Meat, Testosterone, and Libido: Diet vs. Evolution Debate
A 44-year-old man claims that eating lamb, fish, shrimp, pork, and beef for a week—along with some legumes—made him feel energetic while running and significantly increased his libido, which he attributes directly to animal protein. His thesis: if this diet boosts hormones at his age, it can't be bad. This case challenges the dominant narrative and opens two fronts often confused: what we ate tens of thousands of years ago versus how animal fat affects our hormones today.
Are Humans Naturally Carnivores or Vegetarians?
The disagreement starts in prehistory. Some argue that humans became human by eating meat, noting that spears and arrows appear in archaeological sites before plows and grain mills. On the other side, counterarguments insist we remain primates: gorillas don't eat meat, and chimpanzees hunt only exceptionally. The underlying question—what did our ancestors actually eat?—has no definitive answer to settle the dispute.
Vegetarian arguments cite tribes that still live on cereals, roots, and legumes, reminding us that agriculture allowed feeding far more people than hunting could sustain. Conversely, logistical objections arise: a tribe of 50 with access to 30 bison and 50 deer had no refrigerators, true, but meat was also dried and smoked. It is emphasized that high-quality protein was reserved for males.
Does Eating Meat Raise Testosterone?
This is where things heat up. One school argues that low-fat diets—particularly lacking saturated animal fats—hinder testosterone synthesis in men, linking this effect to reduced libido. Another interpretation politicizes the argument: animal rights and environmental movements, they claim, push people away from rural life and reduce population virility.
Optimists assume the hormonal effect is real and attributable to meat; skeptics believe no diet replaces medical treatment and that the surge feels more related to good sleep and training than to the menu. Neither side has presented a single blood test during the exchange. Against the idea that a Western diet rich in carbs and sugars is superior, critics offer an impressionistic comparison—a Vietnamese man of the same age "exhausted, toothless, and wrinkled"—which is an opinion, not data.
Hunting, Livestock, and Lent: What People Actually Ate
The discussion then shifts to documented history. Hunting and gathering lasted tens of thousands of years; organized agriculture emerged between 8,000 and 12,000 years ago, depending on early settlements. But recent history matters too: in much of rural Spain, those with cows, pigs, and chickens secured daily protein—processed meats, eggs, milk—and reserved fresh meat for special days.
Lent serves as both evidence for and against the case. Forty days without eating "meat" didn't miccionan giving up protein: eggs, cheese, cured meats, and salted fish remained on the table. The lingering question is how much meat grandparents actually ate. The answer depends heavily on the village and family budget, a point nobody disputes.
Whey, Creatine, and the Laboratory Shortcut
When natural methods fail to convince, chemistry enters the picture. It is suggested that a scoop of whey or casein protein plus creatine provides more protein per kilo than a steak, and that obtaining just one gram of creatine would require eating kilos of meat. Going further, the conversation turns to selective androgen receptor modulators (SARMs), presented by proponents as less potent than steroids but with fewer side effects. Health warnings remain off the menu.
The conclusion nobody signs: those who feel better eating meat attribute it to meat, while plant-based advocates find equally solid cases for their diet. The 8 billion people on Earth don't eat the same way, nor should they. Which sensation better measures the health of a 44-year-old man: desire or a blood test?
