Meal skipping, whether deliberate, as in intermittent fasting (IF), or accidental amid hectic schedules has become an increasingly common dietary pattern among adults. However, as Aditi Prasad Apte, Senior
Clinical Nutritionist, Aster RV Hospital, Bangalore explains, its impact on metabolic health is more complex than it appears.
“Epidemiological and experimental studies have shown that skipping breakfast, lunch, or dinner can alter glycaemic control, appetite hormones, and overall energy balance,” says Apte. “At the same time, findings remain inconsistent, which makes it important to look at individual patterns rather than generalise.”
Skipping meals, particularly breakfast, can lead to extended fasting periods. “While this may initially lower blood glucose levels, it often results in overeating later in the day,” notes Apte. This pattern creates rapid fluctuations in blood sugar, placing stress on insulin regulation and increasing the long-term risk of Type 2 diabetes.
Irregular meal timings can also slow metabolism. “When the body senses inconsistency, it adapts by conserving energy and storing more fat,” she explains. “Over time, this can contribute to weight gain and metabolic imbalance.”
Late-night eating further compounds the issue. “The body’s ability to metabolise glucose and fats naturally declines in the evening,” says Apte. “As a result, calories consumed late at night are more likely to be stored rather than used for energy.” This not only contributes to weight gain but is also linked to obesity and metabolic syndrome.
Additionally, late meals can disrupt sleep quality. “There’s a strong connection between late-night eating and poor sleep,” she adds. “Disrupted sleep can further impact metabolic regulation and appetite hormones like ghrelin and leptin, creating a vicious cycle.”
There is also growing evidence that inconsistent eating schedules affect gut health. “Irregular patterns can lead to digestive discomfort, bloating, and even changes in the gut microbiome,” says Apte. Over time, these factors may increase the risk of cardiovascular issues, insulin resistance, and chronic inflammation.
So, what’s the solution? According to Apte, consistency is key. “Maintaining regular meal timings aligned with daylight hours can significantly improve metabolic outcomes,” she says. “A balanced breakfast, evenly spaced meals, and avoiding heavy dinners late at night are simple but effective strategies.”
Ultimately, when and how we eat is just as important as what we eat. “Regularising meal patterns is a foundational step towards preventing long-term metabolic disorders and supporting overall well-being,” concludes Apte.
