Portionsgrößenguide — Visuelle Handportionen

A serving size is a standardised amount of food used as a reference for nutritional information. It varies by food type and national dietary guidelines. Common references: 85g for protein sources like meat or fish, 80g cooked for grains like rice or pasta, and 150g for vegetables.

Hand portions are surprisingly accurate because hand size scales proportionally with body size and caloric needs. Research suggests hand portions typically land within 10–25% of weighed portions for most foods. They're ideal for restaurant meals, travel, or any situation where a scale isn't available.

A balanced meal typically includes 1 palm of protein, 1 cupped hand of carbohydrates, 1 thumb of fat, and at least 1 fist of vegetables. For weight loss, reduce carbs slightly; for muscle building, increase protein. Adjust based on your activity level and total daily needs.

Portion control helps manage calorie intake without strict calorie counting. People consistently underestimate portion sizes when eating freely — often by 20–40%. Using hand portions as visual anchors reduces this "calorie creep" and can create a modest deficit over time without feeling overly restrictive.
