I’ve only ever controlled my weight with calorie counting and portion control but I’m old enough to remember a landlady of mine doing red and green days, when Syns were Sins, so that guff about synergy doesn’t wash with me. The whole concept is so, so harmful. Fat is demonised to the point of oblivion (full fat, anyone?) and artificial sweeteners and simple carbs are pushed into first place, making you more and more hungry and dissatisfied until you give up and binge on all the things that actually were not allowed on SW, despite their claims that no food is banned. Nikki has never had a weight problem, its so sad that her life has been, and still is dominated by this SW crap.
The consultant on the podcast that I mentioned before went on to say (in a dreamy voice) that ‘free’ food is your friend, so you could eat (stuff like eggs and pasta) 24 hours a day and still be on plan! Thankfully her co host shut her down after that one.
I hope you find a place of peace and happiness with your weight, food and dieting can take up so much headspace.
