Jenn,
Everyone has given you excellent advice.
In the beginning I had to literally remove my scale. I was becoming obsessed with the numbers, which is not healthy (or it was not for me).
Short story, I lost a lot of weight, inches, and gained muscle over a long period of time. I am a mom to three boys (I gained a lot of pregnancy weight and spent 5 months on hospital bedrest with the twins' pregnancy). I shed 70 pounds, 67 1/4" overall, and my body fat is normal and healthy.
My resting heart rate (not waking, just sitting) is 50 and my BP is low.
I did it all through lifestyle change, hard work (I workout daily at home, I am not a gym person) and patience. And yes, I still eat desserts.
Our bodies fluctuate all the time. You mention following the advice of your bodybuilding father? Are you trying to build muscle? Lean muscle? Fat loss? All of the above?
What works for one person may not work for the next person. Also, as you most likely know our bodies rapidly get accustom to a program we we occassionally need to shake things up.
In the end, I trust my measurements and overall how I look and feel.
Take the regime you were given, then tailor it to fit your body's needs.
Just my opinion, take it for whatever it is or is not worth.
Be kind to yourself, have patience, and you will get to where you want to be.
Jennifer
