Some tips that would help a picky eater at home

Throw away all junk from home. You need to stop eating them first. Ask me. I have a handful of chocolates and biscuits at home that I eat rarely when they are asleep or aren't around. Start feeding them home food right from when they start solids. Avoid giving them outside food. They will slowly get used to what you introduce to them. Give them a variety of food, fruits & vegetables. Let them choose and pick only from the healthy options. Avoid showing them unhealthy food at all. If they discover them later outside the home, they know that it's not meant for them. Plan meals each day and let the family sit together for each meal. This way, they wouldn't skip their meals and learn the right times to eat.

Apart from meal times, give them fruits, wheat, bread, juices, or homemade healthy snacks, but avoid outside snacks completely. Give them food only if they ask for it. Let them understand what hunger is, and that only good food would satisfy their hunger, not any snack. I don't completely avoid snacks. I give them very little when they spot others munching on them while travelling or with other members of the family. Also, I explain to them the harm that these snacks cause. Try to make biscuits, chocolates, icecreams & cakes at home using healthy ingredients. Google is always there to help with recipes. Don't let your laziness or your busy schedule take a toll on your health.
