I Have a 1.5 Finger Width Diastasis Recti and an Outie Belly Button? (photo)

Thank you for your question and pictures. Unfortunately, exercise alone will not address the facial diastases that you have. You are a good candidates to undergo a mini abdominoplasty and fascial plication during which you umbilical hernia repair will be addressed. This will in turn give you an "inny" after the operation. Best of luck.

It appears that your main problem is diastasis of the rectus muscle and not really your weight.  Even when you reach your goal weight you will still have the diastasis regardless of how much you exercise.  Also your "outie" belly button is likely an umbilical hernia.  All of these issues need to be evaluated by board certified plastic surgeon.  You likely would be a good candidate for an excellent result from a tummy tuck procedure.
