GLP-1 meds and Yom Kippur fasting: practical safety guidance

People taking GLP-1 medications (e.g., Ozempic, Mounjaro, Wegovy, Zepbound) can usually fast for Yom Kippur, but should plan with a clinician. For weekly injections, keep to the schedule; daily regimens may require timing adjustments, and oral GLP-1 pills are taken on an empty stomach, which may conflict with fasting. Those with diabetes face higher risks of lows when GLP-1s are used with other glucose-lowering drugs like insulin or sulfonylureas, so dosing and timing should be discussed with a doctor. Prefast meals, hydration, and blood-sugar monitoring are important; break the fast with a gentle, balanced meal and quick carbohydrates if needed. Seek medical guidance before fasting, especially if diabetes is not well controlled or if kidney issues or GI side effects are present.

Extended daily meal gaps linked to faster multimorbidity in older adults

Extended daily meal gaps linked to faster multimorbidity in older adults

A Swedish study of 2,981 adults aged 60+ followed for up to 15 years found that the longest daily interval between meals was associated with faster accumulation of chronic diseases, particularly among those 78 and older. The association appeared across cardiovascular and neuropsychiatric conditions but not musculoskeletal diseases, and the study cannot establish causation, relying on self-reported meal timing to estimate fasting duration.

Dark-chocolate aroma boosts repetitions in fasted workouts, study finds

A small study of 23 fasted men found that sniffing a dark chocolate scent before leg extensions increased repetitions by about 18 compared with a neutral water scent, with milk chocolate yielding about 9 more reps. The effort rating did not change, suggesting a brain-driven cue rather than muscular changes; the study notes limitations including a small, all-male sample and focus on a single exercise.

Big Review Finds Short-Term Fasting Leaves Brainpower Largely Unchanged

Big Review Finds Short-Term Fasting Leaves Brainpower Largely Unchanged

An analysis of 63 studies (3,484 participants) found no meaningful difference in cognitive performance between short-term fasters and those who eat regularly, with median fasting around 12 hours. Some modest declines appear when fasting exceeds 12 hours and in children/teens, especially on food-related tasks; neutral tasks are largely unaffected and performance may dip later in the day during fasting. The authors frame fasting as a personal tool, not a universal prescription, recommending medical guidance for individuals considering fasting.

Seven-Day Fast Triggers Deep Molecular Changes After Day Three

Seven-Day Fast Triggers Deep Molecular Changes After Day Three

A seven-day water-only fast drives broad molecular shifts that become most evident after about three days, including changes in hundreds of circulating proteins linked to the extracellular matrix and brain support, alongside a switch from glucose to fat and about 5.7 kg of weight loss. Refeeding largely reverses lean-tissue loss while fat loss persists. These findings could inform therapies that mimic fasting’s benefits for metabolism, aging, and neurological health, though prolonged fasting carries risks and should be medically supervised.

After 50, Fasting Might Backfire, Doctors Warn

After 50, Fasting Might Backfire, Doctors Warn

Doctors warn that extreme fasting or overly restrictive diets can harm health, especially after age 50, by causing malnutrition, hormonal imbalance, muscle and bone loss, fatigue, and dizziness; intermittent fasting may help some, but sustainable, nutrient-rich calorie reduction is more reliable for long-term health, mobility, and quality of life.

Fasting Generally Doesn’t Impair Adults’ Thinking, Large Review Finds

Fasting Generally Doesn’t Impair Adults’ Thinking, Large Review Finds

A sweeping meta-analysis of 63 studies (3,484 participants) finds no meaningful difference in cognitive performance between fasted and fed healthy adults. Age matters (children fare worse when fasting); longer fasts may lessen performance gaps as ketones supply energy; testing later in the day and the presence of food cues can influence results; and the type of cognitive task matters. Overall, fasting appears compatible with maintained mental sharpness in adults, with caveats for kids and certain contexts, while metabolic benefits like autophagy and improved insulin sensitivity are noted but vary by individual.

Graphic shows the body's 36-hour fasting journey: from glucose burn to autophagy

A graphic visualization explains what happens during a 36-hour fast: the body shifts from burning stored glucose to fat via ketosis, autophagy begins as nutrients run low and cellular repair accelerates after 24 hours, with peak autophagy around the 36-hour mark. The piece also notes health risks for certain individuals, stresses medical supervision, and cites studies suggesting limited eating windows may carry long-term risks.

8 Proven Strategies to Lower Your Cancer Risk

The article provides eight scientifically supported tips to lower cancer risk, including optimizing vitamin D levels, practicing intermittent fasting, adopting a low-carb diet, exposing oneself to cold therapy, cooking smarter, consuming anti-cancer foods, staying physically active, and maintaining a healthy lifestyle overall. While these strategies do not guarantee cancer prevention, they can significantly reduce the risk and improve overall health.

Research Finds Skipping Breakfast Does Not Harm Brain Function

A comprehensive review of 71 studies found that fasting does not impair cognitive performance in healthy adults, though it may affect children, adolescents, and specific situations like late-day testing or food-related tasks. The research suggests fasting can be a safe health practice for most adults without sacrificing mental sharpness, but caution is advised for certain groups.

Cardiologist Shares Fastest Methods to Lose Visceral Belly Fat

Cardiologist Shares Fastest Methods to Lose Visceral Belly Fat

Dr. Pradip Jamnadas, a cardiologist with over 31 years of experience, recommends a gradual fasting routine starting with 12-12 hours and progressing to 18-6 hours to effectively and safely reduce visceral belly fat, which is linked to heart health issues. For severe cases like diabetes or significant obesity, he suggests more extended fasts such as 48-hour fasts or OMAD. The approach emphasizes hydration and gradual adaptation, highlighting fasting as a healing and fat-burning tool rather than starvation.
