One key thing to do is add more fiber to your diet. This is smart for anyone in any circumstance, really. But natural fiber from veggies and grains help eliminate water weight, which a lot of people confuse with fat gain. If you weigh yourself daily, the drastic fluctuations you might notice are actually just variations in how much water your body is retaining from day to day.
Higher fiber and less sodium will help your body regulate the water it retains, and this will help give you a slimmer and less daunting body shape. It won't necessarily help you reduce body fat, but from a visual perspective you'll have a more accurate idea of what your other fitness and dietary goals should be.
One thing, though, ironically, is that when you increase your fiber intake, be sure to drink more water. Sounds counterintuitive, but your body needs sufficient water to break down and absorb the fiber -- so the fiber can reduce your water weight. The human body is just, like, the weirdest thing!
I used to have chronic bloating until I increased my fiber and water intake. I still have a chubby-wubby belly, but at least it's not being made worse by too much water weight.
