For this blog post I weighed myself first thing every morning, before eating and after using the toilet for a week.
Before I started I took my weight on the Sunday evening before bed.
Sunday 26th 11.45pm – 90.5kg
This was at the end of a full day of eating, not using the toilet to “evacuate” and about an hour after some takeaway pizza
Monday 27th 8am – 89.9kg
Today I ate a 1000 calories brunch (pictured below), drank over 3 litres of water and in the evening, due to a very upset baby I didnt have a second meal. Opting for 2 cookies and a glass of milk wouldnt be recommended but when tired and stressed it was an easy option.

Funnily enough I also weighed in fully clothed at 9.20am and even after using the toilet the scale read 92kg. A 2.1kg increase from 80 minutes earlier. Was I fatter? No.
Tues at 5.45am – 89.2kg
A 0.7kg drop from day 1 and I put this down to simply not eating a lot on Monday.
Stomach contents were lower and I used the toilet yesterday too. Dont forget that you sweat at night too and may lose water weight that returns to the scale once you drink again.
At the time of writing this paragraph it is 10.45pm and I have just woken up from falling asleep on the sofa with Eve on my chest. Sarah has ordered a pizza and I have eaten 2 slices and some wedges. I’m expecting my weight to increase in the morning due to the volume of food and water retention*.
*Carbs hold 3-4ml of water per gram and I ate a lot of carbs today.
Weds at 6.30am – 88.9kg
Honestly expected my scale weight to be up this morning after eating the pizza late last night with a 500ml bottle of water. It goes to show that scale weight can be deceiving.
Down 1.6kg since Sunday evenings weigh-in and that hasn’t been my intention at all.
Thurs at 5.45am – 90kg
Up 1.1kg from yesterday morning. No major increases in total food volume, carbs or fluid intake. Your guess is as good as mine. I’ll weigh in after my shower once home from work to see if there is any change.
Thurs at 5pm – 90kg
No change from this morning. I’m damp from the shower. Does that matter? No. Sticking with the full week before I make any judgements or conclusions.
Fri at 6.45am – 88.9kg
Back to the same weight as I was at Wednesday. The more I weigh myself, the less the fluctuations make sense!
Sat at 9.45am – 88.8kg
A hectic day yesterday (Friday) meant my food intake was poor and well below what I would normally eat. A bowl of cheerios and a ham, cheese and salad sambo kept me going between doctor and hospital appointments and correcting 25 assignments that took me 6 hours start to finish. My hydration was also way off. I drank 1.5l at best! Half of what I normally drink.
Today (Saturday) started much better with 3 eggs, black pudding, 4 strips of bacon and 2 pancakes for breakfast. I expect my scale weight to be up again tomorrow.
Sunday at 10.30am – 88.4kg
I weighed in later at the weekend but still made sure it was after using the bathroom and before I ate or drank.
All weigh ins took place in my underwear in my upstairs bathroom every morning. I use the toilet every morning after waking and the scale and pen are in the bathroom to record it. I stacked one habit (weighing) on top of another (peeing).
This is a great way to make new habits more consistent. Pair them with one you already do consistently! Anyway, that’s a whole other post.
If you are using scale weight as a marker of progress I strongly advise you to Weigh-in every morning and use a weekly average to track long term progress.
This way you aren’t at the whim of fluctuations because of stomach contents after a large meal, water retention during your period or simply being well hydrated along with muscle glycogen stored being full, although the effect of this on scale weight is minimal.
Here are my own stats from the week:
Weight on Sunday Night = 90.5kg
Heaviest Weight = 90kg
Lightest Weight = 88.4kg
Weekly Average = 88.9kg
That’s an average loss of 0.8kg/1.76lbs for the week.
However if I weighed in on Monday (89.9kg) and Thursday (90kg) only I’d be forgiven for thinking that “it’s not working”.
Scale weight is only 1 piece of data to track progress. It is a guide and will fluctuate due to a whole host of biological, environmental and physiological reasons.
Am I happy with the results?
Sure!
My aim is to maintain my current weight because I know that tiredness and a hectic work and home life can lead to poor food choices and the inevitable weight gain. If I can maintain until our newborn sleeps a bit better then I can dedicate more time to my own training and goals.
If you weigh each week in a slimming club or even at home then I urge you do do it as early as possible under the same circumstances each week to get the most consistent result possible.
Weighing in on Tuesday at 9am one week and 7pm the next when fully hydrated with a full belly too will have you up 2lbs and your leader giving you the lip.
Put the scale in the bathroom, grab a pen and sheet of paper and stick them to the wall and post your results in my private Facebook Group at any time.
If you enjoyed reading this and you want to school a weekly weigher then please share this post with your friends and enemies. I would really appreciate it.
