Formula
fibre g = daily kcal × 14 g per 1000 kcal= 30.8
Note
Simplified nutrition model using standard reference constants (protein and carbohydrate 4 kcal/g, fat 9 kcal/g, alcohol 7 kcal/g, 1 kg of body fat about 7700 kcal, salt to sodium factor 0.393). Real energy needs and body composition changes vary between individuals. This is not medical, dietetic or nutritional advice; consult a qualified health professional before changing your diet.

How is a daily fibre target derived from calorie intake?+
The calculator typically applies a standard guideline of about 14 grams of fibre per 1,000 calories consumed, which is the basis several national dietary guidelines use to scale fibre recommendations to individual calorie needs rather than giving one fixed number for everyone.
Why is fibre recommended relative to calories rather than as a flat number?+
People with higher calorie needs generally eat more total food volume and can reasonably be expected to consume more fibre-containing foods, so scaling the target to calorie intake keeps the recommendation proportional to what's realistically achievable through a normal diet at that intake level.
What's the difference between soluble and insoluble fibre for this target?+
This calculator gives a total fibre gram target without splitting by type, but both matter: soluble fibre (in oats, beans, and fruit) helps manage cholesterol and blood sugar, while insoluble fibre (in whole grains and vegetable skins) supports digestive regularity — a varied diet naturally covers both.
Why do most people fall short of their calculated fibre target?+
Diets low in whole grains, legumes, fruits, and vegetables and high in refined and processed foods are the primary reason average fibre intake in many countries falls well below recommended levels, often by close to half, regardless of total calorie intake.
Should I increase fibre intake quickly to hit the target?+
No, sudden large increases in fibre intake commonly cause bloating, gas, and digestive discomfort — it's generally recommended to raise fibre gradually over several weeks while also increasing water intake, rather than jumping straight to the calculated target.
