One of the most important things for women to understand with weight loss or becoming/staying fit is that diet together with exercise is essential in achieving successful results. Depending on your individual nutritional needs and your specific exercise routine, you must choose a diet plan that you can incorporate in your daily routine and as part of a permanent lifestyle change.

There are several diet plans available, but you must take into consideration various factors before choosing the right one for you. First, nutritional energy comes from three sources: carbohydrates (sugar), protein, and fat. Carbohydrates and protein are lower in energy value compared to fats, but carbohydrates are the first source to be used on a daily basis. However, too much carbohydrates end up storing in your body as fat. Eating too much protein can deprive your body of the essential carbohydrates and fats that your body needs to function properly.

Another factor to consider is the type of exercises you choose to do. It is recommended that when performing cardiovascular exercises that you consume more carbohydrates because that is the first source of energy to be used up. Eating more protein is recommended when performing strength training exercises to help build muscle. 

What does all this mean? Well, you need to have a diet plan that incorporates all three sources of energy. It is up to you to decide how much more of one type you should eat depending on the types of exercises you choose to perform. You will also need to know the difference between good and bad carbohydrates and fats (see article: Fat and Carbs). A diet plan should be specially thought out for each individual to focus on their nutritional needs as well as taking into consideration any allergies or tolerance issues one may have.

A proper diet will allow you to exercise better and facilitate desired goals, and regular exercise will help you keep eating a nutritional diet.  

Note:  Diet pills are not the best method for weight loss because most of them are not effective.  However, the ones that do show results often cause drastic weight loss in a short amount of time which is extremely dangerous for the body.  Also, weight loss obtained in this manner often causes the individual to gain the weight back twice as quickly.  For the most part, diet pills do not do as they claim.
