The first thing to understand is that the perfect diet does not exist! The perfect diet is the one that works for you, and you WILL need to investigate. And you will need to adjust over a period of time. So forget that any diet could be the perfect diet, but personalize your diet!
The second thing that you need to keep in mind is that it’s not all about calories. A calorie coming from a doughnut is doing something different to your body than a calorie coming from an egg for instance. The effect on your metabolism, on your hormones and on your health are immensely different. To make sure you are successful you need to balance out hormones so that hunger and cravings are in check. Because in the end it is hard to win the battle for fat loss on willpower alone. So it is good to find out your ‘trigger foods’ and analyze your energy levels and how you react to certain foods. Focusing more on protein, fiber, good fats and water, instead of sugar and other foods that have a high caloric but low nutritional value, will help you beat cravings.
Here are some guidelines that might help you find that almost perfect nutrition plan. You can jump in anywhere depending on your current habits.
