The CMO of the UK, and every other medical officer wheeled out have been universally awful, they talk about covid, nothing else, they don't make any effort to discuss how you mitigate the health costs of lockdown, or of isolation.
They've not updated their guidance on exercise during a pandemic, they still encourage you to go swimming, or exercise with others, at the very same time as telling the politicians to make those things illegal.
Do nothing to say you need to eat the 10-15% fewer calories than normal because lockdown causes that much fewer demands just from the change in normal life.
And as the OP says, say nothing on ways of mitigating mental health - other than "maybe have a video call with someone".
They're killing people through this - and making people much more at risk from covid, all that isolation, all that lockdown, all those reduced fitness increases the risk of not surviving covid. If you're less fit now than you were in march, you're much more likely to die from covid, let alone all the other causes.
