Both of these excuses are based on a lack of preparation. By planning ahead you can deal with sudden lack of motivation or unexpected meetings that make you miss your regular meal times.
So how do you prepare and plan ahead? I like to always carry a water bottle with me, so that when I get thirsty I won't be tempted to buy a soda from the nearest store or cafeteria. Furthermore, it's a good idea to carry with you some fruit or a ready-made sandwich when you know your day is gonna be hectic.
There are many meals that you can prepare in advance for those times when you really don't want to cook anything. Another tip is to make too much food, so that you then can eat leftovers the next day or two. Lasagne or pasta bolognese are excellent options.
But most importantly, you have to find a way that works for you. Maybe it's planning your daily meals a week ahead, or maybe you prefer making your lunch at home in the morning and bring it with you.

Hummus is an absolute life saver for me. High in protein, versatile and delicious. Easy to pair with veggies or crackers or both!
For lunch, a sandwich made with whole wheat bread, salad, tomatoes, egg or canned tuna, or you can try also with light cheese spread, smoked salmon and avocado
