Tue w/ Thomas #3 - ARE CARBS REALLY EVIL?

The thing about carbs is that they cause a change in your body's chemistry.

A spike in blood sugar levels from fast digesting carbs will normally cause in increase in insulin release. I say normally because with repetitions of these spikes, your body will become insulin resistant and not react as quickly. These releases of insulin cause your body to stop burning fat. 
If your goal is fat loss this becomes a problem.

Now here's the other thing about carbs...
If you cut them out completely you're brain won't be able to function right and you'll feel lethargic and pretty out of it.
Your body will also adjust to being in a calorie deficit if you keep your calories too low for too long and your metabolism will drop. This is why you can't just starve yourself thin. I mean, you can if you want to do it the long, hard, unhealthy way, but a better strategy would be to employ something known as carb cycling.
This is a technique in which your carbs are kept very low for a 3 days to a week or 2 before allowing your body to have a day of higher carbs to refeed your glycogen stores. This allows you to burn fat much more effeciently without letting your body go into starvation mode, essentially tricking your body into keeping your metabolism reving.

There are a few popular strategies for this that depend on how disciplined you are.
I have found 3 days low / 1 day high and then repeating to be the easiest to follow.
Some are able to go a week or 2 before raising the carbs back up. This takes dedication, and for some like myself, impractical due to the nature of my workouts.

The bottom line is NO, carbs are not evil!

The key is to eat good whole food sources of low glycemic value carbs. Look for things such as sweet potatoes, brown rice, whole oats, and quinoa. These are the type that our body will burn slow and not cause a sudden spike in insulin release.

Here is a list I have personally compiled of carbs I deemed to be ok. You will notice some are actually faster digesting carbs, but they do have a place in my client programs. The list can give you a good guideline to bring to the grocery store.

Body Type / Macro Ratios - Some people are more sensitive to carbs (Endomorphs) and need to watch them more closely and some people need lots of carbs to function well (Ectomorphs). If you are an Endomorph, or someone who gain fat easily, your macro nutrient ratios will differ from that of an Ectomorph who will have a high carb tolerance.
Mesomorphs, or people who classify themselves as someone who have a naturally muscular build will typically find a ZONE based macro most beneficial (30% Protein , 30% Fat, 40% Carbs).
Endomorph - (35% Protein , 40% Fat, 25% Carbs)
Ectomorph - (30% Protein , 15% Fat , 55% Carbs)

These are guidelines that obviously would need to be adjusted based on the individual's goals and workout intensity/frequency)

Timing when you eat carbs is an important topic to address. The optimal time to eat your carb meals is after or around your workout. Your body is much better situated to use those carbs in the best way during that time.
If you are sensitive to carbs, (Endomorph) you are going to want to make sure your starchy carbs are limited to only around the time of your workout. The rest of the day you should only be eating veggies and lean proteins.

Mesomorphs can eat starchy carbs at breakfast and also around their workout, and Ectomorphs can get away with more carbs at every meal.

Also be aware that the higher your carb content for the day or meal, the lower your fat intake should be and vice versa. This is important to keep your body from storing fat.
