The number of calories necessary to maintain a weight of 170 pounds is based on your gender, activity level and individual metabolic rate. Eat as healthfully as possible to be sure you get the nutrients you need while staying within your ideal caloric range.
Males and Females
Males require more calories to maintain their weight than females. A 170-pound male should consume between 2,210 and 2,550 calories daily for weight maintenance, while a female of the same weight should consume between 1,700 and 2,040 calories, according to the University of Maryland Medical Center website. Because 1 pound is equivalent to 3,500 calories, eating 500 calories a day more than you normally eat and burn can result in a gain of 1 pound a week, while eating 500 less calories each day can result in a loss of 1 pound per week.
The more active you are, the more calories you need to consume daily to maintain your weight. If you are moderately active, aim toward the higher end of the recommended range, while if you are fairly sedentary, set your goal at the lower end of the range.
Whether you are at a healthy weight or overweight, make small changes to your diet to incorporate more healthy foods and fewer junk foods into your diet. Focus on fresh, whole foods such as fruits and vegetables, whole grains, low-fat dairy products and lean protein sources.
