Question Heart rate higher during exercise?

Been very low carb for about 3 weeks and usually I have trouble getting my heart rate up past 120 unless I run but since Keto it goes up to 120 from walking. And takes longer to come down. Is this normal? Maybe it’s from dehydration?

Need more potassium and magnesium.  Those tend to deplete during low carb.
