There is always going to be a low-fat food industry, certainly for as long as any of us will live. The simple fact is that people want to lose weight, and anyone with business acumen can make themselves a large amount of money by seeking to cater to that wish. Or, at the very least, they will seek to appear to cater to it. it does not take much research, though, to see that a lot of the additives in low fat foods as sold ready-made in supermarkets can actually be detrimental to your health. In some cases, they will be more harmful than any typical “full fat” option.
It is natural to look at low fat foods as a way to eat the same basic thing without suffering the health consequences. However, the fact of the matter is that there is only so much that can be achieved by hoovering all of the salt or sugar out of a dish and replacing it with lower-calorie alternatives, and the same goes for any kind of “like for like” substitution. Real weight loss comes from changing something more substantial. A chocolate bar or a soft drink may well be sold in great numbers with the tendentious claim that it is “Diet” or “light”. But get down to brass tacks, read the list of additives and you will find it is scarcely any better for you. Replace a daily chocolate bar with a handful of Acai berries and you will get much further in your ambitions.
