I found this delicious animated video via http://www.losingthewheatbelly.blogspot.ca/
Short and sweet.
Of course, not everyone needs to adopt a LCHF lifestyle in order to have a healthy metabolism and enjoy a healthy body weight without struggles with hunger. Some people can handle a higher intake of carbohydrates, particularly if they focus on carb foods with a low glycemic index. Long term success comes from taking the time and effort to adjust your lifestyle specifically for you.
Also, there are some people who find, even after they are very well adapted to a LCHF eating pattern, that they do need to pay some attention to calories (e.g. Ellen ) – but without the suffering from hunger that they had previously without a LCHF approach).
One other thing to point out relates to the comment in the video about human body fat. Human body fat is composed mostly of MUFA (mono-unsaturated fatty acids) and SFA (saturated fatty acids), with a bit more MUFA than SFA. Of course, there will be some variability between people in this. You can read about this, and review a good table showing the fatty acid content of various foods, fats and oils in the book I am constantly recommending “The Art and Science of Low Carbohydrate Performance” by Jeff Volek, PhD, RD and Stephen Phinney, MD, PhD.
Quoting from that book:
“Factoid: A 50:50 mixture of butter and olive oil approximates the composition of triglycerides typically found in human body fat.”
The web site mentioned in the video is lchf.se which looks like a terrific site, if you are up to reading Swedish.
