Losing to gain!

Living in Dubai has its perks, eating out is definitely one of them however I have fallen into the weight gain trap and added about 10kg since relocating. I need to lose this and more to be healthy for me but most of all for my family especially my kids. I have tried every diet over the years and did exercise a lot in Spain before i had a family but at that time there was no incentive other than boredom. Now ill be benefitting me, my family and also a good cause all at the same time.
