Is it possible to put on a kilo overnight?

We’ve all been there. You’ve been keeping track of what you eat, sticking to your exercise plan and drinking your water, but you step on the scales one morning and discover that you’ve miraculously put on a kilo overnight...

It’s a disconcerting and discouraging experience which is a very common occurrence among many people trying to lose weight.


But is it actually possible to gain a kilo of fat in a single day? Looking at it from a scientific point of view, you need to consume about 3,500 calories more than you burn to gain 500g of fat. In other words, to gain one kilo in a day, you’d have to eat nearly 10,000 calories in just 24 hours. That is a load of calories!
