As anyone seeking to lose weight knows, diets come in and out of fashion. The Sexy Pineapple diet, launched by a Danish psychologist in 1970, never really took off. Kellogg’s no longer promotes the Special K diet, which swaps out two meals a day for a bowl of the breakfast cereal of that name. These days, you don’t hear much about eating according to blood type, cutting out acidic foods, or following the potato diet.

Intermittent fasting has, however, had unusual staying power for more than a decade—and has grown even more popular in the past few years. One survey found that almost one in eight adults in the United States had tried it in 2023.

The enduring popularity of intermittent fasting has been fed by celebrity endorsements, news coverage, and a growing number of books, including several written by researchers in the field. More than 100 clinical trials in the past decade suggest that it is an effective strategy for weight loss. And weight loss generally comes with related health improvements, including a reduced risk of heart disease and diabetes. What is less clear is whether there are distinct benefits that come from limiting food intake to particular windows of time. Does it protect against neurodegenerative diseases such as Alzheimer’s disease, enhance cognitive function, suppress tumours, and even extend lifespan? Or are there no benefits apart from those related to cutting back on calories? And what are the potential risks?

Neuroscientist Mark Mattson at the Johns Hopkins School of Medicine in Baltimore, Maryland, and author of the 2022 book The Intermittent Fasting Revolution, has been studying fasting for 30 years. He argues that, because ancient humans went for long periods without food as hunter-gatherers, we have evolved to benefit from taking breaks from eating. “We’re adapted to function very well, perhaps optimally, in a fasted state,” he says.

Fasting’s deep roots

Fasting is far from new. Periodic abstentions from food have long been practised in many religions. In the fifth century bc, the Greek physician and philosopher Hippocrates prescribed it for a range of medical conditions.

Recent scientific interest in fasting has its roots in questions raised by research on calorie restriction. Since the 1930s, studies have shown that putting rodents on low-calorie diets can increase their lifespans. Hypotheses proposed to explain this effect include that calorie restriction slows growth, lowers fat intake or reduces cellular damage caused by unstable free radicals.

But an observation made in 1990 by researcher Ronald Hart, who was then studying ageing, nutrition and health at the US National Center for Toxicological Research in Jefferson, Arkansas, highlighted another intriguing possibility. Calorie-restricted rodents fed once daily consumed all their food in a few hours. Perhaps the calorie-restricted rodents lived longer because they repeatedly went for 20 or so hours without eating.

In the immediate aftermath of a meal, cells use glucose from carbohydrates in food as fuel, either straight away or following storage in the liver and muscles as glycogen. Once these sources are depleted—in humans, typically around 12 hours after the last meal—the body enters a fasted state during which fat stored in adipose tissue is converted to ketone bodies for use as an alternative energy source.

‘Intermittent fasting’ generally refers to various diets that include repeated periods of zero- or very low-calorie intake that are long enough to stimulate the production of ketone bodies. The most common are time-restricted eating (TRE), which involves consuming all food in a 4- to 12-hour window, usually without calorie counting; alternate-day fasting (ADF), whereby people either abstain from food every other day or eat no more than around 500 calories on that day; and the 5:2 diet, which stipulates a 500-calorie limit on 2 days per week (see ‘Three forms of fasting’).

When it was all over, Amanda Cruz felt like a phoenix, a new person rising from what had been. First, though, she had to go through the fire.

Pre-caregiving Amanda was a talker. When she was 2 years old, she always waved to everyone on the bus. In her 20s, she moved to Denmark for graduate school knowing nobody and loved it. Later, she worked for city government in a job connecting with constituents. She learned to speak Spanish so she could chat with more people.

In 2023, her mom was dealing with a cancer relapse that had progressed into her spine. That July, right before Cruz’s parents moved to her neighborhood in South Carolina to be near her, her mom also had a stroke.

Cruz helped all along, but in early 2024, she took on a lot more — meal prep, meds, following up on appointments, trips to water aerobics. She still worked at a small construction company, she still went to the YMCA for yoga and Pilates. But as she became more involved in her mother’s life, Cruz began to change.

She became quieter, and she began to listen more. She was learning to hear beyond the words her mother said to understand what she really meant. Listening to judge whether her mother needed more pain meds, or to figure out what she really wanted at that moment, even if it was just a soda from the gas station. Her own words were saved for the daily rituals of bathing, medicine, questions about pain, and gently encouraging her mother to start saying her goodbyes.” I must pull myself back to put her forward,” she said to herself.

They sheltered together in this pool of quiet while the world seemed to accelerate around them. There was another stroke in November. Afterward, on the way home from the hospital, her mother fell silent. She did not speak at all during dinner that night. Cruz knew in her gut that the words were not coming back.

Now listening became a whole-body experience, to gauge her mom’s expressions and anticipate her needs. At times, her mother screamed in pain, and she had to listen to that too.

Along the way, she lost herself. “I was erased from myself by caring for this person,” she says. “I wasn’t my personality. I didn’t do things I liked anymore.” She was a people person, but there wasn’t time or space to engage with anyone besides her mother. To tell the truth, she wasn’t even interested. She found it hard to eat. The world seemed to be monochrome.

It’s well-known that family caregiving for sick or elderly adults can bring on stress, anxiety, and depression. It can also turn you into someone you don’t even recognize. Caregivers say it scrambles old habits and patterns, rearranges intimate relationships, and forces you to confront your limits. It can excavate and reorganize the soul, what one caregiver calls mind and body fracking.

Amanda Cruz felt her whole identity was shifting. She felt entwined with her mother, body and soul, but mostly all she could do is watch her suffer. She says now that God was pressing her through her fear. Only after her mother died in December would she find out what was on the other side.

The c-word

In 2009, two researchers proposed an explanation for why caregiving for an adult who is ill or disabled can be so profound. Their argument, simply called “caregiver identity theory,” is now widely accepted among psychologists and social workers who study and help caregivers.

The first meteor shower in over months will unfold in the late-April sky. Plus, early risers will get to catch the crescent moon bunching up with three planets before sunrise.

Warmer spring weather is drawing more people outdoors, even after dark, to stargaze following the frigid nights of winter. April promises to be an exciting month for skywatchers, featuring a variety of celestial events, including the first meteor shower in more than three months.

Full Pink Moon: April 12-13

The first full moon of astronomical spring will shine brightly in the April sky during the second weekend of the month. It’s associated with the changing flora that arrives with the warming season.

April’s full moon is commonly called the Pink Moon — not because the moon changes color but because of the wild ground phlox, one of the first flowers to blossom in the spring across eastern North America. The plant features pink and purple petals.

Alternate nicknames for April’s full moon include the Frog Moon, the Sugar Maker Moon and the Breaking Ice Moon.

Lyrid meteor shower: April 21-22

Shooting stars will return to the night sky as the Lyrid meteor shower peaks on the night of Monday, April 21, into the early hours of Tuesday, April 22. This will be just the second moderate meteor shower of 2025, following the Quadrantids, which peaked on Jan. 3.

Up to 20 meteors per hour may be visible on peak night, with the best views expected during the second half of the night.

The next meteor shower after the Lyrids will be the Eta Aquarids, which will peak on the night of May 4 into the early morning of May 5.

Crescent moon cuddles up with Venus, Saturn, and Mercury: April 25

Early risers will be treated to a striking celestial display as four planets and the moon align in the eastern sky before sunrise on Friday, April 25.

Venus will shine brightly at the top of the formation, with Saturn appearing dimmer below and to the right, near the crescent moon. Mercury will be the most difficult to spot, sitting very low on the horizon in the pre-dawn sky.

CLIMATEWIRE | Top Wall Street institutions are preparing for a severe future of global warming that blows past the temperature limits agreed to by more than 190 nations a decade ago, industry documents show.

The big banks’ acknowledgment that the world is likely to fail at preventing warming of more than 2 degrees Celsius above preindustrial levels is spelled out in obscure reports for clients, investors, and trade association members. Most were published after the reelection of President Donald Trump, who is seeking to repeal federal policies that support clean energy while turbocharging the production of oil, gas, and coal — the main sources of global warming.

The recent reports — from Morgan Stanley, JPMorgan Chase and the Institute of International Finance — show that Wall Street has determined the temperature goal is effectively dead and describe how top financial institutions plan to continue operating profitably as temperatures and damages soar.

“We now expect a 3°C world,” Morgan Stanley analysts wrote earlier this month, citing “recent setbacks to global decarbonization efforts.”

The stunning conclusion indicates that the bank believes the planet is hurtling toward a future in which severe droughts and harvest failures become widespread, sea-level rise is measured in feet rather than inches and tropical regions experience episodes of extreme heat and humidity for weeks at a time that would bring deadly risks to people who work outdoors.

The global Paris Agreement, from which the U.S. is withdrawing under Trump, aims to limit average temperature increases to well below 2 degrees Celsius. Scientists have warned that permanently exceeding 1.5 degrees — a threshold the world breached for the first time last year — could lead to increasingly severe climate impacts, such as the demise of coral reef ecosystems that hundreds of millions of people rely on for food and storm surge protection.

Morgan Stanley’s climate forecast was tucked into a mundane research report on the future of air conditioning stocks, which it provided to clients on March 17. A 3 degree warming scenario, the analysts determined, could more than double the growth rate of the $235 billion cooling market every year, from 3 percent to 7 percent until 2030.

“The political environment has changed, so some of them are conforming to that,” Gautam Jain, a former investment banker who is now a senior research scholar at Columbia University, said of Wall Street’s increasingly dire climate projections. “But mostly it is a rational business decision.”

The new warming estimates come as heat-trapping gases continue to rise globally and as international commitments to limit the burning of oil, gas, and coal, that’s responsible for the bulk of emissions, have stalled. Meanwhile, megabanks like Wells Fargo are backsliding on their previous climate pledges and exiting from the Net-Zero Banking Alliance, a United Nations-backed group that encouraged members to slash their emissions in line with the Paris Agreement.

Morgan Stanley, which in October watered down its climate-related lending targets, declined to comment.

Betting on potentially catastrophic global warming is both an acknowledgment of the current emissions trajectory and a politically savvy move in the second Trump era, according to Jain.

“Nobody wants to be seen as going against,” the administration’s pro-fossil-fuel energy policy, he said. “These banks are businesses, so they have to look at the risk that they have in their portfolio and the opportunities that they see in the most likely environment.”
