If you eat eggs in moderation at night, you won't get fat. If you eat eggs before going to bed, it may have a great impact on your health, because the cholesterol and protein you eat at this time are not easily digested and absorbed by your body. For most people, eating eggs after dinner will make them fat. However, for people in some special circumstances, such as those who exercise at night, or those who are in poor health and want to eat less and eat more meals, it is ok for them to eat eggs at night if reasonable arrangements are made.
