Eating only an apple and a boiled egg for breakfast consumes too little calories, about 200 calories, which is easy to lead to hypoglycemia, which is not good for your health for a long time.

Can be eaten with steamed bread, bread, noodles and other staple foods, and the total calorie intake should be kept at 30% of the human metabolism at most.

Generally, the calories required for human metabolism are about 1800 calories for men and 1500 calories for women, so it is most appropriate to consume about 500 calories for breakfast.

Extended data:

Need heat

Daily calorie requirement of adults = basic calorie required for basic metabolism of human body+calorie required for physical activity+calorie required for digestion of food.

Heat required for digesting food = 10% x (minimum heat required for basic metabolism of human body+heat required for physical activity)

Daily caloric requirement of adults = 1. 1 x (minimum basal caloric requirement for basic metabolism of human body+caloric requirement for physical activity).

Male: 9250- 10090KJ

Female: 7980-8820 kJ

Note: The daily calories provided by food should not be less than 5,000-7,500 kilojoules, which is the least energy to maintain normal life activities.

A simple algorithm for basic calorie metabolism of human body

Female: basic calories = weight (kg) x 9

Man: Basic calories (calories) = weight (kg) x 10.
