A new study was published in TheLancet by Harvard scientists doing a systematic review of 53 Randomized Controlled Trials of different types of diets to try to find a correlation between Low Fat vs Low Carb diets and their effects on weight loss. They wanted to know what was the best diet to lose weight on. And to be honest, their results are not all that interesting.
The review encompassed 68128 subjects and their diets. It showed that after one year, low carb diets lost about 3 pounds more after a single year than low fat diets. The media had a field day with this, saying that Low Carb diets are the only one to use to losing weight effectively. This is not true, the same study noted that low fat diets still allowed 10 more pounds to be lost annually than a regular diet. So the main difference between low-fat and low-carb diets are only about 3 pounds, according to this research, and should not be culturally significant, even if it is scientifically “significant” (the word “significant” in science does not mean what society thinks it does.)
There were also a lot of differences per each study, with diets altering in fat content from 10% to 30% and the like. The authors did acknowledge this, however. But it is good to know that there are limitations to many studies, including these ones.
The main thing is simply trying to lower caloric intake. In terms of weight loss, lowering the consumption of added sugars, saturated fats, calorie laden beverages, and increase the consumption of good fats, fiber, and vegetables, is the real key to weight loss. Diet matters MUCH more than exercise in getting you to lose weight, not to say that exercise isn’t the least bit important, it most certainly is.
So it is about time we stopped nickpicking over trivial differences of 3 pounds in regards to carbs vs fat, and focus more on eating whole grains, leafy greens, and lean meats, and consuming less calorie dense but nutritionally deficient foods, such as soda, or fried foods. If this study has taught me anything, it is that this war between high fat vs high carb should not even exist. Moderation and healthy eating should matter first and foremost in terms of a healthy diet.
