The quickest way to rectify matters is likely to dismiss excess troops.You can always train more when you have done so,or progressed more.
Although its a battle game and troops at home could help you defend your town, you dont need them if you are shielded, and you only need as many troops as you can send out on consecutive marches.
Yes there are onslaughts,but without knowing exactly what your set up is, its difficult to be specific.
Only heros gear that actually increases food production is going to help, so blindly forging and swopping is of little use.
There are other boosts,but again we do not know what assets you have, or what real money you are spending.
If you are all new players in a new kingdom,you might not have anyone to ask for advice.
Look at the heroes gear again, and study it properly, the things that you need and can afford, are liklely to be near the bottom of the tables, and amulets should be considered first.
Also redo your heros skills or next time you level up concentrate on production, especially food
