Heroines, especially, South Indian lead actresses have to keep themselves lean, these days, hence they don't really project themselves as foodies.
If they do so, they will be termed as fat and unhealthily chubby. They can't really escape the harsh diet regime as desirability becomes highly important.
Still, several actresses express their desire for heavy calorie food items like sweets, ice creams and biriyani(s).
There is a popular song in Mayabazaar, old classic, Vivaha Bhojanambu vinthaina vantakambu, in that we see SVR growing huge to eat all the food items and then reducing himself to normal size.
If you see this picture, Kajal must also be deep inside, praying for such powers to be able to eat the mountain of jilebis in front of her in a jiffy and not grow even 1% fat!
