Welcome to Social Slimmers, and congratulations on your fantastic loss so far!
First of all, let me put this into perspective for you:
Smaller losses (particularly on Slimming World, where your initial losses can tend to be huge) can be disheartening, but remember: weight is easier to keep off when you lose it slowly and steadily.
Now, some key areas where people can tend to fall down: not keeping full track of what you are eating and drinking. Do you keep a food diary each day? Do you make meal plans in advance? And are you drinking enough water?
If you are doing all of these things, think about asking your SW consultant for an SAS log to see if she/he can identify any problem areas that may be holding you back. You can also post a food diary in the
Dieting Journals subforum here to see if we can do the same.
Are you making sure to have at least 5 syns per day? It may sound counter-intuitive when your goal is to lose weight, but remember that SW is essentially a low-fat diet. Your body still needs fats to burn off, and it's important to not feel deprived, so make sure to have at least the minimum of the recommended amount each day. I've found that my losses are better when I'm making sure to have syns each day--and this doesn't have to be scoffing chocolate or crisps! It can be as simple as incorporating them into your meals, for instance using dressing on a salad, low-syn sausages, a little extra cheese, etc. And you can go for 'healthy' syns as well in the form of dried fruit, nuts and seeds, and so on.
Following on from that (and this is going to sound REALLY counter-intuitive, but bear with me), have you thought about having the odd 'cheat meal'? Everyone is different so it may not work for you, but I've found that sometimes having something really naughty (like a pizza) can spur me on... or at least kill the cravings!
And finally, have you increased your exercise since being on the plan? If so, it's possible that you're experiencing smaller/slower losses because you're building muscle, which weighs more than fat. A great tip is not just to weigh in, but also keep track of your measurements. Sometimes you'll see a small loss but a significant change in measurements, and I find it helpful to have these as a back-up when I need a lift after a small loss/maintain.
As for how much I eat in a day, I make sure to have all three main meals plus snacks in between if I get peckish. I eat until I'm full, not necessarily until my plate is clean, and it's rare that I'm REALLY hungry (unless right before a meal, of course) because the beauty of the SW plan is that it helps you to break bad habits and develop a healthier relationship with food.
I hope this has been helpful, and I'm looking forward to seeing your progress!
