I possess got explained inwards diverse posts why this see does non seem to survive right (1, 2, 3), in addition to why, after extensive research, the insulin hypothesis of obesity lost steam past times the belatedly 1980s. However, I latterly came across ii experiments that tested the hypothesis every bit straight every bit it tin survive tested-- past times chronically increasing circulating insulin inwards animals in addition to standard nutrient intake in addition to torso weight and/or torso fatness. If the hypothesis is correct, these animals should gain fat, in addition to maybe consume to a greater extent than every bit well.
In the outset study, published inwards 1980 past times Dr. Dennis A. Vanderweele in addition to colleagues, rats were implanted amongst mini-pumps delivering insulin at a steady charge per unit of measurement throughout the 24-hour interval in addition to black for vii days (4). They tested iv different doses: 0, 1, 2 in addition to half dozen units per day, in addition to measured nutrient intake in addition to torso weight. This is a model of chronically elevated insulin reminiscent of what is seen inwards insulin-resistant people.
They establish that all doses of insulin reduced torso weight gain, only alone the 2 unit of measurement dose was statistically significant. They speculated that the half dozen unit of measurement dose was less effective at reducing weight gain because it was sufficiently high to movement hypoglycemia (low blood sugar), which is a rigid trigger for nutrient intake. Total nutrient intake was suppressed at all doses past times insulin every bit well, only this was plainly non due to illness. The authors conclude:
They placed mice on a fattening diet (HFD) amongst or without Cpd2 added to the food, so measured nutrient intake, torso weight in addition to torso fatness over a half dozen calendar week period. Here is what they observed when they measured torso fatness:
Consistent amongst the previous study, Cpd2 opposed weight in addition to fatty gain, in addition to suppressed nutrient intake every bit well, without causing illness. Glucose tolerance in addition to blood glucose levels were also improved inwards the Cpd2-treated group.
It is worthwhile to banking corporation complaint that at that spot are also studies showing that daily injections of long-acting insulin atomic number 82 to torso fatty gain inwards rodents over fourth dimension (6a, 6b, 6c). However, these studies used high doses of insulin that resulted inwards hypoglycemia, which every bit I mentioned inwards a higher house is a rigid trigger for nutrient intake in addition to causes a major hormonal reply (the "counter-regulatory response"). That's the unique matter most the studies discussed above-- they investigated the deport on of insulin signaling on torso fatness without involving hypoglycemia, a province of affairs that is to a greater extent than akin to what is observed inwards people amongst elevated fasting insulin due to insulin resistance.
The Final Nail
Contrary to what the insulin hypothesis of obesity predicts, chronically elevated insulin if anything seems to oppose weight in addition to fatty accumulation inwards beast models. This probable involves insulin's activity inwards the encephalon to constrain torso fatty accumulation.
The evidence suggests that:
We need a ameliorate hypothesis to explicate why low-carbohydrate diets movement fatty loss inwards many obese people, in addition to nosotros definitely need a ameliorate hypothesis to explicate why obesity arises inwards the outset place. An choice hypothesis, that insulin opposes fatty gain through its activity inwards the brain, is plausible in addition to has received back upwards from a multifariousness of lines of evidence. Insulin resistance inwards the brain, leading to reduced insulin signaling inwards neurons, has been documented inwards beast models of obesity, in addition to probable contributes to fatty accumulation. Therefore, the 'insulin hypothesis of obesity' that makes feel is that a reduced insulin (and especially leptin) signal inwards the encephalon contributes to fatty gain.

Tips Today Insulin As Well As Obesity: About Other Blast Inwards The Coffin
There are several versions of the insulin hypothesis of obesity, only the versions that are most visible to the public generally country that elevated circulating insulin (whether acuate or chronic) increases torso fatness. Some versions invoke insulin's effects on fatty tissue, others its effects inwards the brain. This see has been used to explicate why low-carbohydrate in addition to low-glycemic-index diets tin atomic number 82 to weight loss (although frankly, glycemic index per se doesn't seem to possess got much if whatsoever deport on on torso weight inwards controlled trials).I possess got explained inwards diverse posts why this see does non seem to survive right (1, 2, 3), in addition to why, after extensive research, the insulin hypothesis of obesity lost steam past times the belatedly 1980s. However, I latterly came across ii experiments that tested the hypothesis every bit straight every bit it tin survive tested-- past times chronically increasing circulating insulin inwards animals in addition to standard nutrient intake in addition to torso weight and/or torso fatness. If the hypothesis is correct, these animals should gain fat, in addition to maybe consume to a greater extent than every bit well.
In the outset study, published inwards 1980 past times Dr. Dennis A. Vanderweele in addition to colleagues, rats were implanted amongst mini-pumps delivering insulin at a steady charge per unit of measurement throughout the 24-hour interval in addition to black for vii days (4). They tested iv different doses: 0, 1, 2 in addition to half dozen units per day, in addition to measured nutrient intake in addition to torso weight. This is a model of chronically elevated insulin reminiscent of what is seen inwards insulin-resistant people.
They establish that all doses of insulin reduced torso weight gain, only alone the 2 unit of measurement dose was statistically significant. They speculated that the half dozen unit of measurement dose was less effective at reducing weight gain because it was sufficiently high to movement hypoglycemia (low blood sugar), which is a rigid trigger for nutrient intake. Total nutrient intake was suppressed at all doses past times insulin every bit well, only this was plainly non due to illness. The authors conclude:
1) insulin limits repast size when blood levels are modestly elevated for prolonged periods of fourth dimension inwards the rat, 2) this decrease inwards repast size is non compensated for past times an increment inwards repast frequency and, hence, full daily nutrient ingestion in addition to torso weight gain are reduced, in addition to 3) this outcome appears to survive a heightening of satiety rather than an induction of illness.The mo study, published inwards 2002 inwards Nature Medicine past times Dr. Ellen L. Air in addition to colleagues, took a different approach (5). The authors used a drug called Cpd2, which mimics the outcome of insulin on the insulin receptor, only tin survive taken orally rather than past times injection (6).
They placed mice on a fattening diet (HFD) amongst or without Cpd2 added to the food, so measured nutrient intake, torso weight in addition to torso fatness over a half dozen calendar week period. Here is what they observed when they measured torso fatness:
Consistent amongst the previous study, Cpd2 opposed weight in addition to fatty gain, in addition to suppressed nutrient intake every bit well, without causing illness. Glucose tolerance in addition to blood glucose levels were also improved inwards the Cpd2-treated group.

The Final Nail
Contrary to what the insulin hypothesis of obesity predicts, chronically elevated insulin if anything seems to oppose weight in addition to fatty accumulation inwards beast models. This probable involves insulin's activity inwards the encephalon to constrain torso fatty accumulation.
The evidence suggests that:
- Experimentally preventing the increment inwards circulating insulin that occurs on fattening diets does non modify the class of fatty gain inwards rodents or dogs (7).
- Experimentally elevating circulating insulin past times creating liver insulin resistance does non atomic number 82 to fatty gain inwards rodents (8).
- Experimentally increasing circulating insulin past times infusing it straight into the blood does non movement fatty gain inwards rodents, only instead makes them leaner (above).
- Roughly a quarter of obese humans possess got normal circulating insulin in addition to normal insulin sensitivity ("metabolically healthy" obese) (9).
- In Pima (Akimel O'odham) native Americans, 1 of the most obesity-prone populations inwards the world, in addition to sure enough other populations, insulin resistance in addition to higher insulin secretion consistently predict less torso fatty gain over fourth dimension (10, 11, 12, 12a, 12b). This has non been observed inwards all populations, only the fact that it occurs inwards roughly casts farther doubtfulness on the see that elevated insulin is a fundamental contributor to fatty gain.
We need a ameliorate hypothesis to explicate why low-carbohydrate diets movement fatty loss inwards many obese people, in addition to nosotros definitely need a ameliorate hypothesis to explicate why obesity arises inwards the outset place. An choice hypothesis, that insulin opposes fatty gain through its activity inwards the brain, is plausible in addition to has received back upwards from a multifariousness of lines of evidence.
