The problem with all of this is it isn't starting at the right place. Focusing on calories and sugar isn't going to improve health. I was counting calories and cutting out desserts and walking a couple of miles most days for years. I got ever fatter, and more and more ill.
It's easy to watch the TV and wonder how a certain nation can be hoodwinked by the lies its leader is telling them. But isn't that what our government/s have done/is doing to us? The majority of people believe that fat is the enemy and sugar is naughty but nice. Eat less, move more yadayadayada. Well the NHS says so, so it must be right! And yes there's some truth in it, exercise IS good for us and if someone continually consumes more than their body can burn then they will gain weight. But that's not all of the story. Adding a little truth to the mix just confuses the issue and blinds us to seeing the full picture.
The first change that needs making is for 'healthy eating' guidelines to change. We have been told for so long that dietary fat is bad that we believe it...until like mine, our bodies prove the 'facts' to be wrong. Fat is necessary for life. The low fat message is so strong that people fill up with carbs, not just sugar. Then people feel guilty and like failures just for feeling hungry all the time. It's the diet that's causing the hunger. Obese people are not all weak willed gluttons, they have been misled until they give up trying.
The message that needs to go out there is that natural fats are good. Highly processed seed oils and trans fats are bad. Carbs are addictive. This has naff all to do with calories on menus which is just another trick to keep us eating the carbs.
