What to do?

[GLC1968]

Perhaps the best approach isn't either A or B, but both/and - mix it up.

This.

You definitely need the weight training to keep the muscle as you burn the fat. You won't be able to add sizeable muscle while in a calorie deficit, but you want to retain as much of it as possible. Put simply, if you don't use it, you lose it and that is horribly detrimental to your ability to maintain your loss.

Plus, variety is the spice of life, right? I find that mixing things up keeps me entertained and if I am entertained, I am way more likely to keep going.

Just keep doing what you are doing. Keep the diet in check, keep the activity up, and keep lifting weights - you'll get there. The single most important factor in weight loss is consistency (I should know...I don't have it!! ) and if you have that, you'll get there.
