Oh dear - the usual nonsense about lower calories - it never did anything good for me - and I was put on low calorie diets again and again so I lost muscle and gained fat then had to fight to regain fitness and even the ability to run or dance again.
Low calorie just made me very very tired and feeble. I have a fresh pink complexion as a rule - low calorie diets made me either white or grey depending on the severity. I am 67 years old now so I think that I know what I'm talking about - carbohydrate makes you fat - eating less of it, not drinking sugary stuff, avoid beers, and you should find that you shrink down quite rapidly once you get going - you'll need to adjust slowly, reducing your insulin as you reduce the carbs.
Check the carb content of food - cabbage and cauliflower are not starchy vegetables by the way - the real heavy weights are bread, pasta, potato, rice, oats - breakfast cereals are usually starch and sugar combined.
I always had so much trouble losing weight, because of all the bad advice about 'healthy' carbohydrates such as fruit - full of sugars!! Once I was settled on the right amount of carbs I lost 2Kg a week - I was in my early 20s then, after trying to diet on low calorie and putting on weight - I was not popular at all.
