I really, really don't get the hate for SW. Some people are absolutely vitriolic about it and it just seems odd to me.
I'm on it now, currently a couple of months and 9.5lbs down. It would be more than that except for a fortnight's holiday where I returned to my previous awful eating habits and undid about half of my work last month. That's not a sign that SW 'doesn't work', just that like anything if you don't actually stick to it it won't yield results. Now back on track though, regained my lost ground and moving forward.
I find it incredibly straightforward. Eat as much fruit, veg, salad, lean meat as you like. Unlimited rice/pasta/noodles. An allowance of healthy dairy (milk/cheese) and healthy fibre (wholemeal bread/cereal) per day. Everything else in very limited quantities due to syn values.
People obsess over the unlimited rice and pasta. 'HOW can you, that will never work' etc. Nonsense. The vast majority of fat people I know (including me, 5 stone to lose when I started) aren't obese because they eat too much plain rice 😂
I find it freeing. No calorie counting, just a hefty push to make healthier choices. I eye up a bag of walkers and think bloody hell that's probably about 9 syns. Not worth it. I'll pick up an apple instead. Similarly with chocolate, my ultimate downfall. I eye up a big bar like I'd used to eat and its 25 syns. So I eat a curly wurly every evening instead which is 5 syns...and for those that work in calories, less than 100.
I feel that constantly obsessing over calories and counting every item into your mouth is probably more damaging and likely to contribute to ED's than SW where you have a huge list of free food.
My sister is currently doing a 'standard' calorie controlled diet and meticulously measures and counts everything, including every item in her plain salad.
I can't imagine having to measure the calories in a plate of cucumber sticks. That would make me utterly miserable.
