New Delhi, Oct 1 (IANS) Finding it hard to manage blood sugar levels? Take heart, limiting your food consumption to a 10-hour window daily may keep your diabetes in check, according to a study.

ntermittent fasting (IF) has become one of the most talked-about health trends in recent years. From weight loss to better blood sugar control, its benefits are widely praised.
But what about older adults? Can people over 60 safely try intermittent fasting—and more importantly, does it actually help?
Let's explore the science and expert advice behind fasting in the later decades of life.
What is Intermittent Fasting, Exactly?
Intermittent fasting doesn't focus on what you eat, but when you eat. The most common pattern is the 16:8 method—16 hours of fasting followed by an 8-hour window to eat.
There's also the 5:2 method, where you eat normally for five days and cut down calories (about 500-600) on two non-consecutive days.
These patterns allow the body to rest from constant digestion, encouraging fat-burning and cellular repair.
Is Intermittent Fasting Safe for Seniors?
Yes, with caution. For healthy adults over 60, intermittent fasting can be safe—but it depends on individual health conditions and lifestyle.

Seniors often have different nutritional needs, medications, or chronic conditions that must be considered.
According to a
review
, intermittent fasting may offer metabolic benefits for older adults, including improved insulin sensitivity and reduced inflammation. But skipping meals can also lead to fatigue, dizziness, or nutrient deficiencies if not done right.
Potential Benefits of Intermittent Fasting After 60
1. Better Blood Sugar Control
Fasting may help regulate insulin levels and reduce blood sugar spikes.
This can be helpful for seniors managing prediabetes or type 2 diabetes—although medication timing must be monitored carefully.
2. Weight Management
With age, metabolism slows down and losing weight becomes harder. IF can create a natural calorie deficit, which may support healthy weight loss—especially around the belly.
3. Cellular Repair and Brain Health
Fasting activates autophagy, the body's process of cleaning out damaged cells.
Some studies suggest this may have protective effects on brain aging and cognitive health.
4. Reduced Inflammation
Chronic inflammation is linked to many age-related diseases. Intermittent fasting may lower inflammatory markers in the body, according to research published in Frontiers in Nutrition (2020).
Possible Risks Seniors Should Watch Out For
1. Low Energy or Dizziness
Older adults may become light-headed if fasting too long, especially if they have blood pressure or blood sugar issues.
2. Nutrient Deficiencies
Eating fewer meals means fewer chances to get essential nutrients like calcium, vitamin B12, and protein—important for muscle and bone health in seniors.
3. Medication Conflicts
Fasting can interfere with medications that require food, such as those for diabetes, thyroid, or heart conditions.
Smart Tips for Seniors Trying Intermittent Fasting
Start slowly: Begin with a 12:12 or 14:10 schedule before moving to longer fasts.
Stay hydrated: Drink plenty of water, herbal teas, and broth during fasting hours.
Prioritize nutrient-rich meals: Focus on whole foods rich in fiber, protein, and vitamins.
Avoid heavy workouts while fasting: Especially if you're new to it or taking medications.
Always consult a doctor: Get personalized advice before starting IF, especially if you have health conditions or are on medications.
Final Verdict: Is It Worth Trying?
Intermittent fasting can be both safe and effective for many adults over 60—but it's not a one-size-fits-all. When done thoughtfully and with medical guidance, IF may offer benefits like improved metabolism, better weight control, and even cognitive support.
However, the priority should always be balanced nutrition, regular physical activity, and maintaining energy levels to support healthy aging.

Rims doubles cottage charges, hikes paying ward fee for patients to earn more revenue
1 2 3 Ranchi: Patients seeking admission at Rajendra Institute of Medical Sciences (Rims) will now have to pay more to access cottage and paying ward facilities. The hospital administration has revised its fee structure, doubling the daily charge for cottages from Rs 250 to Rs 500, while the rent for the paying ward increased from Rs 1,000 to Rs 1,500 per day. The hike, which came into effect a few days ago, has drawn mixed reactions from the public and patient families. The Rims management on Friday justified the revision stating that the previous rates remained unchanged for many years. "The move will help the hospital to earn more money, which can then be pumped into infrastructure and development," an official said. The paying ward is in relatively better condition, with functional infrastructure and cleanliness maintained to some extent. There are 16 cottages in total at Rims. Currently, seven rooms on the first floor are being used as emergency wards, while the ground floor cottages are being allotted as paid accommodation. Seven beds are equipped with oxygen supplies. The paying ward has a capacity of 100 beds. To ease pressure on overcrowded emergency and critical care units, Rims has shifted stable, recovering patients to underutilised cottage and paying wards. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo The move aims to free up emergency beds for critically ill patients. Patients transferred to the cottage and paying wards under this system are not being charged for their stay. Only patients who voluntarily opted for treatment in the cottage or paying wards are required to pay the respective charges of Rs 500 and Rs 1,500 per day. Those shifted as part of the hospital's internal allocation are exempt from any fees. Emergency and critical care wards together have around 130 beds. Rims public relations officer Dr Rajeev Ranjan said, "The shift was intended to streamline patient management and reduce wait times in emergency situations. By separating recovery-phase patients, the hospital aimed to enhance the overall quality of care." Get the latest lifestyle updates on Times of India, along with Eid wishes , messages , and quotes !

Filthy floors, littered waiting area leave GMCH-32 ailing
1 2 Chandigarh: The Government Medical College and Hospital (GMCH), Sector 32, is under fire after its OPD waiting area and corridors were found strewn with garbage, raising serious questions about hygiene and cleanliness in one of the city's busiest healthcare facilities. Broken water bottles, paper plates, juice tetra packs, and polythene waste littered the waiting area, giving the entire OPD complex an unhygienic appearance. Patients and attendants were seen waiting in discomfort, with chairs surrounded by trash and a persistent foul smell emanating from blocked washroom drains and washing areas. A visit to the hospital on Wednesday revealed that sanitation in key areas of the hospital has taken a serious hit. The condition of washrooms, in particular, was deplorable, with overflowing sewerage and blocked drains making them unusable for many patients. Jeevan Kumar, a patient who visited the OPD for a check-up, expressed shock at the state of the premises. "The waiting area was full of filth. Chairs installed for patients were surrounded by used bottles, juice packs, and other garbage. How can a hospital, which is supposed to promote health and healing, be in such a filthy condition?" he questioned. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like American Investor Warren Buffett Recommends: 5 Books For Turning Your Life Around Blinkist: Warren Buffett's Reading List Undo Social activists and political leaders also raised the alarm. Local BJP leader and social activist Shashi Shankar Tiwari said, "It is disheartening to see the hospital in such a state, especially as we approach the monsoon and potential resurgence of infections. The sanitation standards are abysmal—it feels like we are back in the COVID era. The hospital waiting area gives a grim picture of neglect and administrative apathy. " "Hospitals must lead by example when it comes to hygiene. What message are we sending when one of our top medical institutes is drowning in garbage?" said a health rights activist. GMCH-32 medical superintendent Dr Gurvinder Singh acknowledged the issue and assured prompt action. "I will get the area checked and ensure that the garbage is cleaned immediately. We will also pull up the sanitation staff for negligence," he said. BOX Patients forced to pay in cash The Government Medical College and Hospital (GMCH), Sector 32, has come under criticism yet again—this time for its failure to accept online payments. Patients visiting the hospital are being forced to make payments in cash at billing counters, leading to inconvenience and allegations of petty overcharging due to unavailability of change. According to complaints, the staff at payment windows are not accepting card-based transactions and insist on cash payments. Several patients have reported being made to run around in search of change, with some even giving up small excess amounts at the counters. A patient visiting the ENT department recounted his ordeal. "The payment clerks made me run for around 20 minutes arranging for change to make a payment. Eventually, I managed to get change from a security guard. I also witnessed some patients ahead of me in line forgoing Rs 10 or Rs 20 just because they didn't have exact change and the staff refused to return the difference," he said. The absence of Point of Sale (PoS) machines at payment windows has raised eyebrows, with some patients questioning whether the situation is being deliberately misused. "When the hospital can adopt digital methods in recordkeeping and diagnostics, why can't basic payment systems be digitised?" questioned a relative of a patient in the medicine OPD. GMCH-32 Medical Superintendent Dr. Gurvinder Singh said, "This cannot be considered a routine practice. It is possible that PoS machines were not working due to technical issues or server problems. We will have to check the situation and get back with appropriate measures."
