I can’t think of any answer to this other than the below. I know it’s not what you want to hear but it’s the best advice i can think to offer:
Scrap the Slimming World and download Myfitnesspal. Use a calculator to find a rough TDEE estimate. Eat exactly that many calories for two weeks. Weigh every two days and record the weight in the Myfitnesspal app.
Weight goes up = Eat less calories.
Weight goes down = Eat that number of calories until you reach your goal weight.
I’ve seen a lot of people lose a lot of weight with Slimming World, but they never learn about the balance of energy in and energy out and its relationship with bodyweight, so 7/9 have all put the weight back on.
Huel is an absolutely perfect product to begin your weight loss journey with. Easily recordable calories and great macro balance.
To answer your questions - no, no, 20 syns (you normally get up to 15).
For the sake of marital harmony I would have the huel breakfast and the SW friendly lunch and dinner. If they are on plan then they should be naturally low in calories anyway and just improving your diet might be enough to start shifting weight. If you want to count the calories then just input the meal into MFP or whatever app you are using. No reason why it has to be one way or the other.
Sorry. Just realised this thread is two weeks old but won’t delete in case my reply is still of use to anyone
Hi all. I’ve recently joined SW to help my wife with her weight loss (she refuses to go with Huel, having tried it a few times and hated it) so I’ll be having a SW breakfast and dinner with her, and Huel for lunch.
The SW rep told me today that 100g of Huel (402 calories) is 20 Syns, however the “Healthy B” can be used on oats so 40g of the allowance can be “free” and the final 60g of Huel would cost 10 Syns from my allowance.
The way I see it is I’ll take that for a spin and see if I’m losing weight. If I’m not I’ll revisit and if I am I’ll stick with it. The main gal for my weight-loss is to get into shape to commute my full 16 mile round trip on the bike daily rather than doing half journeys every few days so my metabolism will improve and hopefully not be impacted by any “bounce” from the SW diet.
The same can be said about any diet change to be honest; people go from their natural habit of eating x or y bad foods to eating healthily and that makes it easy to revert back to old habits. The biggest positive I can see with SW is the education piece on balancing food types, what foods are great for you and limiting the bad foods (albeit they have a ridiculous bespoke Syn thing going on) and trading ideas on how to replace bad foods with good ones that perhaps people wouldn’t have thought about before.
There’s also a whole section on exercise (although realistically there isn’t a single person in the group who exercises. Ever. Other than me commuting by bike)
