Why am I losing weight?

For the past 6 weeks I have pretty much been eating at maintenance or above but have still managed to lose around 3 pounds during that time. Anyone have any thoughts other than natural fluctuations?

    If you're certain that your food weights are accurate, perhaps consider consulting your physician to make sure you don't have a medical issue causing the weight loss. I wouldn't suggest this for a week or two's worth, but six weeks at a steady drop when you know you're eating at or above maintenance might be some fluctuation or inaccurate entries, but if it continues over the next couple of weeks, I would see my doctor if it were me just to rule out anything that might need medical attention.

    Depends on how you're calculating the 3 pounds, is it one weigh in of 3 pounds loss in 3 weeks or a number of weigh ins over the same period.

    If it's a number of weigh ins over the 6 weeks maybe you're not actually at maintenance, it's all averages and it would be easy to underestimate exercise and activity/overestimate food enough to be out by 250 cals per day which is all it would take.

    If it's a one off weigh in then yes it's also in the realms of a normal water weight fluctuation.

    Just monitor and adjust as necessary

    It's based on daily weigh ins using Libra

    These numbers are all best estimates, so maybe your maintenance is a little higher than you think. If the trend keeps up and you are trying to maintain bump your calories up accordingly.

    I realise it's all estimates but this experience for me is showing a minimum of 15% discrepancy which is not very accurate.

    If you're using Libra, look at the rate in the bottom box and it will tell you an approximate calorie deficit using your real world results. Just add in an extra snack to that amount to your day.

    3lbs over 6 weeks really isn't a ton. More than likely, you maintenance level is slighter higher. TDEE is a calculation, and while pretty accurate, the body doesn't burn calories like a perfect math equation, some times it does require a little tweaking for the individual. I would try adding 200-300 calories per day and then play with the numbers more from there as needed.

    Sounds like you are eating below maintenance.

    You're not going to exactly back into your maintenance calories by taking your weight loss calories and adding back the caloric equivalent of your average weight of loss. That's only going to give you an estimate. Once you start eating more, your body burns more calories due to needing to digest that food and you are going to move more without even thinking about it. It's pretty normal for those things to add 100-200 or so calories to your TDEE.

    Actually due to certain circumstances I have actually been a lot more sedentary during that period than normal.

    If anyone suggested that eating more would mean that you burn more in a post about not losing weight they would be laughed off this forum :tongue:

    If you look at studies on the issue of energy burned (don't have links handy), it's not at all out of the question that you might burn 10-15% more than you think. There are too many variables for estimates to actually be calculations. I'm sure a population bell curve would put the calories burned of 70% of the population within about 5% of the mean and 95% within 10% of the mean. Of course, there would be outliers that could range higher. (Note these numbers are for illustration - I can't remember what the studies' variations were).

    The only accuracy you really have is your best estimates of intake, your best estimates of burned calories, and a long term relationship between your numbers and the scale. You can (somewhat) control the intake accuracy, (somewhat less) control the burn accuracy, and then just tweak over long term variations.

    I'd suggest that's entirely not true. As long as it is put into appropriate context

    Not going to trawl through that but pretty sure noone there suggested eating more would mean you burn more, and I know we do but only by a matter of a 20/30 calories on the figures I am talking about.

    Eating extra calories will never cause you to burn more than those extra calories though!!!! I'm eating around an extra 300 calories even with the extra burn from digestion that is still wiping out my deficit

    Nobody is saying it does. I'm saying you're burning and extra 30 or so calories just by eating 300 more calories than you were 7 weeks ago. Your NEAT very likely has gone up at least a bit without you realizing it. So perhaps your total calorie burn has increased by 125. Between that and the fact that delayed weight loss is as much a reality as delayed weight loss (i.e., weight loss is not linear, short stalls are normal), you're down a few pounds.

    Several hundred calories or more a day

    Just to be clear/complete... it sounds like there are 2 slightly different themes to the responses here.
    1. Eat more... magic happens... scale starts moving again
    2. Eat more... feel better, move more, adhere better, deficit better... scale starts moving

    The first one is a thing, but not for most people. There's a good thread going about refeeds - look it up if you think this scenario applies to you. The hugely oversimplified cliff notes is that if you maintaining a big enough deficit for long enough, your body/hormones adapt and what was a deficit no longer is. Eating more can help "reset" things.

    The second scenario is the case for far more people. They maintain a deficit, lose some weight, then plateau. That plateau could happen for a number of reasons... because they get lazy with their logging/tracking, they get lazy with their workouts, they are moving less in general (NEAT), simply don't have the drive they did when they started out, etc etc. In this case, eating more can help with some of those "symptoms"... and the trickle down effect of eating more is a more consistent deficit which means weight loss... but that only happens IF those symptoms are aleviated. If you eat more but continue to be lazy, unmotivated, sloppy with your logging, etc etc, you won't see any improvement in weight loss.


    The vast majority of people should assume they fall into #2. Because they probably do.

    Really no need to trawl through, you could have just flipped to the last page and read a couple comments.
