Compact? If you train, lose weight, then no, no disadvantage. Riding the hills is all training.
You can look into the smallest ring avavilable for the compact front though. I have no idea what it would be, never been interested in a compact.
If you don't train and prepare well/long enough, then yes, you are at a disadvantage. That is when you have doubts, worry and need to depend on your gears to carry you up the hill.
All I can say is don't worry about the gearing. Get out there and ride your butt off. After 50 lbs and a huge gain in fitness, you'll figure it out then.
Save some money.
