Let’s stop talking about diets and consider lifestyle changes with good eating programs. A good balance of proteins, fruits, vegetables, and fiber while decreasing (not eliminating) fats and carbohydrates and increasing exercise is a lifestyle change. There are many eating plans that teach you what, how, and when to eat that might make the process helpful. The Ultimate Weight Solution has been very beneficial to me.
Look for a diet that provides you with some flexibility. I have found that high fiber and protein while limiting the fats has worked best for me in the past. Also don't forget to increase your activity as to burn more calories than you take in daily.
A straight protein diet can cause problems, but not usually. The Atkins Diet focuses more on protein and less on carbs, but you don't cut them out entirely. Your body does need some carbohydrates, but you need to get them naturally from fruits, vegetables, and small amounts of whole grains. What you want to eliminate are the simple carbohydrates that give your body an immediate rush and don't stay in your system. You want the complex carbohydrates that take hours to digest, have fiber in them, and give you much more nutrition.
Carbohydrates are the body's main energy source for all types of exercise. Carbohydrate is stored as glycogen in the body, and the amount of glycogen stored in the body affects stamina and endurance. When muscle cells run out of glycogen, fatigue sets in and performance will suffer, though the effects will vary among different sports. Training and eating properly, with particular attention to carbohydrates, can increase and maintain glycogen stores, which is particularly important for endurance athletes.Protein is essential to build and repair muscle tissue. Protein allows muscles to contract, gain in size, and increase in strength. Loading up on protein does not guarantee larger muscles. Protein in excess of the body's needs is stored as fat, not protein. Muscle growth comes from hard work, proper training, and balanced nutrition. Food sources of protein include lean meat and poultry (fish and chicken), fish, legumes (dried beans and peas), nuts, seeds, and dairy products.
