One of the problems with losing weight is that as you lose weight, your daily calorie requirement also goes down. It takes energy to maintain the excess fat on your body, so as you lose the fat, you also require less food.
So a diet that will cause you to lose weight slowly when you're 10kg overweight, might well just be at maintenance level after losing half that.
But I have also go back to eating occasional snacks, which I should cut out again.

Just to give some quantity. A ball park figure could be 30 cal/kg just to maintain the things as they are.
80 kg needs about 2400 cal. 70 kg only 2100. So a 10 kg difference corresponds to about 300 cal. Mid latitude temperatures. If he/she lives in Siberia in winter he/she might need more
if the weight is 80 to go down to 70, than a 2000 cal/day will build up a deficit of about 150 cal/day. equivalent to about 150 gr of fat. Obviously if there is enough exercise not to loose muscles but fat. This is the basic thermodynamics, than there are all the nice complications of real life.
2000 cal/day is not uncomfortable but requires discipline and some care. Like using scales. 1600 is quite nice yet. 1000 is bearable but dangerous, whichever way one looks at it.
