Bride to be wanting to shed 10 pounds before October 2026.

Do you mean October 2016? Because 10lbs before October 2026 should be a cinch.

10lbs in, what, 7 weeks? Set MFP's target to 1.5lbs a week, eat what it gives you, weigh & log your food accurately, track your weight and if you get stuck, you can find good advice on the forums.
