Why You Should Supplement Fast Carbs After Exercise
Supplementing with fast carbs after exercise helps ensure that your efforts don’t go to waste
Fast Carbs
Fast carbs have a high glycemic index
They are absorbed and digested quickly, leading to a rapid spike in insulin levels.
A high insulin level benefits you by significantly increasing protein synthesis
This can shift you from a muscle-wasting state to a muscle-building state
Slow Carbs
Slow carbs have a low glycemic index
They are made of long chains or branched chains of simple sugars, which must be broken down into simple sugars by enzymes during digestion and are absorbed slowly
This prevents dramatic fluctuations in blood sugar levels.
If you feel tired and sleepy after exercise, it’s because your glycogen stores have been depleted
Eat slow carbs before exercise and fast carbs after exercise
This helps with muscle synthesis and prevents muscle loss
Consuming fast carbs after exercise stimulates insulin release, which counteracts cortisol and promotes muscle repair
After exercise, cortisol levels rise, and cortisol promotes the breakdown of proteins, muscles, and fats
Consuming protein (meat, eggs, dairy, legumes) post-exercise provides the building blocks for muscle repair
Consuming fast carbs (white rice, white bread, bananas) stimulates insulin secretion and rapidly replenishes depleted glycogen stores
Carbohydrates are also essential for fat loss
Many people mistakenly believe that not eating after exercise, or avoiding carbs, will prevent their hard work from going to waste
Excessive energy intake is a major cause of fat accumulation! Eating appropriately after exercise won’t waste your efforts
If you don’t consume carbs after exercise, your body will break down muscle protein for energy, leading to muscle loss → decreased basal metabolic rate → making fat loss even harder
At this point, you would have to work harder with minimal results
How Much Should You Consume After Exercise?
Consume 0.5g/kg of body weight in fast carbs within 30 minutes after exercise
Whether your goal is weight loss, muscle gain, or increased strength, you should not only consume protein but also an appropriate amount of carbohydrates after training
