The Saturday rise in food diaries is biggest at 35 to 44 and smallest at 18 to 24
Key findings
UK ParrotPal members aged 35 to 44 logged about 165 kcal more on a Saturday than on their own Monday to Thursday; members aged 18 to 24 about 60 kcal more, February to August 2026. Source: ParrotPal anonymised food diaries.
The weekend rise in food diaries isn’t the same at every age. Members aged 35 to 44 logged about 165 kcal (10%) more on a Saturday than on their own Monday to Thursday. Members aged 18 to 24 logged about 60 kcal (3%) more.

Saturday rise, by age
vs own Mon–ThuThe rise climbs through the twenties and thirties, peaks in the mid-thirties to mid-fifties, and eases again after 55. The 18 to 24 group is the smallest here (about 180 members), so treat its figure with more care.
Women and men showed the same 8% Saturday rise in percentage terms: about 115 kcal for women and about 145 kcal for men, whose typical weekday is larger.
Age bands are what members told us when they joined. These are patterns in what members logged, not why.
What this means
The weekend rise is biggest in mid-life, when weekdays are often most structured. These are averages across groups, not a rule for anyone in them.
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. Every age group shown has at least 50 members, and no share rests on fewer than 10.
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 · rounding.
