Your stomach doesn't burn fat. Your body does.
If you mean when does your body burn fat, it's simple. When there is cortisol in your system from a stressful workout and your muscle mass is being used and maintained, you will burn fat. If cortisol is released but your muscles aren't being used much as in steady state cardio, muscle will be burned.
Focus on short, intense workouts and use your muscles rather than steady, boring cardio. This will make you fat and weak.
When building muscle, you are just making the muscle fibers stronger and bigger, they arnt multiplying. The amount of muscle mass you have does not matter how difficult it is to burn fat. Fat is fat. Muscle is muscle. The more fat you have, the longer it will take to burn that off. Another thing, fat is generally burned off all around the body, not just in a concentrated area such as the stomach. If you are trying to burn off stomach fat, intense running will work better than doing situps. And if you are trying to get your abs stronger/harder, do situps using a weight to decroease the amount of time it will take
No, but you can have a layer of stomach fat on top of muscle. If so, that will hide the muscle and not look good.
when you burn off fat you will always burn of muscle too, but if you diet and exercise correctly you muscle burn off will be minimal. The fat burning supplements don't actually burn off fat, they just increase you metabolism
Technically, yes. You will burn the fat that is marbled into the muscle that provides energy for the muscle to burn. But the fat that we can see, subcutaneous fat, will not be affected.
No, infact running with an empty stomach will have an adverse affect on the fat you can burn. Without food in your stomach for energy you will not be able to run very far, and therefor will not be able to burn much fat.
Workout just like you normallw would! Muscle will burn fat.
Studies have shown that localized exercise does not burn fat in those areas. Sit-ups will not burn stomach fat and face-crunches will not burn face fat. These exercises only tone and build muscle. To lose fat you need to burn more calories than you consume by doing cardiovascular exercise.
Of course build more muscle , because when you have more muscle in the body , help burn about 50% more body fat , that you are burn. :-) .
yes
no yes
Exercise and diet combined is the best way to lose stomach fat. Eating a well-balanced diet and increasing the number of calories you burn, combined with muscle toning exercises is the best option.
In order to get a flat stomach, the most important factor is reduce the amount of sugary and fatty foods you consume. Then you need to be able to burn fat through aerobics. You cannot expect to see a flatter stomach by only to abs workout, those will only build muscle, not burn the fat you want to get rid of.
