"My doctor told me to eat meat."
medical advice deserves to be taken seriously and understood. If it's general rather than tied to your case, it carries less weight than institutional positions. The US Academy of Nutrition and Dietetics and the British Dietetic Association recognize that well-planned plant-based diets are adequate. Many doctors receive little training in nutrition. There may be specific clinical reasons for the advice, and they should be understood, but "eat meat" is rarely the only solution.
Short answer
It's worth understanding why. If there's a clinical reason, such as an iron or B12 deficiency, it almost always has a solution without meat, with supplements and adjustments. If the recommendation is general, it runs against the main nutrition bodies, which consider well-planned vegan diets adequate. Many doctors receive little training in nutrition. A second opinion, from a dietitian who knows plant-based diets, can help.
For children
Doctors and dietitians know a lot and help us stay well. But sometimes they each think differently. That's why it's good to ask: "Why do I need this? Is there another way?" Many dietitians know how to plan meals with only plants that keep us strong and healthy.
"Did your doctor explain which nutrient in meat you need, and whether it can come from another source?"

"My doctor told me to eat meat."
"My dietitian said I need it."
"No doctor recommends veganism."
"Real doctors know meat is essential."
"Individual clinical advice takes precedence over general recommendations."
"Children and pregnant women can't be vegan." (which is G8)
The strongest version
"My dietitian said I need it. No doctor recommends veganism."
Strongest version (steelman):
- P1My doctor or dietitian knows my health and has examined me.
- P2They recommended that I eat meat.
- P3It's prudent to follow the advice of health professionals.
- CSo I should eat meat.
P1, P2 and P3 may be true. The problem is that the recommendation may have reasons that allow alternatives, or may reflect a personal opinion contrary to the positions of the professional bodies in the field.
The argument is valid. Its soundness depends on the case: it fails when the advice runs against the evidence without a specific clinical reason.

Reconstruction and diagnosis
The recommendation may have different bases:
Basis of the recommendation What to do A specific deficiency (B12, iron) Correct it with supplements and adjustments, with no need for meat A rare clinical condition that greatly limits possible foods Follow the advice, with possible adaptations The professional's general opinion about meat Compare with institutional positions; seek a second opinion - b
Where the argument breaks
1. Following your doctor is reasonable, but it's worth asking why.
Trusting the person who follows your case isn't a fallacy. The error lies in turning individual advice, or a professional's general opinion, into a rule for everyone: in that case, it weighs less than the positions of the bodies that gather the evidence in the field.
2. Nutrition bodies consider the diet adequate.
The US Academy of Nutrition and Dietetics and the British Dietetic Association recognize that well-planned plant diets can support healthy living at all ages.
3. Medical training in nutrition is limited.
In the United States, a 2010 survey found an average of about 20 hours of nutrition across the whole of medical school, and only a quarter of schools met the recommended minimum of 25 hours. Dietitians are the professionals best placed to plan a diet.
4. Almost every clinical reason has an alternative.
Deficiencies of iron, B12 or protein can be corrected without meat.
5. "No doctor recommends it" is false.
Many doctors and dietitians recommend plant-based diets, and medical and nutrition bodies recognize them.

The strongest counter-reply: the professional knows my case
The most serious version says the professional who follows the person knows details that general recommendations don't consider, and that it would be unwise to ignore them.

Why the counter-reply doesn't reach the conclusion
Knowing the case matters, which is why it's worth asking the reason.
If there's a specific reason, it may have another solution.
A second opinion is common practice in medicine.
It isn't disrespect; it's care.
If there really is a need, it's an exception.
Veganism already allows for what is "possible and practicable" (D3).

Back to the moral question
If the recommendation has a real clinical reason with no alternative, it's an exception, not a rule. For most people, the positions of nutrition bodies show that meat isn't necessary, and the moral question returns to the center.
Reasoning errors
Logical
Is the form valid?
Appeal to authority
Unwarranted generalization
Epistemological
Does the evidence support it?
Ignoring institutional positions
Biases
Authority bias
A professional's word settles the question
General literature on heuristics
Confirmation bias
Advice that confirms the habit is accepted without questions
General literature on confirmation bias
Extrapolations
The principle being tested is: "if a professional recommended it, it's right".
If it applied to…Doctors who recommended cigarettesTap to see
They'd be authority enough
This happened in the past
If it applied to…Professionals with differing opinionsTap to see
All advice would be equally valid
Consensus is what makes the difference
If it applied to…Doctors who recommend a plant dietTap to see
They'd be authorities too
The argument cancels itself out
Contradictions
Especially for important diagnoses.
Many people ignore recommendations about exercise or alcohol.
But not on this one.
What the argument gets right
What is true
Following the advice of health professionals is generally prudent, and there are clinical cases where dietary restrictions make sense. No one should ignore a doctor or dietitian who looks after their health.
But
But it's possible to respect the professional and understand the reason for the advice. Almost always, what the body needs is a nutrient, not an animal, and there are professionals ready to help get it another way.
