Weight loss is a very simple equation - be cautious of anyone who tries to complicate weight loss.
Here is the big secret...ready?
What you eat must be equal to or less than what you burn! That means you should eat within your caloric range AND exercise. That's it!
Of course getting to your goal body composition isn't that easy when life gets in the way. That's why it is important that you employ a trainer who can not only keep you on track but also guide you through the labyrinth of the diet-exercise-life balance.
