What Is Fasting Mimicking Diet?

Fast mimicking diet stands apart from conventional prolonged fasting by permitting the consumption of small, calorie-restricted meals.

These meals primarily consist of plant-based components such as olives, vegetables, fruits, nuts, seeds, and herbal teas, amounting to less than half of the average daily food intake in a 2000-calorie diet.

Termed as ‘food fasts,’ this approach is recognized as equally effective as traditional fasting but offers a more sustainable and manageable fasting experience. 

How does the Fasting Mimicking Diet Work?

The 5 day fasting mimicking diet unfolds in a phased approach: 

Day 1: Transitioning into Fasting On the day one of fast mimicking diet, the body begins the shift into a fasting state. Approximately within 8-12 hours, a significant portion of blood glucose is utilized for energy. Overcoming the natural inclination for food, especially in a culture accustomed to three full meals a day, can pose a challenge. 

Day 2: Initiating Ketosis Once glucose reserves are depleted, the body turns to its fat stores for energy, initiating ketogenesis and the production of ketones. By the 48-hour mark, ketosis, characterized by fat burning, commences. 

Day 3: Commencing Autophagy During the initial fasting days, prompting cellular rejuvenation. Autophagy is induced by the mild dietary stress imposed during fasting, a concept known as hormetic stress. 

Day 4: Peak of Autophagy and ‘Fast High’ Autophagy peaks, and individuals may experience a sense of euphoria often referred to as a ‘fast high,’ further diminishing hunger sensations. 

Day 5: Continued Cellular Renewal On the final fasting mimicking diet day, the cellular renewal process persists, yielding enduring benefits, including weight loss and enhanced mental clarity, focus, and energy. After the fast, a marginal increase in body weight might occur, primarily due to the replenishment of lost water weight rather than fat regain. 

Benefits of Fasting Mimicking Diet

The key fast mimicking diet advantages are as follows: 

Weight Loss and Muscle Preservation:  

Fasting mimicking diet approach facilitates weight loss by prompting the body to utilize fat reserves for energy, a process known as ketosis. Importantly, this method preserves muscle mass, as the body predominantly relies on fat stores, minimizing the need to metabolize muscle protein for energy. 

Reduction of Inflammation:  

Long-term adherence to fast mimicking diet, including the fasting mimicking diet, has demonstrated efficacy in reducing inflammation. Chronic inflammation is linked to various health conditions such as Alzheimer’s, cardiovascular disease, and arthritis.

Drawbacks of Fast Mimicking Diet
