Hi there, well first off all two stone is not that much to have to loose, so at least you have only two stone to get to your health happy weight. Its fantastic that you are going to do this and you will achieve it. Walking is fantastic, even an hour of walking a day is great. Aim for at least an hour and any more than that later on throughout the day is great. Drinking lots of water up to two litres a day is good, if your not used to drinking a lot of water then if you drink say only two glasses a day then gradually up it to 4 then a week later add another glass until you are at a comfortable level of around 1.5 litres to 2 litres a day. dont drink it all at once this must be spread over the day, two glasses is a must in the morning and two at night. Water is great it will stop you being hungry we often eat when we are actually needing water and not food. Make sure you have breakfast even if its something small its better than nothing. Dont eat at least two hours before bed as it helps digestion and stops you retaining fat, as long as you dont have some kind of health problem in which you have to eat for your blood sugar or something. enjoy your food have smaller portions and have a treat each week too. Give it two months and you will feel the difference, and aim to 4 to 6 months for the weight to be off. remember to maintain it when you have lost the weight. Dancing and zumba is also good for loosing weight if you enjoy it and are able to do it. In the meantime do things that make you happy, if you snack in front of the telly put some carrot sticks etc so your not eating junk. The water will start making you feel less hungry within a week. Good luck
