Give up dinner? Landmark study shows daytime eating could be the new fountain of youth.
Breakfast people are happy.

Eating less could lead to a longer life.
Ever since Clive McCay published his landmark 1935 study that showed mice with severely restricted diets lived 33% longer, many have wondered whether caloric restriction could extend the human life span, too.
It makes for an interesting philosophical question: Would you trade the joy of eating for a longer life?
There are a few reasons why some say this type of caloric restriction could work to extend human life spans. First, larger animals tend to live longer than smaller ones because they have slower metabolic rates. When we consume fewer calories, we have less to metabolize.
Second, it’s speculated that caloric restriction reduces free radical damage in the body, slowing the aging process.
When it comes to dietary restriction, it\u2019s not just calories that count. A study @ScienceMagazine shows that timing feedings to match active period of circadian cycle extended life span of mice more than three times as much as caloric restriction alone.https://www.eurekalert.org/news-releases/951907\u00a0\u2026— Buck Institute (@Buck Institute) 1652123224
A new study out of UT Southwestern on mice has found that caloric restriction increases longevity, which isn’t exactly front-page news. However, the intriguing part is that this study found that the time of day the mice were fed had a big effect on their life spans.
Researchers found that restricting the calories mice ate by 30 to 40% increased their longevity by 10%. But mice that were fed the restrictive diet only while active at night lived 35% longer than those that ate whatever they wanted whenever they chose.
If this type of diet were adapted for a human’s biological rhythms, we’d eat low-calorie diets during the daytime. So if you’re the type that prefers breakfast over dinner, a long life could be in the cards. But if you love a four-course dinner, it may be hard to make the adjustment.
Bottom line: If the diet is found to work the same way in humans as it does for mice, when we eat will become almost as important as what we eat. It could also lead to changing the times we wake up and go to sleep. Who wants to stop eating at 3 p.m. and then go to bed hungry at 11 p.m.?
“It’s pretty clear that the timing of eating is important to get the most bang for your buck with calorie restriction,” Dr. Joseph Takahashi, Ph.D, one of the lead researchers on the study, said in a news release.
“We have discovered a new facet to caloric restriction that dramatically extends life span in our lab animals,” said Dr. Takahashi, the Loyd B. Sands Distinguished Chair in Neuroscience. “If these findings hold true in people, we might want to rethink whether we really want that midnight snack.”
The study also makes the interesting case that low body weight isn’t necessarily tied to longevity.
“This shows that at low body weight, this popular yardstick of health (body weight) is not a predictor of life span,” said Dr. Carla Green, Distinguished Scholar in Neuroscience at UT Southwestern.
Obviously, this study was performed on mice and there’s a long way to go before we can be sure that this type of drastic dieting will expand human life or doesn’t come with any dangerous side effects. But it is compelling to imagine that by simply adjusting what and when we eat we could live up to 35% longer.
That would push the life span of the average American male from 75 to 103 and female from 81 to 109.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.
A woman in black long sleeve shirt stands in front of mirror.
Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
