HUMAN NUTRITION

Detailed explanation-1: -40 calories per serving is considered low; 100 calories per serving is considered moderate; and 400 calories or more per serving is considered high.

Detailed explanation-2: -400 calories is about one fifth of what you should be eating and eating that little will damage your health in the long run. It is not too much, it is far to little. Talk to someone, get support and please begin eating at least 2000 calories a day. Do not restrict your food.

Detailed explanation-3: -Eating only 400 calories per day would be considered an extremely low-calorie diet and could have serious consequences for your health. At such a low calorie intake, your body would not be getting enough nutrients to function properly. You would likely feel fatigued, weak, and experience difficulty concentrating.

Detailed explanation-4: -For weight maintenance, the Dietary Guidelines for Americans 2020–2025 suggest a range of 1, 600–2, 400 calories for women and 2, 200–3, 000 for men-so you could consider anything below these numbers a low-calorie diet.
