Exercising before breakfast trains your fat tissues to break themselves down
If you want to lose fat by doing more exercise, then exercise as much as possible on an empty stomach. In the short term doing this burns more fat than if you exercise while you've still got a lot of nutrients in the bloodstream, but in the long term the slimming effect is even stronger. By exercising before breakfast you probably train your fat tissues to break themselves down. British researchers at the University of Bath reached this conclusion in a small human study.
Study
On one occasion the men ran on an empty stomach [Fasted]; on the other occasion they ran two hours after having eaten a breakfast of about 650 kilocalories [Fed].
Results
That was not much of a surprise. More interesting was what happened to the men's fat tissue. Jogging activated all kinds of genes that stimulate fat burning, but this happened mainly after jogging in the fasted state.
The table below is simplified. Click on it and the real thing will appear.
ATGL adipose triglyceride lipase, an enzyme that splits fat in fat cells into free fatty acids and glycerol.
Conclusion
"Given the nature and direction of these differences, we propose that feeding is likely to blunt long-term adaptations induced within adipose tissue in response to regular exercise."
So if you exercise after a meal, your fat tissue is faced with "competing challenges", explained the research team leader Dylan Thompson of the University of Bath in a press release. [sciencedaily.com April 6, 2017]
"After eating, adipose tissue is busy responding to the meal, and a bout of exercise at this time will not stimulate the same [beneficial] changes in adipose tissue. This means that exercise in a fasted state might provoke more favorable changes in adipose tissue, and this could be beneficial for health in the long term."
