Health Guide: How Many Calories Should I Eat a Day?


Eating is a necessary and enjoyable part of life. Many people say food is love. However, the purpose of food is fuel for the body, and one of the most important chemicals that your body uses is a calorie. We will look further into calories and how many we need to function.

What Is a Calorie?

Calories are units of measurement that indicate how much energy a food provides for the body. The more calories you eat, the more energy your body will use up.


A calorie deficit is when you consume fewer calories than you burn, and a calorie surplus is when there are more calories consumed than burned.


To lose weight, eat fewer calories than your body burns while exercising so that you enter a calorie deficit. There are many ways to reduce the number of calories in your diet, such as eating less food or not eating foods with added sugar.

How Many Calories Should I Eat a Day?

Where Should I Get My Calories?

The number of calories you consume should consist primarily of complex carbohydrates, such as starchy vegetables and whole grains. You should also make a third of your diet protein-based foods like meat, fish, poultry, beans, and milk products.


There are healthy fats to include in your daily diets, such as olive oil and canola oil. You should also get a small amount of healthy unsaturated fats from foods like fish, olives, nuts, and avocados.


Lastly, you need to avoid trans fat from foods that have partially hydrogenated oils added to them. Like saturated fat, trans fat raises the level of cholesterol in your blood.


The American Heart Association (AHA) has recommendations on where to get your calories from. Healthy foods to eat every day include the following:


  • Vegetables and fruits high in potassium, such as bananas
  • Whole grains, like oatmeal
  • Starchy vegetables, including sweet potatoes
  • Fatty fish like salmon


Other healthy foods to consume daily include lean protein sources like beans and eggs, unsaturated fats from foods like nuts and avocados, and low-fat dairy products. It’s good to remember that there’s sufficient protein in ground beef portions — so you might want to go for that as well.


The best way to approach your calorie consumption is to aim for a balanced diet of protein, carbohydrates, and healthy fats with each meal.
