IS IT SAFE?
There is still no agreement on this. Although high-protein diets can help you lose weight, some experts are worried that too many fatty meats and dairy foods that are high in saturated fat and low in fibre may raise your cholesterol and risk of heart disease and stroke. In addition, eating fewer vegetables and grains may reduce fibre intake and other important nutrients.
A more moderate diet, which cuts fat but doesn't cut too many carbs, together with adequate grains and fibre may work safely and is strongly recommended. Therefore, while these diets can work, you need to carefully consider the risks and rewards.
