You can still eat all of them.
Watermelon scores 24 for me and I put 400gm into a 4 serving bean salad yesterday. The salad scored 90.
That's the trick with Zoe, learning what foods to combine. From your low scoring food list (none score high for me), so far this week I've had 5 of them. No day has been below 75.
Tim Spector called a 50 scoring food, for him, "average" and that's the way to think about it - some foods in the 40-60 range are average for us, not fantastically good, not bad, we can eat them often but not daily.
Lower scoring food is often something we don't need in huge quantities- so can easily be incorporated into dishes - I use dates a lot, but to enhance dishes not as a main. If I eat a dates as a treat I will pair them with nuts. 4 dates scores 27 for me, add a handful of walnuts and it's a treat of 82!
I'm loving it, lost 7kg, feeling more fit and healthy approaching 70 than I did 20yrs ago.
