Largely the same boat.
Was 16st at Xmas, now 15st, portion control, and changing the carbs protein balance has done it for me so far. Hoping to end up close to 12st by the end of the year.
Also think about cross training, I have started to run as well as cycle, mix it up and get your body doing new things, keep it ‘confused’.
Don’t cut your portions too low, that is counter productive, and expect to hit plateau periods where your weight stays the same, you just need to stick with it and the weight loss will start again. Try keeping a diary of your key measurements, some weeks your measurements will reduce but your weight will stay static – Muscle weighs more than fat.
Also don’t weigh yourself daily; I have quickly learned this will drive you mad.
