Hidden clue reveals how long you'll live as scientists warn of 'serious problems' lurking in your body

Daily Mail​21-07-2025
Carrying extra fat around your belly, even if you are not overweight, can quietly take away your strength and shorten your life without warning, scientists warns.
A recent study found that people with thicker waists compared to their height or hips are more likely to struggle with movement as they age, and face a higher risk of premature death.
Researchers said it is not how much you weigh, it's about where you carry it. And belly fat is a major red flag for your body.
A team of Italian scientists tested 10,690 adults over six years using a simple sit–and–stand test performed five times from a chair.
Dr Elena Levati, the lead researcher and surgeon at Agostino Gemelli University Hospital Foundation in Italy, wrote: 'This can help identify people at risk before more serious problems show up.'
The study found that people were 28 percent more likely to have trouble moving if their waist was wide compared to their hips, and 32 percent more likely if their waist was too large for their height, regardless of their weight or age.
According to a report of Centers for Disease Control and Prevention, about 40.3 percent of adults in the US classify as obese, which is more than 100 million people.
The CDC says that the belly fat, especially the kind that builds up around organs, raises the risk of heart disease, stroke, type 2 diabetes, and early death.
The study published in Aging focused on two numbers, the waist to hip ration (WHR) and the waist to height ratio (WHtR).
Experts note that WHR and WHtR have been used in clinical trials for years to identify risks for heart disease and diabetes.
The recent study, however, explored WHtR's link to age-related muscle decline, testing how quickly patient's muscle function deteriorates with aging.
Researchers collected participants' waist and hip measurements, had them complete questionnaires about their diet and exercise, and took blood samples to check cholesterol and glucose levels.
They discovered that about 71 percent of men and 53 percent of women had risky waist-to-height ratios. For waist-to-hip ratios, 61 percent of men and 39 percent of women had unhealthy scores.
During the test, participants were timed as they stood up and sat down from a chair five times. On average, women took 7.9 seconds to complete it, while men took 7.6 seconds, both within the normal range for their age groups.
However, the study found that people with larger WHR or WHtR ratios consistently performed worse on this test. Even after adjusting for weight, age, and other factors, these participants were more likely to show signs of declining physical ability.
Although a duration longer than 10.8 seconds is typically regarded as a warning sign for frailty or disability, the researchers found that slower performance in individuals with higher belly fat ratios indicates that their muscular function may be compromised, even if they have not yet crossed that danger threshold.
Another study published by National Institutes of Health (NIH) found that older adults, with abdominal obesity and low handgrip strength, face twice the risk of death from any cause.
This combination highlights accelerated aging and increased vulnerability to weakness, disability, and premature death.
Researchers said the root cause of this issue might be the visceral fat, a type of body fat stored deep within the abdominal area, surrounding vital organs like the liver, intestines, and stomach.
Since visceral fat wraps around the organs, it has been linked to inflammation, poor muscle quality, and sarcopenia, a condition where muscle strength declines with age.
Nearly 50 percent of American adults have unhealthy waist sizes linked to excess abdominal fat, based on National Health and Nutrition Examination Survey (NHANES) data.
This kind of fat buildup can quietly affect your balance, endurance, and even how your heart and lungs work during exercise, according to the experts.
They added that unlike body weight or body to mass index (BMI), which sometimes can be misleading, these waist ratios give a clear picture as someone with normal BMI still can carry dangerous belly fat.
The study also found that waist–to–height ratio was a better predictor than waist–to–hip ratio. It was more accurate for both men and women, and worked better regardless of age.
In fact, just measuring your waist and comparing it to your height may be the simplest way to know if your future mobility is at risk.
The waist–to–height test has another advantage, it is quick, cheap, and does not require a lab or doctor's visit.
While the study focused on physical performance, the implications go beyond that. Poor mobility has been tied to higher death rates, hospitalizations, and reduced quality of life.
A study published in NIH in 2023 found that older adults with high waist circumference were significantly more likely to develop a disability within five years, even when their overall weight stayed stable.

Brown University does deal with Trump administration to restore $50m in funds

Brown University has reached an agreement with the Trump administration that will reinstate nearly $50m in research funding and close several federal investigations into the institution, university president Christina Paxson announced in a campus-wide email on Wednesday. The settlement follows the Trump administration's threat in April to freeze $510m in federal support to Brown. This makes Brown the third Ivy League school to reach a resolution with the federal government this month. Under the terms of the agreement, Brown will commit to nondiscrimination in both admissions and campus programs, and will grant federal officials access to its admissions data. The arrangement brings to an end investigations led by the Departments of Health and Human Services, Education and Justice. A statement from the institution said that the 'voluntary agreement will reinstate payments for active research grants and restore Brown's ability to compete for new federal grants and contracts, while also meeting the core imperative of preserving the ability for our students and scholars – both domestic and international – to teach and learn without government intrusion'. Unlike Columbia University, which agreed to pay a $200m settlement, Brown's deal does not involve any financial penalty or require the school to formally admit any wrongdoing. The email stated that 'the government does not have the authority to dictate teaching, learning and academic speech.' The education secretary, Linda McMahon, had previously described the Columbia settlement as a 'roadmap', predicting it would 'ripple across the higher education sector and change the course of campus culture for years to come'. In addition to a pledge to 'reaffirm compliance with nondiscrimination laws' in admissions and programs, the deal also prevents Brown from administering gender-affirming surgeries to minors or prescribing puberty blockers. The university has also agreed to implement the Trump administration's definitions of male and female (as outlined in a January executive order) for women's athletics, student programs, campus facilities and housing.

Resident doctors fear unemployment due to lack of training places

Many resident doctors are facing unemployment this summer because insufficient training places have been funded in Wales, a union has doctors - formerly known as junior doctors - can start speciality training after two years, to progress their careers and pursue a particular area of medicine such as neurology, dermatology or general a survey by doctors' union BMA Cymru Wales suggests as many as 40% are facing unemployment as there are not enough training told the union they had applied for 30 posts without securing an Welsh government said it was working with governments across the UK to explore solutions. BMA Cymru Wales said Health Education Improvement Wales (HEIW) recommended expanding the number of specialty training places to cope with the growing number of people training to be doctors in claimed that had not been taken on board by the Welsh graduation, resident doctors carry out two years of foundation training, but can start specialty training after two years, to become a BMA claim that data obtained through freedom of information requests shows a significant increase in the number of applicants for these places across the UK, without a corresponding rise in the number of places Welsh government said there had been an increase of 342 specialty training posts and 222 foundation the survey by BMA points to dissatisfaction among resident doctors who were not on their preferred career said: "I have had to apply for over 200 jobs to secure a slot that's below my level and doesn't advance my career." Chairman of the BMA's Welsh resident doctor committee Dr Oba Babs-Osibodu said: "At a time when Wales needs more doctors, there are limited opportunities for resident doctors to develop their careers in the country where they trained."Earlier this year, we wrote to the cabinet secretary for health and social care warning him of the potential impact of not expanding training places, including medical unemployment."The anonymous survey heard from one doctor: "I was unemployed for several months and despite travelling nationally for any locum shifts available, I was unable to get enough to pay all bills. Locum shifts are scarce."Another said: "I've acquired tens of thousands of pounds of student and personal debt funding medical school and now struggle to find a job. I've applied for emergency medicine training two years in a row, a specialty desperate for extra trainees, but the number of jobs haven't increased." Dr Babs-Osibodu added: "Doctors are now forced to seek ad hoc locum work, leave Wales, or leave the profession altogether. Poor workforce planning and chronic underfunding of the NHS has led to a national shortage of doctors in Wales."This is unsafe for patients, and we need to see urgent intervention from the Welsh government, including legislation to provide safer staffing levels and an expansion in specialty training places."By alleviating bottlenecks in the training pipeline, we can enable doctors to progress their careers and provide the specialist care that patients desperately need."The Welsh government said: "We're currently investing £294m into health professional education and training in Wales."We have supported a significant increase in the number of postgraduate medical training posts and since 2019, there has been an increase of 342 specialty training posts and 222 foundation posts. We now have approximately 1,900 trainees in secondary care training programmes, and 900 in foundation training, as well as 160 GP training places every year."We continue to work closely with governments across the UK to explore solutions."

New York detectives head to gunman's home in Nevada amid calls for gun control

NEW YORK, July 30 (Reuters) - New York City detectives investigating this week's mass shooting were interviewing the attacker's associates in his home state of Nevada on Wednesday, as gun safety advocates expressed dismay that he was able to buy a gun there legally last month despite two reported mental health hospitalizations. Authorities say Shane Tamura, 27, drove from his Las Vegas home to Manhattan, marched into an office skyscraper on Monday and fatally shot four people, including an off-duty police officer, with an assault-style rifle before taking his own life. Tamura legally purchased a revolver in Nevada in June at a gun store, New York police said, even though, according to multiple news reports, he was hospitalized under an emergency "mental health crisis hold" in 2022 and again in 2024. The details of those episodes were not known. Authorities have said Tamura carried a note on Monday in which he claimed he suffered from chronic traumatic encephalopathy, or CTE, a brain disease linked to football and other contact sports that can affect behavior. The disease can only be confirmed after death. New York City's medical examiner said in an email that Tamura's brain would be examined as part of a complete autopsy but did not say whether it would be screened for CTE. Tamura, who shot himself in the chest on Monday, bought the rifle he used in the attack from a supervisor at the casino where he worked for $1,400, CNN reported on Wednesday, citing law enforcement sources. Nevada law requires private gun sales to go through a licensed firearms dealer and include a background check. Whether he obtained the rifle legally or not, advocates for stricter gun laws said the case showed a need for tougher regulations nationwide, especially for people with mental health problems. "It is horrifying ... that a man with documented mental health struggles was able to purchase a weapon, let alone a weapon of such devastating capability," New York City mayoral candidate Zohran Mamdani told reporters on Wednesday, urging a national ban on assault rifles. New York is one of 10 states that bans such weapons, according to the advocacy group Everytown for Gun Safety. The National Rifle Association, the New York State Firearms Association and the New York State Rifle & Pistol Association did not immediately respond to requests for comment. The groups oppose restrictions on guns as an infringement on individual rights. Under Nevada law, officers can detain individuals on emergency holds in mental health facilities or hospitals for up to 72 hours for evaluation. In a handful of states including New York – which has some of the strictest gun laws in the nation – such emergency holds trigger some version of a ban on possessing guns, according to experts. But in most states, including Nevada, as well as under federal law, only a court-ordered involuntary commitment results in a prohibition on buying and owning guns. "What this shooting in New York highlights more than anything else is that we're only as safe as the laws of the weakest state," said Nick Suplina, Everytown's senior vice president for law and policy. Nevada has enacted a series of gun limits since an October 2017 mass shooting that killed 58 people in Las Vegas. Giffords, another gun safety advocacy organization, gave Nevada a "B-" grade in its annual scorecard of gun laws, compared with an "A" for New York. A new Nevada law that took effect this month – too late to apply to the Manhattan shooter – allows law enforcement officers to take away guns temporarily from someone who is on an emergency mental health hold. The officer can also petition a court to retain the guns if the person is deemed a danger to themselves or others. That law is similar to Nevada's "red flag" statute, which allows law enforcement or relatives to ask a court to seize firearms from anyone considered a risk. Twenty-one states have enacted red-flag laws, according to Everytown for Gun Safety. Tamura was able to obtain a concealed carry permit in 2022, according to news reports, although it was unclear whether he did so before or after his first hospitalization. His permit would have allowed him to buy the revolver last month without a background check under state law.
