While reading this, I thought of one of my cousins who put to birth about a year ago. For some reasons, her body had grown twice as big and has refused to get any lesser.

Then we have another friend who gains weight just by breathing air. She rarely eats much but her flesh adds up every passing day. We tease her about it though (can't help it sometimes) while the skinny ones just wish they can borrow some pounds from her.

Truth is, hormones play a role in increasing our body size as well. But our lifestyle determine our body mass and weight.

Exercising would keeps the body in shape like you suggested. All the best in your weight goal journey.
