The Claim
In obese adults, a 10-day protein-sparing modified fast delivered via nasogastric tube is associated with no significant loss of handgrip strength.
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.
Obese adults who follow a 10-day protein-sparing modified fast through a nasogastric tube maintain their handgrip strength despite losing weight and fat-free mass.
See the scientific wording
In obese adults, a 10-day protein-sparing modified fast delivered via nasogastric tube is associated with no significant loss of handgrip strength, suggesting preservation of skeletal muscle function despite significant weight loss and fat-free mass fluctuations.
When carbohydrates are removed, the body switches to burning fat for fuel and produces ketones, which the brain and muscles use instead of glucose. This reduces the need to break down muscle for energy. At the same time, a steady supply of protein from the feeding tube provides the building blocks needed to maintain muscle tissue. As a result, muscle strength stays strong even though the body loses weight quickly.
What the research says
1 studyEven though people lost a lot of weight quickly using a special tube-fed diet, their hand strength didn't get weaker—meaning their muscles stayed strong.
