Amidst the constant stream of diet trends, it's really important to prioritize health over quick fixes. Many people will follow diet trends they find on social media and follow it, ignoring how it may affect their health later in life. While eliminating sugary drinks and processed foods can be beneficial, you must remember that you are cutting out a big chunk of macronutrient groups, which can lead to nutritional deficiencies and health problems. Then we have the carnivore diet, an extreme version of the ketogenic diet, which eliminates carbohydrates entirely, relying solely on animal products for sustenance. This approach raises significant concerns regarding heart health.

Dangers of Zero Carbs

Having a carnivore diet means complete elimination of carbohydrates, even the ones that have proven health benefits. Many animal products consumed on this diet are high in saturated fat and cholesterol and eliminating plant-based foods which are the primary source of fiber, you are hindering the body's ability to regulate cholesterol and blood pressure. This lack of fiber can also negatively impact gut health, which has broader implications for overall well-being.

Increased Risk of Cardiovascular Issues

We all know that high blood pressure, high cholesterol, diabetes, and obesity are known risk factors for heart disease. While the carnivore diet's restriction of sugar and refined carbohydrates may initially prevent blood sugar spikes, the potential for increased saturated fat and cholesterol intake poses a significant threat. Studies show that increased consumption of red meat and poultry can elevate the risk of high blood pressure in people. Similarly, diets high in saturated fat can raise LDL cholesterol levels, further increasing the risk of heart disease. Therefore, the carnivore diet, while potentially leading to short-term weight loss, may significantly compromise long-term cardiovascular health.

Protecting Your Heart Through Dietary Choices

Maintaining heart health doesn't necessitate eliminating meat entirely, but it does require mindful consumption of saturated fat, you must remember that indulging once in a while does not mean you are no longer taking care of yourself, but the end must justify the process, so try eating a controlled amount. Health organizations recommend limiting saturated fat intake to a small percentage of daily calories. This basically translates to a relatively small amount for most individuals.

Beyond Saturated Fat: Other Dietary Considerations

While saturated fat is a cause of concern, there are other dietary factors that play a crucial role in heart health. Added sugar and sodium can also negatively impact cardiovascular well-being, doctors often discourage people from consuming too much of both as they aid in unhealthy weight gain or high blood pressure. Limiting added sugar intake to a small percentage of daily calories is recommended. Similarly, reducing sodium consumption by substituting processed foods with natural alternatives can contribute significantly to heart health.

Embracing a Heart-Healthy Lifestyle

From the research and studies, we understand that having a more balanced diet, which includes fiber-rich foods like nuts, fruits, vegetables, and whole grains is essential for maintaining heart health. Try aiming for a daily intake of at least 30 grams of fiber and you will see how it can significantly benefit cardiovascular function. Another thing that is equally important is incorporating regular physical activity. Finding enjoyable forms of movement, whether it is a social sports or activities you find pleasurable like dancing, can make exercise a sustainable and positive part of a heart-healthy lifestyle, people often find that dragging yourself to places you do not like does not work long term. With this holistic approach of combining a balanced diet with regular exercise, you will get the best protection for long-term cardiovascular well-being.

New Delhi: The sattvic diet traces back to its roots in ancient Ayurvedic knowledge and is based on the philosophy of Sattva, which stands for harmony, balance, and purity. It places a focus on whole, fresh, and minimally processed meals that support both physical and mental vigour. This "yoga of eating" becomes a biological requirement for preserving homeostasis in the intense summer heat.

Dr. Narendra K. Shetty, Chief Wellness Officer, Kshemavana Naturopathy and Yoga Center, Bengaluru, in an interview with Health and Me, spoke about the science behind following a sattvic diet in summer.

Core principles of sattvic foods

In sattvic diets, foods that are rich in prana (life-force energy), such as seasonal fruits and vegetables, grains, nuts, and seeds, take precedence. "Tamasic" (heavy) foods such as meat and processed sugars should be avoided, as they can weigh the body down and dull the mind. "Rajasic" (stimulating) foods such as caffeine and chili are also avoided.

Scientific basis of nutrition and digestion in summer

According to science, the body's internal thermostat works harder in the summer. Agni (digestive fire) naturally decreases in high ambient temperatures. In order to promote cooling through perspiration, blood flow is frequently redirected from the digestive tract towards the skin's surface. The body struggles to break down dense nutrients with decreased enzymatic efficiency when complex, heavy proteins are consumed during this period, leading to metabolic stress.

Summer physiology: Why light eating matters

A shift towards thermoregulation is required during summer. Heavy meals cause diet-induced thermogenesis, in which heat is produced internally during digestion. By consuming "light" foods, we lower this internal heat load. Because sattvic meals are high in fibre and water, they require less energy to digest, allowing the body to focus on staying cool rather than working on digestion.

Sattvic diet benefits in hot weather

  1. Hydration: Electrolyte balance is maintained due to naturally high water content.
  2. Energy: Provides a steady release of glucose without the "crash" caused by heavy fats.
  3. Mental calm: Reduces agitation and fatigue brought on by heat.

Key sattvic foods for summer

To remain "bright," one should focus on the following:

  1. Cooling fruits like grapes, watermelon, and muskmelon
  2. Hydrating vegetables like cucumber, zucchini, and bottle gourd
  3. Herbs and dairy: fresh buttermilk (chaas), coriander, and mint

Eating light is not just a lifestyle choice but a scientific response to our biological needs. By adopting a sattvic perspective, we ensure that we not only survive but also thrive in the heat by aligning our internal environment with the external season.

The Science Behind A Sweet Tooth: Here's Why You Crave Dessert After Every Meal

Updated Mar 26, 2026 | 09:00 PM IST

SummaryNutrition is the most important component of a healthy life. But for people who have a sweet tooth, it is the deficiency of a major macronutrient, which is imperative for weight management, heart health, and even for keeping diabetes risk at bay.

New Delhi: Many people have an irresistible urge to eat something sweet right after a meal. Although this habit is often written off as a preference or some sort of cultural habit, new scientific data suggest that post-meal sugar cravings hint at something serious: a metabolic imbalance. In an interaction with Health and Me, Dr. Aravind Badiger, technical director, BDR Pharmaceuticals, decoded the intricate science behind a sweet tooth, and as per the expert, it is because of a nutrient deficiency.

The Blood Sugar–Insulin Connection

Upon eating a meal high in carbohydrates, blood glucose levels rise. This triggers the release of insulin from the pancreas. If the meal is low in protein and fibre, insulin spikes more quickly, making the blood sugar drop sooner. This drop then triggers a signal to the brain that the body needs quick fuel, often interpreted as a desire for something sweet. This cycle, a rapid rise and fall in blood glucose levels, is known as reactive hypoglycaemia, one of the common reasons people feel the need to have dessert after meals.

The Missing Nutrient: Protein

Protein helps to regulate blood sugar levels after a meal. In addition, adequate protein:

  1. Slows digestion and glucose absorption
  2. Reduces insulin spikes
  3. Improves satiety by elevating GLP-1 and peptide
  4. Modulates hunger signals via the hypothalamus

    When a meal is low in protein, the body does not get those satisfying signals it is used to receiving. This drives the brain to find sources of energy that work quickly—sugars. In fact, clinical nutrition studies indicate that balanced meals containing at least 20–30 grams of protein reduce post-meal sugar cravings significantly.

    The Gut–Brain Axis Influence

    Your gut microbiome also plays an important role. Meals high in simple carbohydrates encourage the growth of gut bacteria that thrive on sugar. Evidence shows that low-protein diets shift the balance of gut microbes, which further increases sweet cravings. Thus, the less protein you consume, the more your microbiome may “push” you towards sugary foods.

    Emotional and Behavioural Factors

    For some people, dessert cravings are psychologically conditioned. The body learns over time to attach a reward to the end of a meal by releasing small amounts of dopamine. But even in such cases, stabilisation of blood sugar through adequate protein intake reduces the emotional component of cravings.

    How to Reduce Sugar Cravings After Meals

    1. Include 20–30 g of protein in each meal, including eggs, dal, legumes, tofu, fish, lean meats, and dairy products.
    2. Choose complex carbohydrates over refined sugars.
    3. Add vegetables high in fibre to delay the absorption of glucose.
    4. Drink plenty of water – mild dehydration produces symptoms similar to sugar cravings.
    5. Sleep 7–8 hours; sleep deprivation increases the hunger hormone ghrelin.
    6. Do not conclude every meal with sugar. It is a conditioned response and needs to be broken gradually.

    Smartphone Overuse Linked To Rising Risk Of Eating Disorders Among Youth, Study Finds

    Updated Mar 25, 2026 | 12:00 AM IST

    SummaryA study in the Journal of Medical Internet Research links problematic smartphone use among youth to higher risks of disordered eating, body image issues, and mental health concerns, especially with usage exceeding seven hours daily.

    A growing body of research is raising fresh concerns about how deeply smartphones are shaping not just attention spans, but also eating habits and self-image among young people. A recent study published in the Journal of Medical Internet Research has found that excessive and compulsive smartphone use may significantly increase the risk of disordered eating behaviors in adolescents and young adults.

    Smartphones Could Turn Into Dependency

    The study centers on what researchers describe as Problematic Smartphone Use, or PSU. This is not simply spending long hours on a device, but a pattern marked by psychological dependence, difficulty cutting back, and anxiety when separated from the phone. Unlike casual or necessary screen time, PSU begins to interfere with daily functioning and emotional well-being.

    To understand the scale of the issue, researchers analyzed 35 studies involving more than 52,000 participants, with an average age of 17. The findings paint a worrying picture. Young individuals who showed signs of smartphone dependency were more likely to engage in unhealthy eating behaviors. These included emotional overeating, uncontrolled food consumption, and patterns resembling food addiction, even in the absence of a formal diagnosis.

    A 7-hour Tipping Point

    One of the most striking findings of the study is the identification of a potential threshold. The risk of disordered eating rose significantly among those who used their smartphones for more than seven hours a day. While this may not seem unusual in an increasingly digital world, the study suggests that crossing this limit could have tangible effects on both mental and physical health.

    A key factor driving this link appears to be body image dissatisfaction. Constant exposure to curated and often unrealistic images on social media platforms can distort perceptions of beauty and self-worth. Over time, this can lead to unhealthy comparisons and a strained relationship with food.

    More Than Screen Time

    Importantly, the researchers highlight that not all screen time carries the same risk. The distinction between general use and PSU is crucial. It is the compulsive nature of usage, accompanied by withdrawal symptoms and loss of control, that is most strongly associated with negative outcomes.

    The study does not claim that smartphones directly cause eating disorders. Instead, they act as a contributing factor that can amplify existing vulnerabilities, particularly in impressionable age groups.

    Wider Mental Health Implications

    Beyond eating behaviors, excessive smartphone use has also been linked to anxiety, depression, lower physical activity levels, and reduced productivity. These interconnected issues suggest that digital habits are playing a broader role in shaping overall health.

    What Could Help?

    Experts suggest that small, consistent changes can make a difference. Setting clear boundaries for screen time, taking regular breaks, and engaging in offline activities such as sports or hobbies can help restore balance. Encouraging mindful use of technology, especially among younger users, is increasingly being seen as an important step in both prevention and intervention.

    As smartphones continue to be an inseparable part of daily life, the study highlights the need to look beyond convenience and consider their deeper psychological impact.
