...Some food for thought...('Scuse the pun!) - Above all, enjoy tomorrow...
Also consider Calorie intake...consider dropping 1 product possibly 2 (not sure if you're on 4 a day or 3) but either way, you drop 200 Cals off per product, so if on 4 a day consider dropping 2 products for 400 Cal reduction to take into consideration 'Real Lunch' - which if it's 1000 Cals, then your net intake for the day is only 600 Cals more...But then there's Saturday too...Drop one product and that's another 200 Cal saving, so net additional Calorie intake of 400 Cals over 2 days (Or swap that for Sunday for 3 products) - thats IF you swallow 1000 Cals for lunch in the first place - enjoy and be mindful...
You choose... 😉
Of course, your dietician is correct to stick to the plan, but you can be clever with it also...which is what I do now to maintain - you can have the special occasions - and they are 'Occasions' (not all the time) and still maintain long term...
You deserve to enjoy yourself once in a while and still remain on track 😉
FYI - I have done the 'Good Food, Bad Food' thing also - and concluded ALL food is good eaten in a mindul moderated way...
Hope this helps ya 🙂
