Hi, I have an under active thyroid and have been prone to weight gain. What I noticed was that once I got to fifty even though I exercised a lot, and ate very healthy, I was still carrying too much weight. Two years ago I started researching foods etc. back in the 1970's an American Doctor Ancel Keys recommended the high carb low fat diet, which the world went for. It was argued by a British Professor Yudkin, I believe his name was that a low carb high fat diet was better. The result of the high carb diet is now what we are seeing, diabetes, obesity, heart related problems, we do not need as many starchy carbs as we are having. Even if you eat wholemeal pasta, rice etc. unless you do copious amounts of exercise you do not need three portions of starchy carbs a day. I found this hard to believe, but spoke to two personal trainers who confirmed that the new science is that we can get all the energy from one portion of starchy carbs, as long as we eat plenty of vegetables.
i changed my low fat diet to a normal fat diet. I longer no had low fat yoghurts because of the sugar, I swapped these for full fat Greek yoghurt, I eat full fat cheese, I have cream, I eat lots of nuts and seeds and all the usual healthy foods but I only have one portion of starchy carbs a day. By starchy carbs I mean pasta, bread, rice, cereals, cakes, biscuits and all that kind of stuff. I fill my plate with vegetables and protein, I reduced my fruit intake from five portions to one. This is due to the sugar content. I lost 11 lb over a few months, that was all I needed to lose. I can do a 30 mile bike ride or a spin class or five mile run on one portion of starch carbs and plenty of veg. Even all the nuts I ate allowed me to lose weight. I also started cooking in coconut oil. When I had a health check last year my cholesterol level had increased from 3-4 to 5.8 the nurse said they did not like it being over five but my cholesterol was so high in good fats from the nuts and advocados, that it did not matter it was over five.
sign up for DR Mercola's blogs he gives a lot of good advice on this. Some people think Dr Keys was corrupt and wanted to promote the sugar industry back in the 1970's hence why he went for that diet. If you look at the research the USA reduced their fat content but the obesity etc has not decreased, nor has the heart attack rate. So low fat is not good for us. Our brain needs fat. Our bodies can use good fats, even saturated fats can be used as energy. It is a fallacy to avoid fat and they even think that low fat diets may be the cause of thyroid problems.
