Calorie deficit for 2lbs a week

It's saying eat 1450 before exercise. So when you workout, you get to eat those calories back. But even then that may still be to low for you. My guess is that you may be underestimating your activity level.

You can't really expect 2lb a week. It's an option that shouldn't really exist on this website, in my opinion, and certainly not as one of the first choices presented to you.

Anyway, I would advise you to calculate your TDEE and work from there. Any cut from your TDEE will result in weightloss (theoretically - you may need to adjust it a couple of hundred calories if nothing happens).

You shouldn't be eating under your BMR.

Over BMR, under TDEE.

This.

Eating below your BMR is DEFINITELY safe if you're overweight, first off, so everyone can stop saying that. Eating 1450 is definitely doable, but if you feel like it's impossible to sustain then DON'T DO IT, because if you're constantly hungry it makes it that much easier to fall off the bandwagon. There's no rush to lose weight, there's no competition, the change you're trying to make is for the rest of your life. Eat at a sustainable amount, especially since you're starting off, then see if you can lower it by 100 calories in a few weeks, a etc. Going from ~2500 calories a day (estimating your typical caloric consumption) to 1400 is a huge jump and you'll be hungry all the time because you're used to eating a lot more. Don't push yourself.

OK it is not s scary as you think.

Your BMR calculated on MFP is 1450 right? He said his BMR calculated to over 1900

So the minimum you are going to consume is 1450 .

Now you add exercise calories, the more you exercise the more you get to eat.

You can go down the TDEE route by visiting a website called scooby and adding your total daily energy expenditure

I think you could eat more than this! I'm 5'5 woman and eat a net of 1400 and losing steadily at around 1 or 2 lbs a week. I'm 122lbs so being a guy and heavier I reckon you could easy up your cals and still lose weight!

Ok, I'll try and give some advice on the information we've got. I'm not promising a massive amount of accuracy, just a starting point.

BMR is what you would eat to maintain weight in a coma. If you are sedentary (desk job and drive everywhere) - lightly active (1-3 days exercise a week/lots of walking or job where you are on your feet/on the move) your TDEE (what you burn in a day) will be between 2300 and 2700 cals a day (roughly, I'm doing the calc in my head).

If you only have 45lbs to lose it would be better to lose 1lb a week as you are more likely to maintain this regime in the long run. You then only have to go 500 cals below your TDEE to lose weight. That should be around 1800 - 2200 cals. Try it for 4-6 weeks and see how it's going after that. You do not eat your exercise calories back with this method.

It will also be beneficial for you to take up weight training 2-4 days a week with progressive loading (weights get heavier each workout) so you can retain your muscle which will help your BMR stay higher and enable you to eat more and make it more likely you will stick to the plan this time. Otherwise you will have to keep reducing your calories as you lose weight.

Your BMR calculated on MFP is 1450 right?

No, my BMR is 1944. The app is telling me to eat 1440 calories a day and do 1470 calories of exercise a week for a 2lbs loss. Sounds extreme seeing as my TDEE is 2502. it might be right though. Perhaps I just need to eat less.

Based on a TDEE of 2500, just eat 2000 a day and don't eat back exercise cals. The 500 is a pound a week, plus whatever external deficit you create through exercise.

You shouldn't be eating under your BMR.

Over BMR, under TDEE.

Yes, most people eat too many Kcals a day! I am suppose to eat 1210 and that is for 1.5 lb weight loss. I am shorter and a woman however if I were to lose 2 lbs a week it would be 900kcals per day. You have to understand that losing 2lbs per week is like cutting your kcals with diet and exercise 1000 kcals a day. That is a lot! Just think, there are studies stating that if you cut your calories on a regular basis you will live longer.
