Caution: High protein diets may pose problems

In our society today, weight and appearance seems to be the main focus on people's minds. After all, who doesn't want six pack abs or great arms? So, in order to reach this ideal perfect body, people will often turn to quick fixes also known as fad diets.

Fad diets often sound too good to be true and in reality, probably are. The Academy of Nutrition and Dietetics recommends steering clear of any diet plans that make the claims such as rapid weight loss, no need to exercise, rigid menus, food group restrictions or specific food combinations.

Of all of the fad diets, high protein diets, which are low in carbohydrates and fats are the most dangerous. These diets generally recommend dieters receive 30 percent to 50 percent of their total calories from protein. They also limit intake from other food groups, such as dairy and fruits and vegetables.

When carbohydrates are drastically restricted, the body goes into a different metabolic state called ketosis, whereby it burns its own fat for fuel. Under normal circumstances, the body burns carbohydrates for fuel - this is the main source of fuel for the brain, heart, and many other organs. A person getting their energy from the breakdown of fat stores is in ketosis. When the body is in ketosis, you tend to feel less hungry, and thus you're likely to eat less than you might otherwise. Because you are less hungry and you are burning fat stores, you can actually lose weight, however the weight loss is only temporary, plus there are other dangers.

Ketosis can cause headaches, irritability, nausea, kidney trouble and heart palpitations. A low carbohydrate intake can increase blood uric concentrations, which can lead to kidney stones. Also, this diet lacks certain vitamins and minerals that have to be supplemented because certain food groups are cut out. Avoiding fruits and vegetables means avoiding important antioxidants and fiber. Lastly, high protein diets are linked to elevating cholesterol, due to heavy reliance on meats, which means high risk for heart disease and other conditions.
