The PSMF diet, or Protein-Sparing Modified Fast, is a very low-calorie diet designed to help people lose a lot of weight quickly. The diet involves limiting calories to less than 800-1000 a day, with a high proportion of protein calories and a restriction of carbohydrates and fats. The goal of the diet is to lose fat while maintaining muscle mass.

What You'll Learn
PSMF is a very-low-calorie diet
The PSMF diet is divided into two main phases: the intensive phase and the refeeding phase. During the intensive phase, which can last up to 6 months, calories are restricted to less than 800 kcals a day. The number of calories consumed during this phase depends on the person's lean body mass. For example, a person whose goal weight is 140 pounds (64 kg) would eat 76-95 grams of protein per day.
The PSMF diet is designed to maintain muscle mass while losing fat. "Protein-sparing" refers to the diet's main goal of preventing muscle-wasting effects while still eliminating fats and carbohydrates. Typically, depending on activity level, 0.8-1.2 g of protein per pound of lean body mass is consumed.
The PSMF diet can be dangerous if undertaken without medical supervision. It is important to gradually increase calories after the intensive phase, over 6-8 weeks.

PSMF is a protein-sparing modified fast
The PSMF diet was first introduced in the 1970s to help people with obesity lose weight under the guidance of a physician. The term now refers to many varieties of very low-calorie diets, many undertaken without medical supervision, which can be dangerous.
The diet is divided into two main phases: the intensive phase and the refeeding phase. The intensive phase can last up to 6 months and involves limiting calorie intake to less than 800 calories daily. During this phase, calories mostly come from lean protein foods, like chicken, egg whites, tofu or fish. In a clinically supervised PSMF, patients receive 1.2-1.5 grams of protein per kilogram of their goal body weight per day.
The number one thing that this diet plan does differently than a Ketogenic Diet is that the amount of fats that are consumed is also very low. In the first part of the diet, protein intake rounds up to 1.2-1.5 grams per kilogram of the person’s goal body weight. As far as the carbohydrates are concerned, those who follow a PSMF are only allowed 20-50 grams of them a day.

PSMF involves limiting carbohydrates
PSMF stands for protein-sparing modified fast. It is a very low-calorie diet (under 800-1000 kcal per day) with a high proportion of protein calories and a simultaneous restriction of carbohydrates and fat.
During ketosis, the body breaks down fat into ketone bodies, which can be used as an alternative source of energy. This can lead to rapid weight loss, as the body is burning its own fat stores for energy.
However, it is important to note that PSMF is a highly restrictive diet and can be dangerous if not done correctly. It should only be undertaken with medical supervision.

PSMF involves limiting fats
A Protein-Sparing Modified Fast or PSMF diet is a very-low-calorie diet (under 800-1000 kcal per day) with a high proportion of protein calories and simultaneous restriction of carbohydrates and fats. PSMF diets can last for up to 6 months, followed by a gradual increase in calories over 6-8 weeks. PSMF attempts to spare the dieter the health risks of a complete fast by introducing the minimum amount of protein necessary to prevent muscle-wasting effects, while still eliminating fats and carbohydrates.
The number one thing that this diet plan does differently than a Ketogenic Diet is that the amount of fats that are consumed is also very low. The PSMF diet is all about limiting the amount of carbohydrates a person consumes and at the same time reducing the amount of calories. The diet is divided into two main phases: the intensive phase and the refeeding phase.
The intensive phase can last up to 6 months and involves limiting calorie intake to less than 800 calories daily. In the first part of the diet, protein intake rounds up to 1.2-1.5 grams per kilogram of the person’s goal body weight. As far as the carbohydrates are concerned, those who follow a PSMF are only allowed 20-50 grams of them a day.

PSMF can be dangerous without medical supervision
A protein-sparing modified fast or PSMF diet is a very-low-calorie diet (800 kcal per day) with a high proportion of protein calories and simultaneous restriction of carbohydrate and fat. The PSMF diet is all about limiting the amount of carbohydrates a person consumes and at the same time reducing the amount of calories to less than 1000 kcals a day. The PSMF is a highly restrictive diet that involves severely limiting the intake of calories, carbs, and fat and increasing the consumption of protein.
The PSMF diet is designed to help people lose a lot of weight quickly. The goal is to lose fat while keeping muscle mass. During the intensive phase, a PSMF diet usually includes fewer than 800 calories per day. Calories mostly come from lean protein foods, like chicken, egg whites, tofu or fish.
In a clinically supervised PSMF, patients receive 1.2-1.5 grams of protein per kilogram of their goal body weight per day. For example, a person whose goal weight is 140 pounds (64 kgs) would eat 76-95 grams of protein per day. Without medical supervision, it is difficult to know how much protein to consume and this could lead to health issues.
The PSMF diet can also be dangerous without medical supervision because it restricts carbohydrates and fats. This can lead to nutritional deficiencies and health issues. It is important to have medical supervision to ensure that you are getting the proper nutrients and that your body is handling the diet well.
