Does Whey Really Help with Weight Loss – Part 2

If whey does what the data suggests it carries out in the above, that must be the most effective method for making the most of the impacts of whey on food (calorie) intake on subsequent meals in addition to the other metabolic effects covered. If exercising, the schedule may be different nevertheless and individuals should follow the pre and post nutrition recommendations made in my ebook “Muscle Building Nutrition” or suggestions easily discovered on the ‘net via the numerous sports nutrition and bodybuilding associated web sites.

It appears elements in whey – some of which have been pointed out above – are thought to act synergistically with calcium to enhance body structure (Zemel MB. Function of calcium and dairy products in energy partitioning and weight management. Am J Clin Nutr. 2004 May; 79( 5 ):907 S-912S.).

The scientists taken a look at twenty-nine “highly stress-vulnerable topics” and 29 “reasonably stress-invulnerable” topics using a double blind, placebo-controlled study style. The study individuals were exposed to experimental stress after consuming a diet improved with either alpha-lactalbumin (found in whey) or sodium-caseinate, another milk based protein.

Astonishingly, the ratio of plasma Tryptophan to the other amino acids evaluated was 48% higher after the alpha-lactalbumin diet than after the casein diet plan! This was accompanied by a reduction in cortisol levels and higher prolactin concentration. Possibly essential and pertinent to the average individual reading this post, they discovered “reduced depressive feelings” when test subjects were put under stress.

Other possible benefits whey may confer to the dieter is improved blood sugar policy (Frid AH, Nilsson M, Holst JJ, Bjorck IM. Impact of whey on blood sugar and insulin reactions to composite breakfast and lunch meals in type 2 diabetic subjects. Am J Clin Nutr. 2005 Jul; 82( 1 ):69 -75.) which is yet another essential area in managing appetite and metabolism.

Needless to say, Increased brain serotonin levels are related to an enhanced capability of individuals to manage stress, whereas a decline in serotonin activity is related to anxiety and stress and anxiety. Elevated levels of serotonin in the body typically lead to the relief of anxiety, as well as considerable decrease in discomfort sensitivity, stress and anxiety and stress. It has also been theorized that a diet-induced increase in tryptophan will increase brain serotonin levels, while a diet designed for weight-loss (e.g., a diet plan that reduces calories) might result in a reduction of brain serotonin levels due to lowered substrate for production and a decrease in carbohydrates.

The system responsible for increased fat loss found with dairy-based calcium versus nondairy calcium has not is not totally comprehended however scientists taking a look at the concern thought “… dairy sources of calcium considerably attenuate weight and fat gain and accelerate weight loss to a higher degree than do supplemental sources of calcium. This augmented result of dairy items relative to supplemental calcium is likely due to additional bioactive compounds, including the angiotensin-converting enzyme inhibitors and the rich concentration of branched-chain amino acids in whey, which act synergistically with calcium to attenuate adiposity.”

Elevated levels of serotonin can cause relaxation and decreased anxiety. Low serotonin levels are associated with low mood, increased anxiety (hence the existing appeal of the SSRI drugs such as Prozac and others), and poor cravings control. This is an extremely abbreviated description of all the functions serotonin carries out in the body – a lot of which have yet to be totally illuminated – however a complete description is beyond the scope of this article.

So exactly what is the practical application of all this details and how does the dieter put it to good use? Being the cravings suppressing results of whey appear to last approximately 2-3 hours, it would seem best to stagger the consumption throughout the day. For example, breakfast may be 1-2 scoops of whey and a bowl of oatmeal, and maybe a few scoops of whey taken between lunch and dinner.

Although the above would probably be the major mechanisms by which whey could help the dieter, there are several secondary effects of whey that may help in weight-loss. For instance, whey’s results on serotonin levels. Serotonin is probably the most studied neurotransmitter given that it has been discovered to be associated with a vast array of mental and biological functions. Serotonin (likewise called 5-hydroxytryptamine or 5-HT) is involved with state of mind, stress and anxiety, and appetite.

Many people on a minimized calorie consumption in an effort to lose weight find they are typically ill tempered and more anxious. Reductions in serotonin might be partially to blame here. One current research study (The bovine protein alpha-lactalbumin increases the plasma ratio of tryptophan to the other big neutral amino acids, and in vulnerable topics raises brain serotonin activity, decreases cortisol concentration, and enhances mood under stress. Am J Clin Nutr 2000 Jun; 71( 6 ):1536 -1544) took a look at whether alpha-lactalbumin – a major sub fraction discovered in whey which has an especially high tryptophan content – would increase plasma Tryptophan levels as well decrease anxiety and cortisol concentrations in topics under severe stress considered to be vulnerable to stress.

Taken in seclusion, none of these studies are so engaging that individuals should go out and use whey as some kind of weight loss nirvana. However, taken as an overall image, the bulk of the research study appears to conclude that whey might in truth have some special effects for weight-loss and should be of fantastic use to the dieter. More research studies are plainly required however.

They concluded that the “Consumption of a dietary protein enhanced in tryptophan increased the plasma Trp-LNAA ratio and, in stress-vulnerable topics, improved coping ability, probably through modifications in brain serotonin.” This impact was not seen in the sodium-caseinate group. If other studies can confirm these findings, whey might turn out to be yet another safe and reliable supplement in the fight against depression and stress, in addition to reduced serotonin levels due to dieting.

Lastly, calcium from dairy items has been found to be associated with a reduction in body weight and fat mass. Calcium is thought to influence basal metabolism as intracellular calcium manages fat cell (adipocyte) lipid metabolic process in addition to triglyceride storage. It’s been demonstrated in a number of studies the superiority of dairy versus non-dairy sources of calcium for improving body composition, and the whey fraction of dairy possibly the key.

* Cortisol levels (which were assessed prior to and after the stressor).

* Prolactin levels.

* Changes in mood and pulse rate.

* Diet-induced modifications in the plasma Tryptophan and its ratio to other big neutral amino acids.

Conclusion

Although there is a long list of hormonal agents associated with hunger policy, some of which have actually been mentioned above, serotonin appears to be an essential player in the video game. In basic, experiments find increased serotonin availability or activity = minimized food usage and reduced serotonin = boost food consumption. If whey can selectively increase serotonin levels above that of other proteins, it might be really helpful to the dieter.
