A carb heavy Indian diet is not automatically unhealthy. The issue is often missing fibre around the carbs.
Rice, roti, poha, upma, dosa, idli and potatoes are common because they are affordable, familiar and satisfying. But when these foods are eaten with little dal, few vegetables and no fruit, the meal can become low in dietary fibre. That changes how filling the meal feels and how quickly hunger returns.
Fibre adds structure to carbohydrate meals. Rice with dal, rajma, sabzi and salad is different from rice with only potato. Roti with chana and vegetables is different from roti with pickle. Whole fruit is different from juice. These changes may support a steadier post-meal experience, though people with diabetes should follow professional advice.
Soluble fibre is often discussed in relation to meal response because some types become viscous in the gut. Psyllium husk is one example. But food should come first: dal, beans, vegetables, oats, millets, seeds and fruit.
Do not fear carbs blindly. Improve the plate around them.
In Indian eating, fibre is the balancing partner that makes familiar carbohydrate meals more complete.
