As someone who went from seventeen and a half stone to twelve in one year I have a bit of experience in losing weight but not body building which seems to be more of what you're doing, which is good as muscles burn more calories. Anyway my advice for losing weight is to always have some water with you and as soon as you feel hungry/thirsty have a sip. it helps a lot as you cut out so much due to getting rid of fizzy and juice drinks which have a lot of sugar. On top of that for me I found that I had an issue with the sensation of putting something in my mouth chewing and swallowing and this helped.
Another thing that is worth goggling is a calorie is not a calorie, it generally says that those with higher fatty diets are hungrier and eat more than those on heavy carbohydrate diets, and those diets will make you hungrier than a protein heavy diet.
What I believe helped me continue or at least never stop permanently was seeing improvements. In the first few weeks I pushed myself hard, probably too hard, but I saw results which showed me that I could do it, most resolution like yours last a little while and people see no chance for all that work and go screw it why bother.
It would be useful for us to know how much time you have to exercise, and whether you feel comfortable being in front of other people, as exercising in your own home can be a bit limiting. for me going jogging at that weight was embarrassing to say the least, but I got around that because I had lots of free time to walk, a lot until I could jog past my street.
