Low fat and diabetes

In a recent study, over 8 weeks, it was suggested that reducing fat could help decrease the risk for type 2 diabetes more so than reducing carbs for 69 overweight people.

They apparently compared a low carb diet to a low fat diet.  I guess they were suggesting that by reducing fat intake, you can still enjoy being fat and not increase your risk of type 2 diabetes.

The problem is that the low carb numbers in this study were set at 43% of daily carb intake?  So on a 2,000 calorie diet, 43% of the carb intake would equate to about 215 grams of carbs by my math?  And that’s supposed to be low carb?

How about under 100 grams of carbs?  Or maybe under 60 grams of carbs? That’s what I call low carb.  200 grams of carbs per day is NOT low carb at all.

“At eight weeks, the group on the lower-fat diet had significantly higher insulin secretion and better glucose tolerance and tended to have higher insulin sensitivity,” the study’s lead author said.

Higher insulin secretion?  Now we know that one of insulins job is to move fat into fat cells.  Does it make any sense health-wise to eat a diet that actually increases insulin secretion?  Unless you were already diabetic and uncontrolled / medicated?  I suspect based on this study, a high carb, high fat diet would make for a really bad diet.  I would add that if you are eating a high carb diet, then you probably do want to cut the fat.

Of course, it would have been interesting to have kept the carb count the same and varied the protein intake.  Or kept the fat content the same and vary the protein intake.  Might have gotten similar results?  Who knows.

The real problem is jumping to conclusions on small amounts of data that could entirely erroneous and generalizing the results.

For example, there was a study showing that over a years time, people eating a high carb diet were happier than those on a low carb diet.  But the glaring thing about that was the total weight loss (not to mention 1 out 5 people were on anti-depressants).  They said the average weight loss was roughly the same in both groups over a year.  Now I know for a fact that if you’re obese and eat under 40 grams of carbs per day for a year, you’re going to lose more than 13 pounds.  So what’s that tell you?  These people weren’t following the diet for the entire year?  Probably the case.  Which would skew the results.

So give it another couple months and another study will come out showing something different.

And while I’m totally biased towards low carb, at some point, you have to find the diet right for your body, based on how you feel, how you look, how much energy, and mental clarity and focus it gives you.
