I am 5'11'' and a male of course. I was fat all my life. In all my little kid pictures I had fat and was chunky all over(stomach, thighs, butt) and will turn 25 in december. So I believe unless you have some medical condition you CAN lose practically all fat all week long if you do some cardio and most importantly weight lifting! Right now I have underlying muscle everywhere and have this small pouch of fat I can pinch all over that I need to get rid of. I did it through diet and exercise and slowly took off the weight averaging just over 2 pounds/week weight loss over 8 months. I don't have extra skin or stretch marks either. Definately you have to include all the elements and stick to them or you'll screw it up. I actually want to get definition and don't even know if its possible but currently I'm still losing weight each week by keeping the intensity up in exercising so I'll come to that road soon. But I think if you can lose the fat and build muscle once you get to a certain point the profile will show through. Its basically all about building muscle, burning fat/colories through cardio, and dieting which is lots of healthy foods, not starving and creating a calorie deficit for the day, resting, and consistency.
