And something additional just for your reference.
3500 calories = 0.45 kg
And your resting metabolic rate for your height and weight of
173/53 = 1465
In short, you'd need 1465 calories a day to maintain your
weight.
So if you take in 1965 calories a day for a week, you might
actually gain .45kg in a week.
Remember this calculation excludes the amount of calories you're
burning a day, if you're running/basketball/soccer kinda thing,
adjust your diet plan accordingly.
