what day is my big fat fabulous life on

June 28, 2026

My Big Fat Fabulous Life aired on Tuesdays at 9:00 PM ET on TLC based on the latest schedule I found for the series’ 2025 season.

What that means

The show’s Season 13 premiere was listed for Tuesday, July 1, 2025 at 9 PM ET on TLC.

Another episode listing shows the series continuing on Tuesdays in that same time slot.

Note

TV schedules can shift by season or by region, so the safest answer is that it was scheduled for Tuesday nights on TLC in the most recent listings I found.

If you want, I can also check the current season episode schedule and tell you the next air date.
