Japanese Diet Explained: Strict 2-Week Plan with Big Risks

Lose 7 kg in 13 Days? The Truth About the Japanese Diet

Each summer, the familiar yearning to “fit into that dress” resurfaces—and with it, the talk of fast-track slimming diets. Once again in the spotlight is the “Japanese diet,” which claims up to 8 kg of weight loss in just 13 days. It sounds like a dream—but is it realistic or safe?

What is the 'Japanese Diet'?

Despite its name, this regimen bears little resemblance to traditional Japanese cuisine—no rice, miso soup, or sushi. Rather, it's a strict protein-vegetable detox with ultra-low calories (approximately 800–1,000 kcal/day), and total bans on:

  • Salt
  • Sugar
  • Bread
  • Alcohol

Sample Daily Menu

With no snacks or desserts—and not even porridge—here’s an example of the almost Spartan daily plan:

  • Day 1: black coffee (no sugar), boiled egg, stewed cabbage, fish
  • Day 2: coffee, carrot, beef, apple
  • Day 3: coffee, toast, cucumber, eggs, tomato

Why People Try It

  • Rapid weight reduction: up to 5–8 kg in two weeks
  • A hard reset on overeating habits
  • No need to log calories or plan complex meals

Popular in spring/summer for quick “beach body” results

Hidden Pitfalls

  • Extremely low calories lead to dizziness, weakness, irritability
  • Unbalanced nutrition: too little healthy fat, fiber, calcium
  • Metabolism may slow down, with weight quickly returning
  • Contraindicated for gastritis, diabetes, kidney, or heart conditions
“This is not a lifestyle, but a short, tough sprint—and not everyone finishes this marathon,”

warn nutritionists.

Who the Diet Is For

Only healthy individuals with strong willpower should consider this — and only for a short period, after consulting a medical professional. This is not a long-term health plan, but an emergency tool to shed weight fast.

The Japanese diet isn’t about taste or enjoyment—it’s pure control and results, requiring discipline and a clear understanding of its transient benefits and serious health risks.
