I need to lose weight

My problem is temptation ! Sweets!! And when I go out to eat with family and friends . Any successful weight loss stories? I’m 50 pounds over weight ( 5’7” 190) im tall with hips but it’s like the weight goes to my arms and stomach . After having a baby recently , I have to do something because I just don’t feel beautiful when I look in the mirror. I’m even thinking about going vegan . But please any tips or help will be appreciated .
