Does Whey Really Help with Weight Loss – Part 1

As whey protein likewise affords high levels of complete, biologically available and complete amino acids, with minimal additional calories from carb and fat, it may remain in itself among the more ideal food options to consist of in weight-loss and lean-body-mass maintenance nutrition strategies. Based upon the above understandings, it may be best to ingest whey protein without competition from other protein sources, and to not slow down the assimilation of the amino acids with synchronised consumption of large amounts of fiber or fat, if our desire is to generate a more instant result on state of mind, sleep, behavior and appetite.

The amino acid “building block” to serotonin is tryptophan. It is essential to appreciate that the ratio of tryptophan to big neutral amino acids (LNNA) identifies tryptophan schedule to the brain. These LNNA are tyrosine, phenyalanine, and the branched-chain amino acids (BCAAs), specifically leucine, isoleucine and valine, all which take on tryptophan to cross the protective blood-brain barrier to enter the brain.

These information strongly support the concept that overweight individuals may do well by supplementing with tryptophan. As both low levels of tryptophan and its availability to the brain vis-?- vis tryptophan/LNAA ratios tend to lead to below-optimal serotonin levels, which is subsequently conductive to carbohydrate yearnings, bad sleep, low self-confidence and state of mind, and impulsive habits. Such a notion is not without sensible argument.

Regrettably, the FDA continues what many convincingly argue is its unjustified prohibition of tryptophan as a dietary supplement. Perhaps not unassociated is the skyrocketing prescription of selective serotonin reuptake inhibitors (SSRIs), perhaps the most familiar being Prozac. Maybe the lack of “natural” competition from tryptophan becomes part of this multibillion-dollar-per-year “success” story!

An option, and possibly even superior, method may be to make use of premium whey protein blends. Such whey protein blends have an abnormally rich supply of tryptophan and a greater ratio of tryptophan to BCAAs compared with other proteins, such as soy or casein. The intake of as little of 10 grams of carb at any one time starts the release of insulin, with its potential salubrious effect on tryptophan uptake by the brain and its neurophysiology.

In addition, it is necessary to be conscious that insulin, which is released as the result of ingesting carbohydrate, is, as any serious body contractor understands, anabolic, implying growth-promoting. Insulin facilitates the elimination of protein, particularly the fragrant and branched-chain amino acids, from the bloodstream, to be mostly directed to muscle tissue. This function of insulin assists eliminate these rivals to tryptophan’s crossing the blood-brain barrier.

One such brain messenger is serotonin, which is known to affect state of mind, promoting a relaxed feeling that Julia Ross, MD, maybe best refers to as “lightness” to support deep sleep and melatonin production, and to impact appetite, particularly for carbohydrates.

Our present understanding of the physiology of cravings is insufficient. However, we understand that there are various endogenous brain messenger compounds (neurotransmitters and neurohormones) that result, among other things, mood, memory, relaxation, focus, and cravings.

A better appreciation of the relationship of these brain messenger chemicals to their nutritional foundation, especially the amino acids, may be a crucial factor in endeavors to regulate hunger and thus facilitate medical efforts to attain and maintain ideal lean body mass.

A recent paper in the American Journal of Clinical Nutrition 2 reported that both the plasma tryptophan concentrations and ratios of tryptophan to LNNA were low at all times throughout and after successful weight-loss programs that kept lean body mass. The authors also kept in mind that the overweight participants were typically insulin-resistant. Such reduced insulin activity may be an irritating consider ongoing low plasma ratios of LNNA to tryptophan levels. Plasma concentrations of tryptophan, as such, were also reported to be low in dieting clients prior to, during and after effective weight loss. Inning accordance with the authors, Breum et al., these two observations and their prospective concomitant results on state of mind and hunger may be part of the reasons for regression after diet-induced weight loss!
