A study on increasing the intake of dietary fats did not result in weight gain according to research sponsored by the American Diabetes Association and the National Institutes of Health.
Unraveling A Recent Press Release
If you research low carb high fat diets online you’ll likely bump into poorly written articles that cite the study below. Those articles also state that a high fat diet will result in insulin resistance. The only way these ‘reporters’ could come to this conclusion is by skipping ahead to the research study’s conclusion. Or copying each others’ articles. Or both.
This shabbiness in reporting and certainly these conclusions are a stretch by any legitimate scientific standard.
Inconsistencies In The Trial
The original call for the study in March 2013 was to conduct an “in depth research investigation” that would be funded by the ADA and NIH. (reference: https://www.vtnews.vt.edu/articles/2013/03/032013-fralin-diabetesgrant.html).
It doesn’t appear the team hit their mark when they published the proposed three year study, just two years later. (reference: http://onlinelibrary.wiley.com/enhanced/doi/10.1002/oby.21031/ March 27, 2015)
Small and Elite Study Subjects
The published study cites a mere 5 day trial.
With only 12 subjects.
All of which were healthy, young college males.
No Real Evidence
How far this team had to stretch to reach their final conclusion is beyond the scope of this article. The published paper focuses on insulin resistance and states “Our findings provide evidence…” even though 5 days and such a small sample is not an indicator for legitimate research.
The Only Conclusion of Value
What is of value to high fat dieters however, is that when these young and healthy men increased their average 30% fat diets to 55% – changing nothing else about their lifestyle – they did not gain weight.
And while that tidbit of information is one that many high fat dieters could have easily shared and documented – we don’t gain weight when we eat fat, we lose it – this research team seems content to take funding from agencies that will continue to promote pharmaceuticals while justifying their bloated salaries.
From this we can surmise (not conclude) that it may only take five days of eating a high-fat diet to alter metabolic function – especially so if you’re a young and healthy college male.
Findings of the results of a recent study performed by Matt Hulver (associate professor of human nutrition, foods, and exercise at the Virginia Tech College of Agriculture and Life Sciences) and team, showed that the manner in which muscle metabolizes nutrients is altered within five days of eating a high-fat diet. This is the first study of its kind that postulates a change can happen that quickly. See the online version of the journal “Obesity” for more results of this research.
Hulver has been quoted as saying “…all it takes is five days for your body’s muscle to start to protest.”
The long believed theory that a change in how muscle tissue processes nutrients might lead to long-term problems such as weight gain, obesity, and other health issues is now up for debate as the study only shows that “…our bodies respond dramatically to changes in diet in a shorter time frame than we have previously thought,” said Hulver.
“If you think about it, five days is a very short time. There are plenty of times when we all eat fatty foods for a few days, be it the holidays, vacations, or other celebrations. But this research shows that those high-fat diets can change a person’s normal metabolism in a very short time frame.”
The study was only tested on healthy college-age students. The protocol was to increase fat intake from 30-55% for five days by tracking the fat macro-nutrient of each students’ diet. Students consumed sausage biscuits, macaroni and cheese, and meals that included ample amounts of butter. Their overall caloric intake did not change from their previous diets.
After five days, muscle samples were collected and while the results showed that glucose was metabolized differently on a high fat diet, the students did not gain weight or show any changes in insulin resistance (metabolic dysfunction).
The Department of Human Nutrition, Foods and Exercise research team included Matt Hulver (credentials cited above), Associate Professor Brenda Davy, Professor Kevin Davy, Assistant Professor Madlyn Frisard, and Research Assistant Professor Ryan McMillan. Four former grad students also contributed to the research.
