I found cutting out carbs worked best for me. I was having a large breakfast (sausage, bacon, egg, black pudding), a Cupasoup at lunch, and then something like a pork chop or chicken breast with roasted vegetables. Wasn't hungry in the least, and I lost a stone over a month or so. Mind you, I was also playing badminton twice a week, too
Ditch the fancy diet fad as it won't be sustainable long term and is too restrictive. If you have a smartphone download the Myfittnesspal app. It's like having a personal trainer and nutritionalist for free and with you 24/7. I lost 17kg in 6 months and have kept it off for 2 years now.
