The main reason many people fail to get that flat stomach they want is that they do lots of exercise but neglect to change their eating habits and hence, their results remain hidden beneath a layer of fat.Exercises are only a part of what it takes to get a flat stomach. Correct eating habits are the most important part.The first healthy eating tip towards a flat stomach is to eat more often to speed up your metabolism (the process by which your body breaks down and utilises food that you eat). You should eat five-six meals a day to increase your metabolism. This can be done by making your meals smaller and adding healthy snacks between meals.When we eat, our bodies are designed to store fat for the future when we might have less food available. If your body is starving it does everything to store fat after every meal and your metabolism slows considerably.On the other hand when your body feels you have plenty of food available, your metabolism increases and you store a lot less fat.This is why starving yourself (and diets that require you to eat less than 1500 calories a day) will never work in the long run as a way of losing fat.Your metabolism will slow down and when you go back to eating like you did before the crash diet, you gain a lot more fat than you lost.So, increase the frequency of your meals and increase your metabolism to burn more calories after each meal and to store less fat.Doing this will also help you feel full for longer periods and thus, prevent you from feeling hungry during the day.The second healthy eating tip towards a flat stomach is to start eating early and don't eat late at night. You should eat breakfast as soon as possible when you wake up, this will start your metabolism that slowed during the night.If you don't eat breakfast your metabolism will slow even further as your body reacts to the hunger. Stop eating at least two hours before you go to bed. This will allow your food to digest properly and help your body rest and recuperate better from the previous day.Third healthy eating tip has to do with what you should eat and what you should not eat. This is simple. Don't completely change your diet all at once. Start by eating the same foods you are used to and only the healthier versions of those. Eat whole meal and wholegrain bread instead of regular white bread.Eat whole grain cereals (eg brown rice, oats, unpolished maize products etc), low fat milk products, egg whites as well as lean meat and tuna. Counting calories you should consume.Source: The Mirror
