I'm doing slimming world and have lost 2st12 since May. In that time I've turned 40, had both my parents had 70th parties and I've been away on two holidays. ironically, I'm eating more than i ever have.
The main elements of the diet are very low fat - less than 5%, eating to satisfy your appetite with 1/3 of each plateful being veg and controlling but not stopping sin foods like bread, crisps, chocolates, alcohol.
The food list you gave would be a very high sin day due to lots of bread and breaded products. The bread, crisps, a couple of plain biscuits and two breaded processed products would equate within the slimming world plan to equivalent to several glasses of wine and bars of chocolate.
It may well be that for you two thick bits of bread is infinitely preferable to for example a bar of chocolate and glass of wine but slimming world has taught me to make these decisions for my own tastes and as a result I'm loosing weight and eating more.
A typical day for me now starts with a cooked breakfast typically bacon medallions, egg in some form, a low fat sausage, mushrooms and tomatos. I tend to have a big mug of milky coffee to get me going too.
For lunch i might have a jacket potato loaded with cottage cheese and smoked salmon and a salad, or an omelette, a mixed bean soup, a pasta and sauce dish.
Snack with the DC of fruit and ice-lollies (mini milk are very low sin and homemade even better)
This evening we're having wild garlic rice and curry (big portions). We eat lots of pasta dishes and things like steak and actifry chips.
Before bed I'll have a small bar of chocolate with another milky decaf coffee.
This past week eating this way I dropped 3 lb. 1.5lb the week before (but we'd had a day out and eaten out) and 2lb the week before to.
Before starting the plan I thought I knew all the right things to eat, quite a bit about healthy eating etc but when I tried to loose weight I always seamed to be starving myself or heavily restricting myself. Now I can confidently eat out, find things that are preferable to eat at a buffet and i know which drinks to opt for to minimise weight gain. But the biggest thing is I'm not scarred of food. If DH and I go out for a curry, I eat everything I want then just go back onto plan the next day.
I'm walking and swimming lots because I enjoy it. My sister is at a very similar weight loss and is a self confessed couch potato. She just hates exercise in all forms and has done since childhood. So its the eating regime thats making the difference.
Making a decision to do something is the first big step. Good luck which ever way you go.
