Hi Leish, My husband is one of those skinny types and he never puts on weight! There are a few things that I can share with you from my experiences, so I hope that they help.
Firstly, weekends are usually the killer, but I found that by having ready meals in the freezer are great. The Lean Cuisine actually have pizzas now, (however I don't know what they are like) but it might pay you to try one and if you like them keep them handy. This way your other half can have pizza and you can too (and know that it is a healthier option). Alternately, you can whip up a pizza by using pita breads as a base. Same goes with Hungry Jacks. I am not sure if they have a healthy choice menu like Maccas do, but if they do choose something from there. If they don't, you could try just slipping in elsewhere and getting something healthy. On Saturday just gone, my family wanted sausage rolls for lunch (my husband works in a pie shop!) and I just told him that I didn't want sausage rolls and could he please take me elsewhere. I ended up ordering a chicken and salad sandwich and he went and got sausage rolls for him and the kids. Another quick healthy option would be Subway. They have plenty of low fat healthy options, even low-carb and no-carb options. Don't stress too much about the BBQ chicken, as long as you remove all the skin and throw it away it is ok, try popping it onto a roll with some salad for bulk or even just with a salad on a plate.
I know how hard it is to resist the temptations of takeaway, but it does get easier. The more healthy choice options you make, the stronger your resistance will become and you will find that there is always an easy healthy option, just as there is a high fat one.
Another way to combat the dishes thing......I usually keep a stock of plastic plates and dishes for the weekend. I find that this helps as you are not faced with a pile of dishes over the weekend and you get a break from the dishes as well!!!
I am not sure what you time schedule is like, but if you find that you have some time to spend in the kitchen, cook some meals for the freezer. That way you always have something on hand that you know is not going to sabotage your wonderful weight loss efforts!!
My hubbie is very supportive but I find that as soon as I say that I am starting to change my lifestyle to a healthier one, he suggests things like, 'will you have a piece of pav if I go and get one?' He always seems to get these cravings, but thankfully he recognises this the same as me and we have worked out a solution. If he really wants then he can go and get one, but on the understanding that I will not join him for it. I don't stop him and the kids having things, but I have to stay strong and say no.
Sorry if this has been an epic! But I do hope that it helps you, good luck and happy slimming!!
