In other words,what I wish to ask is will it take all the energy from the excess fat available till it is exhausted or will it take some from the excess fat and some from the muscle tissue ?

Hi Amit
I see that you have found some BMR calculators.
Fat is "energy-dense" - one gram of fat represents about 10 calories. Fat is used in preference to muscle protein so 700 calories of fat is about 70 grams.
I hope that you find a good dietitian. Although I am a doctor it is a PhD in biochemistry - I don't have medical qualifications but have taught medical and dietitian students the theory of metabolism. A dietitian will be able to offer your much more detailed advice than I can.
Good luck.
