I know that there are people out there reading this blog that are a lot more intelligent than me and also more familiar with science. However, here is how I read this research:
- In a previous experiment these researchers found that a high fat low-carb diet was inflammatory;
- They came up with the hypothesis that this inflammation was due to oxidative stress;
- They decided to test this idea by putting some overweight people on a high fat / low carb and seeing what happened when some of them were given antioxidant supplements;
- The diet worked in that the overweight people lost weight;
- The antioxidant supplements did not make the diet more effective in terms of weight loss;
- The diet caused a reduction of some but not all markers of inflammation;
- A role for oxidative stress in causing inflammation was not confirmed.
So, a high fat diet can make you lose weight and reduces some markers of inflammation?
Of course the abstract alone only prompts more questions - it is not clear what the diet consisted of in terms of macro ratios or types of fat for example. Plus to lose weight you need to reduce calories of course.
I am also reminded of previous posts that questioned the value of antioxidant supplements, e.g.,
Antioxidants do more harm than good
A ketogenic diet can in itself be an antioxidant
