The mashed banana and the pasta stories make me laugh
I do go to SW, I follow it very loosely , I am target member, I dont pay.
The idea of syning a banana once its mashed, is to limit the amount of that you eat. Two whole bananas is likely to pretty much fill you, two mashed ones wouldn't fill a crack in your tooth and you will be reaching for something else
Every dietician will tell you to limit fruit that is not in its natural form because whilst fruit is good for you, its also high in sugar and acid and the real benefit of fruit comes from the fibre. NHS England only recommend 1 small glass of juice or smoothie for your 5 a day so is it wrong that SW also say eat fruit whole?
I was a eat as much as I could pasta eater this time last year, seriously I would easily sit and eat a whole packet of pasta, covered in olive oil and parmesan and kid myself it was healthy - olive oil is good for you, parmesan -full of calcium. So I rock up to SW and happy days - shovel in the pasta, eat as much as I wanted, only olive oil is 6 syns a tablespoonful and god alone knows how many syns in the parmesan so I had to choose to change what I ate with the pasta, or go without the glass of wine. So I chose a vegetable based sauce and had the wine :) Because now Im chucking in veggies and tuna or salmon, I cant eat as much pasta, Im getting full on less pasta and because Im adding fish and veg Im eating more nutritious food , and Im still getting a glass of wine :)
Thats how the syn system works. For me no diet that says I cant have a drink is going to work so I choose my syns wisely - wine usually and my meals are made up of what SW calls free or speed foods - low calorie nutritionally rich foods
Even a bacon butty is now a BLT, I shovel in the lettuce and tomatoes and bacon medallions - huge butties - on wholemeal instead of white, no butter or spread - keeps me full and not wanting to eat between meals
