This objection from a dietitian (Dietitians Weigh in on the Low Carb/Ketogenic Diet) is funny since it’s true on one sense but not what the dietitian intends:
Ketogenic diet emphasizes on one macronutrient (Fat) while ignoring the importance of others (carb, protein and natural sources of vitamin & minerals). Thus, leading towards nutritional deficiencies if followed long term.
I’ve already tackled the protein question earlier in this series (Objections to the Keto Diet – Part 7 – Keto is Low Protein).
No one has ever demonstrated that a lack of carbohydrates leads to nutritional deficiencies in the long term. I did look at the long term studies which show no such deficiencies (Objections to the Keto Diet – Part 4 – Long Term Consequences Are Unknown).
But this charge is more serious. It’s not that the consequences are unknown but they that keto will lead to deficiencies. I’ve not seen any studies showing that and I suspect that there is no basis for this charge other than bald faced assertion.
Produce the evidence or retract the charge. Show me what I am missing in my typical keto micronutrients. I publish them here – my last seven days averages. Show me yours, Dietitian. I bet I do better on keto than you do on your diet.
I do put salt in my coffee and don’t log it so my sodium is fine (just in case they care).
Want to see my other macros? OK. Here’s my last 7 day’s averages. What’s missing, dietitians? 30g net of veggies. 222g of fat. 161g of protein. They will probably tell me I am eating too much protein.
