Many active people (women included) eat 3000+ calories a day and stay plenty lean.

The recommended daily calorie intake is 2000 for women and 2500 for men.

The recommended daily calorie intake for weight loss is 1500 for women and 2000 for men.

A 5-year-old needs about 1400 calories or more every day.

The minimum daily calorie intake for a long-term diet without medical supervision is 1200 for women and 1800 for men. Eating less than that eventually leads to starvation mode (a real–yes, real–state of biological stress characterized by decreased metabolism, increased cortisol production, and heart, brain, organ, bone, and muscle damage).

A 2-year-old needs about 1000 calories or more every day.

Most people can’t even imagine eating 1000 calories in a day. You’ll get 1,357 Google results if you search for the exact phrase “1000 calories is way too low” or “1000 calories is way too little”…but you’ll get even more results if you Google the same phrases for 1200 calories, because few people consider dipping below 1200.

A 3-digit daily calorie intake puts you at high risk for binge-eating, slowed metabolism, bone and muscle loss, nutritional deficiencies, gastrointestinal issues, infertility, hair loss, mood swings, and depression. Oh–and sudden death.

900 calories is less than what a completely sedentary, 5'0", 80 lb, 70-year-old woman burns daily (keeping in mind that your metabolism slows with age).

A very low calorie diet, also known as a starvation diet, is 800 calories a day or less. It is prescribed by doctors to obesity patients who need to lose weight quickly, is specially formulated to be nutritionally complete, and is monitored by medical professionals to prevent sudden cardiac arrest and death. It is considered an extreme diet.

600 calories a day or less is literal starvation.

500 calories is less than the daily calorie needs of the average 1-month-old.

400 calories is less than the daily calorie needs of the average newborn.

300 calories is less than what the adult brain alone burns every day.
