Fasting has become a popular topic in the world of health and nutrition, with a growing body of research suggesting that abstaining from food for certain periods can have significant health benefits. However, fasting may not be suitable for everyone, and some may find it too restrictive. This is where the Fasting Mimicking Diet (FMD) comes in. The FMD is a dietary approach designed to replicate the benefits of intermittent fasting while allowing for some food intake. It is typically followed for five consecutive days once a month for three months and involves consuming a plant-based, low-calorie, and low-protein diet. While the FMD has shown promise in enhancing overall health and well-being, more research is needed to fully understand its long-term effects and efficacy.

What You'll Learn
Who should avoid the Fasting Mimicking Diet (FMD)
The Fasting Mimicking Diet (FMD) is a dietary approach designed to replicate the benefits of intermittent fasting without the total food abstinence associated with traditional fasting. While the FMD may be an appealing way to enhance cellular health and support healthy aging, it is not suitable for everyone.
Individuals who are pregnant or breastfeeding, those with a history of eating disorders, and people with existing medical conditions such as diabetes, kidney disease, or heart disease, should consult with their doctor or dietitian before considering the diet.
Additionally, those on medication should be sure to consult a healthcare professional before starting a fasting diet. Dr. Shelby Yaceczko warns that "individuals who are considered at high risk of malnutrition or undernutrition should typically avoid fasting diet patterns."
The FMD is a structured yet less restrictive form of fasting that allows for a limited amount of food intake. It primarily includes non-starchy vegetables, whole fruits, and healthy fat sources while limiting protein and carbohydrate intake.
While the FMD may be a safe and effective way to experience the health benefits of fasting, it is important to prioritize an individualized approach and proceed with caution.

What foods are allowed on the FMD?
The Fasting Mimicking Diet (FMD) is a dietary approach designed to replicate the benefits of intermittent fasting without the total food abstinence associated with traditional fasting. It is a low-calorie diet that allows for a limited amount of food intake. The FMD is generally considered safe for healthy individuals when followed correctly, but it is not suitable for everyone. It is important to consult a doctor or dietitian before beginning the FMD or any new eating plan.
The FMD is primarily a plant-based diet that includes non-starchy vegetables such as celery, zucchini, tomatoes, and leafy greens. It also includes whole fruits like berries, apples, and oranges. Healthy fat sources such as avocados, walnuts, and olive oil are allowed, providing essential fats while limiting protein and carbohydrate intake. The diet restricts high-glycemic foods such as white rice, white bread, bagels, refined sugars, processed foods, dairy, animal proteins, and starchy vegetables.
The FMD typically lasts for five days and has a specific breakdown of macronutrients (protein, fat, and carbohydrates). On Day 1, individuals consume 1,100 calories, with 11% from protein, 46% from mono- and polyunsaturated fats, and 43% from complex carbohydrates that are rich in fiber. For the remaining four days, calorie intake is reduced to 10%-20% of usual intake.
The Prolon FMD is a prepackaged meal kit that consists of plant-based whole foods and does not include meat, dairy, gluten, GMOs, or processed foods. It also contains a supplemental energy drink made from vegetable glycerine and a plant-based omega-3 supplement from algal oil.

What are the benefits of the FMD?
The Fasting Mimicking Diet (FMD) is a dietary approach designed to replicate the benefits of intermittent fasting without the total food abstinence associated with traditional fasting. It is a plant-based, low-calorie, low-protein, and low-carbohydrate diet, typically followed for five days once a month for three months.
- Weight Loss: The FMD can lead to reductions in body weight and body fat.
- Improved Metabolic Health: The FMD may improve metabolic markers such as blood pressure, fasting glucose levels, and insulin sensitivity.
- Cellular Rejuvenation: The diet may trigger cellular rejuvenation and metabolic changes, which can lead to reduced biological age and disease risk.
- Improved Blood Sugar Management: FMD can help improve blood sugar management, which is beneficial for individuals with diabetes or at risk of developing Type 2 diabetes.
- Decreased Inflammation: FMD has been associated with reduced inflammation in the body, which can have positive effects on overall health.
- Potential Benefits for Alzheimer's Disease: Some studies suggest that FMD can reduce amyloid-beta accumulation, tau phosphorylation, and inflammation, as well as improve cognitive function in animal models of Alzheimer's disease. However, more research is needed to confirm these findings.
- Flexibility and Adherence: Unlike traditional fasting, FMD allows for some food and calorie intake, making it more flexible and potentially easier to adhere to for individuals who find complete food restriction too challenging.
- Overall Health and Well-being: FMD, when done correctly and under supervision, has the potential to enhance overall health and well-being.
It is important to note that the FMD may not be suitable for everyone. Individuals with certain medical conditions, those who are pregnant or breastfeeding, or those with a history of eating disorders should consult with a healthcare professional before considering the FMD.

What are the risks of the FMD?
The Fasting Mimicking Diet (FMD) is a dietary approach intended to replicate the benefits of intermittent fasting without the total food abstinence associated with traditional fasting. While the FMD offers a range of potential health benefits, it is not suitable for everyone. Here are some of the risks associated with the FMD:
Health Risks
The FMD is not appropriate for everyone, and certain individuals should not adopt this diet. These include people who are pregnant or breastfeeding, those with a history of eating disorders, and people with existing medical conditions such as diabetes, kidney disease, or heart disease. Individuals who are at a high risk of malnutrition or undernutrition should also avoid fasting diet patterns. It is crucial to consult with a healthcare provider or a doctor before starting the FMD, especially for those on medication.
Adverse Effects on Medication
There is a risk of adverse effects for individuals taking medications that may be influenced by food, fluid, or specific nutrient intakes. The FMD involves depriving the body of calories, and if the nutrients are not in the right balance, it could slow down the metabolic rate and lead to feelings of starvation, impacting mental health.
Challenges with Long-Term Adherence
The FMD's restrictive nature can pose challenges, and long-term adherence may be difficult for some. The diet's structured yet less restrictive approach may make it appealing, but it still requires discipline and an individualized approach.
Financial Commitment
The ProLon program, for example, can be a financial commitment, and attempting a do-it-yourself approach may not be advisable due to the risk of failing to meet nutrient needs and safely entering ketosis.
Sustainability of Results
The FMD typically lasts for five days, and because of its short duration, the results may not be sustainable. To achieve long-term diet results, a lifestyle change or diet must be followed for several months or years. The FMD may set individuals up for yo-yo dieting and weight loss/regain cycles.

How does the FMD work?
The Fasting Mimicking Diet (FMD) is a dietary approach designed to replicate the benefits of intermittent fasting without the total food abstinence associated with traditional fasting. It is a low-calorie, plant-based diet that allows for a limited amount of food intake, primarily non-starchy vegetables, fruits, healthy fats, and plant-based proteins. The FMD is typically followed for five consecutive days, once a month, for three months.
On the first day of the FMD, individuals consume more calories than the remaining four days. A common recommendation for macronutrient breakdown is to have approximately 34% calories from carbohydrates, 10% from protein, and 56% from fat on the first day, and around 47% carbohydrates, 9% protein, and 44% fat on the remaining four days. The FMD is designed to provide the body with essential nutrients while triggering the beneficial effects of fasting, such as cellular rejuvenation and metabolic changes.
The FMD is not suitable for everyone. Individuals who are pregnant or breastfeeding, have a history of eating disorders, or have existing medical conditions such as diabetes, kidney disease, or heart disease, should consult with their healthcare provider before starting the FMD. It is important to prioritize an individualized approach and maintain proper hydration by consuming at least 70 ounces of water daily.
The FMD has gained attention as a potential tool for enhancing overall health and well-being. It has been studied for its potential benefits in weight loss, improved metabolic health, and as a preventive and curative strategy for Alzheimer's disease. However, more research is needed to fully understand the long-term effects and optimal duration of the FMD.
