Question about my daily calorie needs

Hi All,

I'm new to this forum and started my weight loss journey this past Sunday. I'm a bit confused about how many calories I actually need per day. My goal reads 1350 per day, but when I click "food" and log my food is says 1931 cals daily. When I started this site, I listed my activity level as "light activity" I walk to work everyday (have been for the past year), the route is 1.8 mi from my home and takes 40 mins each way. Initially I thought this was enough but after gaining 10 pounds I don't think it is. So I've recently added 30-40 min workouts using a Jillian Michael's DVD once per day 6 days a week.

I don't want to overeat and am looking to lose 30 pounds (I'm 5' 5" and 160 pounds). I'm worried that eating the 1931 cals would cause me to gain weight even with the exercises I do. Should I use it as more of a guide? Is there any way I can find out how much I should be eating?

Thanks!!

  • I am not sure, but it may be that your Goal for the day is 1350 and what you actually ate was 1951. In any case 1350 is really low caloric goal, and while it may produce results quickly, the results may not last long.

    If I could give some insight, if you are currently eating 1951 or averaging around this much for you "normal" caloric intake, it may be a better plan of action to reduce this by maybe 100 to 200 cals daily to begin with and see if it has any affect. You want to be able to diet on as many calories as possible in order to lose weight. This way you are able to lose weight without "damaging" your metabolism, which in turn can prevent the "rebound effect" where people fail to keep the weight off, and end up putting all the weight back on, plus more.

    For more information about this topic do a search for metabolic adaptation if you this is something that may be new to you.

    Good Luck!

    Thanks I'll try that! Everytime I logged an exercise my calories went up for some reason.

    Yes, MFP is designed to give you a lower calorie goal than other calculators do with the assumption that you'll log your exercise and eat back some of those extra calories you earn. I'll add a caveat, though. If you're relying on MFP's estimates or a gym machine readout, those tend to overestimate the calories you burn doing certain activities. You may want to eat only 50-75% of the extra exercise calories to account for that.

    Yes - MFP calculated 1350 for you BEFORE exercise. That way people who can't/won't exercise still lose weight. MFP expects you to eat exercise calories back because with out it, you deficit is really large. Think of extra calories as fuel for your workouts.

    HOWEVER.....MFP uses estimates for calorie burns. These estimates are "generous".....so many MFP users will eat a portion back....say 50-75%

    If you eat 1350 and exercise for 600 ....that's like giving your body 750 total calories to work with.....think heart, lungs, kidneys, etc. This is extremely low. Your body can get some fuel from fat....but it can also take it from lean muscle. You need to eat enough to lose "just fat."

    @dianne. Thanks so much! Makes a lot of sense. Will definitely make sure I have leftover calories everyday.

    @teabea thanks! I was initially really confused and afraid to eat over the 1350. Good thing im allowed more food than I thought
