Don't drink anything except water, full fat milk, unsweetened tea/herb tea/coffee. You can have a couple of units of dry wine/cider at the weekend.
Cut out all fructose (remember table sugar ie sucrose is 50% fructose). Fructose = human lard. Fine if you stuff your face with autumnal fruit then hibernate for the winter. Catastrophic for your long term health (& waistline) if your year round hunter-gathering grounds are the snack aisles of the supermarket. So fruit juice, honey, agave, dried fruit, fizzy pop, flavoured yoghurts, sauces, most breakfast cereals, most processed food etc is out. Fresh fruit is fine to eat as it contains fibre which significantly slows down the absorbtion of fructose. Your body has no satiety signal for fructose, which is why you can eat your own body weight in haribo, but not crackers.
Eat full fat versions of things... milk, cream, cheese, greek yoghurt etc. Low fat food has a higher ratio of carbs which will spike your insulin, leading you to lay those carbs down as fat, and also increase your ghrelin which is the hormone telling your brain you are growling hungry. Don't fear the butter :-)
Eat less carbohydrate and put more protein/fat/vegetables on your plate.
Eat high fibre food like brown rice, vegetables, fruit, proper porridge oats.
Fill half your dinner plate with lightly cooked vegetables esp greens, or raw salad.
Don't count calories, they are meaningless on their own. 100 calories of bacon will be metabolised completely differently from 100 calories of fudge cookies.
Eat until you are 90% full but no more. Eat slowly. Focus only on your food and human company at the table... no screens, magazines, radio etc.
Exercise is good, not because it burns calories... that's not significant, but because it greatly improves your insulin sensitivity. Insulin is an anabolic hormone that tells your body to lay down fat. So if your pancreas is able to pump out less insulin in response to one scoop of rice, then you'll be laying down much less belly fat.
Do a hobby in the evening that requires clean hands, like crochet, so you don't snack on greasy/sticky nibbles.
Watch Sugar the Bitter Truth on Youtube, or read books by David Gillespie - Sweet Poison, Robert Lustig - Fat Chance, Gary Taubes - The Case Against Sugar. The latter two have had many articles/reviews in the press recently eg Guardian/NYTimes to read.
