How much weight can I safely lose in a month?

Roughly 2–4 kg (4–8 lb) per month is a sustainable pace for most adults. More than that is usually water and muscle rather than fat.

Is losing 1 kg a week too fast?

For most people 1 kg (about 2 lb) per week is the upper end of healthy. If you're close to your goal weight, aim slower — around 0.25–0.5 kg per week.

Why am I losing weight faster in the first week?

Early loss is mostly water: cutting calories (especially carbs) drops stored glycogen, and every gram of glycogen holds water. Fat loss settles into a slower rhythm after one to two weeks.

What if I'm losing slower than 0.5 kg a week?

That's still progress. Slower loss preserves more muscle and is easier to maintain. Judge your trend over three weeks before changing anything.

What's a Healthy Rate of Weight Loss?

Guide · 3 min read

Lose it fast and you'll probably find it again. Lose it slowly and it tends to stay lost. Here's what a realistic, healthy pace actually looks like — and how to know if you're on it.

Quick answer: For most people, a healthy rate of weight loss is about 0.5–1 kg (1–2 lb) per week, or roughly 0.5–1% of your body weight. Faster loss is mostly water and muscle, and it's much harder to keep off.

The healthy range: 0.5–1 kg per week

Health authorities broadly agree: around 0.5–1 kg (1–2 lb) per week is the sustainable zone for most adults. If you carry more weight, the top of that range is realistic early on; closer to your goal, expect the low end or slower.

Why faster backfires

Crash deficits burn muscle along with fat, lowering the calories you burn at rest.
Very fast early loss is largely water, which returns as soon as you eat normally.
Aggressive restriction is hard to sustain — most people rebound past their starting weight.
Hunger hormones push back harder the faster you cut.

What it looks like on the scale

A 0.5 kg weekly loss is smaller than your normal daily fluctuation. On any given morning you may weigh more than yesterday while still losing perfectly on schedule — which is exactly why you should judge the weekly trend, not the daily number.

How to stay on pace

Weigh regularly, watch your weekly change, and compare it to your target rate. If the trend over two to three weeks is slower than planned, adjust; if it's much faster, eat a little more and protect your muscle.
