Many people start vegetarian and vegan diets without devoting an adequate amount of time to nutritional research and meal planning. As a result, considerable amounts of people who start vegetarian diets do not last for more than 1-2 months.
Many dieters who fail to carefully research and plan complain that they lack energy – and often experience a significant loss in muscle mass. Others observe a number of other more peripheral problems that come with a poorly planned vegetarian diet.
The first group–the groups that most failed dieters fall into–is actually experiencing a form of protein-energy malnutrition (PEM). PEM emerges when a person fails to consume enough protein, leading to muscle loss – and subsequently feelings of weakness that are often accompanied by head and muscle aches.
