AIIMS Doctor Explains Why Dinner Time Matters More Than Diet
Dr. Saurabh Sethi, a gut specialist, explains why the time you eat dinner is more important than what you eat.
Eating late can slow down fat burning, make it harder for your body to use insulin, and mess up your sleep.
On the other hand, eating early can help your body use insulin better, reduce sugar levels at night, and improve sleep.
Even a small difference of 2.5 hours can make a big impact.
This is especially important for people with diabetes, prediabetes, or fatty liver, as they can have much higher sugar spikes if they eat late.
Dr. Sethi suggests that eating early can help manage these conditions, improve sleep, and boost gut health without needing extreme lifestyle changes.
Eating late dinners can slow fat burning, reduce insulin sensitivity, and disrupt sleep hormones.
Early dinners improve insulin sensitivity, reduce nighttime glucose levels, and enhance sleep quality.
A 2.5-hour difference in dinner time can significantly impact gut health and sugar spikes.
People with diabetes, prediabetes, and fatty liver are at higher risk and may experience 30-50% higher sugar spikes with late dinners.
Aligning dinner time with natural circadian rhythms can improve overall health and manage disorders.
