📐 How fiber needs are calculated

Fiber intake is calculated based on calories and health goals. Here's the guideline:

Fiber recommendations:

General: 14g per 1,000 calories
Women: 21-25g per day
Men: 30-38g per day
  • Minimum = 14g per 1,000 calories
  • Optimal = 25-38g per day
  • Fiber = Essential for gut health, weight management, and blood sugar control
Example: 2,500 calories per day
Fiber Target = 2,500 × 14 / 1,000 = 35g per day
This meets the general recommendation for men (30-38g)

Key insight: Most people only get about 15g of fiber per day - half of what they need. Increase fiber gradually to avoid digestive discomfort.
