Can anybody recommend a very accurate scale?

Before you get another set - have you tried different locations in the house? Even a slightly uneven floor can affect the reading ie it’s better to put them on a flat uncarpeted floor. I know my scales will vary so I use exactly the same bit of floor for consistency.

I'm with the VA and got this scale from them. It's currently only $19.99 on Amazon:

Some scales have technology so that you will not get different readings when you step back on it. I have no idea how that works. I think this might be one of them, because on the rare occasion I step back on after my initial morning weigh, I always get the identical result.

I've had it since 2016 and am happy with it.

When I'm weighed at the doctor's after breakfast and dressed I'm the predictable 4-5 pounds heavier.

What you want is to observe the trend over time, which requires patience, which can be intensely frustrating.

Your actual weight can fluctuate by quite a lot due to water retention, hormones, etc, so when you start a new eating plan or exercise regimen it makes sense to stick with it for a month-ish so you can actually tell if it's working or not. I weigh once a week under the same conditions, usually stepping on the scale twice (which might be a mind trick but I tell myself it's better that way). Some people weigh every day and use an app to tell them the trend. I might do that eventually as I get closer to goal weight but I'm happy with how I do things now. Some weeks the scale only drops a little. Other weeks it drops a lot. I log my food accurately and am honest about exercise. When I look at the trend over time, it's what I expect it to be, even if the individual data points are not.

I do tape measurements also every other week. Usually only one or two of the measurements will change and often it's not by much, maybe a quarter of an inch or so. But I can compare me now to me in March or the beginning of the year and I can see how several things have changed. I can also tell by the fact that I have clothes that are now too large (and I take regular progress photos too.) I don't measure just my waist - I actually do my neck, upper arm, forearm, wrist, chest, waist, hips, thigh, calf, and ankle. I use a flexible measuring tape - mine came with a sewing kit I owned already, but they are easy to find. Not everyone experiences this but I seem to be losing weight from the outside in. I didn't think I had exceptionally large ankles or wrists before but they're skinnier than they used to be!

Weight loss is a marathon, not a sprint. The nice thing is, if you do it well you're learning the same skills you need to maintain the loss afterwards.

That is a lot of variability if you are getting on and off your scale in rapid succession. When was the last time you changed the batteries? Are the scales feet level and unbroken with no dust around them? Are you weighing at the same time of the day in the same clothes (in the morning after using the bathroom, e.g.)? Are your feet dry and not lotioned?

I don't believe that there is an entirely accurate scale but if you lessen the variables your scale will show a consistent trend over time. I weigh daily, in the morning after using the bathroom in the same clothes, on the same spot. I also take measurements monthly(bust, waist, hips, thighs, calves, biceps) once a month and take progress pictures at 20 pound intervals.

The scale is just one tool of many you can use to measure progress. I went a month with no weight changes once but measurements showed that I lost 3 inches from each thigh. I never would have known if I only relied on the scale.

@vaindioux to answer your question about how you know if you are losing: it’s always a good idea to track your weight loss in different ways (to help combat things like water weight and fluctuating scales). So weigh yourself regularly (weekly or daily), record that on a spreadsheet or MFP so that you’ve can track and start to recognise normal fluctuations (water retention at times of the months etc). Also take measurements with a tape measure and record them - they can often show you progress more than the scale. Take pictures, front, back and sides and again keep a record so that you can see your progress. You can also track loss using how your clothes fit and how easy you find certain activities. Using all of those methods can help you 👍

The scale I got last month from the VA is made by the A&D Medical company. The model I have doesn't look like it's available to the general public, however A&D does have a similar style home model available for $69.99 on Amazon (link below). What I really like about these scales is they're accuracy is certified through the Continua Certified program and the ease of use. You just step on it, wait for the beep and hold until you get the notification to step off, then it displays your weight. I weigh myself daily and watch the overall trend. The bluetooth works fine to send data to the tablet the VA provided. Looks like the negative reviews have to do with bluetooth connection issues to Samsung phones, not the accuracy of the scale.

My weight has always, by function of being alive, bounced around a few pounds. All that actually happens is that the highs and lows eventually both get lower.

Less frequent weighing may help your brain.
