The Claim

In obese, insulin-resistant men, the distribution of daily caloric intake between morning and evening has no effect on resting energy expenditure or respiratory quotient during weight loss.

Description
1 study reviewed
In plain English

In obese men with insulin resistance, spreading calories throughout the day versus eating more in the morning or evening does not change how many calories the body burns at rest or how it uses fuel during weight loss.

See the scientific wording

In obese, insulin-resistant men, the distribution of daily caloric intake between morning and evening does not influence resting energy expenditure or respiratory quotient during weight loss.

Why this might work

When people lose weight, their bodies burn calories and use fuel the same way no matter if they eat most of their food in the morning or evening, because the total amount of food and the body’s hormones stay the same, so the liver and muscles don’t change how they process energy.

  1. Study: Meal timing effects on insulin sensitivity and intrahepatic triglycerides during weight loss

    When obese men with insulin resistance lose weight, whether they eat most of their food in the morning or evening doesn’t change how many calories they burn while resting or how their body uses fuel — and this study proves it by testing both groups and finding no difference.
