Ageing is not a disease and therefore, disease-oriented research and treatment approaches are not adequate. It has thus been proposed that the use of health-oriented and preventive strategies is more beneficial than disease-oriented treatments. Calorie restriction (CR) is, to date, the most successful intervention to delay ageing progression or the development of age-related chronic diseases. CR has been defined as the reduction of energy intake without malnutrition. During the last few years it has been demonstrated that CR extends lifespan, extending the healthspan by delaying the onset of age-related diseases in many of the animal models studied. This effect of CR on longevity was explained in a unified theory of ageing as not a simple and passive effect but an active, highly conserved stress response that increases the organism's chance of surviving adversity. Thus, CR produces a response that modifies key process in cell protection, reparation mechanisms and modulation of metabolism that permits a higher survival against adversity. This has been supported by the 'Hormesis hypothesis of CR' that suggests that the induction of a moderate stress causes adaptive responses of cells and organs, preventing further damage due to a stronger stress

A mi contraria no le hace gracia que haga ayunos y demás, pero ahora le estoy echando la excusa de la Cuaresma y hago ayuno los viernes, de cena del jueves a desayuno del sábado...

Me pregunta mosqueada que cómo me he vuelto beato a la vejez... :lol:

jajaja a la mia le gusta ayunar, cuando lo hicimos unos meses por primera vez, estaba como una veinteañera mirandose en el espejo y sacandose fotos del tipo que se le habia quedado... toca retomar!

Voy a hacer la dieta elemental durante tres semanas a la vuelta, va a ser muy duro, pero creo que tengo SIBO, y por lo que he leido eso funciona en un 85% de los casos, ya que es comer en polvo un preparado de Nestle, y nada mas, se absorve en el estomago y nada llega al intestino, habitualmente las bacterias en el intestino delgado se mueren y en la mayoria de los casos no vuelven a reproducirse.

La mayoria de la gente que tiene hinchazon de estomago sobre todo despues de determinadas comidas como azucares, lacteos etc.. y gases, tiene SIBO (Small Intestine Bacterial Overgrowth), nada terrible, pero mejor quitarlo.

A mi determinadas comidas me ponen la tripa como un globo al instante y hablamos de comer solo un poquito, sin embargo con otras no me pasa y coincide con las que causan SIBO, por ejemplo la banana muy verde o la patata fria, es decir cruda o cocinada y dejada enfriar, el azucar tambien suele causar problemas, la lactosa etc...

Interesante,no habia escuchado nunca el termino SIBO. Yo tb tengo hinchazon y molestias de estomago con algunas cosas,sobretodo azucares y lacteos.
¿Y el preparado de Nestle de que esta compuesto?
¿3semanas solo con eso? Supongo que acompañado de complementos vitamínicos, infusiones...no?

Ese preparado ya tiene de todo, de hecho lo recetan los médicos para situaciones en las que hay que dejar descansar al intestino.

Hacia tiempo que no ayunaba y he aprovechado este Ramadan para retomar las buenas costumbres, y ya llevo 4 ayunos...

La verdad es que es increible lo mejor que me puedo sentir cuando ayuno frecuentemente, no hay nada que me haga sentirme tan bien.

Ultimamente me encontraba cansado constantemente y sin energia, yo lo relacionaba con tabajar 12 horas al dia y algunos fines de semana, y me parecia normal.. He empezado a ayunar y he vuelto a estar lleno de energia y activo a pesar de las largas jornadas laborales.

De ahora en adelante me voy a poner una meta que es ayunar como minimo 2 veces al mes y minimo hacer una ronda cada tres meses del ayuno que voy a mencionar a continuacion de 5 dias consecutivos consumiendo entre 30 y 50% de las calorias necesarias, lo dejaremos entre 600 y 800 calorias al dia.

Want to lose abdominal fat, get smarter and live longer? New research led by USC’s Valter Longo shows that periodically adopting a diet that mimics the effects of fasting may yield a wide range of health benefits.

In a new study, Longo and his colleagues show that cycles of a four-day low-calorie diet that mimics fasting (FMD) cut visceral belly fat and elevated the number of progenitor and stem cells in several organs of old mice — including the brain, where it boosted neural regeneration and improved learning and memory.

The mouse tests were part of a three-tiered study on periodic fasting’s effects — testing yeast, mice and humans — to be published by Cell Metabolism on June 18.

Fasting’s lifelong effects
Mice, which have relatively short life spans, provided details about fasting’s lifelong effects. Yeast, which are simpler organisms, allowed Longo to uncover the biological mechanisms that fasting triggers at a cellular level. And a pilot study in humans found evidence that the mouse and yeast studies were, indeed, applicable to humans.

Bimonthly cycles that lasted four days of an FMD which started at middle age extended life span, reduced the incidence of cancer, boosted the immune system, reduced inflammatory diseases, slowed bone mineral density loss and improved the cognitive abilities of older mice tracked in the study. The total monthly calorie intake was the same for the FMD and control diet groups, indicating that the effects were not the result of an overall dietary restriction.

In a pilot human trial, three cycles of a similar diet given to 19 subjects once a month for five days decreased risk factors and biomarkers for aging, diabetes, cardiovascular disease and cancer with no major adverse side effects, according to Longo.

Strict fasting is hard for people to stick to, and it can also be dangerous.
Valter Longo

“Strict fasting is hard for people to stick to, and it can also be dangerous, so we developed a complex diet that triggers the same effects in the body,” said Longo, Edna M. Jones Professor of Biogerontology at the USC Davis School of Gerontology and director of the USC Longevity Institute. Longo has a joint appointment at the USC Dornsife College of Letters, Arts and Sciences. “I’ve personally tried both, and the fasting mimicking diet is a lot easier and also a lot safer.”

The diet slashed the individual’s caloric intake down to 34 to 54 percent of normal, with a specific composition of proteins, carbohydrates, fats and micronutrients. It decreased amounts of the hormone IGF-I, which is required during development to grow, but it is a promoter of aging and has been linked to cancer susceptibility. It also increased the amount of the hormone IGFBP-, and reduced biomarkers/risk factors linked to diabetes and cardiovascular disease, including glucose, trunk fat and C-reactive protein without negatively affecting muscle and bone mass.

Cancer cells starved out
Longo has previously shown how fasting can help starve out cancer cells while protecting immune and other cells from chemotherapy toxicity.

“It’s about reprogramming the body so it enters a slower aging mode, but also rejuvenating it through stem cell-based regeneration,” Longo said. “It’s not a typical diet because it isn’t something you need to stay on.”

For 25 days a month, study participants went back to their regular eating habits — good or bad — once they finished the treatment. They were not asked to change their diet and still saw positive changes.

Longo believes that for most normal people, the FMD can be done every three to six months, depending on the abdominal circumference and health status. For obese subjects or those with elevated disease risk factors, the FMD could be recommended by the physician as often as once every two weeks. His group is testing its effect in a randomized clinical trial, which will be completed soon, with more than 70 subjects.

“If the results remain as positive as the current ones, I believe this FMD will represent the first safe and effective intervention to promote positive changes associated with longevity and health span, which can be recommended by a physician,” Longo said. “We will soon meet with FDA officers to pursue several FDA claims for disease prevention and treatment.”

Cuidado con el Ramadán. Hacer ayuno controlado está bien, pero no te pegues el festín como hacen mis vecinos, que cada anochecer empiezo a oler las barbacoas de cordero y a ver su mesa con pastelitos de miel y así ni dieta ni nada..

Yo no sigo el Ramadan, ni de lejos, yo aprovecho que en Ramadan esta prohibido comer en publico para ayunar, pero por supuesto bebo, y mis ayunos no son cuando hay luz del sol unicamente, son de 40 horas y eso ya de por si te hace el estomago mas pequenio y te dan menos ganas de pegarte el festin.

La semana que viene hare mi primer ciclo de FMD (Fast Mimic Diet) a ver que tal.

Ver: https://www.researchgate.net/publicatio ... Healthspan

Prolonged fasting (PF) promotes stress resistance, but its effects on longevity are poorly understood. We show that alternating PF and nutrient-rich medium extended yeast lifespan independently of established pro-longevity genes. In mice, 4 days of a diet that mimics fasting (FMD), developed to minimize the burden of PF, decreased the size of multiple organs/systems, an effect followed upon re-feeding by an elevated number of progenitor and stem cells and regeneration. Bi-monthly FMD cycles started at middle age extended longevity, lowered visceral fat, reduced cancer incidence and skin lesions, rejuvenated the immune system, and retarded bone mineral density loss. In old mice, FMD cycles promoted hippocampal neurogenesis, lowered IGF-1 levels and PKA activity, elevated NeuroD1, and improved cognitive performance. In a pilot clinical trial, three FMD cycles decreased risk factors/biomarkers for aging, diabetes, cardiovascular disease, and cancer without major adverse effects, providing support for the use of FMDs to promote healthspan.


The human fasting mimicking diet (FMD) program is a plant-based diet
program designed to attain fasting-like effects while providing micronutrient
nourishment (vitamins, minerals, etc.) and minimize the burden of fasting. It
comprises proprietary vegetable-based soups, energy bars, energy drinks,
chip snacks, chamomile flower tea, and a vegetable supplement formula tablet
(Table S4). The human FMD diet consists of a 5 day regimen: day 1 of the diet
supplies 1,090 kcal (10% protein, 56% fat, 34% carbohydrate), days 2–5 are
identical in formulation and provide 725 kcal (9% protein, 44% fat, 47%
carbohydrate)

Sigo investigando la dieta FMD:

- https://thequantifiedbody.net/fast-mimicking-diet/
- http://www.telegraph.co.uk/lifestyle/we ... et....html

La conclusion a la que llego es que a pesar de funcionar intentan sacar pasta con unos productos alimenticios propietarios que no dejan de ser una dieta baja en proteinas y alta en vegetales para evitar IG-1 y mTOR.
