Melissa Joan Hart has lost 29 pounds since January but hopes to lose 30 more.
Melissa Joan Hart is half way towards her weight loss goal.
The 'Melissa & Joey' star - who gave birth to her third child, Tucker, in September and has two other sons, Mason, seven, and Brady, five, with her husband Mark Wilkerson - gained 60 pounds during her last pregnancy and has lost 29 pounds since making a few lifestyle changes in January.
The blonde actress told People.com: ''I was 30 when I had my first child and now I'm 37, so each time it gets more difficult to take the baby weight off.
''My metabolism has changed so it's tricky.''
The former 'Sabrina The Teenage Witch' star credits her husband for helping her make time to attend regular yoga or spinning classes with friends and is thrilled with her results so far.
She said: ''I'm totally satisfied and I'm on a great path. Being a mom made me stop being so hard on myself. My priorities are my children.''
But the actress is especially eager to drop down to her pre-baby weight after signing up to be a spokesperson for weight-loss plan Nutrisystem.
She explained: ''The program is really easy. It's a real help right now in my busy, busy life with my three boys. I don't have to think too hard about it. It's done for me. I just get to enjoy my meal.''
