I NEED TO WIN THIS WEIGHT LOST CONTEST

Hi guys!!

My mom, sister, and I are having a weight lost competition to see who can lose the most weight by December 1st!! I need to win because my whole entire family is pretty much doubting me and saying that I won’t take it serious and I really want to prove them wrong. I weigh in at 239.5 and I just wanted to know if anyone has any tips and/or tricks for someone who’s not really that active!! Any advice or encouragement is appreciated!! Thank you so much!!
