Eat Multiple Small Meals
What works for me is eating multiple times a day, 5-6 small meals a day. Nothing heavy of course. A small meal consists of some kind of fruit, yogurt or oatmeal for breakfast, fruit or trail mix for snack, something light for lunch (tuna with fruit or vegetable), another fruit or something light for a snack, and for dinner (salad, soup, wrap, etc.) You could also do a light snack before bed but make sure you eat it at least 1-2 hours before you go to sleep.
Drink a lot of Water
The recommended formula for water consumption is for an individual to drink half of their weight in ounces of water. Example: 200 pounds = 100 ounces of water. To help with portion control, if you drink a cup of water before your meals then you will get full quicker and not over indulge with food.
These are definitely things that I live by. I feel as if I am always hungry, but I eat 5-6 times a day and they are small meals. People around me look at me and think, “dang she eats a lot and is always hungry”. When I get hungry, I snack on something healthy and that helps boost my metabolism. Exercise does help too, but as far as metabolism is concerned, it is mainly your diet.
What are things you struggle with in your diet that can be impacting your metabolism?
