I love graphs, I use a spreadsheet to track everything I eat as well as my weights and measurements and automatically generate them. I even use them for showing the food contents for meals I'm planning to eat. Ironically it's mostly pie charts as I don't eat pies any more!
These charts show how I'm trying to cut down on carbs, lose weight, improve muscle mass and improve my fibre intake (I reckon I was at about 10g a day before I started).
I find that trying to cut salt intake down is *really* difficult.
I plan to move the target balance more towards 25% each for protein and fats, 40% carbs and 10% fibre once I have built up enough muscle.
Because they are automatically generated, I can easily see what meals affect the balance. I find them a great help and am using my obsessive nature to my advantage.
If you're having fish today, you might not want to read the next part.
I'm thinking about buying some keto sticks to see if I'm reaching ketosis. My pee smells a bit like tuna which, apparently, can be a good sign (and happened when I went carb free last year). The sticks measure the ketones in your urine to see if your body is breaking down fat for energy. This is important for low carb diets. I drink around 4 litres of water a day and am having my blood tested in less than 2 weeks for type 2 diabetes. I don't have any pain and pee frequently, so I'm looking at the good signs, rather than the bad.
