How often should you really weigh yourself?

Few topics are more debated in health than the value of the humble bathroom scale. Some experts advocate daily self-weigh-ins to promote accountability for weight management, particularly when we’re following a diet and exercise program to lose weight.

Others suggest ditching self-weigh-ins altogether, arguing they can trigger negative psychological responses and unhealthy behaviours when we don’t like, or understand, the number we see on the scale.

Many, like me, recommend using scales to weigh yourself weekly, even when we’re not trying to lose weight. Here’s why.

1. Weighing weekly helps you manage your weight

Research confirms regular self-weighing is an effective weight loss and management strategy, primarily because it helps increase awareness of our current weight and any changes.

A systematic review of 12 studies found participants who weighed themselves weekly or daily over several months lost 1–3 BMI (body mass index) units more and regained less weight than participants who didn’t weight themselves frequently. The weight-loss benefit was evident with weekly weighing; there was no added benefit with daily weighing.

Self-weigh-ins are an essential tool for weight management as we age. Adults tend to gain weight progressively through middle age. While the average weight gain is typically between 0.5–1kg per year, this modest accumulation of weight can lead to obesity over time. Weekly weighing and keeping track of the results helps avoid unnecessary weight gain.

Tracking our weight can also help identify medical issues early. Dramatic changes in weight can be an early sign of some conditions, including problems with our thyroid, digestion and diabetes.

2. Weekly weighing accounts for normal fluctuations

Our body weight can fluctuate within a single day and across the days of the week. Studies show body weight fluctuates by 0.35% within the week and it’s typically higher after the weekend.

Daily and day-to-day body weight fluctuations have several causes, many linked to our body’s water content. The more common causes include:

The type of food we’ve consumed

When we’ve eaten a dinner higher in carbohydrates, we’ll weigh more the next day. This change is a result of our bodies temporarily carrying more water. We retain 3–4 grams of water per gram of carbohydrate consumed to store the energy we take from carbs.

Our water content also increases when we consume foods higher in salt. Our bodies try to maintain a balance of sodium and water. When the concentration of salt in our bloodstream increases, a mechanism is triggered to restore balance by retaining water to dilute the excess salt.

Our food intake

Whether it’s 30 grams of nuts or 65 grams of lean meat, everything we eat and drink has weight, which increases our body weight temporarily while we digest and metabolise what we’ve consumed.

Our weight also tends to be lower first thing in the morning after our food intake has been restricted overnight and higher in the evening after our daily intake of food and drinks.

Exercise

If we weigh ourselves at the gym after a workout, there’s a good chance we’ll weigh less due to sweat-induced fluid loss. The amount of water lost varies depending on things like our workout intensity and duration, the temperature and humidity, along with our sweat rate and hydration level. On average, we lose 1 litre of sweat during an hour of moderate-intensity exercise.

Hormonal changes

Fluctuations in hormones within your menstrual cycle can also affect fluid balance. Women may experience fluid retention and temporarily gain 0.5–2kg of weight at this time. Specifically, the luteal phase, which represents the second half of a woman’s cycle, results in a shift of fluid from your blood plasma to your cells, and bloating.

Bowel movements

Going to the bathroom can lead to small but immediate weight loss as waste is eliminated from the body. While the amount lost will vary, we generally eliminate around 100 grams of weight through our daily bowel movements.

All of these fluctuations are normal, and they’re not indicative of significant changes in our body fat or muscle mass. However, seeing these fluctuations can lead to unnecessary stress and a fixation with our weight.

3. Weekly weighing avoids scale obsession and weight-loss sabotage

Weighing too frequently can create an obsession with the number on the scales and do more harm than good.

Often, our reaction when we see this number not moving in the direction we want or expect is to further restrict our food intake or embark on fad dieting. Along with not being enjoyable or sustainable, fad diets also ultimately increase our weight gain rather than reversing it.

This was confirmed in a long-term study comparing intentional weight loss among more than 4,000 twins. The researchers found the likelihood of becoming overweight by the age of 25 was significantly greater for a twin who dieted to lose 5kg or more. This suggests frequent dieting makes us more susceptible to weight gain and prone to future weight gain.

So what should you do?

Weighing ourselves weekly gives a more accurate measure of our weight trends over time.

Aim to weigh yourself on the same day, at the same time and in the same environment each week – for example, first thing every Friday morning when you’re getting ready to take a shower, after you’ve gone to the bathroom, but before you’ve drunk or eaten anything.

Use the best quality scales you can afford. Change the batteries regularly and check their accuracy by using a “known” weight – for example, a 10kg weight plate. Place the “known” weight on the scale and check the measurement aligns with the “known” weight.

Remember, the number on the scale is just one part of health and weight management. Focusing solely on it can overshadow other indicators, such as how your clothes fit. It’s also essential to pay equal attention to how we’re feeling, physically and emotionally.

Stop weighing yourself – at any time interval – if it’s triggering anxiety or stress, and get in touch with a health-care professional to discuss this.

  • If Your Adult Kid Calls In Crisis…

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Parent(s) To The Rescue?

    We’ve written before about the very common (yes, really, it is common) phenomenon of estrangement between parents and adult children:

    Family Estrangement & How To Fix It

    We’ve also written about the juggling act that can be…

    Managing Sibling Relationships In Adult Life

    …which includes dealing with such situations as supporting each other through difficult times, while still maintaining healthy boundaries.

    But what about when one’s [adult] child is in crisis?

    When a parent’s job never ends

    Hopefully, we have not been estranged (or worse, bereaved) by our children.

    In which case, when crisis hits, we are likely to be amongst the first to whom our children will reach out for support. Naturally, we will want to help. But how can we do that, and where (if applicable) to draw the line?

    No “helicopter parenting”

    If you’ve not heard the term “helicopter parenting”, it refers to the sort of parents who hover around, waiting to swoop in at a moment’s notice.

    This is most often applied to parents of kids of university age and downwards, but it’s worth keeping it in mind at any age.

    After all, we do want our kids to be able to solve their own problems if possible!

    So, if you’ve ever advised your kid to “take a deep breath and count to 10” (or even if you haven’t), then, consider doing that too, and then…

    Listen first!

    If your first reaction isn’t to join them in panic, it might be to groan and “oh not again”. But for now, quietly shelve that, and listen to whatever it is.

    See also: Active Listening (Without Sounding Like A Furby)

    And certainly, do your best to maintain your own calm while listening. Your kid is in all likelihood looking to you to be the rock in the storm, so let’s be that.

    Empower them, if you can

    Maybe they just needed to vent. If so, the above will probably cover it.

    More likely, they need help.

    Perhaps they need guidance, from your greater life experience. Sometimes things that can seem like overwhelming challenges to one person, are a thing we dealt with 20 or more years ago (it probably felt overwhelming to us at the time, too, but here we are, the other side of it).

    Tip: ask “are you looking for my guidance/advice/etc?” before offering it. Doing so will make it much more likely to be accepted rather than rejected as unsolicited advice.

    Chances are, they will take the life-ring offered.

    It could be that that’s not what they had in mind, and they’re looking for material support. If so…

    When it’s about money or similar

    Tip: it’s worth thinking about this sort of thing in advance (now is great, if you have adult kids), and ask yourself nowwhat you’d be prepared to give in that regard, e.g:

    • if they need money, how much (if any) are you willing and able to provide?
    • if they want/need to come stay with you, how prepared are you for that (including: if they want/need to actually move back in with you for a while, which is increasingly common these days)?

    Having these answers in your head ready will make the conversation a lot less difficult in the moment, and will avoid you giving a knee-jerk response you might regret (in either direction).

    Have a counteroffer up your sleeve if necessary

    Maybe:

    • you can’t solve their life problem for them, but you can help them find a therapist (if applicable, for example)
    • you can’t solve their money problem for them, but you can help them find a free debt advice service (if applicable, for example)
    • you can’t solve their residence problem for them, but you can help them find a service that can help with that (if applicable, for example)

    You don’t need to brainstorm now for every option; you’re a parent, not Batman. But it’s a lot easier to think through such hypothetical thought-experiments now, than it will be with your fraught kid on the phone later.

    Magic words to remember: “Let’s find a way through this for you”

    Don’t forget to look after yourself

    Many of us, as parents, will tend to not think twice before sacrificing something for our kid(s). That’s generally laudable, but we must avoid accidentally becoming “the giving tree” who has nothing left for ourself, and that includes our mental energy and our personal peace.

    That doesn’t mean that when your kid comes in crisis we say “Shh, stop disturbing my personal peace”, but it does mean that we remember to keep at least some boundaries (also figure out now what they are, too!), and to take care of ourselves too.

    The following article was written with a slightly different scenario in mind, but the advice remains just as valid here:

    Based heavily in hard science, with more than 450 citations in over 300 pages, the exhortation is not just “trust me, lol”.

    Instead, she encourages the reader to experiment. Not like “try this and see if it works”, but “here’s how to try this, using scientific method with good controls and good record-keeping”.

    The book is divided into sections, each with a projection of time required at the start and a summary at the end. The reading style is easy-reading throughout, without sacrificing substance.

    It proposes seven key interventions. If just one works for you, it’ll be worth having bought and read the book. More likely most if not all will… Because that’s how science works.

  • Atomic Habits – by James Clear

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    James Clear’s Atomic Habits has become “the” go-to book about the power of habit-forming. And, there’s no shortage of competition out there, so that’s quite a statement. What makes this book stand out?

    A lot of books start by assuming you want to build habits. That can seem a fair assumption; after all, we picked up the book! But an introductory chapter really hammers home the idea in a way that makes it a lot more motivational:

    • Habits are the compound interest of productivity
    • This means that progress is not linear, but exponential
    • Habits can also be stacked, and thus become synergistic
    • The more positive habits you add incrementally, the easier they become because each thing is making your life easier/better

    For example:

    • It’s easier to save money if you’re in good health
    • It’s easier to sleep better if you do not have financial worries
    • It’s easier to build your relationship with your loved ones if you’re not tired

    …and so on.

    For many people this presents a Catch-22 problem! Clear instead presents it as an opportunity… Start wherever you like, but just start small, with some two-minute thing, and build from there.

    A lot of the book is given over to:

    • how to form effective habits (using his “Four Laws”)
    • how to build them into your life
    • how to handle mishaps
    • how to make sure your habits are working for you
    • how to see habits as part of your identity, and not just a goal to be checked off

    The last one is perhaps key—goals cease to be motivating once accomplished. Habits, on the other hand, keep spiralling upwards (if you guide them appropriately).

    There’s lots more we could say, but it’s a one-minute book review, so we’ll just close by saying:

    This book can help you to become the kind of person who genuinely gets a little better each day, and reaps the benefits over time.

  • Dried Apricots vs Dried Prunes – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing dried apricots to dried prunes, we picked the prunes.

    Why?

    First, let’s talk hydration. We’ve described both of these as “dried”, but prunes are by default dried plums, usually partially rehydrated. So, for fairness, on the other side of things we’re also looking at dried apricots, partially rehydrated. Otherwise, it would look (mass for mass or volume for volume) like one is seriously outstripping the other even if some metric were actually equal, just because of water-weight in one and not the other.

    Illustrative example: consider, for example, that the sugar in a bunch of grapes or a handful of raisins can be the same, not because they magically got more sugary, but because the water was dried out, so per mass and per volume, there’s more sugar, proportionally.

    Back to dried apricots and dried prunes…

    You’ll often see these two next to each other in the heath food store, which is why we’re comparing them here.

    Of course, if it is practical, please by all means enjoy fresh apricots and fresh plums. But we know that life is not always convenient, fruits are not in season growing in abundance in our gardens all year round, and sometimes we’re stood in the aisle of a grocery store, weighing up the dried fruit options. 

    • Apricots are well-known for their zinc, potassium, and vitamin A.
    • Prunes are well-known for their fiber.

    But that’s not the whole story…

    • Apricots outperform prunes for vitamin A, and also vitamins C and E.
    • Prunes take first place for vitamins B1, B2, B3, B5, B6, and K, and also for minerals calcium, copper, iron, magnesium, manganese, phosphorus, potassium, sodium, and zinc.
    • Prunes also have about 3x the fiber, which at the very least offsets the fact that they have 3x the sugar.

    Once again, sugar in fruit is healthy (sugar in fruit juices is not*, though, so enjoy prunes rather than just prune juice, if you can) and can take its rightful place as providing a significant portion of our daily energy needs, if we let it.

    *It’s the same sugar, just the manner of delivery changes what it does to our liver and our pancreas; see:

    Which Sugars Are Healthier, And Which Are Just The Same?

    In summary…

    Dried apricots are great (fresh are even better), and yet prunes outperform them by most metrics on a like-for-like basis.

    Prunes have, on balance, a lot more vitamins and minerals, as well as more fiber and energy.

  • Falling: Is It Due To Age Or Health Issues?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    It’s Q&A Day at 10almonds!

    Have a question or a request? We love to hear from you!

    In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

    As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

    So, no question/request too big or small 😎

    ❝What are the signs that a senior is falling due to health issues rather than just aging?❞

    Superficial answer: having an ear infection can result in a loss of balance, and is not particularly tied to age as a risk factor

    More useful answer: first, let’s consider these two true statements:

    • The risks of falling (both the probability and the severity of consequences) increase with age
    • Health issues (in general) tend to increase with age

    With this in mind, it’s difficult to disconnect the two, as neither exist in a vacuum, and each is strongly associated with the other.

    So the question is easier to answer by first flipping it, to ask:

    ❝What are the health issues that typically increase with age, that increase the chances of falling?❞

    A non-exhaustive list includes:

    • Loss of strength due to sarcopenia (reduced muscle mass)
    • Loss of mobility due to increased stiffness (many causes, most of which worsen with age)
    • Loss of risk-awareness due to diminished senses (for example, not seeing an obstacle until too late)
    • Loss of risk-awareness due to reduced mental focus (cognitive decline producing absent-mindedness)

    Note that in the last example there, and to a lesser extent the third one, reminds us that falls also often do not happen in a vacuum. There is (despite how it may sometimes feel!) no actual change in our physical relationship with gravity as we get older; most falls are about falling over things, even if it’s just one’s own feet:

    The 4 Bad Habits That Cause The Most Falls While Walking

    Disclaimer: sometimes a person may just fall down for no external reason. An example of why this may happen is if a person’s joint (for example an ankle or a knee) has a particular weakness that means it’ll occasionally just buckle and collapse under one’s own weight. This doesn’t even have to be a lot of weight! The weakness could be due to an old injury, or Ehlers-Danlos Syndrome (with its characteristic joint hypermobility symptoms), or something else entirely.

    Now, notice how:

    • all of these things can happen at any age
    • all of these things are more likely to happen the older we get
    • none of these things have to happen at any age

    That last one’s important to remember! Aging is often viewed as an implacable Behemoth, but the truth is that it is many-faceted and every single one of those facets can be countered, to a greater or lesser degree.

    Think of a room full of 80-year-olds, and now imagine that…

    • One has the hearing of a 20-year-old
    • One has the eyesight of a 20-year-old
    • One has the sharp quick mind of a 20-year-old
    • One has the cardiovascular fitness of a 20-year-old

    …etc. Now, none of those things in isolation is unthinkable, so remember, there is no magic law of the universe saying we can’t have each of them:

    Age & Aging: What Can (And Can’t) We Do About It?

    Which means: that goes for the things that increase the risk of falling, too. In other words, we can combat sarcopenia with protein and resistance training, maintain our mobility, look after our sensory organs as best we can, nourish our brain and keep it sharp, etc etc etc:

    Train For The Event Of Your Life! (Mobility As A Long-Term “Athletic” Goal For Personal Safety)

    Which doesn’t mean: that we will necessarily succeed in all areas. Your writer here, broadly in excellent health, and whose lower body is still a veritable powerhouse in athletic terms, has a right ankle and left knee that will sometimes just buckle (yay, the aforementioned hypermobility).

    So, it becomes a priority to pre-empt the consequences of that, for example:

    • being able to fall with minimal impact (this is a matter of knowing how, and can be learned from “soft” martial arts such as aikido), and
    • ensuring the skeleton can take a knock if necessary (keeping a good balance of vitamins, minerals, protein, etc; keeping an eye on bone density).
