Change your mind about carbohydrates!

I hear in different conversations that carbs/carbohydrates are bad for us and and pack on the pounds.

Guess what..... Not true!

While I don't know absolutely everything (no one does) what I do know is carbohydrates aren't bad for us. There are diets out there that seem to have some variation on eating fewer carbs or low/no carbs.

First I would like to say that not all carbohydrates are the same. Our body reacts differently to simple carbs vs. complex carbs.

For example if I were to eat a cookie that was 120 calories vs. 120 calories worth of brown rice or 120 calories of apple slices my body would react differently to the cookie vs. the brown rice or apple.

Complex Carbohydrates:

Apple = Aprox 4.5 grams fiber, natural sugars (fructose), Potassium,  Iron, Magnesium, Manganese, Phosphorus, Sodium, Zinc, B1, B6, B1, E, C, A

Brown Rice = 1.8 grams fiber, 2.32 grams protein, Calcium, iron, Magnesium, Phosphorus, Potassium, Sodium, Zinc, Vitamin C, Thiamin, Riboflavin, Niacin, Folate, B6,


Simple Carbohydrates:

Cookies typically contain = very little if any fiber,  white flour, sugar and butter or hydrogenated oils/fats


If I were to eat brown rice or an apple I would be satiated as these foods have fiber in them and or protein. Fiber and protein helps me feel full and slows down the emptying of my stomach. This leads to me feeling fuller longer and helps with stabilizing blood sugar vs. giving my body a sugar high and then a crash. If I were to eat a cookie that was 120 calories I would still be hungry which would lead to a few more cookies and a lot more fat, sugar and calories to only be hungry again a short time later after the sugar crash.

An excess amount of calories = weight gain.

I've found through my many years of experience with weight loss and weight gain that whole foods work!  Whole foods keep me satiated and fuller longer than simple carbs like: white bread, muffins, white rice, cookies.... (all the things I love!)


What are carbohydrates good for?

1. Carbohydrates are an energy source for our body. Carbohydrates are stored in our muscles as glycogen and in our cells as glucose. Any excess glucose in our body is stored as fat (importance of watching our calorie intake). Glycogen/glucose is what powers our muscles during activity both anaerobically (jumping) and aerobically (long slow distance).

2. Protein sparer. Carbohydrates preserve our muscle tissue protiens. The job of protein is to help maintain muscle tissue, repair and grow. If there aren't enough carbohydrates muscle tissue and fat is used for fuel through glyconeogenesis (the breakdown of protein and fat to be converted to glucose).

Glyconeogenesis occurs under these conditions:
a. Dietary Restriction - consuming little or no carbohydrates - not enough calories.
b. Prolonged Exercise - glycogen/glucose stores are depleted during the activity without any additional fuel.
c. Intense training - repeatedly.

3. Metablolic Primer. Carbohydrates serve as a primer for fat to be used as energy. The byproducts of carbohydrate breaking down is what serves as a primer to burn fat for energy. The body can not have a sustained high level of activity (aerobic) from fat only (less intense of a workout = fewer calories burned). The body needs carbohydrates.

4. Central Nervous System (brain and spinal cord). Our brain relies on carbohydrates exclusively to function. The brain gets the carbohydrates in the form of blood glucose. The brain doesn't have the capability of creating a storage of glucose to be used later (like our muscles do). During intense exercise our muscles use what glycogen and blood glucose is available. Blood glucose eventually decreases below normal and the body can have mild symptoms of hypoglycemia (weakness, hunger, dizziness). Exercise performance decreases and fatigue sets in.

Summary
Are carbohydrates bad? No!

There are valuable micro and macro nutrients that we could be missing if we avoid foods that contain carbohydrates.

Eat whole foods and you will be eating complex carbohydrates = fiber, protein, vitamins, minerals, glycogen and glucose for your brain and muscles. Stay away from as much processed food as you can.

Weight Loss = our bodies using up more calories than we consume.

Cheers!

The #MeToo Campaign

Fingers crossed that this trend continues. For the past 10 days, I've been feeling energetic for the first time since? It's been so long I can't remember. I'm feeling cautiously optimistic. It feels like I don't have depression anymore. What an amazing feeling that I hope never ends. Its kind of ironic as this time of year gets difficult with the shorter days. I've been using my Verilux lamp in the morning as I have for the last few years so I'm not sure if that has anything to do with why I'm feeling good? I'm feeling better now than I did a year ago. 

Depression doesn't affect me in ways someone might think when it comes to energy. I'm high functioning in that I'm not catatonic. It's just that my energy is limited (occasionally it feels like gravity is turned up or I'm trying to walk through waist-deep snow thankfully not often). A friend once explained to me what it's like to have Lyme disease (unfortunately she has chronic…

Weight Watchers vs. Jillian Michael's

It's been a little over 3 years (January 2010) since I started my weight loss journey. I reached my goal weight in May of 2011 (135 lbs). Since then it's been a yoyo and my trend had been going up over the last several months. My current weight is 150 lbs (I was 155 but lost 5lbs over the last few weeks). My goal is to lose the weight I put back on (20 lbs) plus an additional 5 lbs for a weight loss of 25 lbs in total. It's so hard keeping the weight off!!

The strategy I'm now doing this time is different. I've decided to follow Jillian Michael's weight loss program instead of continuing on with Weight Watchers. I lost the 80lbs on Weight Watchers and the program served me well. It forced me to look at portion size, calories (with old points system), fiber, carbs, fat and protein (with the new points plus system).  It changed the way I looked at food. Instead of processed foods I focused on eating a variety of whole fruits, vegetables, legumes, grains and low …

Trying the 'New' Weight Watchers Program

I've been on the new WW program starting January 11th, 2018 (to date 3/21/2018 I've lost 7 lbs).  Why? Because what do I have to lose besides pounds of course!? My sanity perhaps on what seems like a life long journey. Woops! Too late!

My ultimate goal in life when it comes to health and weight loss is to be able to eat without counting calories or points. That can be very difficult for me. Since starting this blog I have earned a degree in Exercise Science and I now have certifications: ACSM CPT, ACE GFI and I've completed coursework to be a licensed coach in my state. With all my education and personal experience (80 lb weight loss) I would have thought things would be easier by now but they're not. Science has proven that when it comes to weight loss it's calories in vs. calories out. Unfortunately calorie counting doesn't account for all the psychological, sociological and biological reasons why we eat what we eat. I need to try a new approach so I'm g…
