most helpful answer you body needs about 15 calories per pound of ideal body weight (i do not know what you currently weigh). if you eat less and burn more you will lose weight. in a chronic situation where you are losing weight your body will attempt to lower your metabolic rate to compensate for this slowing down you weight loss. in addition to calories you body needs a balance of protein (more for men; less for women) fat and carbohydrates to achieve optimum health. i don't know your sex or what your goals are but it may be best to seek the counseling of a good nutritionist.
is it possible to have too few calories in a day? . the webmd food and fitness planner suggests that for my current weight and my weight loss target i should be consuming 1880 calories per day and burning 250 leaving a total of 1630. many days i consume less than 1880 and burn lots more than 250. is this bad for me as my body isn't getting the difference of 1630 calories at the end of each day? . for example today i consumed only 1190 and burnt 608 leaving my body short of 1048 based on the chart.
