The numbers
10,000 steps burns roughly 300–500 kcal for most adults. Paired with a 250 kcal food deficit, that's 1.5 lbs of fat per week.
Two 15-minute walks after meals lower post-meal blood glucose meaningfully.
Add strength once a week
One or two strength sessions a week keep muscle during the cut — walking alone can lose some lean mass if protein is low.
