It is all a personal choice but you really shouldn't need to just be eating twice a day. Slimming World has the reputation of being the glutons diet because you can eat more than a lettuce leaf.
The problem with missing meals is no doubt it'll show on the scales this week. How will you know if thats last weeks being good showing or if its the restrictive plan you've come up with working? Do you feel two meals a day is a lifestyle thats sustainable for you?
Unless you're going for a slow steady all you can eat breakfast followed by an all you can eat main meal kind of bluring your meals into one mamouth eating session. Rather like I only ever have the one glass of wine, why dirty two when you can keep refilling the same one?
Posting food diaries isn't for everyone but have you ever done it just for yourself to make sure you are counting up your syns and getting a balance of foods?
When I feel bad about a gain or lack of loss I beat myself up and want to comfort eat. Then I usually decide to be ultra good, very restrictive. I might have a very light breakfast, go on a long walk for the school/ nursery run, go swimming, be ravenous but ultra good and skip lunch (as planned) then maybe have an apple and a bananna and a yogurt, when the DC come home from school have a biscuit because I've been so good and not had lunch, then have a low syn bag of crisps and maybe hoover up a few bits of biscuit the DC haven't eaten. Then i'll prep the DC tea and no doubt the odd bit will be tasted. Serve up the DC tea checking its not to hot by having a generous sampling. Finally have an icelolly with the DC because its within my syns and I've been good.
Once the DC are in bed I'll prep tea for DH and I and as I haven't really eaten all day I'll pick as I go. Serve up massive portions as i'm starving (as could clearly be seen by the five to six extra stone I've been carrying around). As I've only had an icelolly and low syn bag or crisps a lowish syn glass of wine wont hurt and I'll finish my syns of with a small chocolate that can only be a syn. But hang on a minute I've still got my b choice so go to bed with a milky decaf coffee and two hifi light bars.
A being good day if I add up all the little bits can easily be 30 syns. I'm far better off having a big breakfast, a series of planned fruit/ veg/ hifi bar snacks, omlette/ jacket potato/ soup for lunch then a planned snack when the DC have biscuits and planned tea preped with the DC's so if I pick its better choices. I pick far less that way.
We eat quite a few veg based meals, i love meat too but enjoy lots of veg based food and find it cheaper.
I find ways of adding more veg as bulk by adding a generous handful of green beans, wild garlic, stock and a cup of peas to my rice to have with my veg curry. This no doubt cuts down the amount of rice i take whilst it looks like a very big meal on the plate.
My favorite pasta is arribiatta but I also do a simple tomato, onion, garlic and herb with spaghetti and a big lightly dressed salad on the side of the plate.
Rissoto and fried rice dishes are other good ones you can add so much veg that you have a massive plate of food that isn't just carbs.
I have an actifry and do a root veg hash of cubed potatos, carrots, swede, parsnip, sweet potato and usually red onion and a handful of herbs. Its a bulky potato based side but less carby than just potato but with the same carb bulk feel when you eat it.
