Did you know that 1 kilogram of weight equals 7500 calories? So, if you want to lose 5 kilograms, you would need to "save" 37,500 calories while never exceeding the allowed daily amount. Put another way: if you ate 500 fewer calories every day than what's optimal, you would lose 5 kilograms in 75 days.

But that’s nearly impossible!

And not because eating 500 fewer calories each day isn’t doable, but because no one has the willpower to stick to it for that long.

That's why it’s always good to know shortcuts for losing accumulated fat or calories more quickly.

How can you lose calories quickly?

Did you know that one hour of intense boxing (even hitting a punching bag) burns 800 calories? That's why boxing is one of the most effective physical activities.

One hour of squash requires 750 calories. Housework will "cost" you a good 100 calories. Rowing burns 720 calories, while rowing in the gym burns 440 calories.

For one hour of moderate-paced outdoor running, you need 700 calories per hour, and for one hour of cycling, you need 600 calories. If you use a stationary bike, you’ll burn "only" 540 calories.

An hour of playing soccer will save you 600 calories, basketball 475 calories, and tennis 470 calories. If you do all of this in a gym, you will burn about 20 percent less.

From all this, we can conclude that boxing is the best weight-loss sport, but there is one activity that burns even more calories. If you are in the water and swim leisurely, you will burn 480 calories per hour. But if you swim intensively and with all your strength for at least half an hour, you will burn 820 calories.

Therefore, let this simple calculation prevail. If you are at the sea and go into the water three times a day for 20 minutes, and each time you swim intensely for 10 minutes, then by actively spending your holiday, you can lose the intended 5 kilograms in 14 days.

So make good use of your vacation.
