Body fat testing machine

Today I used a body fat testing machine at the gym that looks like this. This girl at the front desk had been telling be about it but I had never heard of it before. Today I asked if I could use it. You have to be there the same time that a personal trainer is there because its in his office. Anyways this guy at the front desk weighed me on the scale at 188.5 ( that was with my clothes and my shoes on in the middle of the day). He entered that into the machine + my age. Then he told me to hold this machine in front of me and press on the handles of it until my results popped up. It says that I have 132.2 pounds of lean mass and that I have 30.2 % body fat. I was wondering what a healthy body fat percentage is for me. I found this on about.com...

What is a Healthy Body Fat Percentage?

Age-Adjusted Body Fat Charts for Men and Women If you look around the Internet, you will see a lot of different recommendations for body fat percentages. As far as I can tell, this is the most authoritative, as it is based on World Health Organization and National Institutes of Health recommendations, and takes age into account. Please do not confuse these numbers with the BMI (Body Mass Index) scores, which are not the same thing.

According to this I am in a healthy range but other websites give different numbers. All I know is that I'm going to keep going until I reach my goal weight. I thought that it was really interesting. When I get to my goal weight I will ask to use it again to see my progress. He also sat down with me and said that based on my lean body mass that I need to eat 78-108 grams of protein MINIMUM. That seems like a lot! He also told me that I need to stop doing the same exercises and weight lifting routines because my body will get used to it and then I will hit a wall. When I told him " Hey I have been doing this for 9 months and I'm still getting the results I want" He was like " Yeah but you could be getting them faster if you had a personal trainer telling you how to do it differently". All I know is that I really am into my routine right now and I can't afford a personal trainer. I feel like I'm just ranting at this point. Lol. I just get so annoyed when people tell me I need to lose weight in a different way because I like how I'm doing it now.
