How Much Weight to Lose Per Week?

The short answer: 0.5 to 1% of your body weight per week. The long answer explains why most people get this exact part wrong – and why "faster" almost always turns into "slower" in the end.

Everyone wants to be leaner by yesterday. Fair enough. But your body doesn't think in calendar weeks – it thinks in survival. Cut energy too hard and it switches to economy mode: less warmth, less urge to move, more hunger. That's why the question of pace isn't really about patience. It's about strategy.

The healthy range, in numbers

The rule of thumb is a weekly loss of 0.5 to 1% of your body weight. Run it against your own number:

• 60 kg → roughly 300 to 600 g per week
• 80 kg → roughly 400 to 800 g per week
• 100 kg → roughly 500 g to 1 kg per week

The more you weigh, the more you can lose at first – even in absolute kilos. The closer you get to your goal weight, the slower it goes, and the more it matters to sit at the lower end of the range. The last few kilos aren't stubborn, they're just honest: your body has less left to give now.

Why faster is rarely better

Crash diets show big numbers early. The catch: a good chunk of that is water and muscle, not fat. And muscle is exactly what you want to keep – it shapes your body and keeps your energy burn up. Lose it and your baseline burn drops, so the moment you eat normally again the weight comes back. Often more than you lost. That's the infamous yo-yo, and it's not weak willpower, it's biology.

Losing weight isn't a sprint you win. It's a pace you hold.

Then there's the mental side. A harsh deficit leaves you hungry, irritable and tired. You sleep worse, train with less drive, and at some point the whole thing tips over. A moderate pace feels almost unremarkable – and that's the point. What doesn't feel like punishment is what you keep doing.

How to protect your pace

Three things keep you in the healthy zone:

• Protein high. Around 1.6 to 2 g per kilo of body weight protects muscle and keeps you full.
• Train strength. Two or three sessions a week give your body a reason to hold onto muscle.
• Don't trade away sleep. Too little sleep raises hunger and undercuts fat loss.

What the scale won't tell you

Weigh yourself once a week at most, in the morning, under the same conditions – or average a few days. Your weight swings a kilo or more day to day, just from water, salt and digestion. A single number says almost nothing. Only the line over four weeks shows the truth. And sometimes the scale stalls while your waist still shrinks – so pull out the tape measure or an honest photo too.

Bottom line: don't set a date, set a pace. Lose half to one percent a week and you'll be surprisingly far along in six months – and you'll keep it. Try to do it all in four weeks and you'll celebrate briefly and regret it for a long time.
