Water Only Fasting: More Harm Than Help?
By: Kashmik Singh Chouhan
Popular on social media for quick weight loss and 'mental clarity,' but experts now warn it could be doing more harm than good.
University of Sydney researchers studied 20 adults who fasted with water only for 10 days, followed by 5 days of refeeding.
1. Study Details
Participants lost about 7.7% of their body weight and saw a 6% drop in waist size dramatic results in just 10 days.
2. Rapid Weight Loss
Contrary to expectations, fasting raised inflammatory proteins (like CRP and IL-8), not lowered them potentially straining the immune system.
3. Spike in Inflammation
Markers showed the body was breaking down muscle and bone fueling weight loss, but at a physical cost.
4. Muscle and Bone Stress
Fasting may reduce amyloid proteins (linked to Alzheimer's), but experts still caution about its impact on memory and cognition.
5. Memory and Focus Risks
Fasters reported headaches, insomnia, and low blood pressure signs water only fasting isn't easy on the body.
6. Headaches and Dizziness
Experts warn people with heart or blood vessel issues should avoid water only fasting it can raise risks instead of helping.
7. Heart and Vascular Strain
Results are based on 20 participants. Effects vary. Experts stress the importance of medical supervision for prolonged fasting.
8. Not a One Size Fits All
Yes, water fasting offers fast weight loss but the bodily costs, including inflammation, muscle loss, and memory risk, may outweigh the benefits. A safer alternative? Consult a doctor and try balanced, guided approaches instead.

Are you always stressed? It can affect your brain, says neurologist; know these 5 tips to manage stress
Being constantly under stress can affect general wellbeing. It can affect the heart, brain, and ruin our mental health as well. In an interview with HT Lifestyle, Dr. Neha Pandita, consultant - neurology and clinical lead - Parkinson's disease and movement disorders, Fortis Escorts, Okhla Road, New Delhi focused on how chronic stress can affect our brain. Also read | Are you always stressed? Expert shares how your gut health may be silently paying the price Stress silently shapes your brain health.(Shutterstock) 'When the body is constantly being put on alert, it releases stress hormones such as cortisol. Healthy in small amounts, repeated cortisol exposure over a period of time can weaken the hippocampus, which is the area of the brain that handles memory and learning. This may lead to problems with concentration, decision-making, and even cognitive decline later in life,' the neurologist said. 'Chronic stress also causes inflammation and disrupts neuron-to-neuron transmission. It has also been linked to psychiatric conditions such as anxiety, depression, and susceptibility to neurodegenerative diseases like Alzheimer's. It can also decrease brain areas responsible for emotion regulation and self-command, hence making stress control more challenging in the long run,' said Dr Neha Pandita. Also read | Always stressed? 6 signs that indicate your body has high cortisol levels Chronic stress can lead to psychiatric conditions.(Shutterstock) Tips to manage chronic stress: The neurologist further noted down methods to manage chronic stress and have a healthier life: 1. Mindfulness and meditation: Mindfulness practice and meditation can decrease cortisol levels and increase more gray matter in the brain. Mindfulness each day builds psychological resilience, improves emotional regulation, and enhances concentration. 2. Physical activity: Physical exercise is a well-documented stress reducer. Walking, yoga, or weightlifting reduces depression and anxiety and stimulates the production of brain-derived neurotrophic factor (BDNF), a protein that supports healthy brain function. 3. Healthy sleep patterns: Chronic stress can disrupt sleep, which in turn negatively affects cognition. Maintaining a consistent sleep schedule and creating a calming atmosphere are central to brain rejuvenation and stress management.

Balanced nutrition: Dietary consumption of fruit, vegetables, lean protein, and omega-3 fatty acids promotes brain function and stabilizes mood. Curbing the habit of excessive caffeine, sugar, and processed food consumption also stabilizes reactions to stress. 5. Social connection and support: Good support and relationships can act as a buffer to protect against the effects of stress. Talking to friends, going to support groups, or seeing a therapist can provide emotional relief and improve coping skills.

Lifestyle habits that secretly increase inflammation
Lifestyle habits that secretly increase inflammation Credit: Getty Images Chronic inflammation is like a slow-burning fire inside the body, it doesn't cause instant damage, but over time, it can increase your risk for serious conditions like heart disease, diabetes, joint pain, and even cancer. While inflammation is a natural defense mechanism, certain daily habits can keep your body in a constant state of stress. Packaged snacks, sugary drinks, fried items, and fast food are high in refined sugars, trans fats, and additives. These foods disrupt your gut microbiome and trigger the release of inflammatory chemicals in the body. Too Much Processed or Junk Food Sitting for long hours and avoiding exercise increases inflammatory markers like C-reactive protein (CRP). Regular movement helps regulate your immune system and reduce inflammation. Lack of Physical Activity Getting less than 6–7 hours of quality sleep a night can raise stress hormones and inflammation. Studies show sleep deprivation leads to higher levels of cytokines, proteins that promote inflammation in the body. Poor Sleep Patterns Living in a constant state of stress triggers the release of cortisol, your body's primary stress hormone. While short-term stress can be helpful, chronic stress keeps the immune system overactive, leading to inflammation over time. Chronic Stress and Anxiety Tobacco smoke contains chemicals that damage blood vessels and tissues, prompting an inflammatory response. Drinking alcohol in excess disrupts the gut and liver function. Smoking and Alcohol Inflamed gums or untreated dental infections may not seem like a big deal, but they can release pro-inflammatory bacteria into your bloodstream, contributing to systemic inflammation. Ignoring Oral Health Inflammation isn't always visible, but its effects build up over time. Mindful habits can protect your long-term health.

Just a daily walk can help prevent dementia and heart disease
A simple activity like walking has life-saving benefits. If it is done correctly, it can be the key to losing weight, lowering blood pressure and cholesterol, and boosting your memory, as well as reducing your risk for heart disease, diabetes, cancer, and more. With the elderly population projected to reach 19.1% by 2050, the burden is expected to grow significantly. Parallelly, cardiovascular diseases (CVDs) continue to be the leading cause of death. In this context, lifestyle interventions like regular walking emerge as simple, cost-effective strategies to reduce the risks of both dementia and heart disease, especially among older adults in India. Understanding dementia and heart diseases in India According to the study published in the National Library of Medical Science (NLM), in India, dementia affects 7.4% of adults aged 60 and above, with variations based on age, education, gender, and rural or urban residence. Around 8.8 million individuals in this age group are living with dementia, necessitating tailored local planning and support, especially in states and subpopulations with higher prevalence among females and in rural areas. It is forecasted in the study of Changing demography and the challenge of dementia in India that by 2050, it is anticipated that 19.1% of India's population will be aged 60 years and above. Due to its large population, South Asia, particularly India, is expected to be a significant contributor to this rise, although variations may occur based on demographic differences in Kerala and Uttar Pradesh. Importance of walking speed to reduce risk of dementia The assessment of walking activity, conducted using the validated Lifetime Total Physical Activity Questionnaire, reveals that both the intensity and duration of walking play significant roles in influencing cognitive health outcomes. Participants were categorised based on walking frequency, intensity (low, moderate, or vigorous), and the stage of life when walking was initiated (midlife vs. late life). According to NLM research, physical activity is one of the protective and cost-effective practice activities against dementia, and recent studies show that even a single form of physical activity like walking can positively impact brain health. Walking requires no special training, costs nothing, and can be done almost anywhere, making it a practical choice across all ages. Importantly, a slow walking speed has been identified as a major risk factor for developing or worsening Alzheimer's-related symptoms. This implies an inverse relationship between walking and cognitive decline—the more consistently one walks, the lower the risk may be. Several long-term studies support this idea. For instance, older women who walked more frequently showed lower chances of cognitive decline over a period of 6–8 years. Similarly, elderly men who maintained regular walking routines had a significantly reduced risk of developing Alzheimer's dementia. Major findings indicate that individuals who engaged in regular, moderate-to-vigorous walking—especially those walking more than 360 minutes per week—showed a lower risk of Alzheimer's-related cognitive decline compared to non-walkers or those with lower-intensity activity. Notably, the timing of walking initiation also mattered: those who began walking in midlife (ages 40–64) demonstrated stronger cognitive protection than those who started in later life. How walking helps with heart diseases Multiple studies have shown that walking regularly, even for just 20 to 60 minutes a day, a few times a week, can significantly reduce key risk factors linked to heart disease. In a review of 14 walking-based intervention studies published in the National Library of Medical Science (published in 2009–2010), participants followed walking routines lasting anywhere from 3 weeks to 12 months. The results showed consistent improvements in cardiovascular fitness, which is a major factor in preventing heart disease. Participants reported better endurance, easier breathing during activity, and improved ability to exercise. Regular walking at a moderate intensity—the kind that makes you breathe faster, sweat lightly, or feel a bit flushed—was most effective in improving heart strength and blood flow. In some studies, walking even lowered blood pressure, especially in people with mild hypertension or those at risk due to age and other conditions. Other health benefits included: Reduced body fat and weight Improved cholesterol levels Increased distance walked without discomfort in people with circulation problems (like peripheral artery disease) These changes may seem small at first, but over time, they add up to a significant reduction in the risk of heart disease, stroke, and related complications.
