Exercise more, eat more..???

Hi,

I'm new to all this and wonder if someone could please advise me?

My daily calorie goal is 1300..

Now, usually I exercise on bike for 30 minutes which burns approx 240 cals. I usually do this twice a day, every day. So when I log this on MFP it tells me that I have "earned an extra 480 cals from exercise".

Does this mean that I am supposed to eat extra?

I have a couple of different friends who are giving me conflicting advice. :huh:

Friend 'A' says that I am supposed to eat my daily calorie amount (1300) PLUS the amount that I burn through exercise otherwise I will not lose any weight..

Friend 'B' says that I should only eat my daily calorie amount (1300) and that anything that I burn through exercise should not be eaten because I will NOT lose.

Friend 'B' also says that if I eat my daily calorie goal (1300) and don't exercise at all on that day then this is fine too.

Any pointers or advice would be great and hugely appreciated :smile:

Thanks

    yes.
    How much? The whole amount that I burned or just 'up' to that amount..??
    Thanks

    Friend A is right, friend be is wrong. MFP sets up your deficit assuming you will NOT exercise. When you add in exercise it make your deficit to big, so you eat more food to fuel you body. However, depending on how you calculate you calories burned makes a difference on how many you eat back. MFP tends to over estimate calories burned, so eat back 50%-75%. If you use a HRM monitor, you can probably get by with eating 75%+ back.

    it's a goal. when you burn that much, MFP is still taking into account that you're going to be at a calorie deficit. Eat at least a portion of it back.

    Your activity level is not supposed to account for deliberate exercise with MFP...just your day to day stuff...wouldn't it be logical that you would have to account for exercise somewhere in the equation? Here's how the very basic math looks.

    Without exercise I can maintain on 2350 calories...so to lose 1 Lb per week MFP would knock off 500 calories from there and give me a non-exercise calorie goal of 1,850 calories (2,350 - 500 = 1,850).

    Now I decide that exercise is really good for me, but that activity is not accounted for in the equation above and I don't really like the idea of under-nourishing my body...so I log that EXTRA activity that is not already included in my activity level...let's say that it's 400 calories...so now my MFP calorie goal goes from 1,850 to 2,250 ( 1,850 + 400 = 2,250) but I still have that 500 calorie deficit because my non-exercise maintenance number has also increased by those same 400 calories...so, 2,350 + 400 = 2,750 calories and 2,750 - 2,250 = 500 calorie deficit still.

    You'll want to make sure you're estimating your burns as accurately as possible...don't just take some number in a database as gospel...they are generally overstated. Do some kind of reasonableness test...I always used my HRM for a cardio workout and deducted about 20% of what my HRM told me I burned...then I'd compare that to my perceived level of effort with 10 calories per minute basically being my max as it is difficult to burn more than that over a sustained period of time. Basically a good 10 calorie per minute burn would be an exercise for which I could not really hold a conversation while I was working out...a 5 calorie per minute burn would basically be moderate to slow paced walk and then everything in between.

    Be prepared, the friend in the wrong may not accept the correction.

    Yes, eat your exercise calories, if you know that the 240 estimate is reasonably accurate. Food is fuel. MFP has set a deficit for you without exercise, so that some of your fuel will come from stored fat. But when you exercise, you need more fuel, and you don't want to draw down fat stores too quickly.

    For more detail, see this post from the Eat, Train, Progress forum:

    I rarely eat back the full amount. I think of it more like, using MFP's calculations I will lose 1 lb per week minimum. If I can lose more, great. If not, no big deal. I don't believe in strictly keeping it close to 0 every day. The amount you chose to lose was arbitrary anyway. If I had chosen 1.5 lb or 2 lb instead of 1lb, I would be eating less anyway.

    It's not as arbitrary for people who have less weight to lose, a bigger calorie deficit isn't recommended for them. A person who is closer to goal weight who chooses 2 pounds a week can be at an already too large calorie deficit, so then not eating more for exercise can be harmful.

    Many of the "estimates" of online calculators tend to overestimate exercise and over estimate RMR/BMR/TDEE. IMHO I would be conservative and use as many measurable numbers as possible. I had my RMR tested, I have a HRM to track cardio burns, I weigh and measure all foods and keep a similar diet from week to week to see the impact. I do not eat back calories, I do not give myself a daily activity factor, or give myself caloric credits for weight training. My formula is simple and I spreadsheet it to set weight loss goals for the week.

    (Tested RMR + measurable cardio burns - Calories consumed= deficit)

    I then compare my weekly deficit to the 3500 calories deficit= 1 lb. loss. I am usually losing more than the "chart". Not surprising, because I have eliminated the estimates. I also focus on creating deficits and not eating.

    Everyone says you're supposed to eat them back but if you don't, then you'll lose almost an extra pound of fat per week. I usually don't eat them back unless I'm hungry. If you do eat them back, you'll still lose but way less.

    This largely depends on your fat stores. I'm at a healthy BF% but could stand to knock off a couple more cosmetic points...but too large a deficit would only cause me to burn up a lot of muscle mass. Not to mention that some of my exercise can be pretty intense and really breaks my body down...to rebuild my body requires proper fueling and energy...If I were to just eat my 2500 calories or so to lose 1/2 Lb per week and then go on a good 30 mile ride, that would net me around 1300 calories and would not be nearly enough to aid in recovery of said ride. On such days I make sure that I am eating around 3500 calories or so.

    Thank you, I was recently asked this & I had to sit down & think about it.

    if you go below 1200 with exercise you NEED to eat them back, unless you want to loose hair nails bones muscle tissue and some actual fat on the side.

    Nope, you broke it. The body can lose up to 2 pounds a week of fat without losing muscle. It's like nobody on this site actually wants to lose weight.

    Hi. I need some help. I tried to open up my own post but I must be blind because I can't find the "new post" tab.

    Anyways, I am 5'6' 144 lbs 24 yr old female who is currently unhappy with physical appearance of body and I want to get down to 120 lbs.

    I am currently eating 1200 calories and working out 6 days a week burning 400 calories per exercise (i do treadmill -walk very briskly/jog/run). I also eat back 3/4 to all of my calories that I burn during exercise.

    Can someone tell me how long it will take me to get to my goal? Or if I am on the right track? I still eat one cheat food a day like a twinkie or a cookie? or a cup of coffee with 1 sugar 1 cream in it. I drink like 10-12 glasses of water daily as well.

    Funny. I'm losing weight just fine eating back most (not all) of my exercise calories. Might I lose faster if I didn't? No, because before I'd start eating anything that didn't try to get away from me, possibly including furniture.
