Getting healthy hoping to be able to be cute again :)

My motivation to begin my weightloss journey began with a trip to the mall with my grandma she is a slim size 6 she was able to purchase nice jeans, cute tops and i am a size 24 couldnt find anything that was flattering on me. I end up wearing pj pants mens tshirts and yoga pants. That is my entire wardrobe. I began to gain weight when i got pregnant with my first son. Before that i had a 26 bmi worked out regularly never drank sodas...and i started to pack on the pounds i am a very large build so at my skinniest i weighed 163 and wore a size 8. After my first pregnancy i weighed 278 i lost a little bit of weight and went down to 245 and 2 years later i got pregnant again and with that pregnancy the most i weighed was 303 i lost a little but never got to less than 275 18 months later i got pregnant with my youngest child and the largest i was there was 320 i was mortified at those numbers on the scale. My daughter is now 3 months old and i am so done being over weight i want to be able to take my children to the park and have fun. I am tired of being fatigued from my body fat. I used to drink 3-4-5 32 ounce sodas a day and i have completely cut those out and replaced them with water. I refuse to eat fast food and i dont let myself get really hungry i snack on cheese sticks apples or cuties regularly because i dont want to starve myself and binge eat. It has only been a week but i can tell a difference in my stomach and my love handles and that keeps me going. My first goal is to fit into a pair of under armour sweatpants that i purchased after my son was born not realizing how much bigger i had gotten i have held onto them thinking someday they may fit. Well now i am ready to make it happen!
