All about interval walking training, a Japanese technique to improve heart health, recover post surgery
Author Kashif Khan recently discussed it in an Instagram post, sharing that Japanese researchers developed Interval Walking Training (IWT)—a simple but powerful method that, when done consistently, has been shown to lower blood pressure, reduce depression, and even cut stroke risk by 40 percent.
Here's how it works:
Instead of walking at the same pace, you alternate between:
– Three minutes of slow walking
– Three minutes of fast walking
Keep cycling through this pattern for about 30 minutes.
And the results? 'People who do IWT see 4x more improvement in blood pressure than those who just walk 10,000 steps a day. It also improves muscle strength, boosts the immune system, and enhances sleep efficiency by 12 percent,' informed Khan, adding that it is an easy, free, and incredibly effective way.
Does it work?
Dr Ranjan Shetty, lead consultant, cardiologist SPARSH Hospital Infantry Road and medical director, SPARSH Group of Hospitals said that it significantly improves cardiovascular health by lowering blood pressure and cholesterol, making it particularly beneficial for people at risk of heart disease.
'It also helps regulate blood sugar levels in people with type 2 diabetes and enhances overall physical fitness by increasing muscle strength and aerobic capacity. Moreover, IWT is also linked to reduced depression and better mental well-being. This method is beneficial for those recovering from joint issues or post-surgical rehabilitation, as the variation in pace minimises joint strain while still promoting mobility,' said Dr Shetty.
However, if people have pre-existing conditions, they should consult with an expert before starting. 'It's important to start gradually, wear supportive footwear, and stay hydrated,' said Dr Shetty.

Dr Shetty advised using a fitness tracker to help maintain appropriate intensity levels. 'The way to success with IWT is consistency. Regular practice, ideally several times a week, can yield significant health benefits over time,' said Dr Shetty.

Suffering From Hair Loss? Nutritionist Shares 6 Protein-Rich Foods That Promote Hair Growth
Strong, luscious hair is often a reflection of overall health and wellness. However, factors like poor nutrition, stress, and environmental damage can take a toll on its health, leading to breakage, thinning, and dullness. A well-balanced diet rich in essential nutrients can help promote healthy hair growth and strength. Nutritionist Nmami Agarwal shares six protein-packed foods that can help you achieve the hair you've always wanted. In a post shared on Instagram, Nmami explains the importance of protein in hair health. She writes, "Hair is mostly keratin, a protein built from amino acids. When your body lacks protein, it prioritises essential functions, leaving hair growth on hold. This weakens hair follicles, slowing growth and triggering shedding a few months later. Hair might also become brittle." View this post on Instagram A post shared by Nmami - Dietitian|Nutritionist (@nmamiagarwal) 6 Protein-packed foods you can eat for stronger and healthier hair: 1. Dal (lentils) Affordable and versatile, dal packs a protein punch. The protein content varies depending on the type of dal, but generally falls within a good range for a plant-based food. 2. Paneer (Indian cottage cheese) Enjoy this complete protein source in curries, stir-fries, or grilled. It typically provides 18-25 grams of protein per 100 grams. 3. Sattu Budget-friendly and complete protein, sattu is perfect for breakfast or any meal. It is often considered a source of essential amino acids, including lysine, leucine and valine. 4. Chicken Lean protein with endless cooking options: curries, kebabs, or grilled with veggies. Chicken is considered a complete protein, meaning it contains all nine essential amino acids required for the human diet. 5. Fish Fish provides complete protein and healthy fats, both great for hair. It is vital for building and maintaining muscle mass, repairing tissues and supporting a healthy metabolism. 6. Peas Surprisingly, peas are very high in protein, along with Vitamin K and other minerals. The protein content can vary depending on the type of pea and how it's prepared. Nutritionist Nmami Agarwal recommends eating a balanced diet with these protein sources. You can also add fruits, vegetables, and whole grains to your diet. This ensures your body has everything it needs for healthy hair growth and overall well-being. Disclaimer: This content including advice provides generic information only.

Check out the five everyday symptoms and powerful foods that can help, according to Lovneet, are as follows: Tired after 8 hours of sleep? The nutritionist suggests eating finger millet (ragi), which is 'rich in B-vitamins and iron to fight fatigue'. She also mentions that ragi contains tryptophan, which boosts serotonin and melatonin, helpful for better sleep. Always feel Bloated after every meal? Lovneet suggests eating ginger, which, according to her, boosts gut motility and reduces inflammation. This ultimately helps in bidding adieu to gas and heaviness. Constipated even with fibre? Eat prunes as per the nutritionist as they are 'packed with sorbitol and natural laxatives that gently stimulate the colon'. Feel cold all the time? Lovneet recommends eating sesame seeds, which 'support thyroid health with iron, zinc and tyrosine'. She calls the Sesame Seeds the key to body temperature regulation. Experience brain fog? The nutritionist advises eating walnuts, as they are loaded with omega-3s, polyphenols, and vitamin E, which help sharpen focus and nourish the brain.

Nutritionist says ‘if you eat even a cucumber with a lot of guilt, you will gain weight…'
'Every bite is a gift. When you eat with stress, your body feels it. When you eat with gratitude, your body heals from it. So before your next meal—pause, thank, receive,' says nutritionist Dr Rohini Patil. According to the nutritionist, guilt associated with food can lead to an unhealthy relationship with it. 'If you eat a cucumber with a lot of guilt, you will gain weight. That cucumber is going to do more harm to your body. But if you have a pizza or a burger out of love, gratitude, happiness and a lot of love, that will do more good to your body than one piece of cucumber,' said Dr Patil in an interview with Reema Mahajan on Instagram. Muskan Marwah, a psychologist at Mpower, Aditya Birla Education Trust, shared that eating fried meals, desserts, or breaking dietary restrictions can cause a feeling of guilt – generally manifesting in tension, which interferes with well-being, and can even result in mental distress or harmful food habits. 'Social pressures, body image issues, or the internalised notion that indulgence should be avoided are frequent triggers of this guilt,' she said. According to her, food guilt is largely reinforced by one's diet cycle. It starts with violating a food guideline, like overindulging in a prohibited meal or overeating. 'Feelings of guilt follow, and people start eating less to 'make up' for the excess. But these limitations frequently result in both emotional and physical suffering, which fuels greater cravings, overindulgence, and a return to breaking dietary guidelines. The cycle keeps repeating, resulting in an endless circle of limitation and guilt,' she explained. Marwah suggested the following tips to rewire your mindset and enjoy your meals guilt-free. 1. Practice Mindful Eating: Savor each bite of your food rather than becoming fixated on it. Pay attention to the meal's flavours, textures, and satisfaction. Eating mindfully improves the whole experience and lowers anxiety. 2. Embrace Flexibility: Recognize that one meal or treat does not negate your overall health objectives and that holiday indulgences are a part of the celebration. Instead of concentrating on perfection, consider balance as a whole. 3. Reframe Your Thoughts: Challenge the idea that indulging in foods is something to feel guilty about. Shift from 'I've ruined my progress' to 'It's okay to enjoy myself today and get back on track tomorrow.' 4. Practice Self-Compassion: Be kind to yourself. Rather than labeling yourself as 'weak' or 'out of control,' treat yourself with the same kindness and understanding you would show a friend. Everyone deserves to enjoy food without judgment.
