How Many Calories Should I Eat a Day?

How to lose weight is a question that we all want the answer to. We know that our body needs energy in the form of calories to function properly. We are also told that we need to burn calories in order to lose weight.

In order to know the answer to “How many calories should I eat a day to lose weight?” the first step is to find out how many calories you should eat a day to maintain your weight. This amount depends on your gender, your age, and also the level of physical activity you get in a regular day; i.e. how active you are. If you eat more calories than you expend, you will gain weight. If you eat less calories than you expend you will lose weight. If you consume calories approximately equal to what you expend, then your weight will be maintained. Simple so far? Good, then let’s get into the specifics. . .

How many calories should I eat a day? This of course depends on what you are trying to achieve. On the table below you will find the estimated or approximate amounts of calories needed to maintain weight, or to maintain a calorie balance (meaning that the person neither gains nor loses weight). Once you know the calories to maintain weight, you will be better able to design an eating routine around that figure. The table below covers men and women separately, and also breaks down the estimated calories needed based on lifestyle; sedentary, moderately active, and active.

You will find that the less processed foods will contain fewer calories on average than the more highly processed and refined foods.

Also using fat-free or low-fat milk and trimming fat from meat will cut out a lot of unnecessary calories. Some oils that are known to be high in monounsaturated fatty acids are canola, olive, and safflower oils. Some oils that contain high amounts of polyunsaturated fatty acids are soybean, corn, and cottonseed oils.
