Please note: Supplements are generally not FDA tested or approved. Some supplements can interfere with medications and/or cause side effects. Do not delay seeking medical attention for medical concerns by taking supplements without medical advice. Please discuss any and all supplements you take with your health care provider. whey-protein-muscle-builing People often think, “If I eat more protein, I’ll get bigger muscles.” But is that really true? Let’s break it down simply. Muscles don’t just grow because you stuff yourself with protein shakes. They grow when you give them the right amount at the right time—and when you actually use them through exercise. Protein is like the building blocks of your body. Imagine Lego pieces. Each piece connects to make something bigger. Protein works the same way for your muscles. Without enough of it, your body struggles to build and repair. With the right amount, your muscles get stronger and recover faster.  

Why Protein Is Important

  • Muscles break down during workouts.
  • Protein repairs those muscles.
  • That repair process makes muscles grow back stronger.
Think about it: if you build a sandcastle and the waves knock it down, you need more sand to rebuild. Protein is your “sand.”

What Are Smart Shakes?

Today's innovative shakes are designed with intention and scientific rigor, offering a sharp contrast to the single-nutrient protein shakes of years past. Instead of focusing on muscle recovery, these shakes incorporate a broader spectrum of health-promoting nutrients, from vitamins and minerals to plant-based adaptogens and live cultures. A GLP-1 protein shake perfectly represents this trend, crafted to support wellness through thoughtfully selected ingredients that go well beyond protein content. Such shakes often claim to help with satiety, energy, and metabolic health, catering to those wanting more than simple calorie replacement. This evolution in the shake market is about more than just ingredients—it's a response to busy, health-conscious lifestyles. People juggling careers, family, and fitness often need a fast, efficient breakfast, lunch, or post-gym recovery solution. Innovative shakes meet this demand, acting as versatile, portable meal options. Importantly, they appeal to athletes and anyone who values proactive health measures, including students, professionals, and parents. Instead of settling for generic "one-size-fits-all" blends, individuals seek shakes with functional ingredients promising tailored benefits, from immune support to cognitive clarity to sustainable energy throughout the day.

  [caption id="attachment_65178" align="aligncenter" width="500"]eggs-protein-eggwhites Photo by Felicity Tai[/caption]   Protein is a fundamental nutrient that plays a vital role in weight loss and appetite regulation. Understanding how protein affects these areas can help optimize dietary strategies for better health outcomes. From influencing hunger hormones to boosting metabolism, protein’s role in the body is multifaceted and powerful.

How Protein Influences Appetite

One of protein’s standout benefits is its ability to enhance feelings of fullness, also known as satiety. When you consume protein-rich foods, your body releases appetite-suppressing hormones such as peptide YY and GLP-1, which signal your brain to reduce hunger. In contrast, diets low in protein may leave individuals feeling hungrier, leading to overeating or increased snacking. This is why many weight loss programs emphasize incorporating high-protein meals and snacks to curb cravings and improve adherence to calorie-controlled plans.

Plant-based proteins have garnered significant attention in nutrition studies due to their significant health benefits and ability to protect the body from chronic diseases. Given this, it's reasonable to assume that the growing popularity of plant-based diets, which promote healthy and sustainable lifestyles, provides ample evidence of their crucial role in maintaining health and preventing heart disease, obesity, and various cancers. A vital synthesis of important discoveries has influenced the growing significance of plant proteins in health. It demonstrates metabolic benefits, aids in the prevention of disease, and has ramifications for the environment and public health.

Health Benefits of Plant Proteins

Plant proteins offer significant metabolic benefits that may reduce the risk of disease, as highlighted by McCarty in his study in 1999. He observed that, in contrast to animal proteins, which may cause an excessive release of insulin, plant proteins stimulate the production of glucagon. This mechanism effectively regulates blood sugar levels, thereby reducing the risk of obesity, heart diseases, and certain cancers, such as breast and colon cancer. Furthermore, plant proteins promote improved hormone balance, which reduces inflammation, a key cause of chronic illnesses, and helps lower lipid levels and fat storage.

Beavers Assistant Professor, Department of Health and Exercise Science Department of Biostatistical Sciences Wake Forest School of Medicine Winston-Salem, NC Dr. Beavers[/caption] MedicalResearch.com Interview with: Kristen M. Beavers PhD, MPH, RD Assistant Professor, Department of Health and Exercise Science Department of Biostatistical Sciences Wake Forest School of Medicine Winston-Salem, NC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Weight loss recommendation for older adults with obesity is controversial, in part because overall weight loss is accompanied by loss of muscle and bone, which may exacerbate age-related risk of disability and fracture. Identification of interventions that can preserve muscle and bone while promoting fat loss should maximize cardiometabolic benefit, while minimizing potential harm to the musculoskeletal system. This randomized controlled trial was originally designed to test whether a higher protein, nutritionally complete meal plan could preserve lean mass and mobility in older adults undergoing a six month intentional weight loss program. Four publications have resulted from this study: * “Effect of an Energy-Restricted, Nutritionally Complete, Higher Protein Meal Plan on Body Composition and Mobility in Older Adults with Obesity,” Journals of Gerontology: Medical Sciences, published online in advance of print June 21, 2018 * “Effect of a Hypocaloric, Nutritionally Complete, Higher-Protein Meal Plan on Bone Density and Quality in Older Adults With Obesity,” American Journal of Clinical Nutrition, published online in advance of print Jan. 9, 2019 * “Effect of Intentional Weight Loss on Mortality Biomarkers in Older Adults With Obesity,” Journals of Gerontology: Medical Sciences, published online in advance of print Aug. 20, 2018 * “Effects of a Hypocaloric, Nutritionally Complete, Higher Protein Meal Plan on Regional Body Fat and Cardiometabolic Biomarkers in Older Adults with Obesity,” Annals of Nutrition and Metabolism, published online in advance of print Feb. 11, 2019 Across the four publications, we found that: * Participants lost about 18 pounds, most of it fat (87 percent), and preserved muscle mass. The control group lost about half a pound. * Even when participants lost weight, they maintained bone mass. In fact, trabecular bone score, a measure of bone quality which predicts fracture risk, seemed to improve. * Fat was lost in the stomach, hips, thighs and rear, which is important for preventing or controlling cardiometabolic diseases such as diabetes and stroke. * Participants’ score on the Healthy Aging Index, which measures biomarkers that predict mortality and longevity, improved by 0.75 points.

MedicalResearch.com Interview with: ""Trash Fish" Sustanable Seafood Dinner" by Edsel Little is licensed under CC BY-SA 2.0Nuno Mendonça RD, PhD Campus for Ageing and Vitality Newcastle‐upon –Tyne United Kingdom  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Very old adults, those aged 85 and older, are the fastest growing age group in most western societies and are more likely to develop disability. Dietary protein is a sensible candidate because it may slow decreases in muscle mass and functional decline with aging. Although we know that protein intake is, on average, lower in older adults (a mean of 66 grams per day) compared to younger adults (a mean of 91 grams per day), research exploring protein intake and disability progression in very old adults is limited. We found that our participants from North-East England had four different disability trajectories between the ages of 85 and 90: a) a constant very low disability trajectory (difficulty with none or 1 activity of daily living (ADL))  over the 5 years; b) a low disability trajectory (difficulty with 2 ADLs) that steadily progressed to mild disability (5 ADLs); c) a mild disability score (4 ADLs) at 85 that increased to moderate disability (10 ADLs) by age 90; and d) a moderate disability score (9 ADLs) at baseline that progressed to severe disability (14 ADLs) after 5 years. We found that those with higher protein intake, especially those at or above 1 g per kg of body weight per day (70g of protein per day for a 70 kg person), were less likely to belong to a worse disability trajectory.

MedicalResearch.com Interview with: Mingyang Song Sc.D, research fellow Clinical and Translational Epidemiology Unit and Division of Gastroenterology MGH and Department of Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous studies have been focused on the amount of protein intake, while little is known regarding the health effect of different food sources for protein intake. In this study, we found that high animal protein intake was associated with higher mortality, whereas high plant-based protein was associated with lower mortality. Replacement of animal protein with plant protein was associated with lower mortality. Overall, the findings support the importance of food sources for protein intake for long-term health outcomes.

Gemelli Catholic University of the Sacred Heart Senior Collaborator in the Nurses' Health Study Brigham and Women's Hospital Channing Division of Network Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: In our study, we looked at the association between dietary intake of different sources of protein (vegetable, dairy and non-dairy animal), potassium (a marker of fruits and vegetables) and their interaction and the risk of forming kidney stones. We looked at their interaction because some protein is a source of acid, whereas fruits and vegetables are a source of alkali, thus their relationship could potentially impact acid-base status and in turn the risk of stones by modifying the metabolism of calcium and other elements such as urine citrate and uric acid. We found that the risk of forming stones depends not only on the amount of protein but also on the source, with no risk associated with intake of vegetable and dairy protein, and a modestly higher risk for excessive non-dairy animal protein; on the other hand, intake of potassium was associated with a markedly lower risk. Interestingly, the interaction between intake of protein and potassium, the so called net acid load, was also associated with higher risk of forming kidney stones, suggesting that the effect of acid intake is modulated by that of alkali and vice versa.

Phillips Ph.D., FACSM, FACN Department of Kinesiology, McMaster University, Canada Exercise Metabolism Research Group – Protein Metabolism Research Lab Director, Physical Activity Centre for Excellence Medical Research: What is the background for this study? What are the main findings? Prof. Phillips: During weight loss with diet only people lose both muscle and fat and muscle. The long-term health consequences of losing metabolically active muscle versus fat are not likely to be beneficial. In the context of this study we thought perhaps the preservation of muscle would also be important in very active young men. We wanted to see whether when men were in a very large energy deficit (40% less energy than they required) higher protein (2.4 g/kg/d) could preserve muscle mass and still result in increased function (strength) and fitness. Our results show that during a marked energy deficit that consumption of 2.4 g protein/kg/d was more effective than consumption of a diet containing 1.2 g protein/kg/d in promoting increases in LBM (1.2 vs 0.1kg increase) and losses of fat mass (-4.8kg vs. -3.5kg) when combined with a high volume of resistance and anaerobic exercise.

Anestis Dougkas, MSc, PhD Food for Health Science Centre Lund University Lund, SwedenMedicalResearch.com Interview with: Anestis Dougkas, MSc, PhD Food for Health Science Centre Lund University Lund, Sweden MedicalResearch: What is the background for this study? Dr. Dougkas: There has been an increased interest in the macronutrient profile of diets and meals as a factor that influences appetite. Dietary protein is considered as the most satiating macronutrient, yet there is little evidence on whether the effects observed are attributed to the protein or to the concomitant manipulation of carbohydrates and fat. The aim was to examine the effect of consumption of beverages varying in macronutrient content on appetite ratings, energy intake and appetite-regulating hormones. MedicalResearch: What are the main findings? Dr. Dougkas: Increased protein content suppressed more average appetite than carbohydrate and fat with a more pronounced effect of protein intake on subjective ratings of prospective consumption. Protein was also the most influential macronutrient for postprandial glucagon like peptide-1 (GLP-1, an appetite- suppressing hormone) response. This appetite-suppressing effect of protein was independent of the changes in fat and carbohydrates.

Moore, DSc, MPH Co-Director, Nutrition and Metabolism Assoc Prof of Medicine Preventive Medicine & Epidemiology Department of Medicine Boston University School of Medicine Boston, MA 02118 Medical Research: What are the main findings of the study? Response: Our data were derived from 1,361 adults (aged 30-54 years) enrolled in the Framingham Offspring Study and showed that men and women who consumed higher amounts of protein had lower blood pressures (both systolic and diastolic blood pressures) after four years of follow-up. We then followed them for an average of about 11 years and found that those who consumed the most protein (approximately 103 g/day) had about a 40% lower risk of developing high blood pressure than those consuming about half that amount. These beneficial effects were even more pronounced when higher protein intakes were combined with high fiber intakes.

Answer: That muscle wasting occurs rapidly and early in critical illness, with up to 2-3% loss of muscle mass per day. This is related to the numbers of organs failed, and is made worse by the degree of acute lung injury, and increased protein delivery. Muscle wasting is the result of both decreased muscle protein synthesis and increased muscle protein breakdown. In addition 40% of these patients developed muscle necrosis over the study period.
