The average American diet has changed over the years, with the average American consuming 2,481 calories a day in 2010, about 23% more than in 1970. This is more than most adults need to maintain their weight, according to the Mayo Clinic’s calorie calculator. The average daily calorie intake varies depending on factors such as age, gender, and activity level. For example, a 40-year-old man of average height and weight who is moderately active needs 2,400 calories, while a woman with similar characteristics needs 1,850 calories. Eating too few calories can lead to health issues, with diets of less than 1,000 calories per day associated with nutrient deficiencies and an increased risk of eating disorders. On the other hand, consuming too many calories can also have negative health consequences, with only 9.1% of people reporting consuming 3,001 calories or more per day, which is generally more than the body requires unless there are specific circumstances such as athletic training, pregnancy, or medical advice.

What You'll Learn
The average American consumes 2,481 calories a day
Nearly half of these calories come from just two food groups: flours and grains (581 calories, or 23.4%) and fats and oils (575, or 23.2%). This is up from a combined 37.3% in 1970. Meats, dairy and sweeteners provide smaller shares of our daily caloric intake than they did four decades ago; then again, so do fruits and vegetables (7.9% in 2010 versus 9.2% in 1970).
While the average number of calories consumed by Americans is 2,481, a survey found that 36.4% of respondents thought they ate between 1,001 and 2,000 calories per day, which is slightly below average but is acceptable for most bodies to thrive on (especially if you’re trying to lose weight). Only 9.1% believed they ate 3,001 calories or more on an average day, which is generally more than a body needs (unless you’re an athlete, trying to bulk up, pregnant, or have discussed your diet with a doctor or nutritionist).
It's important to note that eating too little can also be harmful. Consistently eating 1,000 calories or less a day may be a red flag for an eating disorder.

36.4% of Americans eat between 1,001 and 2,000 calories a day
The average American diet has changed over the years, with people consuming more calories than they used to. In 2010, the average American consumed 2,481 calories a day, which is about 23% more than in 1970. This is more than most adults need to maintain their weight. For example, a 40-year-old man of average height and weight who is moderately active needs 2,400 calories, while a 40-year-old woman with corresponding characteristics needs 1,850 calories.
However, a survey found that only 9.1% of respondents believed they ate 3,001 calories or more on an average day. Meanwhile, 36.4% of respondents thought they ate between 1,001 and 2,000 calories per day, which is slightly below average but acceptable for most bodies to thrive on, especially if one is trying to lose weight. Eating less than 1,000 calories a day can lead to nutrient deficiencies and is a concern for eating disorders.
The sources of calories in the American diet have also changed over time. In 2010, nearly half of the calories consumed came from just two food groups: flours and grains (581 calories, or 23.4%) and fats and oils (575, or 23.2%). This is an increase from 37.3% in 1970. At the same time, the share of calories from meat, poultry, and fish has stayed the same at 17% of total calories between 2000 and 2010. However, within this category, there has been a shift from red meat to poultry and fish.
While the average American diet may provide enough calories for weight maintenance, it is important to note that the quality and sources of these calories matter for overall health and well-being. A balanced diet that includes a variety of food groups is essential for meeting nutritional needs and maintaining a healthy weight.

The average American diet is high in calories, with the average American consuming 2,481 calories a day in 2010, about 23% more than in 1970. This is more than most adults need to maintain their current weight. For example, a 40-year-old man of average height and weight who is moderately active needs 2,400 calories, while a 40-year-old woman with corresponding characteristics needs 1,850 calories.
However, there is a wide range in the number of calories Americans believe they consume. While 36.4% of people think they eat between 1,001 and 2,000 calories per day, 9.1% believe they eat 3,001 calories or more on an average day.

Eating too many calories can lead to weight gain and health problems.
There is also a small percentage of people who eat very few calories. 6% of people believed they consumed less than 500 calories on an average day, which is not enough to sustain brain function and can lead to serious malnourishment. Diets of less than 1,000 calories a day are associated with significant nutrient deficiencies and can be a red flag for an eating disorder.
