How long does 'good behaviour' take to kick in?

I have A LOT of weight to loose. I have got myself into really bad eating habits over the years which include no breakfast, then snacking on large bags of crisps and biscuits all day, then a meal at supper, then more snacking at night.
This last week I have been eating porridge (with syrup admittedly) for breakfast, 2 x cup-a-soups for lunch, and a dinner in the evening. No snacking after dinner at all.
I have put ON 4 lbs.
I know I have to include exercise, and have managed 1x 10min workout this week ( then my knees hurt, so I guess I have to build it up slowly and steadily), but I didn't expect to put weight ON. Is this normal? I really really have been good. I have not eaten any crisps - a miracle in itself, and succumbed to 1 biscuit this evening.

Could it be that you are not eating enough calories so your body is going in to 'starvation mode' and is laying down fat just in case? Or are you over compensating with a larger evening meal? It could be worth using an app like MFP for a week to find out how many calories you are actually consuming.

I would be careful with scales though. I weigh myself all the time ( the bLood sugar diet recommends this) and there is a 3 pound difference between morning and evening weight. You should lose something after a week of eating less though.
I would stop eating crap ie. processed cup a soups and eat real food and the same with dinner. Make sure the dinner is protein and veg and not all starch and carbs.
Good luck. It will be worth it!

That's very disheartening op, but what's very likely the cause was that what you ate prior to starting your week of cutting back has shown up. Weight gain or loss isn't very linear, it can take 7-10 days for weight to appear, so your start date was off. Do you use anything to track your calories? Like mfp? Find out how many calories you need to eat, according to your current weight/height, so you have an allowance to work with. Weigh your food out until you're happy you're recording the amounts correctly. I reckon 1500 calories a day with a half hour walk, 8 glasses of water a day, low'ish carb/good fats/v little processed food/lots of veg will yield most people with a couple of stone or more to lose a solid 1-2 pound a week. I know that doesn't sound much but it would be doable & likely to be easy'ish to stick with. Come join us on the mfp thread for company & advice if you famcy

thanks people. I guess I have to be patient. I think my eating habits are so bad, every step must be a step in the right direction. I'll have to be careful this week being on half term with the kids at home...
