The Claim
In healthy young active men, low-intensity walking performed after a meal does not increase fat oxidation compared to walking in a fasted state, despite differences in hormonal and substrate availability.
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 healthy young active men, walking at a low intensity after eating does not result in higher fat oxidation than walking before eating, even though the body's fuel sources and hormones differ between these two states.
See the scientific wording
In healthy young active men, low-intensity walking performed after a meal does not increase fat oxidation compared to walking in a fasted state, despite differences in hormonal and substrate availability.
After eating, insulin rises and blocks the body from burning fat for energy, even though more fat is available in the blood. During walking, the body still uses that fat, but insulin keeps the fat-burning process turned off. In a fasted state, fat is released into the blood, but without insulin to block it, the body still doesn't burn more fat because the exercise intensity is too low to trigger greater fat use.
What the research says
1 studyStudy: Cardiorespiratory, enzymatic and hormonal responses during and after walking while fasting
This study found that walking after eating doesn’t make your body burn more fat than walking before eating, even though your blood sugar and stress hormones change. So, eating before a walk doesn’t help you burn more fat.
