The Hidden Health Risks of Today’s Most Popular Diets Among Men, Experts Warn
June marks Men’s Health Month, a time to spotlight preventable health risks and support early intervention for men’s well-being.
According to the American Cancer Society, 1 in 8 men will be diagnosed with prostate cancer in their lifetime. Dietary patterns play a major role, and experts at Ben’s Natural Health warn that trending diets like carnivore, keto, intermittent fasting, and unbalanced vegan plans may overlook the very nutrients that support testosterone, reduce inflammation, and protect
1. Carnivore Diet: All Meat, No Micronutrient Backup
Eliminating plant foods also removes antioxidants, fiber, and phytonutrients shown to reduce inflammation and support hormone balance.
A 2022 meta-analysis published in Frontiers in Nutrition found that higher consumption of red and processed meats was significantly associated with increased prostate cancer risk, while vegetable intake was protective.
“Diets without any plant buffers can leave the body vulnerable to oxidative stress and inflammation,” the team explains. “Tomatoes, leafy greens, and cruciferous vegetables are known to offer protective compounds.”
2. High-Protein “Gym Bro” Diet: Muscle Gains, Micronutrient Losses
Gym-focused diets heavy in chicken, red meat, and processed shakes often leave little room for healthy fats, fiber, or mineral-rich foods.
Although exact global percentages vary, many studies confirm that very low-fat or unbalanced high-protein diets can affect testosterone production. Research in Nutrition (2021) suggests that significant changes in macronutrient intake may impact sex hormone levels, depending on fat content and diet duration .
“Micronutrient deficiencies in zinc, magnesium, and healthy fats are common when the focus is only on protein macros,” the experts warn.
3. Intermittent Fasting: Hormonal Trade-Offs
Time-restricted eating plans like 16:8 can promote fat loss—but without proper nutrient intake, they may also reduce testosterone and stress the endocrine system.
A 2022 study published in Nutrients found that intermittent fasting reduced testosterone concentrations in men, although it did not affect SHBG levels. The researchers concluded that fasting may have hormonal impacts that should not be overlooked, particularly in males with obesity.
“Men need to plan their intake during eating windows to ensure they’re not losing out on key minerals like zinc and selenium,” says the team.
4. Keto Diet: Fat-Fueled, Fiber-Starved
While keto may reduce carbohydrate intake for weight loss, it often sidelines antioxidants and plant fiber that regulate hormone function and detoxification.
A review published in Nutrition & Metabolism examined the potential of low-carb ketogenic diets in managing prostate cancer. The authors suggest that while there is biological rationale for benefit, evidence in human subjects remains limited, and the long-term effects on hormone-sensitive organs like the prostate require more data.
“A keto plate full of bacon, butter, and beef without fiber and antioxidants doesn’t support hormone detoxification,” the experts note.
5. Vegan Diet: Plant-Based with Pitfalls
Veganism offers well-documented cardiovascular and environmental benefits—but without careful planning, men may fall short on essential nutrients that support testosterone and reproductive health.
A 2023 review in Nutrients found that zinc and vitamin B12 levels were significantly lower among vegans and vegetarians compared to omnivores. The authors highlighted a consistent trend of micronutrient deficiencies in plant-based diets without supplementation
“Relying too much on soy-based meat alternatives while missing out on B12, iron, and zinc can quietly affect hormonal stability,” Ben’s Natural Health explains.
Expert Takeaway:
“Men don’t need to panic about food but they should stop assuming that ‘fit’ always means healthy,” says a spokesperson at Ben’s Natural Health. “Any diet that ignores micronutrient balance or hormonal needs will eventually backfire. If you’re tracking protein but not minerals, it may be time to rethink your approach.”
