The Claim

In overweight and obese young adults, early time-restricted eating is associated with lower concentrations of thyroid-stimulating hormone (TSH) and triiodothyronine (TT3) compared to late time-restricted eating and a control group.

In plain English

In overweight and obese young adults, eating only during an earlier part of the day is linked to lower levels of thyroid-stimulating hormone and triiodothyronine than eating later in the day or eating without time restrictions.

See the scientific wording

In overweight and obese young adults, early time-restricted eating was associated with a reduction in thyroid-stimulating hormone (TSH) and triiodothyronine (TT3) compared to late TRE and control, potentially reflecting adaptive metabolic suppression during prolonged fasting, though the clinical significance remains unclear.

Why this might work

When food is only eaten early in the day, the body fasts for longer before morning, signaling a sustained energy shortage. This causes the brain to reduce signals that tell the thyroid gland to produce metabolic hormones, lowering the body's energy use to conserve fuel.

  1. Study: Randomized controlled trial for time-restricted eating in overweight and obese young adults

    Eating all your meals early in the day led to a small drop in two hormones that control metabolism, probably because fasting longer at night slows down your body’s energy use. This didn’t happen when people ate later.
