It's the quality of your morning meal... If your breakfast is healthy and includes whole-grains and a source of proteins, then it can sustain you for 3 to 4 hours until snack time! On the other hand, if you have a high sugar-refined carb breakfast, such as plain kaak, some biscuits, plain cake or white bread sandwich, then you'll digest it quickly and feel hungry after a short time.
Now, when you skip breakfast entirely, your body will feel hungry from within, and when your hunger pangs start, you'll reach out for anything near (normally an unhealthy snack) or if you make it till lunch, you'll have an over-sized meal! So the best scenario here is to have a mix of whole grains such as whole-grain cereals, oats, or whole-grain bread, which are rich in fiber, combined with a source of protein such as a glass of low fat milk, low fat cheese, labneh, eggs or turkey.
