5 days of Fasting-Mimicking

Your Program Journey Step by Step


You have reduced your calories from a regular diet to about 1100 kcal. Your body may now start entering into fasting mode. This is also when you may start the process of cellular clean-up, called autophagy. For some, fat burning starts right away.


As you further restrict your daily calories to 800 kcal, your body may start to produce ketones. By the end of the day, ketosis may start. Ketosis is a metabolic state in which the body uses fat, rather than glucose (sugar), as its primary source of energy.


Research shows that when the food intake is reduced, such as today with 800 kcal again, the energy levels of cells drop. This stress signals cells to initiate autophagy as a way to recycle existing components and maintain cellular function. Fat burning and ketosis may also increase today.


Today you will eat 800 kcal again. Autophagy should reach its peak, and you may feel a boost of energy and positive mood. Fat-burning might continue, and feelings of hunger might also be further reduced.


Today is your last day on 800 calories and your body is freshly energised and reset. Cellular renewal may continue beyond day 5, with lasting results of fat burning, increased mental clarity, and energy.

The science of fasting-mimicking

View full research


Like other restricted calorie diets, the Fasting-Mimicking Diet can help in weight loss and abdominal fat burning by reducing calorie intake and promoting the body’s fat-burning mechanisms.

Burns abdominal fat

The Fasting-Mimicking Diet, like other calorie-restricted diets, offers a potent tool for weight loss by strategically curbing calorie consumption and promoting the body's fat-burning mechanisms. This high fat, low carbohydrate dietary approach involves periods of reduced calorie intake designed to mimic the effects of fasting, leading to a calorie deficit. By consuming fewer calories than the body needs, the body is prompted to turn to fat stores for energy, effectively promoting weight loss. Studies have shown that three cycles of Fasting-Mimicking diets significantly reduced body weight and body fat.


Fasting-Mimicking Diets can induce metabolic switching, whereby the body undergoes a transition in fuel utilisation from glucose to ketones. This process is believed to contribute to the improvements in metabolic markers such as blood sugar levels, cholesterol and triglycerides. 

Improves metabolic health

Fasting-Mimicking Diets have been shown to improve various metabolic markers which are closely linked with aging, diabetes, cancer, and cardiovascular disease. Dr. Valter Longo’s landmark study of the Fasting-Mimicking Diet showed participants experienced lower blood pressure, decreased insulin-like growth factor (IGF-1), and lower cholesterol and triglycerides. Research indicates that Fasting-Mimicking Diets can induce metabolic switching, the process by which the body undergoes a transition in fuel utilisation from glucose to ketones. This process is believed to contribute to the improvements in metabolic markers. 


Fasting and Fasting-Mimicking Diets can increase levels of brain-derived neurotrophic factor, a protein that supports brain Function and reduces the risk of neurodegenerative diseases.

Enhances mental clarity

The Fasting-Mimicking Diet can promote brain health by increasing levels of brain derived neurotrophic factor (BDNF). BDNF is a crucial protein that supports brain function and reduces the risk of neurodegenerative diseases. BDNF promotes the growth, development, and survival of neurons in the brain. High levels of BDNF are associated with good cognitive performance including learning and memory. Decreased BDNF expression is seen in many neurological diseases including Alzheimer’s, Parkinson’s and Huntington’s. BDF is a critical protein that supports brain function and has a broad influence on various aspects of brain health and well-being.


Fasting stimulates autophagy, a process whereby cells clean out damaged components. The Fasting-Mimicking Diet has been shown to promote the regeneration of stem cells, especially in the immune system.

Stimulates cellular rejuvenation

Fasting triggers a cellular process called autophagy, a process whereby cells eliminate damaged components. Autophagy can help to maintain cellular health and function.  A Fasting Mimicking Diet, which is designed to replicate the effects of fasting, has been shown to promote the regeneration of new stem cells, particularly within the immune system. Fostering the regeneration of immune stem cells can potentially boost the body’s immune function and enhance its ability to repair and rejuvenate tissues.

How does reSET work?

reSET is a 5-day program inspired by the fasting-mimicking diet created by Dr. Valter Longo. He has dedicated years of research to achieving longevity, slow ageing, reducing disease and weight management through plant-based and whole food nutrition. You can read more about it in his book “The Longevity Diet” which we highly recommend. Eat by Alex created this program using the concept of fasting-mimicking which puts your body into a fasting mode while still providing the right nutrients and supplements to your body. The restricted calorie diet makes your body think you are fasting and therefore reset and cleanse.The package includes all your meals as well as supplements for 5 days. All the meals will be delivered once for the whole week. Delivery on Friday, you can start your program on Saturday, Sunday, or Monday. You can order it here.

How often can you do reSET?

No more than one week every month if you are healthy with a normal weight and if you are regularly exercising.

Who can take part in reSET?

People who are:

  • Aged between 18 and 60 years old
  • Healthy
  • Healthy weight
  • Feeling strong in their body
  • Not sick – even a mild flu
  • Not taking any medication

Consult and seek approval from your doctor or nutritionist before signing up for reSET.

Who cannot take part in reSET?

People who are:

  • Pregnant or breastfeeding
  • Underweight (BMI less than 18.5)
  • Taking medications
  • Feeling weak
  • Sick
  • Athletes in training or competition
  • Allergic to nuts, seeds, or grains

People who have:

  • Diabetes, cancer, cardiovascular, autoimmune or neurodegenerative disease - please consult your physician for advice, permission and approval
  • Liver or kidney disease
  • Low blood pressure or high blood pressure
  • History of eating disorders
Are there any possible side effects to reSET?

Many people experience few, if any, symptoms during the reSET program. However, some symptoms are indicative of toxins leaving your body. In fact, the more toxins there are to be eliminated, the more symptoms you can experience. These feelings typically pass within the first 3 days.

You may feel weak, flu like symptoms, nausea, dry mouth, constipation or diarrhea, bloating and/or gas, feeling cold, feeling hungry, and irritability. Headaches, ranging from mild to strong migraines, are also very common during the first 2 to 3 days especially when you eliminate caffeinated drinks and refined sugars. Headaches can be relieved by drinking additional water or one black coffee.

Clinical studies have identified potential risks and discomfort associated with low calorie and low protein diets such as reSET, including anxiety, depression, dizziness, drowsiness, fatigue, headache, hunger, irritability, muscle aches, nausea or spinal pain. You may also feel kidney and liver pain as your body works very hard to detoxify.

The hungry feeling comes from the hunger hormone called Ghrelin which spikes around mealtimes. The reSET program will help you stabilise Ghrelin, and we recommend you leave at least 12 hours between your last meal and the next day’s first meal.
