Exercising Before Breakfast May Provide Substantial Health Benefits – Study
A recent study done by the University of Bath shows that exercising before eating breakfast can have a significant positive impact on overall health. The study was conducted over a period of 6 weeks with 30 men classified as overweight or obese. During the study, researchers examined a group who ate breakfast before exercising, a group that ate breakfast after exercising, and the control group who made no changes.
The results of the study showed that while eating breakfast before or after working out did not make significant differences in terms of weight loss, those who ate breakfast after working out increased their body’s ability to respond to insulin. Additionally, those who ate breakfast after workout burned more fat and saw general improvements in their overall health.
We found that the men in the study who exercised before breakfast burned double the amount of fat than the group who exercised after. Importantly, whilst this didn’t have any effect on weight loss, it did dramatically improve their overall health.”

Subjects not in the control group ate a breakfast of cornflake cereal in skimmed milk with wholemeal toast, sunflower spread, and strawberry jam. The group who ate breakfast first, ate breakfast and then allowed for a 90-minute “rest and digestion” period and then exercised by cycling on stationary bikes for 60 minutes, the group who ate breakfast after working out participated in the same exercise and then immediately ate breakfast.

Breath samples and blood samples were collected at the 25-30 minute mark, and again at the 55-60 minute mark, to determine which fuels were being used to power the cyclist. The results of the data collected show that moderate-intensity exercising before eating breakfast can help regulate insulin, regulate blood sugar, as well as burn more fat. Both those who ate breakfast before and after working out lost weight at the same rate, however, the group who ate breakfast before working out saw no changes in their body’s response to insulin.
The group who exercised before breakfast increased their ability to respond to insulin, which is all the more remarkable given that both exercise groups lost a similar amount of weight, and both gained a similar amount of fitness. The only difference was the timing of the food intake.”
