Hi there Reach.... welcome to the Healthy Living Subcommunity. Not sure who your question is directed or regarding. Is this a friend or family member? Also if its a friend, are they wanting the help, or wanting "you" to specifically help them? I'm just trying to understand the dynamics of your question.
However, if this is regarding a "Friend"... perhaps doing things like being there for them ,supporting them through their healthy living journey, offering to do meal planning or meal prep together each week, partner up with them and help them along.........
If its for a "Family Member", are they "wanting" the support? Because that is a big thing if they are ready and willing to receieve the support offered. If they are trying to start out eating better, but don't know where to start, perhaps helping them by choosing better food options. It doesn't have to be "BIG" changes, but just "small / simple" changes..... Too much too soon can be over-whelming.
Perhaps start by "swapping" out 'White" pastas for "whole grain" pasta, .....If vegetables are a problem, perhaps trying adding them more into things like Eggs (such as tomatoes, spinach, onions,peppers....) Or...add them into a protein/health shake (you can add either spinach or fruits like bananas, strawberries etc... that you like to shakes).....For snacks, perhaps swapping out "salty" flavors like Chips with A small serving of Nuts/ peanuts. Just making "simple/ small" changes over time can add up to Bigger changes later 
Good Luck!
P.S. (Also if you search here in this "Food choices" Thread that you have posted in.. there are many other threads in here as well that you might come across that can help you as well)
