The observation shared here is particularly accurate and aligns with exercise science. A meta-analysis by Schoenfeld et al. (2014), which grouped several randomized controlled trials (RCTs), confirms that there is no difference in long-term fat mass loss between fasted and fed training. In the short term, another meta-analysis by Vieira et al. (2016) validates the fact that fasted exercise indeed increases the use of fat as fuel during exertion. However, as the expert points out, the body compensates for this usage by burning fewer fats and more carbohydrates for the rest of the day. This is an excellent demystification showing that for weight management, consistency and total daily caloric intake take precedence over meal timing.

What’s uncertain
The body-composition evidence base is small. Burning more fat during a fasted session doesn't mean more fat lost over time. The 'women should never train fasted' claim lacks strong supporting evidence, though some people simply feel better training fed.
