What are the Best Carbs toHelp you Build Muscle or Lose Fat? Fast Carbs VS Slow Carbs

More than often, you’ll get this response: “Stay away from simple carbs and focus on complex carbohydrates, since they digest slowly and provide your body with a constant stream of energy”.
I can’t tell you how many “fitness-experts” give this response to their clients on a regular basis. Of course it seems to make sense, but there is actually some science suggesting otherwise.
Many people believe that as long as a carbohydrate digests slowly, it should keep your blood sugar stable and make it less likely for you to gain fat.
But the truth of the matter is that structuring your nutrition program around “slow-digesting carbohydrates” is actually not an effective way to get the nutrition you need.
There are actually 4 primary reasons why this is the case. Let’s go ahead and take a closer look…





Here are 4 of the main reasons why this is so…

First, carbohydrate absorption speed is based on the glycemic index, which is a highly flawed tool for bodybuilding nutrition.

The glycemic index (GI) is a chart that ranks carbohydrates from 0 to 100 based on how quickly or slowly they raise blood sugar levels in a 2-hour period after they are consumed.

Here’s the problem: GI rankings are based on the glycemic effects of specific foods that are consumed isolated and in a fasted state.

Aside from first thing in the morning, you’ll never be consuming your carbohydrates in a fasted state. And even then, a typical bodybuilding nutrition plan always combines carbohydrates with fats and proteins. Consume your carbohydrates as part of a complete meal and the glycemic response can be dramatically altered.

Second, the glycemic ranking of a carbohydrate source is not necessarily indicative of its effects on insulin.

Certain “fast carbs” may produce a smaller insulin release, while certain “slow carbs” may produce a larger insulin release. You can compare the “insulin index” to the glycemic index to see this for yourself.

For example, brown pasta has a GI ranking of 70, while its insulin score is only 40. An orange has a GI ranking of 39, but an insulin score of 60.

Third, carbohydrates are not the only food source that produce an insulin release.

Most people don’t even know this, but most protein-rich foods that you find in a typical bodybuilding nutrition plan elicit just as high (or higher) an insulin response as most of the carbohydrate sources.

Fish has an insulin score of 59, which is nearly identical to that of brown rice, and 20 points higher than brown pasta. Beef has an insulin score of 51, about equal to rye bread and nearly half that of a white potato.

When you factor in the insulin index, and the fact that most proteins cause a significant elevation in insulin levels, the whole notion of controlling insulin by eating “slow carbs” goes straight out the window.

Lastly, even in the rare case that you did consume a high glycemic/high insulin producing carbohydrate source alone in a fasted state, it still won’t affect you to any meaningful degree.

Unless you have a pre-existing health condition, your body is incredibly efficient at keeping your blood sugar levels and insulin levels within a fairly precise range.

Slam 300 grams of pure sugar first thing in the morning, and yeah, you might run into some problems. But in a practical, real-world scenario this is never going to happen, and having your blood sugar/insulin increase to higher than normal levels isn’t going to have any measurable impact on your muscle building or fat burning goals.

At the end of the day, the issue of “fast carbs” vs. “slow carbs” has no practical relevance to your bodybuilding nutrition plan.

All you really need to focus on is 2 things:

1) Getting the bulk of your carb intake (80-90%) from high fiber, minimally processed sources. This includes foods such as oatmeal, rice (brown or white), potatoes, pasta, pita, ezekial bread, fruits and vegetables.

2) Consuming your carbohydrates as part of a complete meal.

As long as you do these 2 things, you’re good as gold, and there’s no need to analyze the fast carbs vs. slow carbs issue any further.
