Time of day matters less than a consistent time of day to get your weight change, assuming your eating/workout times are relatively consistent as well.
If you’re trying to show your lowest weight, in the morning after a full night of sleep and prior to eating.
First thing in the morning. Void bladder and bowel (if possible) and weigh. It’s not about weighing at the same time and in the same manner so you see changes, rather than a ‘best time’ really. Consistency is the key to knowing if the scale is moving. However, like you will here on here, please use other methods to track progress as well (ie clothes fitting, picture progress. Etc). Your weight will fluctuate day to day due to water retention levels.
Good luck!
I’m going to be the outlier and say that I’ve always weighed myself close to the end of my fast, after I’ve emptied my bladder. I find that to be the lowest point of the day as I do OMAD and generally fast for 23 hours. If I weight myself first thing in the morning I feel like I’m getting data at the mid point and it’s always higher than if I weigh myself in the evening before dinner. My fasting time is usually 7p-6p or thereabouts, so I’m weighing sometime around 5:30. Someone mentioned it earlier and I’ll second, as long as you’re weighing at the same-ish time every day you’ll establish a baseline to compare to. Weighing in the morning one day and the evening the next will give you invalid data. Consistency on all fronts is key here.
