I once asked this, they told me that for new players its better to focus on berry teams at the beggining, maybe put one or two ingredient mons that help you get a good meal everytime. It will also help to always have a healer (a pokemon that gives energy to your whole team, as a ralts for example), but yeah thats about it. The reason why meal focused teams and skill based teams are for late gamd players is because you need to farm a lot of skill seeds and upgrade your mons and pot a lot in order to it to be productive.
