Here's an idea.
Eat like this:
Meals about every 3 hours if you can manage it. You will soon learn if this is too much or too little depending on the results you get.
Eat a balance of protein, carbohydrate, and fat with each meal. Again, as you learn your body and how it responds this is something you will adjust. Some do better with more protein than others, some need very low fat, others need lots of carbs with low fat. Others still thrive on higher fat with less carbs. A balance is a good starting place though. Something like 45% carbs, 35% protein, 20% fat with each meal.
Good food choices are, lean beef, chicken, fish, lean pork, potatoes, beans, corn, rice, whole wheat bread, whole wheat pasta, milk, juices, and fruits. Green veggies are a must - all kinds, big salads, broccoli, spinach, kale, cauliflower, asparagus, green beans, cabbage...the list goes on and on.
One cheat meal per week is a good way to make up for any missing nutrients, have a couple slices of pizza, have a burrito or enchalada...whatever you like without
paying attention to the nutrition profile.
Drinks are umm, well...water.
As you learn, if you feel that you want less fat around your workouts - it's pretty easy to choose foods so that you can have Protein/carb meals around your workout and with breakfast, then have protein/fat meals at other times of the day.
Now for the workout. Since you are kind of a beginner start with something to get acclimated to
resistance training.
Lift 3 days a week. Split the body up over those three days like this:
Legs/abs
Chest/shoulders/tris
Back
Or you can do 3 full body workouts with the simple basic exercises:
Squat, Row, Deadlift, Overhead Press, Chins.
Split - do 2 sets of 8-12, when you can get 12 reps easily, increase the weight.
Full body - start with one set of 8-12, when you can get 12 reps easily, increase the weight
If you've got a bit of fat to burn take two days a week and do cardio - start simple with walking, running, cycling, treadmill...whatever - go at a high intensity level for 15 minutes, medium intensity for 30 minutes, or low intensity (like walking) for an hour...they all work.
Later, you can learn about things like HIIT - again, once you are acclimated to working out.
If you don't have fat to burn and want to do cardio anyway - just eat a bit extra to support it, like with your weight workouts.
Once you get acclimated in a couple of months of working hard and evaluate your progress and goals here are some more specific plans to consider.
Pure strength (also gives some size)

Excellent size plus strength - big increases in strength but more bodybuilding oriented than the 5x5. Be careful here - it's great for anyone - even a beginner. But your strength gains may outstrip your body's ability to support them leading to injury - it is VERY intense.

Pure size program, can't tell you much now, I'm just partway through my first cycle of it. So far, so good, nice size gains or so I've been told but haven't seen for myself, there has been some strength and endurance increase too.

Good luck on reaching your goals, then making new ones, and going on and on and on...
