I have now lost about 20kg in about 2.5 years. Back into size 10's and feeling great. Over the last couple of months I have started doing some personal training (just once a week but using some of her equipment in my own workouts) to try and tone up / get a bit more definition to my body. Its been a long slow process but everything I'm doing is totally sustainable in terms of amount of training, the food I eat and alcohol!! Still doing karate but after last years 4th Dan grading I'm mostly just teaching this year and helping my son prepare for his junior blackbelt.
