Why not try?
Because it can double the risk of heart disease and stroke (already the leading kiler)
Or increase your LDL levels to those genetically unlucky enough to have familial hypercholesteremia
"Without treatment, the life expectancy of those with familial hypercholesterolemia can be reduced by approximately 15-30 years. However, in people with homozygous familial hypercholesterolemia, the life expectancy may only be 20 years or less"

Or a 30% increased total mortality
"indicates the lowest carb group had 32% higher overall mortality, 50% more cardiovascular disease mortality, 51% higher stroke risk and 36% more cancer"

Or vitamin deficiencies
"Low-carbohydrate diets are often low in thiamin, folate, vitamin A, vitamin E, vitamin B6, calcium, magnesium, iron, and potassium"

Or Alzheimer's Disease increase
Saturated fat intake, which typically increases on a ketogenic diet, is strongly associated with AD risk. In the Chicago Health and Aging Project, high saturated fat intake was linked to a 2- to 3-fold increased risk of incident AD

Or NAFLD increase
In the Rotterdam Study, those consuming the most animal protein were 54% more likely to have NAFLD than those consuming the least (OR 1.54, 95% CI, 1.20–1.98). Dietary components associated with reduced NAFLD risk include whole grains, nuts and seeds, monounsaturated fats, omega-3 fatty acids, vegetable protein, prebiotic fiber, probiotics, resveratrol, coffee, taurine, and choline
Or a lucky dip ...
Longer-term effects of LCD can include decreased bone mineral density, nephrolithiasis, cardiomyopathy, anemia, and neuropathy of the optic nerve
So while some short term benefits might be seen - largely due to removing processed foods - there are many reasons to question this advice for longer term health. And there are ways to see the same benefits but with plenty of research showing improved health outcomes, rather than the opposite. For example the Mediterrean Diet (voted best diet for the 6th year in a row, with the low carb / keto type diets ranked near the bottom)
And none of this is new. It's just a rebranding of previous fads. You can see how previous generations of health influencers fared by watching this 15 min video
