Gut health affects fat storage, muscle gain, and metabolism. Learn how DEXA Scan reveals the hidden impact of your gut on body composition.

When people think about improving their body composition, they usually focus on diet, exercise, and sleep. But one of the most overlooked factors influencing fat storage, muscle gain, and metabolism is gut health.
At Kalos, we use DEXA Scan technology to give clients a clear picture of how internal factors like digestion and inflammation affect their body composition. A healthy gut doesn’t just aid digestion — it shapes how efficiently your body absorbs nutrients, builds lean mass, and burns fat.
1. Nutrient Absorption
Your gut is responsible for breaking down and absorbing nutrients like amino acids, fatty acids, and vitamins. When your microbiome is imbalanced, your body absorbs fewer nutrients from food, which can slow muscle growth and recovery.
2. Inflammation and Fat Storage
An unhealthy gut can increase systemic inflammation, elevating cortisol and insulin resistance — two hormones that promote visceral fat accumulation around the organs.
3. Metabolism and Energy Regulation
Your gut bacteria influence how efficiently your body converts food into energy. A disrupted microbiome can make you store more calories as fat, even when eating the same amount.
4. Mood and Cravings
Up to 90% of serotonin is produced in the gut. Poor gut health can lead to mood fluctuations and sugar cravings that sabotage consistency with diet and training.
While a DEXA scan doesn’t measure gut bacteria directly, it reveals their downstream impact on body composition. Clients struggling with gut imbalances often show:
By tracking these changes over time, a DEXA scan helps connect the dots between internal health and physical outcomes.
1. Eat a Diverse Diet
Aim for a variety of plant-based foods, lean proteins, and fermented products to feed beneficial bacteria.
2. Prioritize Fiber
Fiber fuels gut bacteria that help regulate inflammation and digestion. Aim for 25–35 grams per day.
3. Manage Stress and Sleep
High stress and poor sleep disrupt gut-brain communication, leading to hormonal imbalances and cravings.
4. Avoid Excess Processed Foods
Artificial sweeteners, refined carbs, and alcohol can disrupt gut flora and increase inflammation.
5. Track Progress with DEXA
A DEXA scan helps verify that improvements in gut health are reflected in better fat-to-muscle ratios and lower visceral fat.
A healthy gut means better nutrient absorption, stronger metabolism, and more efficient fat loss. By combining targeted gut health improvements with DEXA Scan tracking, you can understand how internal balance leads to external transformation.
