The Muscle/Fat Paradox
The perfect body composition: low body fat, plenty of rock-hard muscle. It's the goal of everyone who hits the gym. But it's difficult, even if you're working hard.
Here's the paradox: You need to eat a lot of quality foods to build muscle, and that includes a good amount of carbs. But unless you're genetically gifted, some of that food is stored as body fat. Maybe a lot of it.
So what do we do to lose the excess fat? We diet. And that often includes lowering carb intake. But then muscles look flat, performance decreases, and muscle gains slow down or come to a halt. What's worse, strict low-carb diets "teach" your body that it can't handle carbs. Carbs begin to be preferentially stored as fat, instead of being used to fuel workouts and build muscle.
So the average lifter is left with a choice: get bigger but softer, or get lean but also kinda frail looking.
It Doesn't Have To Be That Way
Indigo-3G selectively partitions nutrients so that food turns to muscle, rather than just being stored as fat.* The result?
- Dramatically improved body composition.*
- The ability to eat more to build muscle without getting fat.*
- The ability to lose fat without excessive dieting.*
- The ability to enjoy carbs again without worry.*
Helps Food Turn to Muscle*
Cyanidin 3-glucoside (C3G) — a naturally occurring compound — precisely controls carbohydrates to help the food you eat turn to muscle.* Research has proven C3G's effects on insulin signaling, selective insulin sensitivity, glucose and nutrient management, and its direct effect on fat and muscle cells.*
Indigo-3G helps your body function perfectly for building muscle without the fear of gaining fat, even while on a bulking diet, making the body-building process a whole new ballgame.* No more depriving yourself of the optimal nutrition for building muscle because "your body can't handle the carbs" — because now it can.*
Indigo-3G acts as a nutrient partitioning agent — meaning it maximizes carbohydrate uptake in muscle, releases and burns fat, and prevents the storage of fat.* That makes Indigo-3G the ultimate body-transformation agent.*
How C3G Affects Cells
Fat Cells — C3G up-regulates gene expression for fat oxidation (fat burning) and down-regulates gene expression for fat storage. The oxidation of fatty acids increases further, directly through the release of adiponectin.* The overall effect is that fat cells begin to shrink.* The reduced inflammation also decreases the size of fat cells and disgorges the excess water associated with the inflammatory process, leading to a less bloated and squishy feeling to the fat under the skin. In short, Indigo-3G repairs dysfunctional fat cells.*
Muscle Cells — Insulin sensitivity of muscle cells increases.* This enhances insulin signaling and glucose and nutrient uptake, along with enhancing glycogen synthesis, which drives glucose and nutrients preferentially into muscle rather than shuttling them off to fat storage.*
The Most Effective Delivery System*
There are other C3G products on the market, but they have two big problems. First, many supplement makers just shove a little C3G into a capsule without using a proper delivery system that makes it bioavailable or usable in the body.* Second, most C3G supplements are under-dosed.* C3G is expensive, and other products just don't provide enough of it to give you a noticeable effect.*
But Indigo-3G is different. The formula contains a self-microemulsifying delivery system that substantially enhances C3G's potency, bioavailability, and stability.* Most importantly, Indigo-3G provides the amount of C3G required for maximum results.*
How to Get the Greatest Effects From Indigo-3G
Here are the important things to keep in mind and what to expect:
- Enhanced Carb Uptake:* You can't utilize something you don't consume. So, if you don't consume ample supplies of carbs around your workout, you'll greatly diminish muscle mass gains. In contrast, low-carb diets make your muscles feel and appear flat. This "flatness" is due to low intramuscular pressure, which is associated with a catabolic (muscle wasting) state. Keeping muscle bellies full, by including ample amounts of carbs, means that you're not losing muscle and well on the way to building it.*
- Increased Muscle Gains and Fat Loss:* Most users will begin noticing changes in body composition within the first week or two. Some have even reported substantial muscle gains and fat loss during that same period. Initially, you might not see a change in scale weight, but you'll notice that you're getting leaner and more muscular. We've observed this weight homeostasis effect when doing Dexa scans on subjects.*
- Bigger Muscle Pumps:* Within a few days, muscle pumps should come much more quickly and easily, and be noticeably larger (even to others in the gym). The pump should also last longer after the workout is completed. Even at rest, the muscles of Indigo-3G users can feel and appear fuller and semi-pumped, especially when taking in ample amounts of quality nutrients.*
- Faster Strength Gains:* Strength increases should come faster and more often. In fact, some reported having to recheck the plates on the bar after a set, thinking they forgot to add weight between sets.*
- Enhanced Work Capacity and Recovery:* Due to enhanced glucose management, almost all users notice what many describe as "limitless energy to do more in the gym." And they also report improved recovery rates.*
Cyanidin-3-O-β-glucoside regulates fatty acid metabolism via an AMP-activated protein kinase-dependent signaling pathway in human HepG2 cells.
Lipids Health Dis. 2012 Jan 13;11:10. doi: 10.1186/1476-511X-11-10. Guo H1, Liu G, Zhong R, Wang Y, Wang D, Xia M.
BACKGROUND: Hepatic metabolic derangements are key components in the development of fatty liver disease. AMP-activated protein kinase (AMPK) plays a central role in controlling hepatic lipid metabolism through modulating the downstream acetyl CoA carboxylase (ACC) and carnitine palmitoyl transferase 1 (CPT-1) pathway. In this study, cyanidin-3-O-β-glucoside (Cy-3-g), a typical anthocyanin pigment was used to examine its effects on AMPK activation and fatty acid metabolism in human HepG2 hepatocytes.
RESULTS: Anthocyanin Cy-3-g increased cellular AMPK activity in a calmodulin kinase kinase dependent manner. Furthermore, Cy-3-g substantially induced AMPK downstream target ACC phosphorylation and inactivation, and then decreased malonyl CoA contents, leading to stimulation of CPT-1 expression and significant increase of fatty acid oxidation in HepG2 cells. These effects of Cy-3-g are largely abolished by pharmacological and genetic inhibition of AMPK.
CONCLUSION: This study demonstrates that Cy-3-g regulates hepatic lipid homeostasis via an AMPK-dependent signaling pathway. Targeting AMPK activation by anthocyanin may represent a promising approach for the prevention and treatment of obesity-related nonalcoholic fatty liver disease.
Cyanidin-3-O-β-glucoside improves obesity and triglyceride metabolism in KK-Ay mice by regulating lipoprotein lipase activity.
J Sci Food Agric. 2011 Apr;91(6):1006-13. doi: 10.1002/jsfa.4275. Epub 2011 Feb 24. Wei X1, Wang D, Yang Y, Xia M, Li D, Li G, Zhu Y, Xiao Y, Ling W.
BACKGROUND: Cyanidin-3-O-β-glucoside (Cy-3-g)-rich foods have been reported to inhibit the onset of obesity, but whether the pure anthocyanin supplementation affects obesity remains uncertain.
RESULTS: Cy-3-g supplementation significantly reduced obesity, accumulation of fat in visceral adipose and liver tissues, and plasma triglyceride levels. Furthermore, adenosine monophosphate (AMP)-activated protein kinase phosphorylation (pAMPK) in the skeletal muscle and visceral adipose were significantly increased by Cy-3-g consumption. This was followed by the activation of lipoprotein lipase (LPL) in plasma and skeletal muscle but the suppression of this enzyme in visceral adipose. LPL activation in skeletal muscle cells and its suppression in adipocytes by Cy-3-g were blocked by inhibition of pAMPK.
CONCLUSION: Our present data thus demonstrate that Cy-3-g improves obesity and triglyceride metabolism in KK-Ay mice. The underlying mechanism is found to be partly related to the activation of LPL in plasma and skeletal muscle, and inhibition of LPL in adipose tissue following the activation of pAMPK.
Cyanidin 3-glucoside attenuates obesity-associated insulin resistance and hepatic steatosis in high-fat diet-fed and db/db mice via the transcription factor FoxO1.

Obesity is a major risk factor for the development of type 2 diabetes, and both conditions are now recognized to possess significant inflammatory components underlying their pathophysiologies. Here, we hypothesized that cyanidin 3-glucoside (C3G), a typical anthocyanin reported to possess potent anti-inflammatory properties, would ameliorate obesity-associated inflammation and metabolic disorders, such as insulin resistance and hepatic steatosis in mouse models of diabesity. Male C57BL/6J obese mice fed a high-fat diet for 12 weeks and genetically diabetic db/db mice at an age of 6 weeks received dietary C3G supplementation (0.2%) for 5 weeks. We found that dietary C3G lowered fasting glucose levels and markedly improved the insulin sensitivity in both high-fat diet fed and db/db mice as compared with unsupplemented controls. White adipose tissue messenger RNA levels and serum concentrations of inflammatory cytokines (tumor necrosis factor-α, interleukin-6, and monocyte chemoattractant protein-1) were reduced by C3G, as did macrophage infiltration in adipose tissue. Concomitantly, hepatic triglyceride content and steatosis were alleviated by C3G. Moreover, C3G treatment decreased c-Jun N-terminal kinase activation and promoted phosphorylation and nuclear exclusion of forkhead box O1 after refeeding. These findings clearly indicate that C3G has significant potency in antidiabetic effects by modulating the c-Jun N-terminal kinase/forkhead box O1 signaling pathway and the related inflammatory adipocytokines.
Cyanidin 3-glucoside ameliorates hyperglycemia and insulin sensitivity due to downregulation of retinol binding protein 4 expression in diabetic mice.
Biochem Pharmacol. 2007 Dec 3;74(11):1619-27. Epub 2007 Aug 10.
Adipocyte dysfunction is strongly associated with the development of obesity and insulin resistance. It is accepted that the regulation of adipocytokine expression is one of the most important targets for the prevention of obesity and improvement of insulin sensitivity. In this study, we have demonstrated that anthocyanin (cyanidin 3-glucoside; C3G) which is a pigment widespread in the plant kingdom, ameliorates hyperglycemia and insulin sensitivity due to the reduction of retinol binding protein 4 (RBP4) expression in type 2 diabetic mice. KK-A(y) mice were fed control or control +0.2% of a C3G diet for 5 weeks. Dietary C3G significantly reduced blood glucose concentration and enhanced insulin sensitivity. The adiponectin and its receptors expression were not responsible for this amelioration. C3G significantly upregulated the glucose transporter 4 (Glut4) and downregulated RBP4 in the white adipose tissue, which is accompanied by downregulation of the inflammatory adipocytokines (monocyte chemoattractant protein-1 and tumor necrosis factor-alpha) in the white adipose tissue of the C3G group. These findings indicate that C3G has significant potency in an anti-diabetic effect through the regulation of Glut4-RBP4 system and the related inflammatory adipocytokines.
Anthocyanin enhances adipocytokine secretion and adipocyte-specific gene expression in isolated rat adipocytes.
Biochem Biophys Res Commun. 2004 Mar 26;316(1):149-57.
Adipocyte dysfunction is strongly associated with the development of obesity and insulin resistance. It is accepted that the regulation of adipocytokine secretion or the adipocyte-specific gene expression is one of the most important targets for the prevention of obesity and amelioration of insulin sensitivity. In this study, we demonstrated that anthocyanins (cyanidin or cyanidin 3-glucoside) have the potency of a unique pharmacological function in isolated rat adipocytes. Treated adipocytes with anthocyanins enhanced adipocytokine (adiponectin and leptin) secretion and up-regulated the adipocyte specific gene expression without activation of PPARgamma in isolated rat adipocytes. The gene expression of adiponectin was also up-regulated in white adipose tissue in mice fed an anthocyanin supplemented diet. As one of the possible mechanisms, AMP-activated protein kinase activation would be associated with these changes, nevertheless, the AMP:ATP ratio was significantly decreased by administration of the anthocyanins. These data suggest that anthocyanins have a potency of unique therapeutic advantage and also have important implications for preventing obesity and diabetes.
Cyanidin 3-glucoside protects 3T3-L1 adipocytes against H2O2- or TNF-alpha-induced insulin resistance by inhibiting c-Jun NH2-terminal kinase activation.
Biochem Pharmacol. 2008 Mar 15;75(6):1393-401. Epub 2007 Dec 3.
Anthocyanins are naturally occurring plant pigments and exhibit an array of pharmacological properties. Our previous study showed that black rice pigment extract rich in anthocyanin prevents and ameliorates high-fructose-induced insulin resistance in rats. In present study, cyanidin 3-glucoside (Cy-3-G), a typical anthocyanin most abundant in black rice was used to examine its protective effect on insulin sensitivity in 3T3-L1 adipocytes exposed to H(2)O(2) (generated by adding glucose oxidase to the medium) or tumor necrosis factor alpha (TNF-alpha). Twelve-hour exposure of 3T3-L1 adipocytes to H(2)O(2) or TNF-alpha resulted in the increase of c-Jun NH(2)-terminal kinase (JNK) activation and insulin receptor substrate 1 (IRS1) serine 307 phosphorylation, concomitantly with the decrease in insulin-stimulated IRS1 tyrosine phosphorylation and cellular glucose uptake. Blocking JNK expression using RNA interference efficiently prevented the H(2)O(2)- or TNF-alpha-induced defects in insulin action. Pretreatment of cells with Cy-3-G reduced the intracellular production of reactive oxygen species, the activation of JNK, and attenuated H(2)O(2)- or TNF-alpha-induced insulin resistance in a dose-dependent manner. In parallel, N-acetyl-cysteine, an antioxidant compound, did not exhibit an attenuation of TNF-alpha-induced insulin resistance. Taken together, these results indicated that Cy-3-G exerts a protective role against H(2)O(2)- or TNF-alpha-induced insulin resistance in 3T3-L1 adipocytes by inhibiting the JNK signal pathway.

Adipocyte dysfunction is strongly associated with the development of obesity and insulin resistance. It is accepted that the regulation of adipocytokine secretion or the adipocyte specific gene expression is one of the most important targets for the prevention of obesity and amelioration of insulin sensitivity. Recently, we demonstrated that anthocyanins, which are pigments widespread in the plant kingdom, have the potency of anti-obesity in mice and the enhancement adipocytokine secretion and its gene expression in adipocytes. In this study, we have shown the gene expression profile in human adipocytes treated with anthocyanins (cyanidin 3-glucoside; C3G or cyanidin; Cy). The human adipocytes were treated with 100 microM C3G, Cy or vehicle for 24 h. The total RNA from the adipocytes was isolated and carried out GeneChip microarray analysis. Based on the gene expression profile, we demonstrated the significant changes of adipocytokine expression (up-regulation of adiponectin and down-regulation of plasminogen activator inhibitor-1 and interleukin-6). Some of lipid metabolism related genes (uncoupling protein2, acylCoA oxidase1 and perilipin) also significantly induced in both common the C3G or Cy treatment groups. These studies have provided an overview of the gene expression profiles in human adipocytes treated with anthocyanins and demonstrated that anthocyanins can regulate adipocytokine gene expression to ameliorate adipocyte function related with obesity and diabetes that merit further investigation.

Recently, we demonstrated that anthocyanins, which are pigments widespread in the plant kingdom, have the potency of anti-obesity in mice and the enhancement adipocytokine secretion and adipocyte gene expression in adipocytes. In this study, we have shown for the first time the gene expression profile in isolated rat adipocytes treated with anthocyanins (cyanidin 3-glucoside; C3G or cyanidin; Cy). The rat adipocytes were treated with 100 muM C3G, Cy or vehicle for 24 h. The total RNA from the adipocytes was isolated and carried out GeneChip microarray analysis. A total of 633 or 427 genes was up-regulated (>1.5-fold) by the treatment of adipocytes with C3G or Cy, respectively. The up-regulated genes include lipid metabolism and signal transduction-related genes, however, the altered genes were partly different between the C3G- and Cy-treated groups. Based on the gene expression profile, we demonstrated the up-regulation of hormone sensitive lipase and enhancement of the lipolytic activity by the treatment of adipocytes with C3G or Cy. These data have provided an overview of the gene expression profiles in adipocytes treated with anthocyanins and identified new responsive genes with potentially important functions in adipocytes related with obesity and diabetes that merit further investigation.
Hypoglycemic activity of a novel anthocyanin-rich formulation from lowbush blueberry, Vaccinium angustifolium Aiton.
Phytomedicine. 2009 May;16(5):406-15. Epub 2009 Mar 20.
Blueberry fruits are known as a rich source of anthocyanin components. In this study we demonstrate that anthocyanins from blueberry have the potency to alleviate symptoms of hyperglycemia in diabetic C57b1/6J mice. The anti-diabetic activity of different anthocyanin-related extracts was evaluated using the pharmaceutically acceptable self-microemulsifying drug delivery system: Labrasol. Treatment by gavage (500 mg/kg body wt) with a phenolic-rich extract and an anthocyanin-enriched fraction formulated with Labrasol lowered elevated blood glucose levels by 33 and 51%, respectively. The hypoglycemic activities of these formulae were comparable to that of the known anti-diabetic drug metformin (27% at 300 mg/kg). The extracts were not significantly hypoglycemic when administered without Labrasol, demonstrating its bio-enhancing effect, most likely due to increasing the bioavailability of the administered preparations. The phenolic-rich extract contained 287.0+/-9.7 mg/g anthocyanins, while the anthocyanin-enriched fraction contained 595+/-20.0 mg/g (cyanidin-3-glucoside equivalents), as measured by HPLC and pH differential analysis methods. The greater hypoglycemic activity of the anthocyanin-enriched fraction compared to the initial phenolic-rich extract suggested that the activity was due to the anthocyanin components. Treatment by gavage (300 mg/kg) with the pure anthocyanins, delphinidin-3-O-glucoside and malvidin-3-O-glucoside, formulated with Labrasol, showed that malvidin-3-O-glucoside was significantly hypoglycemic while delphinidin-3-O-glucoside was not.
Dietary cyanidin 3-O-beta-D-glucoside-rich purple corn color prevents obesity and ameliorates hyperglycemia in mice.
J Nutr. 2003 Jul;133(7):2125-30.
Anthocyanins, which are used as a food coloring, are widely distributed in human diets, suggesting that we ingest large amounts of anthocyanins from plant-based foods. Mice were fed control, cyanidin 3-glucoside-rich purple corn color (PCC), high fat (HF) or HF + PCC diet for 12 wk. Dietary PCC significantly suppressed the HF diet-induced increase in body weight gain, and white and brown adipose tissue weights. Feeding the HF diet markedly induced hypertrophy of the adipocytes in the epididymal white adipose tissue compared with the control group. In contrast, the induction did not occur in the HF + PCC group. The HF diet induced hyperglycemia, hyperinsulinemia and hyperleptinemia. These perturbations were completely normalized in rats fed HF + PCC. An increase in the tumor necrosis factor (TNF)-alpha mRNA level occurred in the HF group and was normalized by dietary PCC. These results suggest that dietary PCC may ameliorate HF diet-induced insulin resistance in mice. PCC suppressed the mRNA levels of enzymes involved in fatty acid and triacylglycerol synthesis and lowered the sterol regulatory element binding protein-1 mRNA level in white adipose tissue. These down-regulations may contribute to triacylglycerol accumulation in white adipose tissue. Our findings provide a biochemical and nutritional basis for the use of PCC or anthocyanins as a functional food factor that may have benefits for the prevention of obesity and diabetes.
