Fat and Diabetes

Submitted by on 17 December, 2021 – 4:33 pm

Too much junk food could put folk on a fast track to diabetes, a new study advises.  Only one month on a junk food diet was ample to alter the capability of fat cells to reply to insulin, analysts from Linkping College in Sweden reported online Apr thirty in Molecular Medication .  The incapacity to reply correctly to insulin, called insulin resistance, is a trademark of type two diabetes.

Cell biologist Peter Strlfors of Linkping University got the idea to put folk on a junk food diet from the 2004 documentary Super Size Me, in which a man eats a steady diet of McDonald’s food and grows heavier and increasingly sick. Strlfors hired 18 lean young folks to go on a junk food binge. At the start of the experiment, the volunteers averaged a trim body mass index of 22.4. Body mass index, or BMI, is figured out from an individual’s weight and height and indicates the degree of blubber, typically. To follow a calorie-laden calorie-heavy diet, volunteers ate 2 junk food meals a day for a month. They also limited activity to five thousand steps a day 1/2 of the endorse quantity of daily exercise. Before the experiment started, the analysts removed fat from under the skin of the volunteers’ bellies.

Or attempted to the volunteers were so lean that analysts managed to get sufficient fat for research from only 6 folks. Bingeing on junk food about tripled the volunteers’ daily calorie intake, the team reports. By the end of the month, volunteers had gained a mean of ten % of their body weight, enlarging BMI to 24.3, still in the standard range.

Usually the volunteers gained about twelve to fifteen pounds, 7.5 pounds ( 3.4 kilograms ) of which was fat. Fat cells picked up from the volunteers at the end of the month showed a small amount of insulin resistance, the analysts found. The bingers were more insulin resistant at the end of the month than are most healthy folk twice their age, though still not as resistant as diabetics, Strlfors claims. “Just the process of changing has effects at both ends,” he asserts. A huge increase in calorie intake and quick weight gain are extremes that potentially don’t reflect real-world scenarios, claims Marc Hellerstein, a metabolic analyst at the University of California, Berkeley.

And fat, or gross tissue, isn’t the main tissue touched by insulin resistance. Muscle and liver are influenced more, he asserts. Still, even given what he sees as the study’s weaknesses, Hellerstein called it a fascinating experiment that shows that weight gain, even in the short term, can affect metabolism. The study failed to address whether more exercise could have protected against some of the rise in insulin resistance in the face of weight gain.

After a month of bingeing on junk food, the volunteers returned to their previous diets, exercise habits and, at last, leaner BMIs, Strlfors claims. The volunteers’ insulin sensitivity also reverted to normality and he is saying he does not expect any lasting harm to come from the month-long fast food bender. The analysts hope to increase the study to incorporate more volunteers and get a better image of how gaining weight changes the body’s reply to insulin.
