The Science

Why daily weight is misleading

Your body weight fluctuates by 1-3 kg daily due to water retention, food in your digestive system, and hormonal changes. This makes it nearly impossible to see real progress day-to-day.

Our Exponentially Weighted Moving Average (EWMA) algorithm, based on The Hacker's Diet methodology, smooths out these fluctuations to reveal your true weight trend.

The result? Less frustration, more clarity, and a true picture of whether your diet is actually working.

Pro tip: The trend line takes about 10 days to fully adapt to your true weight. Stick with it for the most accurate results!

Health-Aware

Know if you're on the right track

Not all weight loss is healthy. Losing too fast can lead to muscle loss, nutritional deficiencies, and rebound weight gain.

Weight Control automatically categorizes your progress based on evidence-based guidelines. You'll always know if your current rate is sustainable and healthy.

When you hit a plateau (and you will—it's completely normal!), we provide actionable tips to help you break through without extreme measures.

The sweet spot: Research shows that losing 0.5-1.0 kg per week maximizes fat loss while preserving muscle mass. Our coaching helps you stay in this range.
