You should learn how to cook. YouTube videos galore. Food recipes are all over the web. This will teach you what foods you enjoy making and eating. This will also slow your cravings and enjoy what you eat.

Once you have figured out what like making and eating then you start to invest in some basic cooking utensils to start with. A decent set of knives and a good chopping board. A spice rack. A Digital Slowcooker, Instapot and/or an Digital Airfryer if you want to save time and money in the long run.

You can then experiment with various recipes as you get more advanced. Start of slow by learning basic dishes to cook and then advance to more complex dishes. Set a goal of cooking at least 4 meals a week to begin with. You will fail all lot at first, burn a bunch of things. You will get better as get more patient and more skilled. Stop ordering takeout and delivery. You will learn that you can cook some dishes faster than it takes delivery to come to your house.

And most importantly drink water instead of soda and sugary drinks. Water tempers your appetite and craving for snacks.
