Ask The Science Chick: Is The Anabolic Window Real?Ah, the anabolic window—easily one of my favorite windows, and easily one of the most hotly debated topics in sports nutrition over the last several years. I admit that when I missed my anabolic window in grad school, I used to preach the importance of consuming adequate amounts of carbs and protein within 45 minutes of finishing a workout. Jump forward five years, and my point quanto custa clembuterol liquido view has missed my anabolic window While I still think it's important to fuel your body post-workout, I no longer believe you somehow miss out on an windwo for growth if anaoblic don't eat immediately after your last set. Why the change of heart?
Maximize muscle growth by using the post workout anabolic window
Ah, the anabolic window—easily one of my favorite windows, and easily one of the most hotly debated topics in sports nutrition over the last several years. I admit that when I was in grad school, I used to preach the importance of consuming adequate amounts of carbs and protein within 45 minutes of finishing a workout.
Jump forward five years, and my point of view has changed While I still think it's important to fuel your body post-workout, I no longer believe you somehow miss out on an opportunity for growth if you don't eat immediately after your last set. Why the change of heart? For one, research methods have drastically improved, and we're armed with better information. Early studies often used subjects in a fasted state to look at the effects of nutrient timing on changes in body composition, strength, and muscle size.
Because fasting itself will put your body in a catabolic state, eating immediately after a workout is crucial for promoting muscle protein synthesis and glycogen storage. But unless you train at 5 a. Eating as few as 20 grams of protein as part of your pre-workout meal can significantly elevate the delivery of amino acids to your muscles for up to hours post-workout.
It certainly doesn't hurt to throw back a protein shake immediately after your workout, but you can still gain a substantial amount of strength and size even when delaying post-workout nutrition.
If you start your training session more than four hours after your last meal, you definitely want to consume grams of protein immediately after your workout to help reverse the catabolic state in your body and maximize muscle growth. On the other hand, consuming a small pre-workout meal before you train can delay the timing of your next meal, which might come in handy if you have to rush to a meeting, quickly get ready for work, or run a few errands.
Another issue with some of the older studies is the lack of dietary control. Several early studies controlled only for protein and carb intake immediately before and after training, paying little attention to what was being consumed the rest of the day. Rather than focusing on this imaginary window of special growth, plan your meals so that you consume grams of protein every few hours, and consume adequate amounts of carbs throughout the day to keep your energy levels high in the gym.
This water-soluble dietary fiber has a long history of use in herbal mixtures and foods like tofu and shirataki noodles, but it's now available as an over-the-counter supplement for weight loss.
Like other soluble fiber—oats, guar gum, pectin, and psyllium—glucomannan works by absorbing liquids in the stomach, causing it to increase in size and delay the exit of food from your stomach. This in turn can help to increase satiety, reduce body weight, reduce the rise in glucose levels of a post-carb meal, and increase the elimination of cholesterol-containing bile salts.
If you want to give glucomannan a try, I recommend taking 1 gram with about 8 ounces of water before breakfast, lunch, and dinner. Several clinical trials have investigated the impact of glucomannan on body weight, blood glucose levels, and cholesterol, and have found it to be beneficial for the most part.
I do want to stress that these studies have been done using clinical populations. Patient populations included those with type 2 diabetes, those who were overweight or obese, and those with high cholesterol and high blood pressure values.
It's tough to say whether an apparently healthy individual would experience the same benefits, but it does appear to be safe and tolerable, with flatulence and diarrhea being some of the more common side effects.
You might want to refrain from using before a date or social outing! Like most weight-loss methods, glucomannan may be more effective when combined with a reduced-calorie diet and a training program that includes both resistance exercise and moderate cardio.
Artificial sweeteners like aspartame, saccharin, stevia , and sucralose are commonly used to sweeten food and drink without adding calories. Their history of use has been accompanied by debate and disagreement about whether their consumption might increase the risk of becoming overweight and obese.
Before we get into the effects of low-calorie sweeteners on your waistline, I do want to discuss their safety. There are numerous reports and websites that claim artificial sweeteners are toxic to your body because they're a chemical.
Just because something's labeled as a "chemical" doesn't make it inherently bad for you. Take, for example, lecithin, pectin, guar gum, and propionic acid. These are all common chemicals found in foods and have no reported side effects. You probably didn't even know you were consuming them.
Put simply, there's no available data on human subjects showing that consumption of artificial sweeteners can lead to diseases like diabetes and cancer. It's safe to say that if you include them in your diet in moderation, you won't grow a third eye or an extra limb.
Some argue that substituting artificial sweeteners for the "real deal" may cause you to crave additional sugary snacks, or cause you to increase your energy intake at the next meal. But the question at hand is whether artificial sweeteners cause you to crave more sweets and hinder your weight-loss goals. However, a recent review article published in the International Journal of Obesity found that both calorie intake and body weight decreased with the consumption of artificial sweeteners relative to sugar.
A review article from observed similar findings, with the authors concluding that substituting a low-calorie sweetener in place of a regular-calorie version can result in a moderate loss of body weight. Furthermore, it may be a useful dietary tool to improve compliance with weight-loss or weight-maintenance dietary programs. Drinking liquids flavored with low-calorie sweeteners has also been shown to have zero impact on subsequent calorie intake when compared to water. For some, the exposure to sweetness may be a bit dangerous, because it could create a preference for sweet foods, but multiple studies have shown that acute exposure to sweetness—say, drinking water flavored with Crystal Light—can decrease the desire for additional sweet items.
What's more, a study published in the American Journal of Clinical Nutrition found that subjects drinking a beverage flavored with a low-calorie sweetener reduced their consumption of dessert items compared to those drinking water. You may dislike artificial sweeteners and see them as the root of all evil, but if you're looking for some help to curb your cravings, or just want to add a little flavor to your otherwise boring bottled water, you're more than safe adding artificial sweeteners into your diet!
