The Prism diet is part of the PRISM Weight Loss Program, which started in 1990. The program combines Christian faith with a healthy lifestyle as a means to overcome food addiction and to maintain healthy weight.
The diet program, which consists of four phases, each consisting of six weeks, advocates eating a low calorie, low carbohydrate diet for nourishment of the body and seeking comfort from daily lessons and inspirational readings contained in a workbook. It allows dieters to eat whole, unprocessed foods amounting to 1,200 to 1,400 calories daily, from a variety of foods that includes fruits and vegetables. Unlike the Atkins diet, which is also a low-carb diet, it does not promote high protein consumption. The program also uses tools such as a daily food journal to help you keep track of your eating habits, instructional videos, workbooks, and meetings with support groups to promote inspiration and success of the program. No food products such as shakes, meal replacements, or diet supplements are sold by the company that promotes the program.
Reviews on the Prism diet mention that some of its advantages include educating people about being mindful eating of food portions when they eat, choosing healthy unprocessed foods, and getting support from a group that is based on faith. However, this may be to the disadvantage of some individuals who do not share their beliefs. Furthermore, the importance of exercise is not emphasized by this diet program.
Can a Low Carb Diet Help You Lose Weight?
There are many types of low-carbohydrate diets that vary according to what types and amounts of foods one can eat. Carbohydrates are macronutrients that come mainly from grains, fruits and vegetables. Some food manufacturers use carbohydrates as a form of added sugar in processed foods, but consumption of these are usually discouraged in low-carb diets.
Carbohydrates are the main source of energy for the body when they are broken down to glucose. These molecules are used by the cells with the help of a hormone called insulin. By consuming a low-carb diet, proponents of this type of diet explain that the body looks for other sources of energy and burns fat, turning it to glucose, resulting in weight loss. Other benefits include lowering your risk for diseases such as diabetes, obesity and heart disease.
A low-carb diet usually limits your intake of carbohydrates to 50-150 grams per day. This is in contrast to the recommendations of the 2010 Dietary Guidelines for Americans, which consist of taking about 225 to 325 grams of carbohydrates a day. Both the American Dietetic Association (ADA) and the American Heart Association (AHA) do not recommend eating low-carbohydrate diets. Limiting the intake of foods that are high in carbohydrates can cause nutritional deficiencies, insufficient fiber intake, and symptoms like dizziness, headache, fatigue, constipation, and weakness. People who have medical conditions such as heart disease, high blood pressure or diabetes should consult their doctors before getting started on low carb diets.
Severely restricting carbohydrate intake can result in rapid weight loss but this weight loss may be difficult to maintain. Many dieters eventually regain the lost pounds, especially without exercise.
