Exercising after eating can have immediate benefits on lowering blood sugar peaks. However, exercising before breakfast can lead to longer-term improvements including improved insulin response and potentially enhanced fat burning. This may have positive effects on overall health outcomes, although not necessarily weight loss. A study showed that exercising without eating beforehand did not negatively impact performance, even for regular individuals. Skipping breakfast or delaying it until after exercise generally only affects the training sessions of elite athletes. Most people have enough fuel from the previous day for a typical exercise session of up to an hour or an hour and a half. It is possible to mix and match exercising before or after breakfast, depending on personal preferences. The practice of intermittent fasting, though not followed regularly by the speaker, has been effective in controlling blood sugar levels. Overall, the speaker endorses the benefits of exercising before breakfast based on personal experience and the understanding that it positively influences blood sugar control.
