Good on you Dee. Is SP the only book of David's you have bought? If so, I seriously suggest buying SP-Quit Plan. It is loaded with lots of great "how to" recommendations. It includes lists of 10-best & 10-worst in many food categories, as well useful lists of the various types of sugars, which helps you make sense of the NIPs (nutritional information panels) of foods in the supermarket. These are worth copying and carrying with you when shopping.
*Some of your comments seem to imply that you are "giving up" eating sugary stuff. As with quitting smoking, this is the top of the slippery slope. Don't "give up" anything - just think of the positive outcomes your "new way of life" will bring you. And if you do get cravings, the best way of dealing with them is to distract yourself - they'll go away in a few minutes.
The SPQP has lots of snack ideas, nuts being a popular one. A small piece of fruit is another - but no more than two a day. I have Cruskits with cream cheese and Vegemite for morning tea and an Arnott's Lattice biscuit (11% sugar) in the afternoon. When out shopping etc I have plain toast with Vegemite with my coffee. Sometimes a plain scone - I don't think they have much sugar in them. For pre-dinner nibbles with a glass of wine I have potato chips (check the sugar and polyunsaturated fat content) or Snax (ditto). You, or the cook, can also make up the sort of snack biscuits with toppings you get served at afternoon teas etc. Use low-sugar bix.
In David's books, and on this web site, there are many delicious ecipies which do not include fructose. And you can often just substitute x cups of cane sugar with 2x cups of glucose. You can buy it in the home-brew section of the supermarket.
Another piece of "advice" . . . get to love vegies! They are very low in sugar and many make nice snacks, like carrots, celery sticks and ?
FYI I'm 80yo, 185cm tall, 78kg & 96cm waist. I'd like to get that down to 94cm, as all men should to avoid a build-up of fat around the vital organs [80cm for women].
When attending dinner etc parties remember "party food is for parties" - you can have a little pig-out [piglet out?] but don't get carried away! And, like over imbibing wine, you can go extra easy the next day on sweet stuff.
