Bagels are a popular preworkout food, but if you look at their glycemic index, it's a whopping 103. The corresponding insulin response will not only decrease energy stores for exercise, but it will also prevent fat breakdown.
more than 24 hours.1314 In other words, the body is primed for the acceptance of protein for muscle maintenance and growth. Equally important is the need for consuming plenty of carbohydrates. After you work out, your body is somewhat depleted of its glycogen stores. Remarkably, studies have shown that high-glycemic carbohydrates are the preferred source for replenishing the body's energy stores after training.15 Not only does that result in greater storage for recovery and subsequent workouts, but it also significantly decreases muscle breakdown.16
Postworkout meals should contain about twice the normal amount of carbohydrates and protein, and you should eat them immediately following exercise. For example, if you were eating five meals per day and 3,000 calories, your postworkout meal would be approximately 1,000 calories, while the other four meals would average 500. Postworkout meals should also contain a larger percentage of protein than preworkout meals to keep up with the body's elevated protein synthesis rate.
People make a lot of mistakes with the preworkout meal. How many fitness enthusiasts eat a bagel before exercise? Due to their alleged energy benefits, bagels are a popular preworkout food, but if you look at their glycemic index, it's a whopping 103. The detrimental effects of eating such high-glycemic carbs before training are monumental. The corresponding insulin response will not only decrease energy stores for exercise, but it will also prevent fat breakdown. Fortunately, low-glycemic foods have much the opposite effect. They improve exercise performance without significantly compromising energy stores after a workout.917 That, in turn, leads to enhanced recovery and accelerated progress.
A suggested meal plan [such as the one at the back of this book] isn't perfect. You'll need to tinker in order to determine the ideal diet for you. Building a physique takes time, dedication and consistency, and losing or gaining weight should be a gradual process to ensure the right kind of changes. Don't rush it, stay focused and consistent, and you'll move ever closer to physical excellence.
