5 days of Fasting-Mimicking

Your Program Journey Step by Step

DAY 1 - ACTIVATION

You have reduced your calories from a regular diet to about 1'100 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.

DAY 2 - KETOGENESIS

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.

DAY 3 - CLEANSE

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.

DAY 4 - REJUVENATION

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.

DAY 5 - ENERGY

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

BURNS ABDOMINAL FAT

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.

IMPROVES METABOLIC HEALTH

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. 

ENHANCES MENTAL CLARITY

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.

STIMULATES CELLULAR REJUVENATION

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.

reSET promotes metabolic flexibility and supports “cellular clean-up.” It is long enough to generate lasting positive effects, yet short enough to avoid overburdening the body. More from Peak Nutrition.

The findings of our study with reSET indicate that FMDs can promote weight loss - largely due to fat burn, alter bioenergetic substrate utilization, and enhance gut microbiome activity. Learn more about the study.

I’ve done this program a few times now and always come away feeling healthy and energized. And by the way, I’ve never felt hungry on it. The food is delicious and filling.
Highly recommended!

Rike

Really nice fasting mimicking Program! The soups were mostly really delicious.
Put the psyllium seeds directly in the soup and added some water, made me feel more full.
I was only eager for protein sometimes, never really hungry. It was fun to prepare each day with soup, snack, electrolytes and morning porridge. Would love to do another one soon.
Noticed just some minor downsides: I am extremely sensitive to stimulants and one snack had cacao nibs what riled me totally up on day 3 also the sleeping pills contain inositol which also make me more alert so I skipped them.
Was also really looking forward to the nougat snacks that were mentioned in the booklet bc it’s my favorite but it was sesame. Which tasted fine though ☺️ 👍🏻

The electrolytes were really great I wish I could get them at Alex or another place in CH.

Laurie Chicha Gaudimier

From far the best fast mimicking diet program I ever followed!! All the products are absolutely delicious, conveniently crafted for easy transportation and I was looking forward to my soups at every meal! Even a week upon finishing the program, I am continuing to eat healthy and am more conscious about my portion sizes! Oh, and my mind is still crystal-clear, an amazing effect that starts at about day 3 of the program!!
Tiny complaint about the plastic containers for the soups, hopefully a more environment-friendly packaging could be thought through, like for the other packaging…thanks for this beautiful discovery!

Rahel

I tried the ReSET Program for the first time, but unfortunately, it didn’t work well for me and I decided to stop after Day 4.

By Day 3, the hunger had become almost unbearable, and I was very close to giving up that evening. By Day 4, I still felt extremely hungry and, more importantly, completely drained of energy. I could barely walk up the stairs, which was very unusual for me. I’m normally extremely fit, work as a personal trainer, and have a background in sports science, so feeling this weak was quite a shock.

Another reason I decided to stop was that I wasn’t seeing any meaningful change in my weight. Since starting the program, I had barely lost any weight, and I even gained 150 g from Day 3 to Day 4.

I understand that everyone responds differently to fasting and nutrition programs, and perhaps this type of fasting-mimicking approach simply isn’t suitable for everyone. However, based on my personal experience, the intense hunger, lack of energy, and lack of noticeable results made it difficult for me to justify continuing.

I’m disappointed that it didn’t work for me, especially given the expectations I had going into the program. I would be interested to hear whether others have had a similar experience or whether the program tends to work very differently depending on the individual.

Dear Rahel,

Thank you for the detailed feedback. I'm sorry to hear reSET left you this depleted. That's not the experience we want anyone to have, and stopping when you did was the right call.

One question, since it may be relevant for you and for other very active customers reading this: were you continuing your normal training load during the program? reSET is a significant calorie reduction, and we specifically recommend against high-intensity training while on it. We provide access to a set of program-specific workouts designed for the reduced calorie intake instead. Maintaining a normal training load on top of the protocol can intensify fatigue and hunger considerably, and work against the results you are aiming for.

We would also encourage anyone experiencing significant hunger or fatigue during the program to reach out to us directl. We're able to adjust guidance in real time rather than have someone push through alone.

Kind regards,
Alex

I won the package at the Health Messe in Basel and I completed the reSET program on Sunday.
At first, I was not sure when I’m able to do the program, because I didn’t want to lose weight. The products are vegan (I have lactose problem) and they don’t expire soon, which is amazing.
After being back from vacation and eating too much on a cruise, I decided to do it, especially as I was lazy to cook and didn’t want to do any groceries.
I was very disciplined, and I loved the products, I lost 2 kg at the end (I think my belly is a little bit leaner). I replaced the chocolate with 40 g of nuts, which was much easier for me and the seeping rate was amazing, thanks to the magical natural sleep tablets.
It was easy to communicate via WhatsApp if I had any questions. I was very happy to eat on day 6 again. It’s actually day 8, eating healthy, but sleep rate slightly lower (in the 70/80 vs 90-96 during the program).
I can totally recommend it even if you’re a fit person and I for sure will do it again.

The EatbyAlex fasting-mimicking program is exceptionally well structured and thoughtfully designed. It provides clear guidance for each day, making it easy to follow throughout the entire process. I particularly enjoyed the breakfast mixes and the small snacks, which were both satisfying and well-balanced.
After completing the program, I felt as though my body had gone through a real reset. I was pleasantly surprised by the increase in my energy levels and also appreciated the extra weight I lost.
I will plan to do it again for sure.
Thank you!

I have followed Eat by Alex since the very early days and tried many different options. The Fast mimicking Program in its actual form (powders, not self made power bars) feels a commodity and too expensive. I will not repeat the experience but make my own soups, broths and shakes again. Best,

I succesfully finished the 5-day ReSet program by EatbyAlex and really loved it. It’s so well organized, and I appreciate that there’s no need to buy anything apart. The soups are delicious, but my favorite part is the in between snacks, it keeps you feeling full. I feel more energized, and my skin looks noticeably more radiant and healthy. Apart from having a strong headache on Day 3 (= regular side effect) I felt pretty good during the week and I even lost 5kg. I can only recommend it and want to integrate the program as a permanet monthly reset into my schedule.

I just finished the 5-day Fasting Mimicking Diet by EatbyAlex and really loved it. It’s so well organized, and I appreciate that there’s no need for freezer storage anymore. The soups are delicious, but my favorite part is the breakfast assortment, it keeps you feeling full, even while fasting. The snacks are great too, and as a bouillon lover, I did two days with just bouillon for lunch and dinner instead of the soups for a bit more challenge. I feel more energized, and my skin looks noticeably more radiant and healthy. For a woman in her late 30s, it’s such an easy, convenient program to integrate as a monthly or twice-yearly reset. I’ll definitely do it again next month.

I did reset and rebuild twice already. The fresh/ frozen food in both programs was really delicious and combined with some freshly chopped herbs even better. One comment about the snacks, they very very close to expiration date or even expired which definitely impacted the taste in one product for me.But I am about to order the next reset. It’s a great program.

Food tastes fresh in the reset program and worked like a charm!
However, some of the dry products (snack bars) had a very close expiration date.

Fasting-mimicking vs juice cleanse (sometimes also referred as a juice fast)

We explain how a juice cleanse compares to fasting-mimicking in this blog post. To summarize, our reSET fasting mimicking program is science-based unlike any of the juice cleanses, it is more convenient, easier to finish, and more nutrient rich due to a high content in fibres.

Fasting-mimicking vs water fast

Water fasting, known for its potential stress on the body, can be challenging to maintain. Research conducted by Dr. Valter Longo revealed that most individuals struggled to complete water fasts due to the difficulty of sustaining such a regimen without any food. Good news - obtaining the same results as water fasting is entirely achievable without putting your body into stress-mode due to prolonged deprivation. That's why we created reSET.

How does fasting-mimicking 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 aging, 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.

What are the macronutrients in reSET?

In reSET, we follow the fasting-mimicking diet approach by Dr. Valter Longo. reSET has the following macronutrient breakdown:


Fats: 50-55% of daily calories

  • The primary source of fats is healthy fats, mainly monounsaturated fats (from olive oil, nuts, and seeds) and polyunsaturated fats
  • Saturated fats, found in foods like dairy, are not found in reSET.
  • Trans fats and highly processed oils are not found in reSET.

Carbohydrates: 35-40% of daily calories

  • Carbohydrates come from whole grains (like whole wheat, farro, quinoa, and brown rice), fruits, vegetables, and legumes.
  • Processed and refined carbs (e.g., white bread, pasta, sugary foods) are not found in reSET.

Proteins: 10-15% of daily calories

  • Protein sources include legumes, nuts, seeds
Is it approved by a nutritionist?

Yes, the reSET program has been reviewed and approved by the team at Peak Nutrition GmbH.

Who is it not for?

If you are:

  • pregnant or breastfeeding
  • underweight (BMI less than 18.5)
  • taking medications
  • feeling weak
  • sick
  • an athlete in training or competition
  • allergic to nuts, seeds, or grains

or if you 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
  • thyroid disorders, particularly Hashimoto's or hypothyroidism

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

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.
