Insanity: Hard time losing this belly fat!

Hi to whomsoever listening!!

I'm a 30 yr old male from India, into the 4th week of Insanity.

I can marginally see the difference in my body as my arms and chest are slowly showing shape. By shape I don't mean ripped. I have lost fat around my face, neck and I look slimmed down. And my thin arms make me look skinny.

But my belly fat is still visibly there. Is it too soon to hope for flat abs? How long does it take to lose it? I've noticed that my belly keeps changing shape. Somedays I feel its gone down somedays its still big.

My daily calorie intake is under 2000 cals. I may not be following the Insanity nutrition plan to the T. But I have been regular with my workouts yet.

Also the fact that I am a mild hemophilia patient, I may not be pushing hard or 'digging deeper'. But that doesn't mean my body is not sore after a morning's workout.

Please advice if I am doing something wrong.

Thanks.
