Why track your weight?
Day-to-day weight jumps around — water, salt, sleep and meals can swing it by 1–2 kg. What matters is the trend over weeks. Tracking regularly turns noise into a clear signal, keeps you honest, and shows whether your plan is actually working.
How to weigh yourself properly
- Same time every day — first thing in the morning, after the bathroom, before eating
- Same scale, same surface, minimal clothing
- Judge progress by the weekly average, never a single day

How fast should I be losing?
0.25–0.5 kg (0.5–1 lb) per week is the sustainable sweet spot for most people. Faster than 1 kg/week usually means losing muscle too. Pair this tracker with the calorie deficit planner.
My weight went up overnight — did I gain fat?
Almost certainly not. A real kilogram of fat needs ~7,700 excess calories. Overnight jumps are water and food weight — watch the weekly trend instead.
