Post-workout “anabolic window of opportunity”
See a Problem?
Glycogen needs to be replenished, and carbohydrate combined with protein is the most effective choice. Although nutrient timing appears best suited for competitive athletes, its strategies can benefit everyday exercisers as well. Proper fuel stores carbohydrate and protein can enhance any workout, and the anabolic characteristics of the postexercise phase hold true for dedicated step, indoor cycling and boot camp enthusiasts alike.
Advising clients to consume a balanced snack 2—3 hours prior to exercise and to consume a carbohydrate- and protein-containing snack or meal following the session helps them advance their workout, enhance their glycogen stores and recover successfully. As suggested by Kleiner, calories may be unnecessary during the workout if weight loss or maintenance is the objective Eating a balanced, varied diet with adequate protein and carbohydrate will enhance training sessions and workouts; and taking advantage of the hormonal milieu of anabolic players following activity will promote recovery and improve muscle integrity.
As with previous sports nutrition recommendations, the take-home message is that the active body benefits from proper nutrition. Endocrinology Before engaging in conversation about eating in response to the ebb and flow of hormones, it is helpful to understand the hormonal players and their response to exercise.

Theres other good things to like it has a few pages on different things like protein and what it does and hormones and like testosterone. This is a book aimed more for an experienced lifter. By EdgarOmar on May 17, Highly recommended for beginners. The information is simple and straightforward.
By Troy Hollings on January 11, So, as all good reviews start, I have never written a review for a product on Amazon, but this book was so good I had to. Ever since I first discovered weight training all I have cared about was gaining muscle. All my friends wanted to get "stronger" or the mythical, metrosexual "toned.
While this book would definitely be helpful for people looking to get "strong" or "toned", it is the first scientific take on how to gain muscle I have ever read. I took a kinesiolgy class in college, but everything we did was related to performance; my teacher couldn't conceptualize the idea that someone would just want to get super huge.
That being said, this book gives super in depth, scientific information on how to gain muscle. It talks about using different nutrients to create an anabolic environment in the body and really backs it up with scientific data. I didn't know how powerful certain hormones like cortisol and insulin are, and how much of an effect they have on the body.
I loved that Harry Potter books, but this book was even better. If you are a fitness nerd, who has a basic understanding of bodybuilding nutrition, BUY this book and take it to the next level.

Surely everybody knows that breakfast is the most important meal of the day! Our bodies are therefore primed to use nutrients and especially carbs more effectively than at other times of the day.
Our glycogen levels, especially those in our livers, are running low. Plus, some evidence does suggest that we use carbohydrates more effectively in the morning than at night. In fact, both choices are just fine. The only support comes from correlational research X and Y happen at the same time , and not causal research Y happens because of X. In a recent American Journal of Clinical Nutrition paper, researchers analyzed dozens of studies to look at the relationship between breakfast and body weight.
Because, again, most of this evidence is observational. When examining research that actually controls for all the variables and looks at cause and effect, the results are pretty mixed. In other words, breakfast looks to be beneficial for some of us. But not for others. The strongest of this evidence suggests that breakfast is most important for malnourished or impoverished children. By now, my grandparents must be groaning. However, the truth is, most of this research has been done in animals, with only a few conclusive human studies.
Finally, a recent study offers a fascinating postscript to the breakfast and weight loss question. The groups whose habits and routines were changed were the ones with the most substantial weight loss. The people who normally ate breakfast and skipped it during the study lost weight. And the people who normally skipped breakfast and ate it during the study lost weight. Ultimately, this study showed that when people become more aware of their intake, they get better results — whether they eat breakfast or skip it.
There is no right or wrong choice, as long as whichever choice you make is actually helping you improve your health, performance, and body composition.
For years dietitians and nutritionists myself included thought that the best approach to splitting up your daily food intake was to eat small meals frequently throughout the day.
In college I ate eight times per day. From early research we assumed that eating often would speed up the metabolism, help control the hormones insulin and cortisol, and manage the appetite. However, a recent review in the Journal of the International Society of Sports Nutrition , and other lines of evidence, suggest otherwise:. As long as we eat the right foods in the right amounts, meal frequency seems to be a matter of personal preference.
You can eat lots of small meals each day i. Or you can eat a few big meals each day i. There could be psychological differences, mind you. Which is why I highly recommend listening to your own body.
Experiment with fewer meals if you eat more frequently. And more meals if you eat less frequently. And, of course, expert coaching can really help fast track this process. Make no mistake, nutrient timing is a complex subject. Nutrient timing can be helpful.
Or it can add layers of unnecessary complexity. It all depends on the context. At that point in the game, there are more important things to do. Some people are already very lean, compete at the elite levels of physique or athletics, and have nailed down items 1 to 5 above.
These athletes often engage in training or events lasting longer than two hours at a stretch, where added carbohydrates, electrolytes, and a little protein can go a really long way. For most of us, most of the time, nutrient timing demands extra effort, requires additional planning, and adds dietary complexity… with minimal return.
For some, the PW and AT set-up simply works for them. Being results-oriented coaches, that is cool with us. Our experience with thousands of clients, and new scientific evidence, show us: For most people, nutrient timing is not a main priority. This chart, adapted from Alan Aragon, explains. The nutrition world can be pretty complex. But, at PN, we like to keep it simple. We like clients to think less about food decisions. Focus on mastering 1 to 4.
