Calorie balancing. Eat less, drink more. Of course you might end up killing yourself with that approach, so I recommend cutting back on the drinking instead.
Approximate calorie numbers:
3 cans of pilsner beer (~460 kcal total, around a quarter to a fifth of the daily maintenance calories for someone of your weight, depending on activity level) = 5 vodka shots = 4 gin or whiskey shots = 80 g of chocolate = 300 g of chicken breast = 260 g of veal = 6 eggs = 170 g of white bread = 22 tomatoes = 4 large bananas.
