I am 30 years old female, 5'2 and my weight is 165. i exercise: jogging/walking - at least 5 miles 3-5 days a week, plus i do cardio. i cant loose wgt?

There can be many : reasons that could include not the amount of exercise but the degree of intensity and whether any strength training is involved. You need to do interval training with varied intensity as well as look as to your food intake as ultimately the type of food and calories play a role. If still not losing weight, then see your doctor for evaluation for such issues like thyroid problem .

U can do it: Your body burns calories with exercise and its internal activity such as beating heart breathing etc. Weight change is simply calories in and calories out. 3500 cal is one pound of fat. If you are up you will gain and id down you will lose a pound. 500 cal daily is a pound a week. You should look to what you are eating and drinking. wine pop snacks seconds. eating while doing other things.
