While fruit is a nutritious food with many needed antioxidants, it is still a source of sugar and can limit weight loss. Fruit contains both fructose and glucose in varying ratios depending on the fruit. Glucose is the primary sugar in starches like grains and potatoes and is the main source for glycogen for our muscles. When muscle glycogen…
There was a recent N.Y. Times article about several former “Biggest Loser” contestants who have gained most or all of their weight back. After some tests, it was found that many of them had a slower metabolic rate than would be expected from a person of their current size. This has many wondering if the extreme approach taken by the…
We’ve all seen food with words like “all natural” or “low fat” across the label. Or maybe a picture of a green leaf or tree or some natural looking character like a bee or a smiling sun trying to tell us that this food is good for us.
Just because your goal is to lose weight, don’t think you avoid lifting weights. One of the greatest benefits of resistance training is insulin sensitivity. Insulin sensitivity means that your muscles are receptive to insulin bringing fuel to be stored in the muscle- NO, this does not make you bulky. It actually provides energy for when you move those muscles.
The opposite of insulin sensitivity is insulin resistance which means that your muscles don’t respond to insulin so the fuel is diverted to your FAT CELLS for storage. Increased insulin resistance leads to, not only fat gain, but also diabetes.
You may not realize this but you’re out numbered even when you’re by yourself. You have 10 times more bacteria living in and on your body than you have human cells. Most of these bacteria reside in your gut, living on what you eat, so as you would imagine, what you eat determines the type of bacteria,or probiotics, are living in your gut.
The theory of “Calories In, Calories Out” really doesn’t work, primarily because we are not machines with a single fuel source and only one way to store and burn fuel. Our bodies are hormonal and those hormones have a tremendous effect on how we burn and store fuel, both glycogen and fat.
How many times have we heard that a calorie is a calorie? This is beyond an over simplification. It just isn’t true. Our bodies store and burn primarily two different types of fuel- fat and glycogen. We have two different metabolic systems- aerobic, being fat burning and anaerobic which burns glycogen.
Have you ever felt sluggish a couple hours after a starchy meal? Of course you have. And your first instinct, since taking a nap may not be practical at the moment, is to eat again to try to regain some energy. Generally the choice, or craving, will be for another starchy food to get your blood sugar back up.
We hear a lot about things we can do to boost our metabolism but how much of an impact do those actions really make? The majority of our metabolic rate comes from organ function and supporting our tissues. About 10% comes from the digestion of food (TEF) called the Thermic Effect of Food and 10-20% from our activity, depending on how active we are.
