What's on the Preworkout Menu?
New research conducted by British researchers further explored the relationship between fasting or eating before a workout on adipose (fat) tissue gene expression.
Have you often wondered what the best thing to eat before a workout was, or if you should even eat at all? Well, according to a new study published by the American Journal of Physiology, if your goal is to lose weight, fasting before a workout may be the best way to go. Researchers at the University of Bath in the United Kingdom conducted an experiment using a group of overweight males. The males were divided into two groups, with one group fasting before the workout and the second group consuming a high calorie/carbohydrate rich breakfast before the workout. Both groups walked at 60 minutes and 60 VO2 Max, and blood samples were taken after workout completion.

Scientists found that the gene expression in the adipose tissue differed greatly between the fasting group and the high-calorie group. The PDK4 (plays a role in the regulation of glucose and fatty-acid metabolism) and HSL (indicates stored fat mobilization) genes increased in the group that fasted before the workout, while their presence was minute for the group that ate a high-calorie breakfast before working out. These results are due to the body utilizing the high-calorie meal first for energy, before utilizing stored fat. So if your goal is to lose weight through working out, eating a high calorie/high carb meal might be something to skip out on.
