1 boiled egg about 70g, heat 100kcal.

1 slice of whole wheat bread is about 36.0 grams, with a calorie of 89 kcal.

A cucumber is about 100g, and the calorie is very low, only 15kcal.

If it is to lose weight, the normal calorie consumption of a day also needs 1200 calories, which depends on the weight base.

But the minimum intake should not be less than 800 calories. According to the minimum intake, the recommended energy intake in the morning is 30% of a day, that is, 400 calories. The total calorie of your breakfast is only 204 calories, which is not enough. If you eat too many calories at noon or at night, you will be more likely to become obese.

According to this calculation, your daily calorie intake is seriously insufficient and you must lose weight. I suggest you eat more coarse grains and vegetables, which are not high in calories, but it is better to lose weight by increasing gastrointestinal peristalsis.
