As long as you try to eat reasonably healthily you should be okay.

I can't eat a lot of meat so I get my protein from yogurt, eggs, and cheese, all in moderation. I do have meat occasionally, and fish most weeks, but the mobile fishmonger can't come while the country' on lockdown so there goes another source of food I can eat. I can't abide frozen fish, it's horrible, and the fresh fish in the town's fishmongers isn't very fresh, there are usually flies crawling on it which put me off.
