Demi Lovato has lauded her trainer for all the help he has done to help overcome her eating disorder and be physically, mentally, and emotionally healthy.

Lovato, a 22-year old singer, has taken this praise to her Instagram account where she posted a four-framed photo showing her diet and work-out notes, motivational Bible verses, mirror quotes and a picture of her sweaty in the gym with her fitness trainer, Ronny Comacho.

"For the past 8 months this man has helped me beat my hardest critic: myself. The first day he gave me my meals, that him and his wife cook themselves, he looked me in the eyes and said 'We are going to kick this eating disorder's a**!!!' He was as determined as I was and has been a huge part of my recovery ever since. I've never been happier and healthier and I credit so much of that to this man and his beautiful wife. Thank you Ronny & Elise Comacho for staying up so late to cook my meals and getting up so early to help transform my body but most importantly my mind," She said on the Instragram caption, "You both have truly changed my life."

Giving back what is due, Lovato boosted Comacho's fitness company 'uevolve.fitness' for his family's efforts to put Demi Lovato back into the right shape in all aspects.

The singer/actress has long been open about her body image issues. She had been in and out of rehab due to this and other disorders which was triggered by her emotional and physical issues.

On her Twitter account she had posted, "Wait.... So you mean to tell me eating healthy and working out works??? You don't even need diet pills??! Who woulda thunk..."

With Lovato currently happy about her recovery, she is even happier with her current relationship to Wilmer Valderrama who has been very supportive to her.
