Like me, if you too have been curious to know more about intermittent fasting (IF) and how it might transform your approach to health and weight loss? Well this popular trend isn't just about what you eat—it's about when you eat. From time-restricted eating to alternate-day fasting, IF offers a variety of approaches tailored to your lifestyle. Emerging studies, including a comprehensive 2019 analysis, highlight its potential to lower BMI, reduce fat mass, and improve metabolic health. Intriguingly, research shows eating earlier in the day can curb appetite and boost fat burning.

With a focus not just on what you eat, but when, IF challenges traditional meal schedules and reshapes our understanding of healthy eating patterns. Backed by evolving science, this approach highlights the impact of timing on our metabolism, energy levels, and even cellular health. Intermittent fasting is not a one-size-fits-all approach, but it offers a promising alternative to traditional dieting.

What Is Intermittent Fasting?

Intermittent fasting isn't a novel concept. Historically, fasting has roots in cultural and religious practices. However, modern IF takes a more structured approach, dividing periods of fasting and eating into deliberate cycles. Popular methods include:

1. Time-Restricted Eating

Eating is limited to a specific window of the day, such as 8 a.m. to 8 p.m., with fasting outside of these hours.

2. Alternate-Day Fasting

Alternating days of normal eating with days of calorie restriction or complete fasting.

3. 5:2 Diet

Eating normally for five days and drastically reducing calorie intake for the other two days.

4. 16:8 Diet

Fasting for 16 hours and eating within an 8-hour window, often aligning meal times with natural daylight hours.

How Does Intermittent Fasting Work?

The fundamental premise of IF is to optimize the body's natural metabolic processes. Prolonged periods of fasting push the body to shift from relying on carbohydrates for energy to burning fat, entering a state called ketosis. This metabolic switch is linked to numerous health benefits, including weight loss and improved cellular repair processes.

According to Johns Hopkins Medicine, IF also aligns with the body’s circadian rhythm—our internal biological clock that influences sleep, digestion, and hormone regulation. Studies suggest that eating in sync with this rhythm, such as having larger meals earlier in the day, can enhance metabolic health and regulate appetite.

Benefits of Intermittent Fasting

Emerging research highlights the promising advantages of intermittent fasting (IF). A 2019 study in the Journal of Clinical Medicine found that IF significantly lowers BMI and fat mass compared to traditional calorie-restricted diets by naturally reducing calorie intake through limited eating hours. Additionally, a 2019 review in The New England Journal of Medicine emphasizes IF’s role in improving metabolic health by reducing belly fat, enhancing insulin sensitivity, and lowering inflammation. A small 2019 study in Obesity revealed that early time-restricted feeding, such as eating between 8 a.m. and 2 p.m., boosts fat oxidation and reduces appetite.

Furthermore, fasting periods trigger autophagy, a cellular repair mechanism that eliminates damaged components, which is associated with increased longevity and a lower risk of chronic diseases.

Risks of Intermittent Fasting

While the benefits of IF are promising, it’s not without challenges or risks. Certain groups should avoid IF or approach it with caution:

  • Prolonged fasting may deprive individuals of essential nutrients, especially if meal quality is poor.
  • Excessive calorie restriction may interfere with menstrual cycles or lower testosterone levels.
  • For individuals with a history of eating disorders, IF might exacerbate unhealthy behaviors.

Common Intermittent Fasting Mistakes To Avoid

To reap the benefits of IF, it’s crucial to avoid these pitfalls:

  • Starting Too Aggressively- Diving into extreme fasting schedules can shock the body and lead to burnout.
  • Inadequate Meal Planning- Eating calorie-dense, nutrient-poor foods during eating windows can sabotage weight loss and health goals.
  • Neglecting Hydration- Fasting periods can dehydrate the body if water intake isn’t prioritized.
  • Unsustainable Schedules- Choosing a plan that doesn’t align with your lifestyle increases the likelihood of quitting.

How to Maximize the Benefits of Intermittent Fasting?

For those ready to incorporate IF into their routine, here are a few tips to ensure success:

  • Eat Balanced Meals: Focus on vegetables, lean proteins, healthy fats, and whole grains during eating windows.
  • Time Your Meals Wisely: Consume larger meals earlier in the day to align with your circadian rhythm.
  • Stay Active: Moderate exercise can complement fasting by enhancing fat burn and improving energy levels.
  • Listen to Your Body: Adjust your fasting plan if you experience fatigue, irritability, or other adverse effects.

As always, consult a healthcare professional before embarking on any new diet regimen, particularly if you have underlying health conditions. After all, the old adage “you are what you eat” is evolving—and now, it’s also about when you eat.

Energy drink is linked with stroke risk was found out when a fit 54-year-old man suffered stroke. Previously Health and Me also reported about the man, a non-smoker and non-drinker, who suffered stroke, thanks to his habit of consuming energy drinks. The doctors found his blood pressure to be sky rocketing. His left side of the body was weak, he lost balance, had trouble walking and speaking.

Another similar case comes from Canada, where a 10-year-old also suffered a seizure, consuming just two energy drinks in the week.

Experts are now weighing in if it is at all safe for anyone to consume energy drink.

Energy Drink: Are They Safe To Consume?

As per the Food and Drug Administration (FDA), energy drinks are "pure and highly concentrated caffeine products can have serious health consequences, including death."

A BMJ study from 2025, Energy drinks, hypertension and stroke, found high morbidity and mortality rates associated with stroke and cardiovascular disease linked to high-sugar drink consumption.

Energy Drink: What Do experts Think Of Its Safety?

Speaking to wmur.com, Dr Raj Dasgupta, a board-certified physical who specializes in internal medicine, pulmonology critical care, and sleep medicine said, "Caffeine is a stimulant, which means it increases activity in your brain and nervous system."

Caffeine keeps us awake by blocking adenosine, the brain chemical responsible for making us feel drowsy. Energy drinks boost alertness and focus partly by increasing adrenaline levels, though how strong the effects feel and how long they last can vary based on the person and the amount of caffeine consumed.

What Makes Energy Drinks Different From Coffee?

The short answer is that it depends. The energy drink market is huge, and there is no one-size-fits-all comparison. That said, many energy drinks do contain more caffeine per serving than a regular cup of coffee.

An average 8-ounce cup of brewed coffee has about 95 to 100 mg of caffeine. Energy drinks, on the other hand, can range widely, often providing anywhere between 70 and 200 mg per serving. The actual impact depends on how much you drink and how your body responds to caffeine.

Where The Caffeine In The Energy Drink Comes From Matters

Not all caffeine is created equal. The source can influence the drink’s overall nutritional value.

Some natural sources, like green tea, come with added benefits such as antioxidants and trace minerals. Ingredients like guarana and yerba mate also contain natural compounds that may support mood and energy levels. In contrast, highly processed or artificial caffeine sources usually do not offer these extra benefits.

The Sugar Problem Of Energy Drinks

One of the biggest differences between coffee and energy drinks is sugar. Coffee can be customized, so you control how much sugar goes in. Many energy drinks, however, are loaded with added sugar.

For example, a single 16-ounce can of some popular energy drinks can contain over 60 grams of sugar, well above the recommended daily limit. Some brands use artificial sweeteners instead, which research has linked to a higher risk of heart disease and stroke over time.

How Safe Are Energy Drinks?

Health experts agree that moderation is key, regardless of your caffeine source. Most healthy adults can safely consume up to 400 mg of caffeine per day.

Too much caffeine can cause shakiness, poor sleep, a racing heartbeat, headaches, or stomach issues. Over time, excessive intake can also lead to dependence, meaning you need more caffeine to feel the same effect.

Who Should Be Extra Careful Before Consuming Energy Drinks?

Certain people should be more cautious with energy drinks. Caffeine can worsen anxiety and interfere with sleep, especially for those already struggling with these issues. People with heart conditions may also need to limit or avoid caffeine since it can raise heart rate and blood pressure.

While labels may highlight antioxidants or added supplements, the high sugar, caffeine, and preservatives often cancel out these benefits. The same nutrients can be found more reliably in whole foods like fruits and vegetables.

Can Ozempic Trigger Nausea After Greasy Meals? Doctor Weighs In

Updated Dec 16, 2025 | 03:00 AM IST

SummaryOzempic can cause nausea after greasy meals by slowing digestion and increasing fullness. A diet expert explains why this happens, which foods trigger symptoms, and when to see a doctor.

As the use of anti-obesity medicines like Ozempic continues to grow, more people are trying to understand what daily life looks like on these injections. Beyond weight loss results, concerns often centre on side effects, especially those linked to digestion. Many users of GLP-1 agonist medicines report gastrointestinal issues such as nausea, vomiting, constipation, and heartburn. In recent months, another pattern has caught attention. Several people say they feel sick after eating greasy or oily food.

To understand why this happens, we spoke to Dr Pratayksha Bhardwaj, World Record Holder Dietician and Weight Management Specialist, who explains that this reaction is more common than people realise.

What Ozempic Does Inside the Body

Ozempic, medically known as semaglutide, was originally developed to help manage Type 2 diabetes. It is now widely prescribed for weight management because of how it influences appetite and digestion.

According to Dr Bhardwaj, Ozempic works by slowing down gastric emptying and acting on appetite-regulating centres in the brain. “Food stays in the stomach longer, and the feeling of fullness comes earlier than usual,” he explains. This change helps people eat less but also alters how the body handles certain foods.

Why Greasy Food Can Trigger Nausea On Ozempic

Fatty and oily foods naturally take longer to digest. When this process is further slowed by Ozempic, the stomach can struggle to cope with heavy meals.

Dr Bhardwaj says that eating large portions, especially foods high in fat, can overwhelm the digestive system. “When fatty foods sit in the stomach for too long, they can trigger nausea, vomiting, or even diarrhoea,” he notes. This is why some people feel unwell shortly after eating fried snacks, fast food, or rich gravied dishes.

Is This an Allergy or Something Else?

Many patients worry that vomiting after eating greasy food might be a sign of an allergic reaction. Dr Bhardwaj clarifies that this is not the case. “This response is physiological, not allergic,” he says. It reflects how the body adapts to the medication rather than an intolerance to the drug itself.

Clinically, doctors observe that tolerance for oily foods drops sharply after starting Ozempic. Vomiting is more commonly reported during the early stages of treatment or when the dose is being gradually increased.

Can This Side Effect Be Beneficial?

Interestingly, this reaction can support healthier eating habits. Dr Bhardwaj points out that the discomfort acts as a natural reminder to change food choices. Patients are often advised to eat smaller portions, reduce fat intake, and include more fibre-rich vegetables in their meals.

Lower-fat foods are easier to digest and less likely to cause nausea. Over time, many people find that their preferences shift away from heavy, greasy meals.

When to Seek Medical Advice?

While occasional nausea can be expected, persistent vomiting should not be ignored. Dr Bhardwaj advises consulting a doctor if symptoms continue. In some cases, a dose adjustment or personalised nutrition plan may be needed to reduce discomfort while continuing treatment safely.

Ozempic can be effective, but understanding how it interacts with food is key to managing side effects and maintaining long-term health.

Updated Dec 15, 2025 | 01:36 PM IST

SummaryDuring his India visit, Lionel Messi’s fitness has sparked curiosity, his diet shift. Once known for pizzas and sugary foods, he adopted a simple, controlled eating plan in 2014. Built around water, olive oil, whole grains, fruits and vegetables, the diet reduced inflammation, improved recovery, and helped sustain performance at 38.

Lionel Messi is here in India and is ready for his touch down in Delhi on December 15 as part of his GOAT (Greatest of All Time) Tour's India visit. Argentina's World Cup-winning captain is also set to visit Hyderabad after his visit in Delhi, for now, he has met his fans in Mumbai and Kolkata. All things said and done, what every one is always curious about is a sports person's fitness regime. The 38-year-old football star undergoes a strict fitness regime, which includes consistency, but it is not based on heavy lifting, but agility training, and a simple not-too-fancy diet.

However, his fitness journey was not traditional in any manner. In fact, during his early years, he was known for eating without much of a thought. So, what changed him? What is his secret to a fit life?

How Messi Changed His Eating Habits To Stay Fit

In 2013-14 World Cup, which was disappointing for Messi, ESPN India reported that Messi improved his performance by adapting a new diet. Charly Rexach, the then FC Barcelona's sporting director, who signed the then 13-year-old Messi to the club in 2000 on a napkin, said that Messi had previously "eaten too many pizzas".

In an interview to America TV's La Cornisa, Messi admitted about his eating habits and poor diet, which had even led to bouts of vomiting, nausea, and even lethargy. The footballer said, "I don't know what I ate, but I ate badly for many years. At 22, 23...[it was] chocolate, alfajores [South American sandwich cookies], fizzy drinks."

It was nutritionist Giuliano Poser who helped Messi make changes in 2014. His diet was nothing fancy, nothing too difficult, but it was controlled.

Five Pillars Of Messi's New Diet

Messi's new diet was based on five pillars:

  • Water
  • Olive oil
  • Whole grains
  • Fruits
  • Vegetables

Messi also shared in an interview, "Now I eat well: fish, meat, vegetables, salads. Everything is organized and taken care of. Sometimes a bit of wine, but that's not a problem."

This diet helped him reduce inflammation and recover his muscles faster. When it came to avoiding certain foods Poser stressed the importance of eating little sugar and refined flour. Poser called these two "the worst thing for the muscles". "The farther he stays away from sugars, the better. Refined flours are also a big problem as these days, it’s difficult to find uncontaminated wheat.”

Water

Studies published in the Journal of Athletic Training and Journal of Physical Therapy Science, show that dehydration increases markers of muscle damage and inflammation after exercise. Research also notes that adequate hydration supports blood flow and nutrient delivery, which are essential for muscle repair.

Olive oil

Research in Nature and the Journal of Nutritional Biochemistry highlights that extra virgin olive oil contains oleocanthal and polyphenols, compounds shown to have anti-inflammatory effects similar to mild anti-inflammatory drugs, helping reduce muscle soreness and inflammation.

Whole grains

According to studies in the American Journal of Clinical Nutrition, whole-grain intake is associated with lower levels of C-reactive protein, a key marker of inflammation. Their complex carbohydrates and magnesium content support muscle function and recovery after physical activity.

Fruits

Research published in Nutrients and Sports Medicine shows that antioxidant-rich fruits like berries and citrus help reduce oxidative stress caused by exercise, which can otherwise delay muscle recovery and increase inflammation.

Vegetables

Large observational studies, including reports in The BMJ, link high vegetable intake with reduced systemic inflammation. Their vitamins, minerals, and phytochemicals support immune response and tissue repair, aiding post-exercise muscle recovery.

What Does Messi's Workout Regime Look Like? 3s Of Messi's Fitness

As per reports, Messi's training is not as rigorous as players like Neymar and Cristiano Ronaldo, but it does not mean that there is not consistency. In fact, his primary training focuses on three factors:

  • Speed
  • Strength
  • Stretching

The footballer’s fitness does not come from heavy weightlifting. Instead, it is built on a balanced routine that focuses on strength training, agility, speed, extensive stretching, and overall muscle health. His workouts include short, explosive sprints, bounding drills like hurdle hops and pillar skips, all aimed at keeping his body sharp, responsive, and match-ready.
