a. Energy for Digestion: When food is cooked, the raw form has changed so it can easily disintegrate and digest. This energy supplied to break it down came from fire and does not have to come from the body, making the cooked food more energy dense. To give you an example, celery if consumed raw, the body needs more energy to digest it compared to cooked celery. So raw vegetables need more caloric energy to digest but still the net is positive energy, but lower levels as some of the generated energy is needed to consume the next raw food. So based on this, if you can create juices that you can consume using raw vegetables and fruits, you can spend energy simply digesting this. There are foods that require such high energy to break them down for digestion, they even can have negative calories i.e. more energy is needed to digest than the energy they release. This does not mean they burn more calories, but simply that the calorie content is low and the body spends a lot of energy grinding them down chemically.
b. Diversity of Food Groups: Some of the foods were not palatable in the raw form but cooking allowed to take away the unwanted taste, allowing more food variety to be consumed. Using grinding or juicing as a way to break down food rather than cooking, a variety of nontasteful vegetables can be mixed into fruits creating a lower calorie mix as fruits have large amounts of sugar.
c. Concentration: To understand this, take sugar cane for example. You need to eat a foot long round sugar cane, expend quite a bit of energy to garner a spoonful of sugar. By then, you feel full so cannot eat a lot more. But if you consume the processed spoonful sugar, it is concentrated and refined so you need to expend less energy, it takes up less volume in your stomach and now you still have room to eat more. So the more concentrated and processed food you eat, it’s high in energy output density per gram and the more weight you put on. So by gravitating more towards unprocessed foods, ideally raw form, the less concentrated high energy food you are consuming.
Given that food cravings is as much an addiction and mental discipline problem, the above may be less difficult to implement to manage weight loss. In my future articles I will address the psychological issues of food and how to manage the cravings.
Here is a shake recipe to incorporate all of the above.
Blueberries - half cup
Cucumber - one cup
Watermelon - one cup
Celery - quarter cup
Ginger - half thumb size
Grind everything until very smooth, in 8oz water. Pour in a glass, add ice cubes and enjoy and beat the summer heat.
