It is better to eat six meals a day. Breakfast at 7: 00 am, brunch at 10 in the morning, lunch at 1 0 in the afternoon, dinner at 4: 00 pm, snack at 7: 00 pm, bedtime snack at 10 in the evening, 530 calories for breakfast, lunch and dinner, and 350 calories for other meals. Of course, three meals a day is also possible. There is no accurate scientific basis for how many calories are needed for each meal. What matters is the calories per day/week/month, not the calories per meal.
After 2650 calories per day for two weeks, 500 calories per day will be added, reaching 3 150 calories per day. Measure your weight every week. If you gain weight, eat the same calories. If you don't gain weight, you need to add another 500kcal calories next week, and keep doing this until you reach a satisfactory weight.
