Calories definitely matter - but they matter in a few ways, not just as a matter of
over consumption. If you're coming from low fat / restricted calorie dieting then they matter even more.
Eating far too many calories than you burn will not result in fat loss, but eating far
too little wont either. What is so wonderful about LC is that it allows you to eat real food and to eat until you are satisfied. This is largely due to the fat content. Fat is satiating - it makes you feel full. It is also self limiting, there is only so much of it you can eat. Sit down and try to eat a stick of butter and you'll see what I mean
LCing helps to set right the metabolic imbalances that low fat / high carb / restricted calorie eating creates. At first you'll find that calories really
do not matter. Simply eating the right foods, in the right combinations (protein and fat), creates an environment in favour of fat loss. It's almost like magic, but it isn't. It's biochemistry.
Calories tend to come into play more as you get closer to your goal and you have to tweak to get the last few lbs to come off. For some this never happens. Many things will factor into it. As you get healthier, leaner, fitter you become more active, allowing you to eat more than before. As you become healthier and your insulin resistance is repaired your metabolism is raised, allowing you to eat more than before. And as you eat adequate protein you help your body build and repair lean tissue, raising your metabolism and allowing you to eat more than before.
Try a few searches on this site on "BMR" (basal metabolic rate) and "Metabolism" for more information on this subject - it has been discussed at great length.
Finally, do you know how many calories you
are eating? LCing robs us of our appetites at first, we are not hungry like we used to be - often we take this to an extreme, thinking
less is better when it is not. If you feel the need, keep track of calories for a while to keep tabs on just how much (or how little) you are eating; you'll notice trends. Eating higher calorie a few days often resutls in whooshes (losses of fat and water) for many. Mixing things up calorie wise is called 'calorie cycling' and it is the basis for many weight loss programs - it keeps the body from thinking "diet", which is a good thing.
In the end you don't really need to count calories - you just need to ensure you're getting your minimum protein requirement and that you're eating every few hours to keep metabolism raised.
It really is a new way of thinking, not just eating.
