PSMF Diet Program
Obesity is a primary health concern and a risk factor for coronary heart disease, diabetes, gall bladder disease, arthritis, and peripheral vascular disease. Weight loss can make a significant contribution to improving general health and well-being. The Protein-Sparing Modified Fast (PSMF) is designed for rapid weight loss and incorporates medical, nutritional, and behavioral components.
While on the PSMF program, only lean meat, seafood, poultry, and a limited amount of low-carbohydrate vegetables should be eaten. Carbohydrates and additional forms of fat are not allowed on this program. The high protein intake is to prevent the body from using its own protein stores in muscles, tissues, and cells for energy. Thus the program is a "modified" fast.
Carbohydrates are usually the body's primary source of energy. Since a very limited amount of carbohydrates are consumed, fat becomes the primary fuel source for the body. This rapid breakdown of fat produces ketones that spill into the urine, called ketosis. Ketones in the urine are desirable. While in ketosis, most people lose their appetite, which is a benefit of this program. A large amount of the water in your body is stored with carbohydrates. Since carbohydrate intake is severely limited and storage is severely depleted, dehydration is a health concern. To compensate, adequate quantities of fluid, sodium, and prescription potassium are required each day. Eating foods that are not appropriate can stop ketosis, which not only means less weight reduction, but it can cause dangerous shifts in the body's fluid and electrolytes.
Behavior modification
You will be asked to change your eating habits. Throughout the program, new behaviors will be introduced to encourage healthy habits. Your serious effort is required to change old eating habits, which will help you reach and maintain your desired weight. Your physician or dietitian may recommend an appointment with a psychologist to assist with behavior modification.
Refeeding
When your goal weight is achieved, protein and dietary supplement intake will gradually be reduced while carbohydrates are reintroduced. This "refeeding phase" is essential for long-term success. Principles of a well-balanced diet are implemented to design a long-term weight control program. You will see the dietitian every two weeks during the beginning of refeeding.
PSMF success
As with any diet, success results when an individual is willing to make lifestyle changes. Patients who have completed the PSMF have been successful with weight loss. They’ve successfully maintained weight loss with the refeeding process and implementation of behavior changes.
Atkins
Atkins is a low-carbohydrate diet. The Atkins diet involves limited consumption of carbohydrates to switch the body's metabolism from metabolizing glucose as energy over to converting stored body fat to energy. This process, called ketosis, begins when insulin levels are low; in normal humans, insulin is lowest when blood glucose levels are low (mostly before eating). Reduced insulin levels induce lipolysis which consumes fat to produce ketone bodies. On the other hand, caloric carbohydrates (for example, glucose or starch, the latter made of chains of glucose) affect the body by increasing blood sugar after consumption. (In the treatment of diabetes, blood sugar levels are used Carbohydrate Counting.) Fiber, because of its low digestibility, provides little or no food energy and does not significantly affect glucose and insulin levels.
The Atkins Diet restricts "net carbs" (digestible carbohydrate grams that affect blood sugar less fiber grams). As at first stage which is “Induction Stage” only 20grams carbs is allowed.
In conclusion, these both diet plans might have similarity by adopting protein diet in their menu and promotes ketosis process while dieting. Nevertheless PSMF more concerns on high protein diet where protein intake of c.1.2-1.5 grams per kilogram of body weight whereas Atkins more concerns on low-carbohydrate diet which they emphasize on carbs intake eg in induction stage only 20 grams of carbs is allowed.
Since carbohydrate, protein, and fat are the nutrients in food that provide energy for proper functioning, maintenance, and repair of the body, therefore these three nutrients requires water, vitamins, and minerals as provided in Alpha Lipid SDII formula.
