Newbie with a long way to go

So I am a new here. I have never tried my fitness pal before as I have been very loyal to Weight Watchers as their plan has worked for me over the years. My problem is the expense of it all. Each time I was getting into good patterns, my finances meant my membership had to be cancelled.

My last attempt ended a two months ago and shockingly, I've already regained most of the weight I had lost. It was recommended I give this a go instead of struggling to afford Weight Watchers membership.

I am almost 6st overweight and really need to lose this due to hereditary health issues which doctors are convinced I have inherited. I am showing early signs so need to act now to prevent or delay their onset.

So my goal is to slim down healthily while not allowing my food bills to get larger due to my strict household budget and chatting to some like minded people along the way to shifting this weight.
