For weight loss, boiled chana is generally considered a better option than sweet corn chaat. Boiled chana offers more protein and significantly higher fiber, promoting longer fullness and slower digestion. It also has a lower glycemic index, leading to steadier blood sugar levels. Sweet corn, while providing quick energy and vitamins, is higher in natural sugars and can lead to quicker blood sugar spikes. Its fiber content is moderate, and added ingredients in chaat can increase calorie count, potentially hindering weight loss goals.
