I am a 73 year old woman, 5'4" tall and now weigh 15 stone, with a BMI of 36. Two years ago, I weighed just over 12 stones. I haven't changed what goes into my mouth or the amount of exercise I do. This is quite minimal, as I have had two spinal surgeries, and have spinal, hip and knee arthritis (I must confess to being a couch potato!) When I am "on track", I use the Fat Secret app for recording weight and food. (If you haven't come a cross this, it is very helpful.) I recently watched "That Sugar Film" on USA Netflix), an Australian documentary, where a fit young man spent 60 days on a so-called healthy diet, eating only foods that claim to be healthy (anything low fat, smoothes, breakfast bars, etc). Before the experiment, he consumed 2300 calories a day. The same during the experiment, YET he gained over a stone, developed a fatty liver, and other health problems. So, my concern is that the NHS recommends us to choose low fat options, when generally these contain more sugar. I know that the only truly healthy option is to eat only non-processed food, but hard to do. Any advice for those of us in our prime will be greatly appreciated.
