Normal non-pathogenic enteric bacteria may play a key role in diet-induced adiposity because adult germ-free GF mice have less body fat and do not become obese when fed a HFD . Seriously, one of my life long dreams is to see an article of mine in there. Pigs fatten on a grain diet.
However, responses of perivascular adipose tissues to high fat feeding have not been examined. Instead, the oxidation of dietary fat was suppressed and fat storage thereby increased.
I mean seriously, here are just a few studies, along with their data 121314 Furthermore, some SCFAs, especially propionic acid, have been shown to lower cholesterol levels  and to have a beneficial effect on glucose and lipid metabolism .
Recent evidence indicates that the periadventitial adipose depot is a functional component of the vasculature, exerting paracrine influences on blood vessel contractility 11 Here are the relevant biochemistry pathways just to show your the giant cluster that is DNL.
Now as science is a methodology to test hypotheses, and all of these are hypotheses and they have been tested, the data is out there. Potential mechanisms for this effect include 1 an improved capacity for energy harvest and storage and, 2 enhanced gut permeability and inflammation.
More on this topic to follow. While reactive fibroblasts and inflammatory cells in the adventitia have been the focus of extensive investigations 67very little is known about perivascular adipocytes that reside at the adventitial border of atherosclerosis-prone blood vessels.
Similarly, the SCFA receptor GPR43 is likely to be involved as it has been reported that the gut microbiota suppresses insulin-mediated fat accumulation via this receptor Content may be edited for style and length.
Here is a meta-analysis that we discussed in an earlier post HFD induced the growth of Enterobecteriaceae and the production of endotoxin in vitro. The case is pretty much closed on that front. We highlight the most important recent advances linking HFD-induced dysbiosis to obesity, explore the possible mechanisms for this effect, examine the implications for disease development, and evaluate the possibility of therapeutic targeting of the gut microbiome to reduce obesity.
Nowadays, it is widely accepted that metabolic syndrome is associated with low-grade systemic inflammation, despite the fact that the molecular origin of the inflammation is unknown .
Other components of the metabolic syndrome are obesity, high blood pressure and high fasting blood glucose levels . At the end of 8 weeks, mice were anesthetized followed by blood draw for biochemical assays. Thus, the addition of excess carbohydrate energy to a mixed diet so that total energy intake exceeded total energy expenditure TEE increased body fat stores, but not by conversion of the carbohydrate to fat.
The high-fat diet primarily reduced formation of SCFAs but, after a longer experimental period, the formation of propionic and acetic acids recovered. On the basis of this presumed role, inhibitors of de novo lipogenesis [such as — hydroxycitrate, an inhibitor of ATP citrate pro-S -lyase] have received attention as potential therapeutic agents for obesity and hyperlipidemia.
Isolation and differentiation of human preadipocytes Tissues were minced and digested with collagenase type I Worthingtonafter which isolation and culture of preadipocytes was performed as previously described 18 Halade and colleagues found that the obesity-generating diet and aging led to neutrophil swarming and an altered leukocyte profile after heart attack.
Journal Reference: False Fat is more satiating than carbohydrates: Similar phylum-level shifts were reported following high-fat and high-sucrose feedings 4. Mechanisms Linking High-Fat-Diet-Induced Dysbiosis to Obesity The consequences of HFD-induced dysbiosis are potentially significant as the majority of evidence links this to the promotion of obesity and ensuing metabolic disorders.
Perivascular adipocytes are more irregularly shaped and smaller in size than perirenal or subcutaneous adipocytes. Moreover, high fat feeding induces inflammation of visceral adipose tissues 20which may contribute to insulin resistance and dyslipidemia. Results Morphological features of perivascular adipocytes Figure 1 shows representative images of coronary perivascular PVperirenal PR and subcutaneous SQ adipose tissues.
Let us see what we can learn from the data.
Results HFD induced macrophage infiltration and inflammation in the adipose tissue, as well as an increase in the circulating proinflammatory cytokines. That is the amount that de novo lipogenesis contributes to to fat balance in a hypercaloric state.
Now, scientists have shown what happens to colon tissue when mice are fed such a diet: No mechanistic evidence exists to support this idea See the two studies shown above.
False You eat less when you eat high fat meals: Objective To investigate whether dietary fibres, giving rise to different SCFAs, would affect metabolic risk markers in low-fat and high-fat diets using a model with conventional rats for 2, 4 and 6 weeks.
Moreover, two weeks of high fat feeding caused further reductions in adipocyte-associated gene expression, while up-regulating pro-inflammatory gene expression, in perivascular adipose tissues. We show that human coronary perivascular adipocytes exhibit a reduced state of adipocytic differentiation as compared with adipocytes derived from subcutaneous and visceral perirenal adipose depots.
Results and Discussion Fermentable dietary fibre decreased weight gain, liver fat, cholesterol and triglyceride content, and changed the formation of SCFAs.
· Importantly, the high-fat diet did not have harmful effects on cholesterol levels. In fact, the participants saw a lowering of the blood fat called ancientmarinerslooe.com: Sid Kirchheimer.
The low-carb, high-fat diet, known as a ketogenic diet or the keto diet, was found to begin a process that alleviates brain inflammation. The low-carb, high-fat diet, known as a ketogenic diet or the keto diet, was found to begin a process that alleviates brain inflammation.
The Truth About High Fat Diets Posted on April 16, August 31, by Brad Dieter, PhD For some strange reason there has been a pendulum swing from low fat to high fat diets over the last decade.
It is known that diet interacts with gut microbes to calibrate the body's immune defense capacity. The UAB-led researchers examined this further, with regard to aging and a high-fat diet.
