Calorie banking explained
What calorie banking is, how to use it well and where the limits are.
Guide
Clear, honest and sourced: everything about counting calories by the week.

In short
The Weekfuel guide covers everything you need to lose weight with a weekly mindset: how to calculate a weekly calorie budget and your weekly deficit, how to eat more on weekends without derailing your goal, and how much protein and how many steps per week make sense. Every article starts with a short answer and lists its sources.
Our articles follow one simple idea: no single day decides your progress. What counts is the total over weeks. That's why we always run the numbers for seven days and show how a big Saturday balances out with calmer weekdays. Figures come from peer-reviewed studies, EFSA and the WHO, and we're upfront about where research has limits.
