Prioritising quality sleep

The doctor recommends getting 7-8 hours of sleep, as a poor sleeping schedule not only leaves you tired, but it also disrupts gut bacteria, affects blood sugar control, and increases inflammation. Over time, this can impact overall well-being.

Daily movement and protein intake

Staying active every day, whether through strength training or regular walking, plays a key role in maintaining balance. Alongside regular exercise, adequate protein intake supports muscle health, one of the strongest indicators of long-term fitness and functionality.

Daily fiber intake

A dietary regimen rich in beans, vegetables, berries, and seeds ensures sufficient fiber intake, claims the gastroenterologist. Most people consume only about half of what they actually need, which can affect digestion and disrupt internal balance.

Include fermented foods

Adding fermented foods like yogurt, kefir, kimchi, sauerkraut, and dahi to your everyday meals can support the gut microbiome. These foods naturally contribute to better digestive health and internal harmony.

Limit ultra-processed foods

Occasional indulgences, cheat days, or relishing takeaway foods are not a problem, but you should reduce over–reliance on ultra-processed foods. Focusing on meals made from real, whole ingredients helps create a more sustainable and mindful approach to eating.

Manage stress

Chronic stress is a silent killer, slowing digestion and disrupting the gut-brain connection. Incorporating simple practices like daily meditation can help in lowering stress levels, bringing a sense of balance to both the mind and body.

Stay curious

Dr Saurabh Sethi’s last piece of advice is to keep alive your curiosity and engage in continuous learning to keep the mind active and engaged. Whether through building projects or creating content, staying mentally stimulated adds another dimension to overall well-being.
