This isn&amp;#x27;t negligible: in the summer when it&amp;#x27;s hot and I sweat a lot, I can easily drink a 1 liter Nalgene bottle in the morning, about 2 pounds of water. It&amp;#x27;s likely that what you&amp;#x27;ve measured is simply the slow loss of water through perspiration and exhalation throughout the night.&lt;p&gt;I guess technically this &lt;i&gt;is&lt;/i&gt; weight loss because you do weigh less when dehydrated, but it&amp;#x27;s not loss of fat weight, which is what I think most people mean when they say weight loss.&lt;p&gt;Weight fluctuations throughout the day due to water&amp;#x2F;food intake and waste excretion&amp;#x2F;water loss dwarf any actual fat loss, so I don&amp;#x27;t think weighing yourself throughout the day is a viable method of determining when fat weight is lost during the day.</text><parent_chain><item><author>RobertRoberts</author><text>&amp;gt;&amp;quot;Morning weight&amp;quot; == fasted and somewhat dehydrated weight.&lt;p&gt;I was tracking weight loss over time, so it&amp;#x27;s not just water loss. I tracked weight multiple times a day to see when weight loss actually happens.&lt;p&gt;If it was simple dehydration then sleeping would be irrelevant, but sleep is when something is processed, an action occurs that expels the waste&amp;#x2F;water.</text></item><item><author>specialp</author><text>It is more of the effect of not eating or drinking for ~8 hours. 1 pint of water weighs around 500g. Also the average human exhales 1kg of CO2 a day which about a quarter of that is carbon weight.

In a week you&amp;#x27;re not likely to lose more than a &amp;#x27;real&amp;#x27; pound unless you&amp;#x27;re being pretty extreme about your calorie intake or expenditure, but you can fluctuate by easily 5 pounds of water&amp;#x2F;food weight in a day.&lt;p&gt;Source: tracking my calories and weight for the better part of a decade and having lost and kept off 150+lbs.</text><parent_chain><item><author>RobertRoberts</author><text>&amp;gt;&amp;quot;Morning weight&amp;quot; == fasted and somewhat dehydrated weight.&lt;p&gt;I was tracking weight loss over time, so it&amp;#x27;s not just water loss.
