How much weight should I loose per week?

"How much weight should I loose per week?" -this is one of the most freqent questions that people ask me.
Let me explain: It should be 0.5kg of fat per week. This equates to a calorie deficyt of about 3500kcal per week, or 500 kcal per day. This is not enough to invoke any major starvation response. Is it possible to loose weight much more quickly? Yes, but - it will be mostly water and you will gain it back fast (yo-yo effect) and your metabolism will slow down.
