The high-protein controversy
Critics of high-protein diets have raised some concerns, however. For one, ketosis is associated with headaches, nausea, kidney trouble and other side effects. Which is why people with kidney disease should consult their doctor before embarking on a high-protein diet.
There are also questions on long-term health impact: Such diets are often high in saturated fat and low in fiber, which can lead to an increase in cholesterol levels and the risk of heart disease and stroke. Plus, high-protein dieters are more likely to miss out on nutrient-rich fruits and vegetables, which have disease- and cancer-fighting properties.
