Tuesday Crowned Healthiest Eating Day in Simple Life App's 30 million-meal Analysis

Data from Simple Life App Uncovers Weekly Nutrition Patterns in more than 700,000 Users

ORLANDO, Fla., June 4, 2025 /PRNewswire/ -- New research from Simple Life, an AI-powered health coaching and weight loss app, reveals a surprising trend in how Americans eat: people are most likely to make healthy food choices on Tuesdays, while weekends remain the most nutritionally challenging.

Presented at Nutrition 2025, the study analyzed over 34 million meals logged by more than 777,000 users, 77.5% of whom were women. The data showed that Tuesdays had the highest nutritional quality, with the largest proportion of meals rated Optimal via Simple's Nutrition Score, and the lowest number of Low-scoring meals, while Saturdays had poorest nutritional value, with higher intakes of saturated fats and foods with higher calorie density logged more frequently.

"Tuesdays are often overlooked as just another routine day, but the data tells a different story," said Ro Huntriss, registered dietitian and chief nutrition officer at Simple Life. "While Tuesdays may be quieter in our social calendars, they appear to be when we make our healthiest choices. That's great news for Tuesdays, but to truly optimize our health and weight loss goals, it's important to also consider our eating habits on the other days of the week."

Compared to Saturdays, Tuesdays had:

• Higher shares of "Good" (38.6% vs 35.2%) and "Optimal" (16.2% vs 13.5%) meals
• Lower shares of "Low" (15.6% vs 18.8%) and "Fair" (29.6% vs 32.6%) quality meals
• More food logs labelled "Low in saturated fat" (45.2% vs 41.2%) and "Low calorie density" (38.3% vs 33.4%)
• Fewer labelled "High in saturated fat" (26.8% vs 31.1%)

The data shows a clear pattern in eating habits, with weekends often marked by indulgence and early weekdays offering a fresh start, especially by Tuesday. The findings suggest it typically takes one day, Monday, for healthier habits to take hold. These insights can inform how nutrition programs are designed and how users build lasting habits with the support of AI-powered health technology.
