Keto diets have additional important drawbacks. The excessive protein in
low-carb diets has the potential to contribute to kidney and liver damage. High protein diets have been
shown to have detrimental effects on heart disease risk factors, including coronary
artery blood flow. They are also not heart-healthy because, like similar low carb
diets, ketogenic diets likely to be deficient in fiber and micronutrients and are
also likely to have the detrimental effect of increased LDL-cholesterol. They
cannot be considered heart-healthy for long-term use.
The lack of carbohydrates forces the body to mobilize some fat, but even more water and
protein is lost. This results in rapid weight loss, but much of it will be lean-body
protein and water, not fat.
Ketosis can make a person feel unwell with “keto flu” (tired, dizzy, nauseated, weak,
and poor sleep). Keto diets may be dangerous for people with heart disease, diabetes,
or kidney problems. Especially people on medications for diabetes or high
blood pressure should not embark on a ketogenic diet without close medical supervision
because they may suffer dangerously low blood sugar or blood pressure.
