I cut back on meat a while ago when I was overweight as it helped me lose fat when i switched to mostly fish plus I wanted to watch my saturated fat intake because I have slightly high blood pressure. Since then my 14 year old daughter decided to become vegetarian about a year ago and it just became easier for me not having to cook seperate meals all the time so I started eating a meat free diet too. We still do eat fish as I encouraged my daughter not to give that up too as I didnt think it would be good for her health.
I have never really liked red meat anyway and I find chicken breasts boring really and would much rather have a big slab of fish instead.
Hope that clears it up a little bit......Thanks
