My girlfriend is losing weight. I want to make him a nutritious breakfast. It's better to be simple, the materials are easy to get and nutritious. And you can lose weight, the most important thing. ... To tell the truth, morning is very important for dieters. You should eat as much as possible. The calorie intake should account for most of the three meals. If it is simpler, oats are naturally better, instant oats. Just rinse it with boiling water. Better yet, eat an egg. Eat one or two fruits. Also eat some staple foods, such as whole wheat bread.
