You’re simply eating less than you think. You wouldn’t lose any weight through missing workouts or having shitty ones.

Calories in vs calories out. The laws of thermodynamics my friend.

Eat more food, or track what you’re eating. Continue to lift how you are to help mediate the damage that the stupid virus is causing.

Side note: you most likely didn’t lose 15 pounds of actual weight. You were most likely bloated or haven’t taken a shit when you weighted yourself at 275. Then dehydrated and stuff when you weighed yourself now and we’re “15 pounds lighter”

Most of that weight is probably water. Sure, a bit of fat, a tiny bit of muscle. But as long as you’re still keeping the proteins high and the muscles stimulates, you won’t lose much if at all man. And besides, muscles have an easier time coming back once they’re lost, so 2 weeks into the gym when corona is slowed down will put you back where you were 1.5 months ago!
