Cheat day

Concerning the 2 pounds you've put on, unless you consumed 7000 calories over your TDEE, you won't have put on 2 pounds in actual weight/fat. It's likely water retention. Make sure you're drinking enough water and lower your sodium intake. Also, this will sound disgusting but if you haven't had a bowel movement for a few days or so, that's where the extra weight might be coming from.

As for the cheat day question, it'll only affect you if you massively went over your allowance. Just eat less and exercise more tomorrow to work it off and it should even out. It's upto you how often you have a "cheat day" but personally I think you'd be better off incorporating the foods you like into your daily lifestyle but moderating how much of it you eat so it fits in with your calorie goals instead of having a full blown "cheat day". I used to have cheat days and I'd feel miserable afterwards because I was restricting myself 6 days a week and then going all out on this one day. It never affected my progress but it still made me feel guilty. Adding in the foods I like to my daily lifestyle and exercising moderation over it is so much better for me, I now don't have the need for a cheat day and I get to eat what I want without feeling guilty for it because I'm still under my calorie goal a lot of the time. But if you are gonna stick with the whole cheat day thing then I'd recommend once a week.

Hi i have just started dieting and i am a big person with a few things to ask.
My allowance is 1960 calories a day and i probably have on acerage 1400 a day isually i weigh myself in the mornings but i weighed myself yesterday night and i had put 2 pounds on since sunday.
Also today was my first cheat day and the first time i have ever been over my calories will this affect me and how often should i have a cheat day? Thanks for helping

I weigh myself every day, but you have to be sure you're weighing in at the same time and in the same conditions. For most people, in the morning after they wake up, in the nude typically, after using the toilet. You just have to understand that your weight fluctuates every day, every week, every month, etc. Being up does not mean an 'actual' gain, just like being down may not mean an 'actual' loss, it's the overall average of a downward trend that you're looking for which is why most people recommend weighing in once a week only. Most just can't objectively look at the weight they see on the scale as a single data point in the overall big picture, but that's all it is.
