Hi Graham,
I have the “The 8-Week Blood Sugar Diet Recipe Book” by Clare Bailey.
I use it for ideas rather than follow it religiously (e.g. I’m allergic to eggs).
I use myFitnessPal to log everything that goes down my throat. It’s gives a reasonably accurate view of calories, carbs, fat and protein. It also give an indication of sodium, potassium, vitamins, etc. which I found useful. If you use a combination of the app for logging and the website for reporting and analysis, you don’t really need to pay a subscription. It’s easy to use and has kept me on track. If there’s dishes you like, you can add all the ingredients as a recipe so they become a one-shot entry. When I have had blips, I can usually determine the cause from the myFitnessPal logs.
I’ve also been logging my weight in an excel spreadsheet every morning. It reports the loss for the day, total loss, % loss since start, % loss in last 7 days, predicts a date for my target milestone weights and predicts a weight at the end of the eight week period. I find this stuff motivational.
From a bloke perspective: The diet has and is working in terms of weight loss. I’m on day 37 and I’m down from 135kg to 121.5kg which is a 10% loss. So far, it’s been relatively easy – I don’t really have hunger. Sometimes feel a bit weak and sometimes a bit constipated even though I drink 3.5l of water a day now. My only concern is that my fasting BG tests are still hovering in the mid to high 6’s (mmol/L) after an initial rapid drop from the high 9’s. (I have tried waiting until later in the morning, using a variety of meters & calibrating again a test in the doctor’s surgery)
Best wishes! I hope your experience is as positive as mine.
