucumber).
• Fatty fish, rich in omega-3.
• Light soups, such as miso.
• Fermented foods, which improve intestinal flora.

Although they eat carbohydrates, these are usually accompanied by foods rich in fiber and lean proteins, which keeps energy stable.

Bonus tip:
Include more fermented foods in your diet: plain yogurt, kefir, kimchi, or homemade pickles can improve digestion and help you feel lighter.

Green tea as a lifestyle

Green tea is a daily drink in Japan, consumed not only for its taste, but for its benefits:

• Slightly increases metabolism.
• Reduces inflammation.
• Offers antioxidants that improve cellular health.

Many Japanese people take it during and after meals, substituting sugary drinks.

Bonus tip:
If you’re having trouble giving up soda, start by replacing at least 1 glass a day with green tea. Do this gradually until it becomes a habit.

Healthy snacks and small portions

Unlike other countries, in Japan snacks are usually:

• fresh fruits,
• small portions of nuts,
• algae,
• low-sugar rice crackers,
• or mini portions of traditional sweets.

The key is not to eliminate snacks, but to choose more natural options and consume small portions.

Bonus tip:
Always have pre-prepared healthy snacks on hand. If you wait until you’re hungry to decide, you’ll usually opt for something ultra-processed.

Less sugar and fewer ultra-processed foods

Although there are delicious sweets in Japan, their consumption is moderate. Most of the day’s food is fresh and cooked at home. In addition, the portions of desserts are small, which allows you to enjoy without excesses.

Fast food is also avoided as a daily habit, reserving it for special occasions.

Bonus tip:
If you have a sweet tooth, reduce the amount of sugar in your recipes or choose smaller sizes. The key is in balance, not total restraint.

Daily habits that keep the Japanese population slim

In addition to food, daily activity is essential. Among the most common habits are:

• Walk several times of the day (to work, to the subway, to the supermarket).
• Use public transportation instead of the car.
• Maintain an active life within the home (tidying, cleaning, cooking).
• Include short stretches throughout the day.

All of this adds up to a stable caloric expenditure without the need for intense gym routines.

Bonus tip:
Try to walk at least 15–20 minutes a day, even if it’s divided into short breaks.
