Most of the digestion of carbohydrates takes place in the mouth. Chewing carbohydrates well is extremely important. Third, pay attention to the times you eat. Eating breakfast is a very good idea, but as the word says you are breaking a fast of 8 to 12 hours. A meal after a fast should be very light like fruit.
Fruit is the most easily digested food possible.
I would not recommend a heavy protein or fatty breakfast in the morning. Your brain needs some carbohydrates in the morning to function. Low fat dairy products and legumes have proteins, but they are not difficult to digest. You should finish eating your proteins by 2 or 3 p.m. Therefore, lunch should be the heaviest meal.
