“If you have to limit them, then how can they be ‘free’?
Also, ‘speed’ food that speeds up weight loss? I’d love to see the science behind that.”
They’re not two separate things, that’s where you’re going wrong...
If you eat as much as you want of free foods, whatever they are, the chances are you’ll create enough of a calorie deficit to lose weight... over time...
I’d lose weight at 1400 calories a day, I’m tall and overweight and fairly active... so if I wanted to eat 1.3kg of chips in a day - I mean I’d struggle, that’s a hell of a lot of chips, but I’d lose weight.
If I’m managing to eat say 2200 calories of chips a day, I personally wouldn’t lose weight... but I also just physically couldn’t eat that - you’re at over 2kg of chips at that point.
However, someone used to eating that volume of food is going to weigh a lot more than me, so the chances are that they would still lose weight.
I’d lose more if I my 1.3kg of food is made up of 860g of chips and 460g of lettuce because I’ve eaten the same volume of food, but saved nearly a third of the calories... so speeds up your weight loss.
If you’re doing SW properly and not your own approximation of it, you’d be swapping out that 1/3 for veg, but you’d also be looking at why you’re still hungry enough to eat 1.3kg of chips, looking to see if actually the issue is that you’re not eating enough protein and then if it’s not that, looking at whether you’re actually eating when you’re hungry and stopping when you’re comfortably full.
