I love eating crisps, bread and carbs! I want to replace it for healthy food.

I know the feeling. I used to love crisps, chips, bread and beer (well I still do), but my weight ballooned to dangerous proportions - a BMI well over 40 - that I just had to do something about it; rather than buy yet another larger size set of clothes because all the previous ones were too tight. I'm not sure that I eat helthy food, but I concentrate on protein because that fills me up for longer than carbs and so I can survive between meals. Yes my brain craves carbs, and I have dreams of eating bowls of rice and spaghetti - but I went through all this when giving up smoking many years ago, so I can force myself to get through it.

You need to set up your daily calorie limit; and then look up crisps and bread, etc., on the database. For instance one bag of Tyrrells Furrows, one of my favourites is 714 calories. Just one supermarket garlic baguette is another 705 calories.

Spend as long as you like trying to find food you like, and then try to replace your fat-laden carbs with those. For instance, a large boiled egg is 100 calories, and a couple of grilled bacon rashers are 110 cals. So you could eat two eggs and two rashers of bacon and that would only be half the calories of a garlic baguette.

The problem is that food companies make vast profits on products laced with fat, sugar and other carbs, plus they add cheap salt to make it have a stronger taste, so we are bombarded with adverts for those in order to boost their bottom lines.

I can promise you it will not be easy, and you may have days when you crack - but with a decent amount of willpower and support from people who are going through the same agonies, you ought to be able to get a grip on your eating habits and make steady progress.
