I don't see why it isn't possible. If you are already fat somewhat, execising your muscles will burn that fat. All you need to eat to build more muscles is high protien. That will provide the building blocks for building new muscle cells (which are more dense and weigh more than fat cells). The existing fat you have in your body can be used as energy for those muscles to burn. In fact, the more muscle you have, the more fat your body burns. . .that's assuming you don't substitute by eating a lot of carbs. I see no reason why with a diet high in protien and low in fat and carbs, you cannot both loose fat and gain muscle at the same time.
The idea that the fat you burn will be used to synthesize new muscle is a good one, but unfortunately unless you are a complete beginner, have exceptional genetics, and/or are on drugs, doesn't work too well in practice.
brikis98 is right on in that you are better off focusing on 1 goal at a time.
I am not saying the fat you burn will be synthesized into new muscle. I am saying fat is excess energy. Muscle can only be built from protien (amino acids more specifically). There is no way to convert fat to protien. But fat can provide the energy your body needs to carry out exercise and do work leaving any protien you consume free to be used to synthesize new muscles.
Right, but the extent to which that happens is entirely determined by genetics. Instead of using fat for energy, your body may instead prefer to break down your muscles to reduce the amount of energy you require. This is why it is difficult to cut down to a very low bodyfat without losing any muscle, as I am currently finding out. Taking it slowly helps, but you can't beat your genetics.
I agree. Genetics play a big part. But for the typical person, the body will metabolize carbs first (because it's easiest to break down) for energy. Next it will turn to fat because a gram of fat contains a little more than 2x the energy that a gram of protien does. (1 gram fat = about 9 calories, whereas 1 gram protien = about 4 calories. And as we know, calories = energy). Finally, if nothing else is available, your body can burn protien for energy.
