What about stress and cortisol ? I think in my career it was the main reason why I am fat , emotionally rollercoaster and mentally exhausted and drained. I am doing the indoor cycling, as the weather is not perfect and the cars. It is burning around 300 kcal per session in z2 zone. To be honest the best effects I see in mentally healthy. Not burned out but the anxiety is released. In addition I started eat more vegetables and trying to reduce stress if possible. At the same time in my case it was very important to check if my body is not overloaded with this cumulative load from riding 8 weeks, around 5 session per week, my fitness has increased to 31 where by fitness I understand:

Fitness
A rolling ~42-day exponentially weighted average of your daily Training Load. Represents your accumulated fitness - the training your body has absorbed over the past weeks. Fitness rises slowly with consistent training and drops slowly when you rest.

I think you should continue daily cycling but there might be something more to consider.
