That would be very hard to specifically answer for an individual as each person is just that, a unique case!
I will however let you know that each specifi type of fat distribution can usually be traced back to a particular hormonal imbalance.

In studies using testosterone injections, it was found that men lost belly fat even while sitting on the couch.

In my experience (and I have a lot) belly fat is usually a low testosterone problem.

There can be many problems that can cause this but to start, go and get a free (unbound) testosterone test from your doctor as well as an estrogen test.

Getting maximum uv sun exposure as well as red light therapy (whole health bed at planet fitness is infra-red light therapy) can help with this problem as well as morning sunrise greetings along with grounding.

Lowering your carbohydrate intake and replacing with fats (but not a super hig fat diet as it appears you may be in India or a part of south east Asia....moderate carb consumption is ok there as long as you are OUTSIDE in the sun with minimal clothing. Ie. Get out in your backyard and get your clothes off:)
