These topics are getting more complex, so it becomes really challenging to communicate the message effectively on carousels. I’ll be making YouTube videos on everything we discuss here, so stay tuned for that! Today, we talk about one of the biggest mistakes in bodybuilding nutrition is reducing carbohydrates to either “energy” or “fat gain.” That’s an extremely incomplete way of looking at them. Under high training demands, carbohydrates become one of the body’s main regulators of: - muscular output - glycogen availability - ATP regeneration - fatigue resistance - recovery capacity - nutrient partitioning And that’s exactly why high-level hypertrophy training is so heavily carbohydrate-dependent. When you train hard enough, especially with high intensity close to failure, the body rapidly burns through muscle glycogen to regenerate ATP fast enough to sustain repeated muscular contractions. As glycogen availability drops, force production begins to fall, repetitions decrease, fatigue accelerates, and recovery becomes progressively impaired. That’s one of the reasons why people often feel: flat, weak, drained or unable to sustain performance during demanding training blocks when carbohydrate intake is poorly managed. But carbohydrates do much more than simply support ATP production. Every gram of glycogen stored inside skeletal muscle pulls several grams of intracellular water with it. This cellular hydration increases muscular fullness and contributes to the local metabolic stress associated with hypertrophy adaptation. Then we have insulin sensitivity: This is one of the most important concepts in sports nutrition. High insulin sensitivity helps direct carbohydrates toward skeletal muscle for glycogen restoration and recovery rather than inefficient nutrient partitioning and excessive fat storage. And this is where carbohydrate quality, timing, and digestion speed start becoming important. Simple carbohydrates digest rapidly and are extremely useful around training when the body demands rapidly available glucose. Complex carbohydrates digest more slowly and provide more stable glucose availability throughout the day. Fiber plays a completely different role by slowing digestion, stabilizing blood glucose, improving satiety, and helping maintain gastrointestinal health during high food intake phases. Timing also matters differently depending on the demand placed on the body: For most athletes training once daily, total carbohydrate intake across the day is still the biggest factor for glycogen restoration and performance. But when training volume becomes extreme, sessions are dense, or recovery windows become shorter, peri-workout carbohydrate timing starts becoming far more important for maintaining blood glucose, delaying fatigue, and accelerating glycogen restoration. That’s why carbohydrates should not be viewed as “good” or “bad” like many creators portray them! They are performance tools and should be consumed for maximum training output and muscle growth. Plus, the greater your performance and the more muscle you build, the more carbs you’ll need to consume as well. Once you understand that system, carbohydrate management starts making much more sense! Sources: • Burke et al. (2017) — The Journal of Physiology • Ivy et al.
