I got the following from an ex-Jenny Craig rep:

Approx. 90 grams per day. 1 serve is 15 grms and you aim to have 6 per day (15 x 6 = 90)

Good choices include:

Beans & Lentils (3/4 cup)
Bread (1 slice = 30 grams or two serves)
Cereal, rice or pasta (1/2 cup)
Low fat crackers (4)
Salada (6 squares)
Roll, English Muffin, pita, bagel (1/2 = 30 grams)
Starchy veg such as potato, corn, peas, pumpkin (1/2 cup)


Least favourable choices include:

Plain cake (5 cm square)
Sweet biscuits (2 small)
Crackers (4)
Museli Bar (35 gms)
Hummus (1/3 cup)
Low fat icecream (1/2 cup)
Pancakes, scone, muffin (1 small, 45 gms)

Thanks Rhi I am actually loosely following the CSIRO low gi plan so some of the 'good choices' are out.

So I am doing -

3 units lean protein (one unit is roughly 100gm of lean meat or an egg)
2 units starchy carbs (one unit is 1/2 cup cooked potato/pasta/rice or one slice wholegrain bread)
1 unit high fibre cereal (40 gms)
3 units dairy (250ml milk/200gm yogurt or custard/25gm cheese/50gm low fat cheese)
2 units fruit
Pretty much unlimited non starchy veg.
3 units fats and oils (1ts oil/60gm avocado/20gm nuts)
