Tell me please what is the difference between the two expressions. Here is the context:
Additionally, eating eggs has been linked to improved cholesterol levels and weight loss. In one study, women who ate eggs for breakfast, rather than a bagel, reported feeling fuller and ate less later in the day.
Would it have the same meaning if I were to use the word during instead of in? (Source)

Later in the day is more idiomatic there.
The implication is that I will eat this sandwich later in one sitting.
The implication is that I will take a bite or two from this sandwich starting later on and maybe a few more bites again even later.
Later in the day (month, year, season, whatever) refers to a time that falls within the span of the day, whereas during the day refers to a time-span that falls with that span, or to several times falling within that span.
