Choosing foods for fat loss is all about process
Now that we have looked at all the various indexes that are suppose to help us chose the proper foods for fat loss, it is time to get down to the real issue. How can you make intelligent decisions when it comes to planning meals? Does every food you choose have to have a Glycemic index of less than 50, a Glycemic load of less than 10 and, and a satiety index of more than 100? Good luck with that! As I said before, the various indexs are not in agreement on what foods are best and what are worst. Personally I have no desire to look up every food I choose before I eat it to see where it ranks either. There is an easier way. All we have to do is apply some common sense and everything else seems to fall into place.
Essentially what was trying to be achieved by all of these indexes was 3 things:
- control insulin secretion and stabilize blood sugar levels.
- control calories
- control hunger
These are 3 important things in my opinion if dropping bodyfat is your goal. All 3 of these factors go hand in hand as well. Keeping your blood sugar stable throughout the day will control your hunger so you eat less calories overall. If you eat fewer calories than your body burns you will be in a deficit and will lose fat. Sounds pretty simple, and it actually is. You just have to chose foods (or eliminate foods) based on one single question.
- How processed is this food?
Processing food essentially prechews, predigests, and preserves it. Processing also removes water from a food and replaces it with fat, usually a saturated or trans fat so it will keep on the shelf longer. Processing usually strips most if not all of the fiber out of the food, and adds salt and other “spices” (MSG is classified as a spice). All of these things make the food taste better. Unfortunately all of the processes cause a food have a greater impact on insulin secretion, allow us to eat more before we realize we are full, and cause use to be hungry again soon after eating.
Lets use the simple potato as an example of how processing affects a food and how that affects you. A baked russet potato has next to no processing. It has been washed (it better be anyway) poked a few times and baked. A 7.5oz potato has 168 calories, 0.2 g of fat and 4 g of fiber. If we go to the extreme end of processing, potato chips, a 7.5 oz serving has 1123 calories, 67.5 g of fat and 7.5 g of fiber. Nearly all of the additional calories in the chips are from fat. That is because the water in the potato that has zero calories has been replaced with fat that contains 9 calories per gram. This is a very extreme example, but lets compare baked french fries that you buy and prepare at home. They are just cut up potato that is frozen right? What’s the difference between that and a whole potato? Well all you have to do is flip them both over and read the ingredients. I had a hard time finding the ingredients label on the potato but I am going to go out on a limb and say it contains “potato”. The bagged frozen potato contained not less than 10 ingredients, Potatoes, Sunflower Oil, Batter (Wheat Flour, Modified Starch (Maize, Tapioca), Rice Flour, Salt, Corn Starch, Natural Colours (Turmeric Extract, Paprika Extract)) A 7.5 oz serving of these potatoes was 365 calories. More than double what an actual potato is. This of course does not include any oil you use in the cooking process and anything you add afterwards. Also of note, if you cooked and broke one of these fries open, it was obvious that the rough, starchy, consistency of a potato was not there. It was more like it had been mashed to almost a liquid and then pressed into its current shape. Your body has to do very little to break these “potatoes” down, they almost melt in your mouth. Like they had already been pre chewed. This makes it very easy for you to eat a tremendous amount of calories in no time. A high intake of easily digested food spikes your blood glucose and causes a insulin spike to deal with the sugar in the blood steam. Once the insulin has dealt with the glucose you become hungry again. The less food you eat and the longer it takes to digest the more stable your blood sugar remains and the lower the insulin response.
There are many other factors I consider when I design a fat loss diet for a client, like individual lifestyle factors, macronutrient breakdown, and portion size, but people can make tremendous progress just by eliminating processed foods as much from their diets as possible. We need to worry about the elephant in the living room crapping on the floor instead of the dust on the blinds. Try this the next time you go grocery shopping. Try to buy as many things as possible with no label. The things you do buy with labels, try the limit the ingredient list to 3 or less. You might be surprised how different you cart looks going through the checkout. In a short time you might be surprised how you look to.
