The are three types of food in this world...

Forget the five food groups, learn these three new groups if you'd rather send the needle on the scales west.

Group 1: Foodstuffs that should never have low-fat versions....
Chocolate Typically chocolate is made low-fat by taking out the stuff that's good for you (antioxidant-rich cocoa) and adding truckloads of sugar to make it taste less like the sole of your shoe. Stick to the best, most rich chocolate you can find and have just a little bit of it.*
Chips Amusingly chip (crisp) packets now advertise '25% less saturated FAT!' This inspires hilarity because they're still mega high in fat, and 75% of the saturated fat still lives in the crunchy, salty grooves of each chip. Of course plain popcorn and pita crisps are lower lipid options, and there is some variance in even the full-fat varieties (crinkle cut v straight cut, Kettle v Smiths etc) but if you're going to salt it up, don't expect to lose weight but eat the real thing because the the low-fat versions taste like crap.

Group 2: Things we eat which are SOMETIMES ok low-fat
Cheese Gasp! I may be expelled from the Church of Cheese for this one but I have to admit I have a packet of reduced-fat tasty in my fridge. If I'm 'eating' the cheese, as a meal for example (not unheard of), then it's triple brie all the way. But if I'm topping a healthy-homemade pizza or burger then extracting a bit of the fat never hurt anyone.
Ice-cream I've spent some time researching this one and can happily report there are some low-fat ice-creams that don't resemble frosty skim milk. (FYI Bulla Light and Cadbury Light recently got the Slimming & Health thumbs up). The low-fat version is great for smoothies and for topping with Ice Magic as a feel-good treat. Of course nothing can beat a velvety smooth scoop of Sara Lee vanilla, just ask your thighs.

Group 3: Low-fat goodies that taste just as good as the lard-laden version
Milk My stomach revolts at the thought of ingesting a full-fat milk. I actually prefer a semi-skimmed milk (that's 2% for the Napoleon Dynamite fans out there) and the skimmed stuff (zilch fat) is perfectly palatable.
Bacon The low-fat versions (Weight Watchers, Hans and Primo all make good ones) mean you can taste the salty, smokey flavour rather than just fat.

So there you have it folks, some lovely low(er)-fat goodies you can happily pop in your trolley that taste like real food and not your newspaper.

*Excludes Mrs McEvoy's Mars Bar slice. That stuff is like crack - once you start, there's no "yeah, I'll just have a little bit.' Save for very special occasions. The Mars Bar slice that is, not the crack… say no to drugs kiddies.
