Protein is one of the most common nutritional concerns raised by male clients.¹ It is often tied to goals related to fitness, body weight, healthy aging, or managing chronic diseases.¹ For healthcare providers, addressing protein-related questions is an opportunity to support both immediate and long-term health for male clients.² This article reviews evidence-based strategies for counseling men, with an emphasis on tailoring recommendations to age, lifestyle, and health motivators.

How Much Protein Is Enough?
The recommended dietary allowance for protein is 0.8 g/kg/day, but some researchers hypothesize that the recommendation, made by the Institute of Medicine in the early 2000s, may not be enough for all populations.³ This baseline prevents deficiency but may not optimize health and evidence supports increased intakes of 1.2–2.0 g/kg/day for active males, older adults, or those with chronic disease.^3-5 Daily distribution likely matters as much as total intake. Consuming 20–30 g of protein at each meal (three to four per day) at a minimum, keeping in mind that individual needs will vary, more effectively stimulates muscle protein synthesis than skewing intake heavily toward dinner, as is common in a more traditional Western dietary pattern.⁶ To promote muscle repair and hypertrophy, researchers recommend consuming protein pre-, during, and post-workout.⁷ The amount of protein intake for athletes or males with muscle gain aspirations will vary, with some studies indicating as much as 1.6-2.2g/kg/body weight.⁷

It is important for healthcare providers to be prepared to clarify dietary myths. More protein does not automatically lead to increased muscle mass.⁸ Gains occur when protein intake is paired with strength training.^7,8 Providers who specialize in sports nutrition can help guide their patients in how much protein to consume based on their training, goals, and unique body requirements, while reinforcing that balance and consistency, not excess, drive results.⁷

Protein in Food vs Supplements
Whole foods should be emphasized as the baseline of protein intake because these foods come along with vitamins and minerals that support nutritional status. Lean meats, poultry, fish, eggs, dairy products, legumes, soy foods, nuts, and seeds provide high-quality protein, along with essential nutrients.⁹ Plant-forward diets, including vegetarian and vegan, can meet protein needs without additional supplementation, though health care providers can assess diet quality to ensure nutrients like omega-3 fatty acids, calcium, vitamin D, iodine, B12, zinc, and iron are being met.^10-13

Protein supplements can be useful when increased requirements make meeting needs through food alone challenging. Whey and casein are well-studied, while pea, soy, and other plant-based blended proteins offer alternative options. In a randomized 84-day trial of sedentary adults (N=85), pea protein supplementation produced muscle strength and mass gains comparable to whey protein when combined with weekly resistance training. Whole-body muscle strength improved by 16.1% in the pea protein group (p = 0.01) and 11.1% in the whey protein group (p = 0.06), with no significant differences between groups in body composition, product perception, or tolerability.¹⁴ Whey protein has been studied extensively and is rich in the amino acid leucine, tied to muscle protein synthesis and anabolic growth.⁸ A large meta-analysis (N=78 randomized controlled trials; 5,272 middle-aged and older adults) undergoing resistance training and comparing six protein sources (whey, milk, casein, meat, soy, peanut). Whey protein ranked highest for enhancing muscle mass (SMD 1.29; SUCRA 0.86), handgrip strength (SMD 1.46; SUCRA 0.85), and walking speed (SMD 0.73; SUCRA 0.84).¹⁵

Providers should remind clients that supplements are optional tools, not substitutes for balanced meals. It’s important to choose a high-quality protein powder supplement from trusted brands with a long history of being in the market. Patients may ask for recommendations about product quality, such as grass-fed whey, a product without preservatives or other fillers, and/or organic ingredients.

Many active males or athletes may inquire about creatine, L-carnitine, or branch-chain amino acids (BCAAs) for muscle building in addition to protein supplementation.⁹ Creatine monohydrate is the most common and scientifically backed ergogenic aid, helping to fuel muscles, increase lean tissue mass, and accelerate recovery from muscle damage and injuries.^7,16 Clinical trials support its benefit, and standard dosing is 3-5g per day, though some athletes require more.⁹

L-carnitine is a compound made from the amino acid lysine that plays a role in energy metabolism and supports bone tissue maintenance and growth.¹⁷ In a randomized controlled trial (N=68 overweight or obese adults), participants who combined 100mg/day L-carnitine supplementation with a 3x per week, 12-week exercise program (brisk walking and interval training) showed the greatest benefits for both bone and muscle health when compared to control, exercise-only, or supplement-only groups. The intervention group experienced greater improvements in muscle strength and power based on dominant knee extension and flexion torque and average power (p < 0.05).¹⁷

BCAAs are three essential amino acids (leucine, isoleucine, and valine) that are considered “essential” – the body cannot make them on its own, and they must be consumed in the diet.¹⁸ They are found in protein-rich foods and play key roles in muscle energy, repair, and growth.⁹ Commonly supplemented in athletes, they may help improve recovery and performance.^9,18 In a 6-month trial of 100 recreational weightlifters, BCAA supplementation (leucine 500 mg, isoleucine 250 mg, valine 250 mg/d) improved recovery and performance compared to the placebo group. Men in the study achieved a 10% increase in bench press strength.¹⁸

Counseling Male Clients
When counseling male clients, it is important to recognize that gender shapes health behaviors and engagement with care.^2,19 Research shows that conformity to traditional masculine norms, such as nondisclosure, wanting to be rational, and the need for control, can limit men’s willingness to seek help or fully participate in healthcare.² Rather than placing the responsibility solely on men to adapt, healthcare systems and providers should adopt gender-responsive approaches that take into account these dynamics to engage men better, improve communication, and ultimately support more effective health outcomes.^2,19

Effective counseling requires tailoring both content and delivery. Men often prefer clear numbers, such as grams per day, over broad dietary advice. Visual tools, such as sample meal plans or plate models, can help translate abstract targets into concrete choices. Some studies have shown that using informal language may enhance health messages, perceived as more “down to earth”.² Motivators such as strength, performance, increased energy, faster recovery from workouts, or better long-term physical function may help recommendations resonate.¹⁹

Practical strategies are essential. Encourage clients to keep portable protein options, such as Greek yogurt (if refrigeration is an option), jerky, nuts, protein bars, shakes, and powders, readily available. Meal prepping, such as cooking extra chicken or beans for salads and wraps, supports consistency and ease of meeting dietary needs. 

Key Takeaways for Providers
Protein is central to many men’s health goals, but intake needs are a common question male clients may bring to their healthcare providers. Providers can improve outcomes by setting evidence-based targets collaboratively with their clients, taking into account their age, activity level, and dietary patterns. Providers can use the Orgain® protein calculator to determine their patients’ unique needs: https://orgain.com/pages/protein-calculator

Emphasizing balanced distribution and reinforcing food-first approaches with supplements as optional support is the foundation of nutrition education for this population. Counseling is most effective when numbers are clear, examples are practical, and recommendations are tied to motivators that matter to each client.
