I know I'm probably going to sound completely stupid, but in no way am I a nutritionist or anything like that so can somebody explain the logic of weight loss..

If my BMR is 1400 and I exercise and burnt off 500 calories
How many calories essentially would I need to be under to lose weight?

I am just having a blonde, very confused moment...

    you need to work out your TDEE, not your BMR.

    Have a look here -

    use the fitness frog website to work out tdee that takes into account all your exercise and tell what your maintenence calories are then all you need to do is take 20% off and eat the remaining 80% calories.

    Your tdee would be around 2180 assuming you are sedentary otherwise. From 2180 take 80% and it would leave you 1744. Wo a goal would be 1750 calories and then adjust macros to improve muscle retention.

    Eating a bit over BMI is always a good idea to make sure you get enough nutrition, but the exact TDEE varies based on how much exercise you do use the 10% over BMI as a baseline for how much you should eat if in doubt... Adjust up if hungry and have worked out a lot... If BMI is 1400 then 1540 calories should probably do the trick for you for a quicker weight loss... 20% over would be 1680... You need to figure that out based on how active you are and how fast you want to lose the weight!

    Charli, you would need to at your BMR of 1400 after you 500 cal burn. The idea on MFP is not to eat less than your BMR. So do not eat lower than the 1400 cals even after exercise

    What helped me when I was first starting with the whole weight loss thing is following MFP guide lines and I am sure it has helped many other people too.

    Stick with those rules and you can look into other `things` as you move along x

    BMR - Basal Metabolic Rate...the rate at which your body burns calories just being alive and not even twitching a muscle. Calories burn by you breathing...heart pumping, etc

    NEAT - Non Exercise Activity Thermogenesis. This is what MFP uses in determining your calorie goal. Essentially, your BMR + the calories you burn during your day to day activity from getting out of bed, taking a pisser, brushing your teeth, sitting at your desk and typing on MFP, etc. It is everything EXCEPT exercise. Exercise is extra which is why MFP would have you eat back exercise calories using their method.

    TDEE - Total Daily Energy Expenditure. Essentially, BMR+NEAT+Exercise = TDEE. This is everything.

    Using the TDEE method, your caloric intake is TDEE - xx% to be between your BMR and TDEE. Using the MFP method, they knock off xxx calories from your NEAT based on the goals you set to create your deficit.

    The problem is that for many, their weight loss goal drops them well below their BMR. Consistently eating substantially below your BMR can cause lots of problems down the road. I'm not talking about just a couple calories or occasionally going under...I'm talking about people doing 1,200 calorie plans and not eating exercise calories back, thus netting 600 calories or something when their BMR is 1,400.

    Thank you for your replies that has helped a lot,

    So my TDEE is 2100.

    If I had eaten 2000 calories, and exercised 500 calories off. And taken my BMR of 1400 aswell,
    That would be my net calories?

    I am horrible with math, and on this site you will see many people talking about numbers, percentages, stats, estimates, etc. As soon as I see numbers and technical stuff, I blank out. I just cannot process those kinds of conversations. I can't seem to follow it.
    I just follow what MFP tells me. If you plug in all your information, it will tell you how many calories to eat, which is 20% or so less than your TDEE..which MFP will figure for you.

    If you are mathematically inclined, there are tons of people who can answer it more in depth for you, but really, you can just do what MFP tells you to lol
