Have you ever wondered why certain people can eat bowls of pasta, rice, or other high carbohydrate meals - whilst others thrive under a lower carbohydrate diet? As much as people boil food down to the calories that are inside them, they only tell half the story.
We are all biologically individual, and this is especially important when it comes to your choice of eating. Every person reacts differently to our two primary energy sources; fat and carbohydrates, and this is largely dependant on their ethnic background. This is why following someone else's diet will not work in the same way for you.
The only solution here is to be your own best expert, and this takes some time. Test, tweak and experiment with the amount of carbohydrates and fats you consume - to find what works for you and your biological individuality.
