6 Incredible Clean Carbs Sources To Build Muscle And Improve Performance

Carbohydrates are the primary fuel source for your brain, body, and overall athletic performance. But not all carbohydrates are created equal. Clean carbohydrates sources or complex carbohydrates provide the long-lasting sustained energy you need for prolonged workout periods, such as running, cycling, and high-intensity functional training. Not only that but, clean carbs help you build more muscle and optimize workout recovery. The question is, what carbohydrates are best for building mass, optimizing body composition and performance?

The Problem With Simple Carbs

Chances are you’ve had a snack or chugged a sugary carb drink before a workout or long run and find yourself gassed-out mid-way through your training. This is because simple carbohydrates and supplements such as maltodextrin, dextrose, and cyclic dextrin, spike your insulin levels, which can attribute to low blood sugar leaving you feeling tired, fatigued, and lethargic.  

Let me paint a picture for you. Most people, athletes included will consume a sugary energy drink or carbohydrates an hour or two before their training session, to get that mid-day pick-me-up, when their energy hits a wall. This infuses a vicious cycle, that we call the Blood Sugar Roller Coaster. 

After the sugary drink or simple carb is ingested, your body is flooded with an abundance of carbohydrates, surmounting in a short boost of energy, followed by a devastating crash and burn. Once this happens, your body dispels the hormone insulin, to regulate the amount of sugar (glucose) in your bloodstream. When insulin is released by the pancreas, it disperses the sugar out of your blood into the liver, muscle, and stores it as body fat. When the blood sugar is removed, it results in low-blood sugar translating to low energy levels.  

This is the reason why you have mood swings, feel hungry all the time, or get fatigued and have low energy. Insulin levels and blood sugar all depend on the type of carbohydrates you consume. When you hear certain carbs being ‘high’ on the glycemic index, it means that they will spike blood sugar and insulin quicker than other types of carbohydrates.  

What You Need Are Complex Carbs

Complex carbs digest much slower than simple carbohydrates, due to their longer-chain molecular structure. Complex carbs are also sugars, but they do not spike blood insulin, keeping your blood glucose levels stable, and provide a long-sustained energy release. These types of carbohydrates or clean carbs work best for prolonged training, improving endurance, building more muscle mass, and optimizing body composition. Complex carbs slow the absorption of sugar, slowing down digestion, which results in lower cholesterol levels and keeping you fuller for a longer period of time. No Blood Sugar Roller Coaster with complex carbs. So, what are the best clean carbs for building more muscle and performance?
