¿El ayuno intermitente ayuda a perder más peso que otras dietas tradicionales?

El ayuno intermitente consiste en alternar períodos en los que se consume muy poca o ninguna energía con otros de alimentación normal.
Es una estrategia que se hizo popular en redes sociales por la promesa de que permite bajar el sobrepeso de manera rápida.
Sin embargo, una revisión de estudios de la organización Cochrane, que está formada por 11.000 miembros, puso en duda ese entusiasmo.
“El ayuno intermitente simplemente no parece funcionar para adultos con sobrepeso u obesidad que intentan perder peso”, afirmó Luis Garegnani, autor principal de la investigación y director del Centro Cochrane Asociado del Instituto Universitario Hospital Italiano de Buenos Aires, en Argentina.

El equipo de investigadores analizó los resultados de 22 ensayos clínicos aleatorizados en los que participaron 1.995 adultos de Norteamérica, Europa, China, Australia y Sudamérica.
En esos estudios, se probaron diferentes modalidades de ayuno, como dejar de comer en días alternos o restringir las comidas a ciertas horas del día.
La mayoría de los ensayos realizó un seguimiento de los participantes durante hasta 12 meses.

El hallazgo central fue claro: el ayuno intermitente no mostró un efecto clínicamente significativo sobre la pérdida de peso en comparación con los consejos alimentarios habituales o con no hacer nada.
Esta conclusión desafía la creencia popular reforzada por el contenido viral en plataformas digitales.

La revisión también examinó los límites y alcances de la evidencia. Los efectos secundarios observados no permitieron a los autores extraer conclusiones definitivas.
“La evidencia científica sigue siendo limitada, con solo 22 ensayos, muchos con muestras pequeñas e informes inconsistentes”, detalló Garegnani.
Otro factor importante es el perfil de los participantes: la mayoría eran personas blancas de países de ingresos altos, por lo que no se sabe si los resultados serían iguales en otros grupos.
“La obesidad es una enfermedad crónica. Los ensayos a corto plazo dificultan guiar la toma de decisiones a largo plazo para médicos y pacientes”, remarcó Garegnani.
La revisión destacó que pocos estudios han considerado los efectos a largo plazo, lo que restringe la posibilidad de hacer recomendaciones universales.
Frente a la popularidad del ayuno intermitente en internet, Garegnani alertó sobre la diferencia entre la percepción pública y la evidencia científica.

“El ayuno intermitente podría ser una opción razonable para algunas personas, pero la evidencia actual no justifica el entusiasmo que vemos en las redes sociales”.
Por eso, los investigadores aconsejaron no generalizar los resultados. “Estos resultados podrían dar pistas, pero no se pueden extrapolar a toda la población, ya que podrían variar según el sexo, la edad, el origen étnico, el estado de la enfermedad o los trastornos o conductas alimentarios subyacentes”, indicó Garegnani.
La cautela ante recomendaciones generales es compartida por Eva Madrid, investigadora de la Unidad de Síntesis de Evidencia Cochrane de Iberoamérica.
“Con la evidencia actual disponible, es difícil hacer una recomendación general. Los médicos deberán adoptar un enfoque individualizado para cada caso a la hora de asesorar a adultos con sobrepeso para adelgazar”, señaló Madrid.

Desde España, Ana Belén Crujeiras, miembro de la Sociedad Española de Obesidad y jefa de Epigenómica en el grupo de Endocrinología y Nutrición del Instituto de Investigación en Salud de Santiago (IDIS), opinó: “Es una revisión rigurosa que cumple con los estándares científicos para las revisiones sistemáticas. Sugiere que el ayuno intermitente no adelgaza más que las dietas tradicionales”.
No obstante, “la calidad de muchos estudios es limitada y el seguimiento, breve, por lo que no puede considerarse la última palabra”, sostuvo Crujeiras al ser consultado por SMC España.
Además, añadió: “El ayuno intermitente puede ser útil en muchos casos; existen evidencias científicas que lo respaldan. Si se realiza correctamente, genera una situación de cetosis nutricional, que puede aportar beneficios para la salud, ya que los cuerpos cetónicos presentan propiedades antioxidantes y antiinflamatorias, además de actuar como moléculas señalizadoras capaces de modular mecanismos epigenéticos”.

Se ha observado que “este estado de cetosis nutricional se relaciona con mejor bienestar y calidad de vida”, afirmó.
La obesidad es una enfermedad crónica que requiere un abordaje integral y personalizado.
Los tratamientos deben adaptarse a cada persona, porque ciertas estrategias funcionan en unos individuos y otras, en diferentes casos, según el estilo de vida, las preferencias y el perfil fisiológico.
La supervisión de un profesional en nutrición o endocrinología resulta imprescindible para encontrar la mejor opción.

Nepal probe exposes $20M fraudulent rescue scheme involving lacing Mt Everest hikers’ food: report

NEWYou can now listen to Fox News articles!
An investigation has exposed a nearly $20 million insurance scam in Nepal involving guides who allegedly fake or induce mountainside rescues, including by lacing the food of some hikers near Mt. Everest, according to a report by The Kathmandu Post.
Kathmandu is the capital of Nepal, where some adventurous individuals go to climb Mount Everest, the world’s highest peak.
The mountain sits on the border of Nepal and the Tibet Autonomous Region of China.

The Kathmandu Post reported that after it highlighted the fraud in 2018, the government established a fact-finding committee, issued a 700-page report and declared reforms.
But last year, the Nepal Police’s Central Investigation Bureau (CIB) reopened the matter and discovered that the fraud was increasing.

The outlet indicated that the CIB probe points out two main fraudulent scenarios.
One involves guides suggesting to tired adventurers who do not want to walk back that if they feign illness, a chopper will pick them up, according to The Kathmandu Post.
The outlet reported that, in the other scenario, guides and hotel staff, according to the CIB probe, have been coached to scare trekkers at high altitude, where altitude sickness can occur. They allegedly claim that the trekkers are in danger of dying and that only immediate evacuation will spare them.
In some instances, investigators discovered that Diamox (acetazolamide) tablets, utilized to prevent altitude sickness, were given in conjunction with excessive water intake to cause the symptoms that would give grounds for a rescue, the outlet reported.
In at least one instance noted in the investigation, guides allegedly laced food with baking powder to cause people to be unwell, the outlet stated.

Police recorded a case in which four individuals were picked up on one chopper flight, but insurance claims were filed as more than one separate rescue, the report noted.
The framework tying the system of mass fraud together was detailed in police interrogations, according to the outlet, which reported that hospitals shell out 20% to 25% of the insurance money to trekking businesses and 20% to 25% to chopper rescue operators in return for patient referrals.
Trekking guides and their businesses get a boost from inflated invoices, the outlet suggested. In some instances, tourists are offered money to join in the scam, The Kathmandu Post added.
In the period between 2022 and 2025, investigators found a whopping 4,782 foreign patients serviced at implicated hospitals, with 171 cases verified as fraudulent rescues, the outlet reported. During that span, Era International Hospital raked in deposits of over $15.87 million for such activities and Shreedhi International Hospital got more than $1.22 million, the outlet reported.
Mountain Rescue Service carried out 171 fake rescues from an overall 1,248 charter flights, scoring around $10.31 million from insurers, the outlet reported, adding that Nepal Charter Service executed 75 fake rescues out of 471 flights, claiming $8.2 million. Everest Experience and Assistance was allegedly tied to 71 suspicious rescues out of 601 flights, with claims of $11.04 million.

CIB charged 32 people last month with offenses against the state and organized crime, the outlet reported, noting that nine individuals were arrested while others were said to be absconding.
Individuals from Mountain Helicopters, Altitude Air and Manang Air, which was rebranded as Basecamp Helicopters, as well as physicians and administrators with Swacon International Hospital, Shreedhi International Hospital and Era International Hospital were among the individuals who have been charged, the outlet indicated.

Trump administration accused of violating court order by sharing Medicaid data with ICE

NEWYou can now listen to Fox News articles!
More than a dozen Democratic-led states are accusing the Trump administration of violating a federal court order by sharing Medicaid data with Immigration and Customs Enforcement, asking a judge to enforce the ruling.
The states’ complaint asks the U.S. District Court for the Northern District of California to enforce its existing injunction blocking HHS from sharing Medicaid data with ICE.
«The Trump Administration appears to be defying a direct court order blocking it from sharing the personal, sensitive data of individuals including U.S. citizens and lawful permanent residents. It’s invasive — and deeply troubling,» said California Attorney General Bonta, who led the coalition of 22 states. «When Californians signed up for Medi-Cal, they did so with the understanding that their data would not be used for purposes unrelated to administering this program. I urge the court to enforce its earlier order and make clear that these guardrails exist for anyone who is lawfully residing in the United States.»
The complaint stems from a lawsuit spearheaded by California in July 2025 against the Trump administration. The lawsuit accused Health and Human Services of violating federal law through its «mass transfer of sensitive Medicaid data» of both lawful permanent and temporary residents. The lawsuit also argued that the sharing of the personal information will likely create a «chilling effect on individuals’ willingness to enroll in Medicaid programs» for which they are legally eligible.
SECOND FEDERAL JUDGE BLOCKS IRS FROM SHARING ADDRESSES WITH ICE

A federal judge ruled last December that the Trump administration is not allowed to collect the personal information of lawful permanent residents or citizens, but that it can continue to collect basic information from individuals such as addresses, birthdates and immigration status for residents with temporary status. However, the scope of data that can be collected is limited and cannot include sensitive health information.
The attorneys general accuse Health and Human Services of sharing «a large and complex» set of data on Medicaid recipients with ICE, which is in violation of a federal court ruling allowing the exchange of limited personal information but excluding the information of legal permanent residents. The complaint also accuses the Trump administration of failing to share its criteria for determining if a resident is being «lawfully present.»
CATO Institute Senior Legal Fellow Dan Greenberg told Fox News Digital there is «a strong possibility» that HHS and ICE violated the district court’s order.

«The reason this is a strong possibility is that DHHS communications apparently indicate that it shared a ‘large and complex’ dataset of Medicaid recipients with ICE,» Greenberg said. «That phrase suggests that the dataset that was shared with ICE may have included information that is outside the scope of the court order. That is a question of fact: that is why the states are now asking the court to compel the federal government to explain just what was shared and how it is now being used.»
Greenberg also pointed out that the Transformed Medicaid Statistical Information System database does not «appear to have any simple or direct way to identify/single out immigrants who are undocumented,» making «information-sharing that complies with that court order difficult or impossible.»
«The TMSIS identifies people who are only eligible for emergency Medicaid services, but the problem is that this class of people includes both undocumented and lawfully present immigrants,» Greenberg said. «In short, it is as if the court order said that only some of the information in one particular file should be disclosed, but there is reason to believe that DHHS decided that — because they can’t figure out how to separate out this particular type of information – they may have handed over the whole filing cabinet.»

In addition to California, attorneys general of Arizona, Colorado, Connecticut, Delaware, Hawaii, Illinois, Massachusetts, Maine, Maryland, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, Rhode Island, Vermont, Washington, Wisconsin, and the governor of Kentucky signed on to the complaint.
