During fasting, there might be an issue of dehydration. So, always keep in mind that the fluid level in our body should be good enough to sustain and continue the fast.
In my home, we do fasting but make sure to eat well and drink more. We always opt healthy vrat drinks over eatables. Here is our favourite healthy drink which keeps the tummy full.
Nutty Banana Lassi
You can also have it chilled. Yogurt and banana keeps tummy full, and maintains fluid level.
