Sugar (and carbs, which are sugar) are a no-no, indeed. If you're overhauling your diet, give half an hour to this
The low fat message that you and I and many others were raised with is damaging. Many adhere to it now, still. Many who are struggling and failing with losing weight. Harcombe did another good one
In fact she's done many. But I'd recommend those two.
Am I right in thinking that they say a low fat diet is 37% fat and the “high-fat” Med diet they recommend is only 4% higher at 41%
Yes, this is right. 30% reduction of CVEs. Eating 'lots of saturated fats' is hard. If you gave people discs of butter, crisps, and chocolate buttons, they'd eat all the crisps and buttons, but with the butter, they'd say 'Have you got any bread or crackers..?' If you cut out the carbs, you can't eat very much fat. We self regulate, mostly. Nobody with an over eating problem drinks glasses of olive oil.
Good luck with your overhaul, and I hope there's something of interest here![/quote]
Thank you so much for kindly supplying all this information!
I will certainly work my way through it all. It certainly makes sense what you say about the butter and crackers 
It is very hard to give up the low-fat message. I recently started eating eggs again after not eating them for many years only to read yet another report in the press just the other day saying they contain dangerous levels of cholesterol
I am slim (BMI 21) and very low cholesterol (doc thought I was on statins!). I was obese a few years ago.
Trouble is I am eating way too much refined carbs and have blood sugar swings. Also have an autoimmune condition so I am certainly not healthy. I only dog walk for exercise.
I really need to sort my entire lifestyle and diet out - So thank you so much for your assistance with this.
