I try and break my points into 4 (breakfast, lunch, dinner, snacks) so that'd be 7 points each for 28 points, so you could have egg on toast and a cuppa for breakfast, soup and a roll for lunch and a small chop and tonnes of veg for tea, and then have 7 points floating around for sugar/milk in hot drinks, or a cheeky packet of m&ms.... I break my weeklies up to 7 a day, and personally if I don't use monday's set of 7 weeklies on monday then I don't use them at all, I see them as a buffer, not an excuse if that makes sense?
Good luck with WW btw
