Across the whole weekend
Share of membersAbout 7 in 10 members (71%) logged more across the weekend than on their weekdays. The rest (29%) logged the same or less.
The spread is wide. The middle half of members ran from about 70 kcal less to about 720 kcal more across the three days.
These are patterns in what members logged, which isn’t always everything they ate. They don’t show why weekends differ.
What this means
About 310 kcal over a weekend is roughly the size of a small meal. Spread over a week it’s modest; it matters most for people already eating close to their target.
What the research says
In a year-long US trial, adults gained weight over weekends, with more eaten on Saturdays; people cutting calories stopped losing weight at weekends.

In US national survey data (2003–2012), Saturday was the least healthy day of the week, with more calories than on weekdays.

Method in brief. UK ParrotPal members’ anonymised food diaries, 1 February to 31 August 2026. Each member is compared with their own typical Monday-to-Thursday day; a counted day has 3 or more entries and 800 to 6,000 kcal, and deleted entries don’t count. Members needed at least 2 counted Fridays, Saturdays and Sundays (over 2,000 UK members).
Aggregates only: every group shown has 50 or more members and no share rests on fewer than 10. Patterns in what members logged, not causes. who’s counted · the 50/10 rule · logged isn’t eaten.
