Gaining

Here is what worked for me: gained a sum of 100lbs which was 20 over my goal, lost that 20 and my belly got soft & squishy.

All this is dead on. But as someone mentioned dairy.....I would say start on Cooking with heavy cream and olive oil....you will see yourself getting soft pudge and very jiggly fat around your lower abdomen, thighs, butt, love handles and back much more than you could ever have gained in those areas before and it will start off soft and get even softer.
