Eating at least 5-6 times a day will keep your metabolism higher... 3 major meals (breakfast, lunch, and dinner) with healthy snacks in between... maybe a protein shake for lunch with some almonds or an apple. Also, always drink cold water verse room temp water. Your body burns up more calories warming the water to your body temp compared to something already warm. Working out every day may actually cause negative results... I do a 4 on 1 off that way I give my body time to recover and only running on the first and 3rd day of a workout routine while doing weight training each day--switching from legs, to arms and back, to abs etc. If you want effective, long lasting results, you've got to incorporate weights into your workouts Switch it up, shock your body... you'll definitely see a difference!
