Furthermore the study includes a table of motivations for pursuing veganism. Only a measly 1-3% of participants had motivations that were purely ethical in nature. While most motivations were health related. So, it seems like people are generally going on plant-based diets for health related reasons, and abandoning the diets without generally suffering health related costs. This isn't the only reason the question is stupid. Plenty of health promoting behaviours have high recidivism rates, such as exercise.

The mechanistic case for the IMCL hypothesis was first outlined in the late 1990s with two small studies by Jacob, et al. and Perseghin, et al., which discovered relationships between IMCL and insulin resistance in T2DM-free subjects who were born of parents with T2DM [[1](https://pubmed.ncbi.nlm.nih.gov/10331418/)][[2](https://pubmed.ncbi.nlm.nih.gov/10426379/)]. In these experiments, the offspring of those with T2DM were subjected to the gold-standard measure of whole-body insulin sensitivity, the hyperinsulinemic-euglycemic clamp test (HEC). It was discovered that there was an inverse association between IMCL and insulin sensitivity, which led researchers to suspect that perhaps this biomarker was relevant to the pathophysiology of T2DM.

Fast forward to 2004, and another small study from van Loon, et al. would introduce the hypothesis' first paradox [[3](https://pubmed.ncbi.nlm.nih.gov/15165998/)]. In this experiment, muscle biopsies and less precise (but still adequate) measures of insulin sensitivity were deployed in an investigation of subjects who were either sedentary, afflicted with T2DM, or who were trained athletes. The study found that the IMCL concentrations of IMCL were actually statistically significantly higher in athletic subjects compared to either sedentary or T2DM-afflicted subjects. Yet, the athletic subjects did not suffer from impaired insulin sensitivity or the hyperglycemia that is characteristic of T2DM.
![][image2]

Researchers Coen and Goodpaster attempted to reconcile the findings in 2012 [[4](https://pubmed.ncbi.nlm.nih.gov/22721584/)]. They hypothesized that IMCL behaves differently in the context of T2DM, and that while IMCL serves as a fuel source in athletic subjects, in sedentary subjects with T2DM the IMCL seems to produce more disruptive mediators like ceramides and diacylglycerols. However, the authors tend to play fast and loose with their causal inferences, often citing animal research to buttress clear implications about what holds true in human beings. In fact, the majority of their supporting evidence is derived from mice, despite mice generally being poor facsimiles for human subjects [[5](https://pubmed.ncbi.nlm.nih.gov/31307492/)].

![][image3]

[image3]: /blog/sweetdeception/image3.png
However, it's unclear what the clinical significance of this finding is, considering that the fructose-based intervention resulted in significant overfeeding and only increased fasting glucose by 5% compared to the glucose-based control. Seems like the authors tried pretty damn hard to induce a T2DM phenotype feeding fructose to subjects, and were ultimately unable to achieve that. In fact, they weren't really able to get close. Even the oral glucose tolerance test results, though far from ideal, showed an altogether normal blood glucose curve for the fructose group.
![][image4]

The second trial was unremarkable, and suggested that fructose consumption may decrease energy expenditure over time when isocalorically compared to glucose. Again, it's interesting, but it's far from demonstrating a cause and effect relationship between T2DM and sugar. The third trial is a bit more complicated to unpack. Basically, subjects were split into two groups, 25% of calories as either fructose or glucose as parts of eucaloric diets over 10 weeks, with the primary endpoints beings measures of liver function. Overall, the results of the trial suggest a significantly detrimental effect of fructose compared to glucose on a number of markers related to liver function. However, it's slightly more complicated than that.
While it's true that the treatment effect showed a benefit of glucose over fructose, it's also true that the marker of liver function that was negatively perturbed was gamma-glutamyl transferase (GTT). The change in GGT was also barely statistically significant compared to baseline, while markers such as aspartate aminotransferase (AST) and alanine aminotransferase (ALT) showed a non-significant decrease. Glucose showed greater reductions that were barely statistically significantly different from that of fructose.

Other than that, fructose did seem to increase uric acid levels to a statistically significant degree, making fructose a potential aggravating factor for conditions such as gout. But again, this is a far cry from causally linking fructose consumption to the development of T2DM, especially since fructose seemed to do nothing particularly interesting to markers of liver function. It is true that sugar intake is severely negatively associated with health outcomes [[13](https://pubmed.ncbi.nlm.nih.gov/34444794/)]. However, while this is a consistent finding, clinical trials on sugar consistently fail to demonstrate a connection between sugar intake and the development of T2DM.

To be clear, there was a clear distinction between remission and reversal, as defined by the authors. Remission was a much more robust measure of traction against T2DM than reversal, even though it sounds like the latter is stronger than the former. Remission was defined in two parts; partial remission and complete remission. Partial remission was defined as "sub-diabetic hyperglycemia of at least 1 year duration, HbA1c level between 5.7-6.5%, without any medications (two HbA1c measurements)" and complete remission was defined as "Normoglycemia of at least 1 year duration, HbA1c below 5.7%, without any medications (two HbA1c measurements)".

There was however, a direct association between IHL and EGP. Although this trial was not controlled, it certainly doesn't produce results expected on the IMCL hypothesis, and it lends further credence to the TCH. Additionally, many markers of T2DM subsequently improved, such as plasma glucose, hemoglobin A1c (HbA1c), and even TGs, with the changes being -2.3mmol/L, -1.9%, and 0.4mmol/L, respectively.

It can also be inferred that there was a meaningful increase in insulin sensitivity, given the fact that plasma glucose dropped despite the same amount of insulin being produced by subject. Essentially, glucose disposal per unit insulin went up, implying that insulin signalling had improved.

In the second study by Petersen, et al., eight subjects with T2DM were compared to 10 healthy volunteers in a non-randomized weight loss trial over an average of seven weeks. Essentially, subjects were followed up until normoglycemia was achieved, so not every subject was subjected to the same amount of weight loss for the same time period. In this time, body weight dropped by an average of 8kg in the T2DM group. This was marked with commensurate drops in plasma glucose, plasma insulin, and TG, at -2.4mmol/L, -108pmol/L, and -0.3mmol/L, respectively.

The most interesting and surprising finding was that there was no significant change in IMCL despite weight loss. But, subjects did end up achieving normoglycemia and near normal insulin sensitivity as determined by a HEC. However, much like the previous study, insulin sensitivity was directly associated with IHL reduction. Once again, this flies in the face of the IMCL hypothesis, and offers further support for the TCH as the T2DM approached nearly normal levels of IHL. Although neither of these papers directly test for evidence of the sugar or oxidation hypotheses, it should be noted that both of these trials involve the consumption of both sugar and most likely animal products.

In terms of other T2DM markers, such as plasma glucose, the response to the diet was heterogeneous among participants with long-term T2DM. Some showed similar responses to those in the short-term group and some responded slowly. By the end of the study, 87% of the short-term group and 50% of the long-term group achieved non-T2DM fasting plasma glucose levels. HbA1c levels also decreased in both groups, with a more significant reduction observed in the short-term group. However, there was an unforeseen result about half of subjects did not respond to the treatment at all, which was not expected given nearly all previous research.

Given these results and Dr. Taylor's previous characterization of the PFT concept, the most likely hypothesis seemed clear these people just needed to lose more weight, which we'll get to later. For now, there was enough evidence of the effectiveness of weight loss for T2DM treatment that Dr. Taylor and his colleagues decided it was time to test the efficacy of the treatment in a real-world outpatient scenario. A cluster-randomized experiment was designed and undertaken, and would come to be known as the Diabetes Remission Clinical Trial (DiRECT) [[31](https://pubmed.ncbi.nlm.nih.gov/29221645/)].

The DiRECT trial involved 298 subjects across 49 primary care practices (or clusters) randomized two groups, a control group receiving the standard of care for T2DM management, and the treatment group receiving a three stage program: stage one, total diet replacement; stage two, food reintroduction; phase three, weight maintenance. For the first stage, the treatment group received a liquid diet consisting of four packets of meal replacement formula, which totaled around 825-853 kcal/day for three to five months (depending on patient-specific goals). For the second stage, after subjects completed the first weight loss phase of the trial, food was gradually reintroduced over a period of two weeks to two months. During the last stage, patients were followed up over the course of around a year. The results were encouraging.
