The Claim
In obese adults, a 10-day protein-sparing modified fast delivered via nasogastric tube is associated with significant improvements in functional residual capacity and expiratory reserve volume.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In obese adults, a 10-day protein-sparing modified fast delivered through a tube in the nose and stomach is linked to measurable improvements in lung volume and breathing capacity, even without major weight loss.
See the scientific wording
In obese adults, a 10-day protein-sparing modified fast delivered via nasogastric tube is associated with significant improvements in functional residual capacity and expiratory reserve volume, suggesting rapid enhancement of lung mechanics independent of substantial weight loss.
When the body runs on fat-derived ketones instead of sugar, it burns abdominal fat quickly, which lifts the diaphragm and lets the lungs expand more fully during breathing. At the same time, enough protein is provided to keep the breathing muscles from breaking down, so they stay strong and work better. Together, this lets the lungs hold more air after exhaling.
What the research says
1 studyObese people who got a special low-carb liquid diet through a tube in their nose for 10 days started breathing better — their lungs could hold more air after exhaling — even though they hadn’t lost much weight yet. This suggests the diet itself, not just weight loss, helped their lungs work better.
