^^ Yes so try to incorporate these food groups into your everyday diet:
-lean meats and fish
-a variety of veggies (dark leafy greens, carrots, cabbage, beets etc) and fruits
-lower fat dairy products
-whole wheat breads, cereals, brown rice
As well, try to eat smaller meals in a day, 5-6 vs 3 large meals because it helps boost your energy, decrease appetite and increases your metabolism.
Your diet and along with your exercise routine helps immensely with losing weight and fat!
Instead of using treadmill, I recommend Beach Body Insanity workouts which range between 30min to 1hr because it forces you to perform a range of movements to work on upper and lower body. The pace is very fast the first couple of weeks, but then your body gets used to the routine they supply you.
Good luck Akira!
