Confirmation bias is “the tendency to search for, interpret, favour, and recall information in a way that
confirms one’s pre-existing beliefs or hypotheses; it is a type of cognitive bias and a systematic error of
inductive reasoning. With the ketogenic diet being all the rage these days, it is important to examine
the fad eating practice from all angles. Yes, it has been shown anecdotally to help people lose weight
fast. Yes, it has been shown clinically to treat epilepsy. Yes, there is emerging evidence from rat studies
that suggest it may have a protective effect on dementia. But there are major reasons to stay away
from the diet that are not talked about often enough. Read through the present list, then research
some more, and then you may come to your own conclusion about whether or not keto is right for you.
1. For individuals under the age of 18, the diet may negatively impact development.
2. For individuals who get ill often, the diet may negatively impact immune system function. Most
immune cells are fuelled by glucose. Taking carbohydrates (i.e. glucose) out of the diet may
increase the risk for illness and infection.
3. For individuals who like to, or need to (i.e. athletes) exercise hard, the diet will absolutely result
in reduced exercise capacity. The ketogenic diet will fuel aerobic activity without problem, but
glucose is needed to fuel more vigorous exercise intensities.
4. For individuals who want to gain muscle, the diet may negatively impact lean tissue gains.
5. For individuals with an eating disorder history, the diet may encourage dysfunctional dietary
6. For individuals with a history of poor discipline or adherence to nutrition plans, the diet may be
difficult to sustain. We must walk before we learn to run. In a similar vein, we must learn how
to eat > 7 servings of vegetables, hydrate adequately, and cut out processed foods and sugars
before learning how to completely eliminate an entire macronutrient (i.e. carbohydrates).
