3kg a week is dangerous!!! you know of course after the diet you gonna be picking it up double?
I say its a lifestyle and if you don't eat properly its just going to jump back... and you are also gonna have fat rolls because you are losing so much weight in such a fast period...
Been on about 800 calories a day for 6 weeks and lost about 2kg a week..but I want to lose faster..
...what is the minimum calories per day intake to achieve that?
No for pete sakes. It does not require a lot of dedication. It's just stupid to try and lose weight in a week. There are no quick fixes to losing weight and i cannot believe there are people on here who give out such stupid advice.
*gives up*
It's also not healthy to do that dablakmark8. Google has a wealth of information on quick diets to drop weight over a couple of days. Doesn't mean it's medically advised to do this. You will put strain on your organs/body by pretty much starving yourself. Secondly, you are more inclined to put on weight after losing it as you can only hold out so long and your body stores whatever you put in your mouth as fat because it's not sure when it's going to get fed again.
The correct way to lose weight believe it or not is to eat more regularly and eat smaller portions of healthy foods. This speeds up your metabolism and aids your body in burning fat faster. Also, you have to include exercise into any healthy diet as eating celery sticks and not exercising is not going to get you anywhere.

Trying to lose 3kg per week, is not realistic; rather try for 500g!
