Learn what causes energy crashes during the day and how body composition tracking with a Dexa Scan can help improve energy levels.

Many people experience sudden drops in energy during the day, often referred to as “energy crashes.” These can affect productivity, focus, and overall wellbeing, even in individuals who are otherwise healthy and active.
Energy crashes are rarely random. They are usually the result of underlying issues related to nutrition, sleep, activity levels, and metabolic health.
This article explains what causes energy crashes during the day, and how improving fitness habits and tracking body composition with a Dexa Scan can help stabilize energy levels over time.
One of the most common causes of energy crashes is unstable blood sugar.
Large spikes and drops in blood sugar can occur when meals are high in:
After a spike in blood sugar, a rapid drop can lead to:
Balanced meals that include protein, fiber, and healthy fats help maintain stable energy levels.
Sleep plays a major role in energy regulation.
Insufficient or poor-quality sleep can lead to:
Sleep deprivation also disrupts hormones that regulate appetite and energy balance.
Even mild dehydration can impact energy levels.
Dehydration can cause:
Maintaining adequate hydration supports circulation, nutrient delivery, and overall energy production.
A sedentary lifestyle can contribute to low energy levels.
While it may seem counterintuitive, regular physical activity helps:
Consistent movement throughout the day supports sustained energy.
Lean muscle mass plays a key role in metabolic health.
Lower muscle mass can lead to:
Building and maintaining muscle through strength training supports more consistent energy levels.
Higher levels of visceral fat are associated with metabolic inefficiencies.
This can contribute to:
Because visceral fat is not always visible, it often goes unnoticed without proper measurement.
Energy production is closely linked to body composition.
Higher lean muscle mass supports:
Higher visceral fat levels may impair these processes.
A Dexa Scan provides detailed body composition analysis.
It measures:
This information helps identify whether body composition may be contributing to energy fluctuations.
The scan itself takes about six minutes, making it efficient and convenient.
To monitor improvements in energy and metabolic health:
Frequent tracking allows you to see how lifestyle changes are affecting your body.
Full body composition Dexa scans are not covered by insurance, making them a proactive investment in long-term health.
To improve energy stability:
Addressing these factors can significantly reduce energy fluctuations.
Energy crashes during the day are usually caused by a combination of:
Improving these areas supports more stable and consistent energy throughout the day.
Tracking body composition provides insight into how your body’s structure may be influencing your energy levels.
If you want to understand how your body composition may be affecting your energy levels, accurate measurement is essential. Kalos provides advanced Dexa Scan services to help you track muscle mass, fat levels, and metabolic health with precision.
