Sugar is the root cause of the obesity epidemic spreading around the globe and this great Australian documentary from ABC Catalyst explains how our body reacts to sugar and carbs. These are 18 min you really need to watch!
You will hear comments from obesity Professor Michael Cowley who explains how insulin is the main hormone which stores fat in the fat cells and eating carbohydrates will cause your insulin levels to stay high (makes you fat).
Professor Robert Lustig from the University of California resembles eating sugar with coating a steak with a sugary barbecue sauce. The sauce helps the steak to brown faster and the same thing is happening inside us when we eat sugar; we age faster. Prof Lustig says that if you had a glass of fruit juice this morning, it caused you to age seven times faster.
Overall I think these are 18 minutes really well spend watching. If you still don’t want to look at it then here’s the main insight; sugar and carbohydrates makes us fat and we should limit our intake of these substances. Instead eat more protein and fat.
Maybe not hot-of-the-press-news but I just saw Michael MosleysBBC documentary about fasting. Michael sets out to investigate if periodic fasting can slow down ageing and give you a healthier lifestyle.
One of the latest diet trends is intermittent fasting; short periods of fasting alternated with non-fasting. The fasting periods can be everything from 12h to a couple of days. One of the more extreme versions is Alternate Day fasting (ADF). The idea is that you starve yourself one day and gorge the next. Another version is the 5:2 diet. In 5:2 you eat normal for five days and then a calory restricted diet for two days (600 calories for men and 500 for women). Michael tries both diets but in the end get hooked on the 5:2 diet.
The force of hunger
Even though these kind of diets seem to work, at least for Michael, I’m slightly sceptical to whether this is a sustainable lifestyle you can maintain in the long run. Hunger is a strong force and I wouldn’t want to face starving for two days every week.
Personally I eat a low carb diet with plenty of protein, mainly from vegetable sources but also meat and fish, as well as above ground vegetables and healthy fat, (real butter, olive- and coconut oil).
Have a look at the documentary and see for yourself. Is fasting something you would try or already are practicing?
