My BMR is approx 1439 & today I've eaten 2432 Calories, will that gain weight?

It's my first day on my diet to gain some weight, I'd like to add at least half a stone within a month or so.

I've had my BMR calculated & my BMR is approx 1439, today I've eaten a total of 2432 Calories (Probably more as I've only counted solid foods & not extras such as butter & drinks), so I've definitely eaten around 1,000 more calories than my body is burning off (I'm above).

I know that I never ate that many calories previously & it is my first day, which has gone well & I've actually enjoyed the challenge & keeping note of my intake, however now I'm feeling kinda bloated & not sure if I can reach the 3500 Calories today (Which i know equals 1lb, so to be 3,500 cal ahead I'd need to eat around 5,000 Cal (approx) per day, however this is for putting on 1lb per day, which I probably don't need to do anyway).

Has it beneifted me today then & have a I done well, I'm still going to try a little extra before I sleep however it is my 1st day & i guess i have to adapt.

Before today, I was definitely eating less calories than my body was burning up, where as now I'm over the calorie intake my body is burning & I feel good also, just that I'm not sure I can meet the target of 3,500 Calories or as an axtra 1lb per day, 5,000 calories approx.

Whats your views on this, I only want to put on say hualf a stone in the next month or so anyway, so 1lb per day would work out me putting on about 2 stone per month anyway.

Thanks to all who kindly add some advice, I really appreciate it.

BMR only accounts for what you need to stay alive. It does not account for activity. So if you are walking, cleaning or exercising, you will burn more calories and will have to compensate.
