Fad diets not scientifically proven, could be dangerous, warn experts

Published

 on

Even as the global prevalence of obesity is alarmingly high, some people turn to fad diets that are scientifically unproven and an unhealthy option for losing weight, experts here said noting that it can also be dangerous.

Known to be a quick fix for obesity, a fad diet looks quite appealing with several celebrities following it and sharing their experiences as well as flaunting their seemingly slim or well-toned body. Although beneficial in the short-run, studies show these may affect our health as they are not wholesome.

Some of the popular diets include Atkins, paleo, keto, vegan and intermittent fasting, among others.

“Fad diets are diets which are not scientifically proven, they usually focus on one nutrient and are not a healthy and balanced diet,” Ritika Samaddar, Chief Dietitian, Max Healthcare, told IANS.

“Following a fad diet would definitely show a positive result in terms of losing weight as one is eating less, but sooner or later will regain the weight. It is also not sustainable for long and following for a long time will lead to some deficiency and ill health. Because it show’s quick results hence people follow but fad diets are not advisable as they can have negative health impact,” she added.

A recent study, published in the Journal of Internal Medicine, showed that eating low-carbohydrate diets like Keto increased mortality risk up to 38 per cent.

Another study from the University of British Columbia in Canada showed that a Keto diet with low amounts of carbohydrates and high amounts of fats could be associated with higher blood levels of “bad” cholesterol and thus double the risk of heart attack and stroke.

Similar has been the case with the Paleo Diet that urges people to mimic pre-historic ancestors’ food choices, which includes vegetables, fruit, nuts, pasture-raised meat and wild-caught seafood while completely avoiding dairy products, cereals, pulses and processed sugar.

But a 2020 study reported that following the Paleo Diet resulted in a higher relative abundance of gut bacteria that produce a chemical associated with cardiovascular disease.

“Fad diets are not scientifically approved, and these are diets that you hear about from somebody who is doing them or trying them. As these diets are not scientifically approved, they can definitely affect your organs. One should only follow these diets after consulting a good dietician,” Arun Bhardwaj, Consultant — Minimal access and Bariatric surgery, HCMCT Manipal Hospital, Dwarka, told IANS

“There are a lot of different types of diets which have been done by people over the years such as Atkins and keto. These have benefits in the short term but are not sustainable in the long run,” added ikas Singhal, Senior Consultant, GI Surgery, GI Oncology and Bariatric Surgery, Institute of Digestive and Hepatobiliary Sciences, Medanta Gurugram, told IANS.

“Often somebody on keto or any other fad diet can become deficient in other nutrients. In the long term fad diets lead to complications,” he said.

While studies have shown intermittent fasting to boost insulin sensitivity and also prevent heart-related Covid complications, it also showed raising the possibility of fertility problems in both males and females.

In addition, a recent study, published in Annals of Internal Medicine, showed that intermittent fasting produced similar weight loss results to traditional calorie counting in adults with obesity; and its effect beyond short-term remains unclear.

“Certain diets like intermittent fasting, low carb diets, VLCD diets, meal replacement diets work, provided it has been given and explained by a certified nutritionist so that the diet is balanced in terms of nutrients and is also sustainable,” Samaddar said

“Certain fad diets like keto, liquid diets, detox diets are not recommended as they can cause severe deficiencies,” she added.

Further the experts noted that one should not blindly follow any diet by just checking on the internet, rather visit a diet specialist to avoid any harm.

So to tackle obesity the experts suggested good lifestyle habits, with exercise including brisk walk, yoga, swimming, cycling and proper diet.

“When we talk about weight loss, it is 70-80 per cent of what you eat and 20-30 per cent is exercise. Active lifestyle or daily exercise should be an important component of weight loss management,” Samadar said

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
