Feast one day, fast the next—this bold rhythm is taking the wellness world by storm. As millions chase quick weight loss fixes and fatigue over calorie-counting grows, alternate-day fasting is stepping up as a surprisingly effective strategy. Backed by a new global review involving 99 studies and more than 6,500 participants, this eating pattern may outpace both the popular 16:8 routine and strict calorie-cutting diets. And it’s not just about trimming waistlines—it could also reboot metabolism, lower bad cholesterol, and help manage chronic health conditions. Could this be the diet trend that finally changes the game?

a new study has turned the spotlight on a diet strategy that may just be more effective than traditional intermittent fasting: alternate-day fasting (ADF). Coined as the feast-and-famine method, this dietary approach involves a full 24-hour fast every other day, and it might have more potential than the popular 16:8 or 5:2 fasting regimens.

Researchers from a global collaboration spanning the US, Scotland, Germany, and Canada have uncovered promising findings in a meta-analysis that reviewed 99 clinical studies and more than 6,500 participants. The results? Alternate-day fasting led to greater weight loss than continuous calorie restriction or other intermittent fasting strategies, including time-restricted eating and whole-day fasting.

What is Feast-and-Famine Diet Trend?

Alternate-day fasting isn’t exactly new, but its newfound support comes with a stronger scientific foundation. The diet requires individuals to abstain from caloric intake every other day while allowing regular eating on non-fasting days. While this sounds more intense than the popular 16:8 schedule, where food is consumed within an eight-hour window, results seem to speak for themselves.

The average participant in the reviewed studies had a body mass index (BMI) of 31, and a significant majority (89%) had pre-existing health conditions. This makes the findings especially relevant for people dealing with metabolic concerns such as diabetes, high blood pressure, or elevated cholesterol levels.

How ADF is Different from Intermittent Fasting Diet?

Unlike time-restricted eating (e.g., 16:8) or the 5:2 method (fasting for two days each week), alternate-day fasting applies a full-day fasting protocol every other day. This means that in a typical week you would fast for about 3-4 days with no calorie consumption.

What sets ADF apart is how it influences metabolism. Studies suggest that this method can boost metabolic rate, lower LDL ("bad") cholesterol and improve insulin sensitivity. These factors are crucial for people with obesity or those at risk of developing cardiovascular disease and type 2 diabetes.

Is ADF Clinically Significant?

Despite the results, researchers caution that ADF did not meet the clinical weight loss threshold of 2 kg often targeted in obesity treatment guidelines. Still, its efficacy relative to other diets offers a compelling alternative for individuals seeking variety or faster short-term results in their weight loss journey.

The authors of the study, published in The BMJ, urge caution and call for more long-term trials. "Minor differences were noted between some intermittent fasting diets and continuous energy restriction, with some benefit for an alternate day fasting strategy with weight loss in shorter duration trials," they noted.

That said, all intermittent fasting strategies, including time-restricted eating and whole-day fasting, led to some degree of weight loss when compared to an ad-libitum diet one without any restrictions.

Experts increasingly view it as a flexible tool that can be customized within a broader, patient-centric model of nutritional care. The new findings support using ADF as part of this toolkit, especially for those who have tried and plateaued with traditional calorie-restriction diets.

According to the World Health Organization, approximately 2.5 billion adults globally are overweight, and 890 million live with obesity. With rates of metabolic syndrome, heart disease, and type 2 diabetes continuing to climb, effective, sustainable, and personalized weight management strategies are more imprtant than ever.

GLP-1 Drugs vs. Fasting: What To Choose For Weight Loss?

Coinciding with the release of this study is the NHS’s decision to allow general practitioners in England to prescribe Mounjaro (tirzepatide), a medication known for its significant weight loss effects. While effective, these medications are expensive and not without side effects.

As a result, dietary strategies like ADF offer an attractive, non-pharmaceutical option for those who may prefer or require lifestyle-based interventions.

Though ADF is proving its mettle in short-term studies, researchers emphasize the need for longer and more rigorous trials. Only with extended observation can we understand whether these weight loss benefits are sustainable, whether metabolic advantages persist and how feasible it is for individuals to stick with such a demanding regimen.

For now, ADF appears to be a promising alternative—particularly for those seeking to shake up their diet strategy or accelerate initial weight loss. Still, it should be undertaken with professional guidance, especially for individuals with underlying health conditions.

Feast-and-famine may sound extreme, but science is increasingly pointing to its potential to outperform more common intermittent fasting techniques. While not a silver bullet, alternate-day fasting offers a new hope for those grappling with weight loss or metabolic health challenges.

As with any diet, the key lies in personalization, consistency, and understanding your own body’s needs. With more long-term studies underway, ADF may soon become a more mainstream strategy for effective and sustainable weight management.

Eggs are a great source of protein. At the same time, they are one of the most common foods that cause allergies in children.

A new study conducted in Australia showed that introducing eggs to children before the age of one may reduce the risk of allergy by 17 per cent. The findings were published in the journal JAMA Pediatrics.

Jennifer Koplin, Associate Professor at the Child Health Research Centre at The University of Queensland, said: “Australia has one of the highest rates of food allergy in the world, with one in 10 infants allergic to one or more foods".

To curb the allergy rates, the Australian infant feeding guidelines, issued by the Australasian Society of Clinical Immunology and Allergy in 2016, revolutionized allergy prevention by advising parents to introduce well-cooked egg and smooth peanut butter soon after starting solid foods, generally around six months of age.

The research, led by a team from UQ and the Murdoch Children's Research Institute, examined 7,200 children in two Australian population-based studies to assess whether egg allergy rates had declined since the introduction of the guidelines. The risk of allergy decreased by 17 per cent among babies who started eating eggs early.

“Most parents followed the guidelines, and these results provide reassurance that this advice will help reduce the chance of their child developing an egg allergy,” Dr Koplin said.

Lesser Allergy In Infants With Eczema

According to Associate Professor Rachel Peters of the Murdoch Children's Research Institute, the reduction in egg allergy was more pronounced in babies with eczema, a known risk factor for food allergies. Among these children, egg allergy rates were reduced from 35 per cent to 22 per cent.

“The introduction of the 2016 guidelines was a major change from most advice given in the 1990s and early 2000s, which recommended parents delay giving eggs and other allergenic foods until 1–3 years of age if there was a strong family history of allergy,” Dr Peters said.

Allergenic Foods Before Age One

Other common allergy-causing foods, such as cow's milk, fish, sesame, wheat, and tree nuts, are also recommended to be included in a child's diet before one year of age. Dr Koplin, however, urged for more research into food allergies.

Common Symptoms of Egg Allergy

According to the Mayo Clinic, egg allergy symptoms usually start a few minutes to a few hours after eating eggs or foods containing eggs. While egg allergies can occur as early as infancy, most children outgrow their egg allergy by age 16.

Egg allergy symptoms can include:

• Skin swelling or itchy bumps called hives — the most common egg allergy reaction.
• Stuffy or runny nose and sneezing, also known as allergic rhinitis.
• Digestive symptoms such as cramps, upset stomach and vomiting.
• Asthma symptoms such as coughing, wheezing, chest tightness or shortness of breath.

Food is arguably one of the most important parts of life, as it is essentially the fuel that the body runs on. Food is so important to life that slight complications, changes, or missteps can cause great harm to you. If the food is unsafe, then that can act like poison as well. According to the World Health Organization (WHO), unsafe food causes around 866 million illnesses and 1.5 million deaths every year.

The WHO, in its recent report, reveals that children under 5 years of age experience 29 per cent of the health burden due to unsafe food, with 143,000 deaths in 2021.

WHO Director-General Dr Tedros Adhanom Ghebreyesus said, “Food safety is not an abstract issue – it touches every meal, every family, every day. Unsafe food has always been a major public health concern, but until now, we lacked the bigger picture of its staggering human and economic toll. These new estimates change that.”

Thus, it is crucial to know what to eat, how to eat, and protect yourself from foodborne diseases. And there is a strong connection between unsafe food and food myths; misunderstandings in the kitchen can cost you dearly, so knowing popular food myths from the global health body, WHO, is crucial.

5 Dangerous Food Safety Myths

Can You Tell If Food Is Safe To Eat By Its Look And Smell?

People often think that the smell and appearance of food can help us know its condition, but it's a complete hoax, as the WHO reports that most microorganisms that can make you sick don’t change the look or smell of the food.

Should Raw Poultry Be Washed Before Cooking?

This is arguably one of the popular food-related misconceptions, as in most households, the washing of chicken before cooking is seen as a healthy practice emphasizing making sure that the raw meat has been properly washed and soaked, but the WHO's report proves otherwise. The global body, washing poultry can spread harmful microorganisms to hands, surfaces, utensils, or other food.

Do Organic Fruits And Vegetables Need To Be Washed?

Some think that fruits and vegetables grown organically do not require washing, as they are not cooked with pesticides or chemical fertilizers, and that is a myth. The WHO said all produce, including organic, should be washed with clean water to remove physical contaminants and reduce the risk from any harmful microorganisms or chemicals.

Can Dishcloths Spread Dangerous Bacteria?

Another common habit is to use dishcloths to clean them after washing, and that is a big no from WHO, as dishcloths and sponges can carry and spread dangerous bacteria.

Do I Have To Refrigerate Leftover Food?

Sometimes people do not keep leftover food outside the refrigerator, and that is also a mistake because food can be dangerous to consume if left at room temperature for more than two hours.

Prediabetes affects more than 600 million people worldwide and is linked not only to an increased risk of type 2 diabetes but also to impaired brain function.

Adding a small quantity of almonds to the daily diet on their own or added to cereal, yogurt, curries, salads, and other dishes may help boost brain health and prevent a decline in cognitive function in adults with prediabetes, experts said.

Almonds contain

• protein
• fiber
• saturated fat and unsaturated fat
• 24 essential nutrients, including magnesium, potassium, and vitamin E.

The findings showed that eating just a few almonds each day may benefit cognitive performance, metabolic health, and markers of inflammation and oxidative stress in middle-aged Asian Indian adults with prediabetes.

“Adults with prediabetes are vulnerable to a decline in cognitive function. Our study indicates that just one simple dietary change – adding a small quantity of almonds to the daily diet – may help support brain health and improve cognitive performance in some populations,” said Dr. Anoop Misra, co-investigator and Chairman, Fortis-CDOC Center of Excellence for Diabetes, Metabolic Diseases, and Endocrinology in New Delhi, part of the study.

He noted that daily almond consumption could help lower the risk of prediabetes progressing to type 2 diabetes, a condition associated with an increased risk of dementia.

How Was The Study Conducted?

In a 24-week study, 60 Asian Indian adults aged 40–60 with prediabetes were assigned to either a control group or an almond group.

Those in the almond group consumed 32–42 grams of almonds daily as part of a calorie-matched diet.

Researchers assessed cognitive performance, blood sugar levels, cholesterol, weight, BMI, and waist circumference before and after the study.

What Did Researchers Find?

Participants in the almond group experienced improvements in executive function and processing speed, both key measures of cognitive performance.

They also demonstrated better blood sugar control, including lower fasting blood glucose, lower blood glucose levels two hours after eating, and improvements in HbA1c, a marker of long-term blood sugar control.

Additional metabolic benefits included significant reductions in body weight, body fat, BMI, waist circumference, total cholesterol, and LDL cholesterol.

Participants consuming almonds also showed improvements in markers related to inflammation and oxidative stress.

“The findings showing improvements in cognitive function, blood sugar control, body weight, and cholesterol levels reinforce the role of almonds as a superfood. Their versatility and convenience make them an easy addition to everyday eating habits, while also providing important nutrients that support overall well-being,” said Ritika Samaddar, Regional Head, Department of Clinical Nutrition and Dietetics, Max Healthcare.

“Inflammation and oxidative stress are associated with cognitive decline. Our study found those in the almond group had lower levels of both, along with higher levels of a protective antioxidant (Vitamin E), compared with the control group,” said Dr. Seema Gulati, lead researcher of the study and Head of the Nutrition Research Group at the National Diabetes, Obesity and Cholesterol Foundation in New Delhi.
