“I hid my weight pretty well but I wasn’t fine, I was super unhappy, miserable and I was working out like an animal with no results,” she wrote.

Ok ignore how absolutely awful I look in these photos 😂 but I wanted to post my progress over a year, now I know people are gonna say you look fine on the photo on the left ( and that’s sweet) I hid my weight pretty well but I wasn’t fine, I was super unhappy, miserable and I was working out like an animal with no results for a couple reasons…1) I had a doctor lie to me and give me hormones I didn’t need which made me gain 40lbs ( this is common as the more they sell the more bonuses they get, like trips to Hawaii!) 2) even though I was working out I ate like shit because I was in a completely unhealthy relationship…I first had my mommy make over with @drleifrogers this was to fix my muscles which was probably the best thing I ever did in my life!! I am so grateful for him and his staff! And if you have had c sections or recti diastassis from babies look into it! My YouTube video on my journey is on my link tree in bio! 3)! I started working with @davidallennutrition who finally got the hormones out of my system and got me eating properly, he custom makes plans to your bloodwork!! It’s epic! I stopped eating for emotional pleasure and started eating to fuel my body. I also started using @bombshell_news workouts and conquered my fear of weights… and finally got out of a relationship that didn’t empower me. There was no easy fix, there was no overnight plan… but i had an awesome team and I now just work out daily, I still eat healthy but allow myself some good stuff and I’ve learned soooo much from the whole experience the last two years! I hear from moms and newly divorced women everyday who are in the thick of things and I wanted to show if I can do it, I know you can too! ❤️👊🏼⚓️💪🏼

She added that part of why her fitness regimen wasn’t working is that “I had a doctor lie to me and give me hormones I didn’t need, which made me gain 40lbs.”

Moakler also explained that she “ate like s**t” due to an unhealthy relationship.

Now she has gotten back on track to lose the weight and get back in shape.
