If your training at noon you most definately want to eat breakfast and possibly another meal in between. Skipping meals most likely wont make you leaner. If you want a fat burning effect in the morning remove carbs from your first meal. Just protein and fats veggies wouldnt hurt to throw in. ( example 10 egg whites 1tbspn coconut oil 1cup spinach) this can prime your body to be more efficient at burning fat. Try to have breakfast early 6-7am that way 10am rolls around you can have another meal potatoes/chicken essantial fatty acids (omegas) i choose potatoes because they faster to digest. When weight training your focus is always performance doesnt matter if your trying to lean out or not. i hope that was helpful! If you ever have a question dont hesitate to ask! I love talking about this stuff!
