What would happen if you ate the same amount of calories but say, slacked hard-core on the veggies, or ate too much protein? Would it affect your energy, your complexion, weight, strength, or nothing? I've never thought in terms of macros really until a few months ago so I'm still trying to get it.
Sara, you just asked the million dollar question. HA....this is my favorite subject...and now that I've bored friends/family/co-workers to death with it I get to bore you as well!
My weight might, or might not stay the same. But weight management has very little to do with my food choices because some of them are very, very calorie dense (i.e. avocado, milled flax, buckwheat, bananas, legumes, nuts). Obviously, I could eat a heck of a lot more food if I just stuck to the "low calorie" side of the menu.
But, If I slacked "hard-core" on getting in my fruits/veggies, or just chose to eat a lot of protein dense foods (say meat/eggs/dairy) instead of a diet balanced with more plant food (including nuts/seeds/legumes), my energy level, mood, mental functioning and general health would suffer greatly. I 100% believe this. I first started off on hard-core Atkins...20 grams of carbs a day...to break my sugar addiction. When I started reintroducing carbs by way of veggies and then fruits, then legumes, etc., it was on a limited, progressive basis (an increase of roughly 20 grams a week) and, because I wanted to get the most "bang" for my buck, I started looking hard at the nutritional values of individual fruits/veggies in order to select which ones got reintroduced each week.
And I gotta tell you I was stunned, shocked and amazed at how important they are. It was a major, an ongoing learning process for me. I learned (and am still learning) a crapload of "stuff" I never knew. Stuff like the fact that fruit like blueberries, raspberries, and cherries help prevent the oxidation of cholesterol which is as important, if not more important than the amount of cholesterol itself. Stuff like the fact that about 70% of the immune system lies in the digestive system and the foods that provide the greatest support to a healthy digestive tract - fruits and veggies. And the foods containing the most powerful disease preventative polynutrients? Yep, all found in the plant family. And here's a good one: quercetin is a powerful antioxidant that helps neutralize free radicals...it's sold as an expensive supplement....or cheap in the produce aisle (red apples & onions).
