Research has repeatedly demonstrated the benefits that regular exercise has on our health. It plays a large role in reducing the incidence and risk of lifestyle diseases such as cardiovascular disease, type 2 diabetes and other age-related ailments. We often see individuals who participate in physical activity, either structured or unstructured, in more social environments - something that is of benefit to one's social wellbeing and psychological health.
For some, a new year means a new you. While many will have adopted new exercise strategies as part of their resolutions to lose some holiday weight, exercise scientists and dietitians are often questioned about the influence exercise uptake has on your appetite - in particular, does exercise increase your appetite and therefore reduce the effectiveness of you achieving your health or weight goals?
The short answer is, exercise and appetite are not the issue, but rather food choice. It's easy to think you have "earnt" a sweet treat, after a hard work out. But if you are looking to lose weight, this is a false economy.
Of the research that has investigated appetite and exercise, some did observe an increase in food intake following exercise, however, an overall negative energy balance was still achieved. Because the energy expenditure during exercise was greater than the increase in food intake in the period following exercise. So, this would still be beneficial for your weight loss.
If people are struggling to lose weight, it is more likely a result of their food choices. It's easy to reach for the high-kilojoule, high-sugar foods after hitting the gym, but if you are looking to drop the kilos, these types of foods should be avoided - soft drinks, chocolate, takeaway foods and alcohol - in the immediate post-exercise period and during your everyday diet. You may also need to be aware of non-hungry eating, like when you're bored or as a form of procrastination.
