How understanding glucose levels can help prevent post-meal fatigue

Lingo, a biosensor, app, and coaching programme from global healthcare leader Abbott, aims to empower people to monitor their glucose levels and form healthier habits—helping to maintain stable energy levels throughout the day.

Post-meal fatigue, known as postprandial somnolence, is often linked to blood glucose fluctuations. Dr. Amy McKenzie, Director of Clinical Research at Lingo, explains, “When you eat, especially carbohydrates, your body breaks them down into glucose. This glucose enters your bloodstream, creating a temporary energy spike. But if that spike is too rapid, your body releases insulin to manage it, which can lead to feelings of fatigue.”

The type of food you consume plays a crucial role. Diets high in processed carbohydrates and sugars cause sudden glucose spikes, making you feel tired shortly after eating. In contrast, balanced meals rich in healthy fats, fibre, and protein promote more stable glucose levels, keeping your energy steady.

Lingo benefits from over two decades of Abbott’s research in continuous glucose monitoring. It provides real-time insights into how foods affect your glucose, enabling you to tailor your eating habits and keep energy levels consistent.

Dr. McKenzie shares some practical tips: “First, choose the right foods—include vegetables, whole grains, protein, and healthy fats to maintain stable glucose levels. Second, avoid heavy meals and instead opt for smaller, balanced meals throughout the day.”

She adds that staying hydrated is essential. “Drinking six to eight glasses of water daily helps prevent fatigue caused by high glucose levels.” Moving your body after meals can also boost energy. “A gentle walk post-meal enhances glucose metabolism, reducing tiredness,” Dr. McKenzie advises.

Lastly, she emphasises the importance of meal timing. “Avoid eating too close to bedtime, as it can affect your sleep and energy the next day. Finish your last meal a few hours before going to bed.”

By understanding how your body reacts to different foods and monitoring your glucose levels, you can make smarter dietary choices, staying energised and enhancing your overall wellbeing. “Tools like Lingo help you say goodbye to those pesky ‘food comas’,” Dr. McKenzie concludes.

Over a decade ago, Abbott introduced the FreeStyle Libre, now used by over 6 million people worldwide. Built on this proven technology, Lingo is designed to bring the same benefits to a broader audience.
