Change the types of food you are eating? Sometimes playing with your macros a bit helps. Some people feel more satiated with more protein, other like more fat or carbs. Open your diary for more specific advice.

Yes, I exeperienced this for 3 or 4 weeks when I began strength training but then it abated. I already eat protein with every meal and minimal carbs. I have also recently increased my fibre. In the am I have a smoothie with fat-free, lactose-free greek yogurt, frozen berries and 2 tbsp ground flax seed. In the afternoon, I have a Leanfit vegan protein shake (I am not vegan but lactose intolerant) and I add extra psylium fibre. The extra fibre seems to also help and then, of course lots and lots of water :-) If I crave a treat, I make warm chocolate "pudding" with cocoa, glucomannan, almond milk and stevia - very high fibre and low carb - topped with the fat-free, lactose-free greek yogurt to add some protein. All of this sends my fibre intake through the roof but also makes me feel full :-)
