Dieting is a numbers game...

New research reminds us of the importance of calorie counting! And I've just determined that my magic number (at the moment, of course) is 1912!

Who would choose a high sugar diet? Look at any low fat diet before you answer!

Perhaps the easiest weight losses I've encountered in recent years have been thanks to low-fat, no-nonsense eating plans like Weight Watchers. But then again, I'm 18-plus stone now... What is that telling you?!?

Your modern low-fat commercially produced food isn't just low calorie, it's tasty to boot! Weight Watchers chocolate mousses are my personal favourite. They really hit the spot, fulfil my sweet cravings and they're low fat, too. Their low calorie and saturated fat levels mean they weigh in at just 1.5 points.

But, according to Australian professor Kerin O'Dea, of St Vincent's Institute in Sydney, everything isn't quite as healthy (or non-addictive) as it might seem.  In 2008 she cautioned that food manufacturers are using increased amounts of fructose - a cheap, sugary corn syrup - to enhance flavour of 'diet foods'.  High levels of fructose can be found in: 
  •  Breakfast cereals
  • Low-fat yoghurts
  • Cereal bars
  • Juices
  • Low-fat peanut butter
  • Salad dressings

 Prof O'Dea warns: "The argument that obesity is driven by high fat intakes has led to a proliferation of low-fat processed foods... but many of the low-fat products, especially the `99 per cent fat free', are loaded with sugars and kilojoules." 

Prof. O'Dea explained that reducing the level of a fat in a product has a direct effect on the levels of carbohydrate or protein. These would need to compensate by increasing. 
 
She warns that fructose is most dangerous as it doesen't stimulate insulin secretion or leptin: the two crucial hormones that help make people feel full.   

 
She explains: "You can consume fructose and not feel like you have eaten much. It does not make people feel full and it is getting under the radar... and if you are well nourished and don't need it, then the fructose goes through the liver and is converted into fat. While fructose was added to low-fat products to improve the taste, food manufacturers found the holy grail because people started consuming more of it because they thought it was healthy and they were still hungry."

  
The professor goes as far as to say: "People would be better off eating a full-fat plain yoghurt than a low-fat yoghurt."

 

Fructose appears under many names on food labels. These include:
  • corn syrup
  • hydrolysed corn starch
  • sucrose 
And if you're still stuck for a reason to ditch the sugar? (Besides the obvious diabetes risk, of course!)

Researchers at Rockefeller University and the University of California at Berkeley found that people on weight maintenance diets which were low-fat but high-sugar had an increased production of saturated fat (1996). 

 

 "Our study suggests that low-fat diets designed to maintain - not lose-weight could be a hazard for people who also eat lots of simple carbohydrates, mostly sugars," says Lisa Cooper Hudgins, M.D., assistant professor in the Laboratory of Human Behavior and Metabolism at Rockefeller. "Current public health recommendations suggest that people should reduce fat in their diets and increase their carbohydrates. However, too great a reduction in fats and too much of an increase in simple carbohydrates may prompt the body to make the sugar into saturated fats, which could harm the heart and blood vessels."

More than 3 years since I started...

And, well, I think I may - finally - be on the right track! After months and months of weight fluctuations, I seem to be on the downward slope to health. Christmas 2009 saw my weight peak at 20 stone. That's a figure that is both shocking and upsetting for me. Firstly it was my highest ever weight to date. Secondly, when you hear stories of extreme obesity, that figure in stones is never in the teens.

Worse still, my son was on the same path. At 10, he weighed 9 stone 4lbs and lived on junk (like me). Luckily for us both, we started a 6-month healthy eating/ healthy living programme called Mend and the results have been phenomenal for him. While he's still got a way to go, he's down tbelow 8 stone and is full of energy and eats healthily.

The changes we've made to our food intake and activity levels have seen my weight drop, too. Starting the year at 20 stone, my weight's now down to 18 stone 9lbs. It's nowhere close to the drops I made previously, but I haven't officially been dieting. This is just from modifying the foods I've eaten while at home. As for exercise, this is only just being reintroduced as I'm recovering from an impinged shoulder which cramped my activity levels a bit.

Every day in this blog I aim to examine one of the changes we've made or are going to make. I also hope to uncover where the fad diets are going wrong for the average Joe (but right for the diet creator).

It's the same journey... just on a new path!
