Weight loss expert Jay Robb offers The Best Whey Protein Powder. Made with a Whey Isolate. Studies Show Supplemental Whey Helps People Drop Body Fat: There are at least two studies where scientists examined whey protein supplementation and weight loss. NITRO-TECH RIPPED is the ultimate protein + weight loss formula. NITRO-TECH RIPPED is the ultimate protein + weight loss. WHEY PROTEIN Supplement: Usage, Dosage, Side Effects & Benefits - Examine. Sources and Composition. Sources. Whey is one of two protein fragments of dairy protein, the other being casein. Whereas casein consists of approximately 7. Whey is the water- soluble fragment, and is extracted from casein during the process of coagulation and syneresis (explained on the casein processing page, the two fragments separate after a coagulant is added). Whey is the liquid portion that is seen as 'by- product' from the process of making cheese that consists of mostly caseins, and the technical definition of the whey is . Whey, protein, concentrate, isolate, whey protein, whey isolate, whey concentrate, health, food. Is Whey the Best Protein Powder for Weight Loss? Whey protein powder is sold in health food and vitamin stores and it's also available as an. Since whey protein isolate is not an option for you. Whey Protein May Be Helpful for Weight Loss. Study Suggests Whey Protein Offers More Weight Loss Help Than Soy Protein. By Brenda Goodman, MA. The Best Whey for Weight Loss. Whey protein isolate is best for dieters.Although the majority of commercially sold whey is derived from cows (bovine whey), whey can also be derived via any animal that produces milk through breast tissues: buffalo. When milk is met with a coagulating agent, the part that coagulates is cheese; the part that does not (liquid part) are the wheys. Composition (Peptides)The amino acids in whey protein can be formed into different orders, and create unique bioactive peptides. Beyond differences in amino acid composition, different protein sources can have different effects through their bioactive peptides. The peptides in whey are the following, and the four (4) bolded peptides are those with most practical relevance (due to their high contents in whey). It is the largest protein in whey at 5. Da. A category of small Y- shaped proteins (4 peptide chains) bound by disulfide bonds, with the (2) light chains weighing approximately 2. Da each. One immunoglobulin classified as . Those that are grouped as protein structures are 'peptides' and may have unique properties based on the sequence (order) of amino acids that make them up. Bioactive peptides in whey are one of the two possible reasons for differences between protein sources (the other being total amino acid composition) The bioactive peptides in whey (strings of small- chained amino acids that are left over when larger proteins are digested) tend to be more involved with immunity when compared to other protein sources, mostly through the immunoglobulins and other large proteins. Composition (Amino Acids)All of the aforementioned peptides are constructed from a collection of amino acids, and the amino acid profile of whey can confer some benefit after bioactive peptides are digested. The numbers below are averaged from multiples sources found here for Whey Protein Concentrate. At 5% hydrolysis. Sulfur containing amino acids drop from 7. Differing trends are also seen with Glycine, which drops from 5. Valine, which spikes from 1. Histidine which rises from 7. All other amino acids tend to fluctuate around their normal levels, and this study used an enzymatic hydrolysis via Protamex (Bacillus proteinase, broad specificity for hydrophobic amino acids) at 1. AU/g. Composition (Other)Some other molecules can be found in whey protein. These are commonly referred to as impurities if the person labeling them sees them as bad and as additions if no bias is attached. This list has things inherently included with the whey fraction of dairy, and excludes any additions that a company may add to their proprietary blends or personal Whey Protein products. Molecules that may be found in the Whey fraction that are not amino acids in nature are: Hippuric Acid at 2. Rennet Whey (0. 0. L- Cysteine and Glutathione. Glutathione is an endogenous (made and stored in the body) anti- oxidant enzyme that is made of amino acids, with L- Cysteine being the rate- limiting enzyme. Populations that may be deficient in glutathione levels and show promise with either whey or isolated L- Cysteine supplementation include cancer patients. These include Cystic Fibrosis. A cysteine deficiency is not universally recognized due to it being an non- essential amino acid (can be synthesized from methionine, an essential amino acid) but appears to have some manner of deficiency syndrome associated with it, at least indirectly via glutathione. L- Cysteine and Hydrogen Sulfide. Hydrogen Sulfide (H2. S) is a gaseous byproduct (frequently remarked to be the causative smell of eggs. A circulating H2. S pool of 1. 0- 1. M exists in the human body. Whey Concentrate. Concentrate is the least processed form, and is 3. Whey Isolate. Isolate is defined as being more than 9. Whey Hydrolysate. Hydrolysate is protein that is enzymatically and acid pretreated to reduce the particulate size even further and is the fastest absorbed. Hydrolyzed protein is protein that cleaves peptide bonds, and reduces large quaternary proteins down to peptides and free amino acids. Due to this, special bioactive effects of quaternary protein structures in whey (immunoglobulins, bovine serum albumin, lactalglobulin and lactalbumins) may not apply to hydrolyzed whey, depending on the di- and tripeptides left over. They have either equal health benefits, or hydrolysate may confer less (or at least different) health benefits due to breaking of large peptides prior to digestion. One study that gave participants Whey Isolate or Whey Hydrolysate and tested performance at baseline and then 6 hours later noted that only the Hydrolysate group recovered power in such a short time frame, although no differences existed in muscle soreness. Ultrafiltration. Ultrafiltration is another filtration through a physical gradient, where whey passes through and smaller compounds are allowed to pass and larger molecules get caught. Exclusion of a- lactalbumin in the whey is actually a cost- effective way of isolating a- lactalbumin for usage in infant formulas, research, or for fortification purposes. Amino acid ratios remain the same, but are much higher per gram of product due to the act of concentration. Mineral and ash content are reduced. Microfiltration. Microfiltration is the same process of ultrafiltration, but with a more restrictive gradient. Rather than a polyethersulfone barrier, microfiltration tends to use a polyvinylidene fluoride (PVDF) membrane which allows molecules between 0. M through, a more restrictive membrane relative to ultrafiltration. Stomach Digestion. Whey appears to resist coagulation in the stomach and pass on relatively quickly to the intestines. Coingested nutrients may also influence gastric emptying rates. In one intervention where nitrogen content, energy density, osmolarity, liquid volume, and caloric content were all matched; there were no apparent differences in gastric emptying between whole whey and casein as well as their hydrolysates. Intestines and Absorption. Whey protein appears to be less effective, relative to casein protein, at slowing intestinal motility rates. Serum. Whey protein seems to spike in the blood approximately 4. Blood Pressure. Whey protein has been investigated for its ability to reduce blood pressure due to the presence of several ACE- inhibiting peptides derived from both alpha- lactalbumin and beta- lactoglobulin. Changes in lipoproteins with this study design are also insignificantly different, although there was a significantly lesser release of triglycerides after the consumption of whey relative to both casein and glucose. Artherosclerosis and Lipids. Consumption of a meal with whey protein (relative to gluten, cod, or casein protein) appears to result in a lesser spike in CCL5. Glycogen. One intervention in rats using Whey protein hydrolysate noted that, relative to concentrate and isolate as well as Branched Chain Amino Acids, that hydrolysate was more effective in increasing glycogen when measured 2 hours after ingestion. Diabetes. L- Cysteine, the amino acid present in whey's immunoglobulins, is seen per se as potential adjunct therapy for Diabetes type II. Intestines and Colon. In general, whey protein is seen as beneficial to the lining of the intestines, especially in clinical settings where intestinal function is impaired. Liver (Hepatic)A pilot study has been conducted on whey protein supplementation and its interactions with non- alcoholic fatty liver, and 2. ALT down from 6. 4. U/L to 4. 5. 8. 9U/L; similar reductions in AST and GGT) and reduce liver fat deposits while improving glutathione (an endogenous anti- oxidant enzyme) status. Kidneys. Although not specific to whey, protein in general (and most commonly an excess of protein) has been said to cause renal (kidney) damage to healthy humans. This claim has been the subject of many reviews, and conclusions tend to cluster around 'no adverse effect of protein' with intakes up to 2. The one study to specifically isolate whey protein is confounded with Conjugated Linoleic Acid and Creatine (also usually said to harm kidneys yet hasn't been shown to) but found no abnormalities over 5 weeks with 3. There is an apparent increase in glomerular filtration rate (GFR) with higher protein diets and acute protein ingestion, with an inverse decrease in GFR with low protein diets; these fluctuations of GFR are not associated with kidney abnormalities if the kidneys were healthy to begin with; but signify adaptation to new dietary intake. Although there are . The most commonly cited is acceleration of chronic kidney disease, where an inherent reduction of glomerular filtration rate seen during disease pathology (indicative of the failing potential of the kidney) appears to be accelerated when dietary protein is raised. These populations may be already placed on a low protein diet by a Medical Doctor, and should speak to a physician before using Whey Protein. Neurology. 8. 1. Movement control and Seizures. A component of whey protein known as Alpha- Lactalbumin has been investigated for its neurological roles due to its high tryptophan content. This study reported that there was no significant effect on myoclonus movements while anti- depressive effects and improved sleep quality were seen, with half the patients opting to remain on treatment after the study concluded. Immune Cell interactions. The two main whey proteins, a- lactalbumin and . How to Lose Weight With Whey Protein Shakes. When it comes to protein supplements, whey protein makes a good choice that's easily absorbed and rich in all the essential amino acids. They may make a healthy addition to a weight- loss plan, but whey protein shakes alone won't magically melt away those unwanted pounds. To benefit from a diet that includes protein shakes, control your overall calorie intake and add resistance training to your plan. Before you start downing whey protein shakes, consult your doctor or a dietitian for weight- loss tips and shake suggestions. Whey protein supplements may not be your favorite weight- loss aid, but they can help you lose fat instead of muscle, according to a 2. Nutrition Journal. This study found that a whey protein meal- replacement shake helped a group of overweight and obese individuals following a reduced- calorie diet lose more body fat than muscle. Why is it important to retain muscle tissue? Because muscle burns more calories than fat tissue - - 6 calories per pound versus 2 calories per pound, respectively, according to research published in the American Journal of Human Biology in 2. When you lose weight, you typically lose both muscle and fat, which causes your metabolism to slow and may make it harder for you to slim down. Drinking a whey protein shake may help prevent some muscle loss, which may make it a little easier for you to continue to lose fat. Whey protein may also help you control hunger, according to a 2. European Journal of Clinical Nutrition, which may make it easier for you to stick with your diet. This 1. 2- week- long study compared the effects of whey protein versus casein, also a milk protein, and a carbohydrate supplement on hunger levels in a group of overweight and obese participants, and found that the whey protein worked better at keeping away the desire to eat than the other two supplements. While whey protein shakes may help you reach your dieting goal, this won't work if the shakes contribute excess calories. Weight loss requires a negative calorie balance, which means eating fewer calories than your body needs. If 1 pound of fat contains 3,5. For example, using an online calorie calculator, a 4. There are several types of whey protein shakes, so pay attention to total calories per serving. Calories from any source count, especially when you're trying to shed pounds, so count them in your daily total. Calories and protein in whey protein supplements, primarily available in powder form, vary among brands - - some popular whey shake products range from 1. In addition to helping preserve muscle while you're losing weight, combining a whey protein shake with resistance training may help you build more muscle. Whey protein contains the right balance of amino acids needed to support muscle growth, and is a good source of leucine, which is critical for muscle building. When you add muscle to your frame through resistance training, it helps your body burn calories and improves your physique. Plan to train your muscles two or three times a week on nonconsecutive days. Use free weights, weight machines or resistance bands for all your major muscle groups on each resistance- training day. Weights should be heavy enough that by the last rep, usually eight to 1. Most whey protein powders are flavored, although you can get them plain. Mixing with water saves calories, but consider blending with low- fat milk for flavor, additional calories and carbs, if needed. This is especially important if you're drinking your whey protein shake after weight training. For 3. 0 minutes following a workout, your body is at its peak for muscle building, and it's recommended that you consume a snack containing both protein and carbs within that time frame. Most whey protein powders are not rich in carbs, with only up to 6 grams of carbs per scoop, and blending a cup of nonfat milk with your whey protein adds 1. If you're lactose intolerant, avoid whey protein concentrate and instead use shakes that contain whey protein isolate or hydrolysate. Also, if you have a medical condition such as kidney or liver disease, consult your doctor before adding protein shakes to your daily routine.
