Did a body fat test recently and here's the result...

Age: 31
Height: 177.2 cm (I always thought i was 1.78cm)
Weight: 63.3 kg
BMI: 20.2
BMR: 6351 kJ
1518 kcal
Impedance: 518
Fat%: 17.0%
Fat Mass 10.8 kg
FFM: 52.5 kg
TBW: 38.4 kg

Desirable Range
Fat%: 17 - 23%
Fat Mass 10.8 - 15.7 kg

Target BF% is : 20%
Predicted weight : 65.7 kg
Predicted fat mass : 13.2 kg
Fat to gain : 2.4 kg

Which means I'm suppose to gain at least 2.4kg of fats?
I still got fats which I hope to lose so that my lower abs can be more defined...
