Stomach increased obesity?

i am 23 yrs old got married 3 months back but now i see my all pants are coming very tight as my stomach size is increased like anything. pls suggest diet plan and excercise I am vegeterian.

www.weightwatchers.com they have plans for vegetarian including vegan..Its a lifestyle and easy to follow

Well sense you are a vegetarian you need to stop eating so much, sense your diet is probably already healthy...Unless you are eating things like Boca Burgers and any Boca type products....they are full of fat and carbs, even without meat they are not that good for you...
A light cardio workout 30 min a day 3 times a week should help you fit back into your pants....it will only take about 3 week to drop about 10 LBS
u are very young so u should not have too much problem getting rid of the extra weight that u have put on. best way would be to do some regular exercises like walking, swimming or some out-door games.

You put on what many people called "married weight"
Where you and hubby eat all the time together, where before you had more discipline.

Keep a journal of what you eat.
And see how your patterns may have changed.

Then maybe its time you start exercising.
They have a surgery where they shrink your stomach. You can lose a lot of weight.
