The amount of calories needed in the morning is based on an individual's daily caloric intake. Many experts agree that morning is the best time for the largest meal of the day, according to About.com. A person requiring 1,200 calories a day eats perhaps 400 of those calories at breakfast.
Research current as of 2014 has found that a daily diet with three meals and two snacks is beneficial for many people. For a 1,200-calorie daily diet, consume 400 calories at breakfast, and allot 300 calories each for lunch and dinner. Eat two 100-calorie snacks between these meals. People who eat large dinners need to lower their caloric intake earlier in the day so as not to overeat.
