PPARG Interacts with These Diseases
If you have low PPAR gamma, you should take PPAR gamma activators. The natural compounds listed here are so-called partial agonists of PPARgamma.
The drugs that activate PPARgamma (thiazolidinediones) are considered "full agonists" and have somewhat of a different effect. The partial agonists are weaker, but also have fewer side effects.
Calorie restriction decreases PPAR gamma gene expression, whereas a high-fat diet increased PPARG gene expression in the fat cells of mice. (R) So people with lower PPAR gamma might do better with higher fat content (especially omega-3 & omega-6).
It's possible that people who have low PPARs do worse with a low carb diet because they have low insulin levels and staying away from carbs exacerbates this issue.
Common PPAR Gamma Activators
In general, PPAR gamma apparently prefers polyunsaturated fatty acids such as linoleic acid, arachidonic acid, and EPA (R). Even though PPAR gamma activators can cause obesity, there are other mechanisms by which these supplements work that they either break even or cause weight loss.
- Exercise (R, R2) - in muscle as well,
- Omega 6: Linoleic acid (R), Arachidonic acid and arachidonic acid metabolites (R)
- Omega 3: -linolenic acid (R), ( Flax, chia),
- Fatty acids and prostanoids (R),
- Ketosis (R),
- Cold Exposure (R, R2) - also activates PGC-1a and PPAR-a
- Insulin from carbs (R, R2),
- Glycine found in collagen (R),
- Curcumin found in turmeric (R),
- Cinnamon (R),
- Fish Oil (R),
- CLA found in dairy (R),
- Coconut oil/19% Myristic Acid (R),
- MCT oil/ Capric acid (R),
- EGCG or tea (R),
- Oregano/Biochanin A (R), Oregano oil/Carvacrol (R),
- Soy: Daidzein (R), Genistein (R),
- Sage/Carnosic acid and carnosol (R),
- Vitamin E/Tocotrienols (R),
- Rosemary/Carnosic acid and carnosol (R)
- Naringenin found in grapefruit (R),
- Ginger/6-shogaol (R),
- Ellagic acid found in pomegranate (R),
- Flavanoids found in plants: Quercetin (R), Kaempferol (R), Apigenin (Low EC50)(R), Chrysin (Low EC50) (R), Luteolin (R), Hesperidin (Low EC50) (R),
- Licorice/Glycyrrhizic Acid (R), Licochalcone E (R),
- Goji Berries (R),
- Pistachios/oleanonic acid (R),
To activate PPARs, you need to also activate retinoic acid receptors (RXR). RXR is activated by the vitamin A found in animals (retinol), not plants. Although beta-carotene, which is found in plants, converts to it.
Other PPAR Gamma Activators

Substances That Increase PPARG
Substances That Decrease PPARG
PPAR is a protein that binds to DNA to increase gene expression i.e. to produce other important proteins. There are three types: alpha, beta/delta, and gamma.
PPAR gamma can be activated in various cells, but it's most significant in fat cells/adipose tissue, followed by a colon, then kidney, then liver cells.
PPAR gamma (PPARy) most significantly increases insulin sensitivity and insulin secretion, which decreases blood glucose. (R) PPARs are generally anti-inflammatory and block inflammation (MAPK, NF-kappaB, and others).
PPARy increases FGF-21 . FGF-21 has been shown to benefit insulin sensitivity, blood glucose, cholesterol profile and decrease body weight in obese mice and diabetic monkeys, without increased cancer or other side effects. (R)
Even though PPAR gamma increases FGF-21, which in turn increases energy expenditure, obese people have higher levels of FGF-21 . (R) This is simply because in the modern environment we just eat way too much for the amount of exercise we do.
Through these mechanisms, it's believed that it decreases heart disease. (R) Diseases such as Multiple sclerosis and Alzheimer are associated with lower PPARgamma . (R) PPAR gamma decreases inflammation and can help IBD (Crohn's, colitis). (R)
ApoE is an anti-inflammatory, anti-oxidant and junk removal protein. It also lowers cholesterol. PPAR gamma increases PON1 (R), which is an antioxidant and protects your heart. It's important for handling pesticides.
When mice are bred without PPAR gamma , they don't get fat on a high fat diet. (R) However, PPARs also cause weight loss by increasing energy expenditure and the browning of white fat. My guess is that whether you gain or lose weight will depend on your caloric intake and other factors.
CLA is a popular weight loss supplement and it inhibits PPAR gamma (R). Berberine is also a popular weight loss supplement and it also inhibits PPAR gamma . In cancer cells, PPAR gamma has been shown to be involved in tumor growth. (R)
Activation, in general, could theoretically increase your risk for cancer. However, that's not always the case. Honokiol is a supplement that increases PPARy in fat cells but decreases it in some cancer cells. Also, it reduces weight gain in diabetes and doesn't increase fat cells. (R, R2, R3) So we see substances can modify PPARy differently.
PPARs are not good for bone density. They increase bone destroying cells (osteoclasts) and decrease bone-producing cells (osteoblasts). PPARs increase sodium and fluid retention. On the skin, PPAR gamma increases sebum, which leads to acne. (R)
Indicators of low PPARs:
- You are thin and never tried to be thin,
- Have issues with Th1 dominance (PPARy blocks IFNy),
- Have high inflammation. Cytokines like TNF and IL-1 decrease PPARy and PPARy also decreases inflammation. (R) Check your inflammation: Th1/Th2/Th17 dominance.
- Have low fasting insulin (mine was below 2) (PPARs increase insulin),
- You have an HBA1C that's not low even though you eat REALLY healthy (no sugar). PPARs lower blood glucose.
- Low Adiponectin (PPAR gamma increases adiponectin) (R)
- High TGFb (R) (PPARy lowers TGF).
- High IGF-1 (R)
Indicators of normal PPARs:
- You are capable of gaining weight ,
- You're hungry often,
- Don't have chronic inflammation,
- You have high fasting insulin ,
- You're Th2 dominant. PPARy shifts you to a Th2 profile.

Facial adipose tissue may be increased, decreased or normal. Affected individuals show an increased preponderance of insulin resistance, diabetes mellitus and dyslipidemia. [MIM:604367] Defects in PPARG can lead to type 2 insulin-resistant diabetes and hyptertension. PPARG mutations may be associated with colon cancer.
From NCBI Gene: This gene encodes a member of the peroxisome proliferator-activated receptor (PPAR) subfamily of nuclear receptors. PPARs form heterodimers with retinoid X receptors (RXRs) and these heterodimers regulate transcription of various genes. Three subtypes of PPARs are known: PPAR-alpha, PPAR-delta, and PPAR-gamma . The protein encoded by this gene is PPAR-gamma and is a regulator of adipocyte differentiation. Additionally, PPAR-gamma has been implicated in the pathology of numerous diseases including obesity, diabetes, atherosclerosis and cancer. Alternatively spliced transcript variants that encode different isoforms have been described. [provided by RefSeq, Jul 2008] From UniProt: Nuclear receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Once activated by a ligand, the nuclear receptor binds to DNA specific PPAR response elements (PPRE) and modulates the transcription of its target genes, such as acyl-CoA oxidase. It therefore controls the peroxisomal beta-oxidation pathway of fatty acids. Key regulator of adipocyte differentiation and glucose homeostasis. ARF6 acts as a key regulator of the tissue-specific adipocyte P2 (aP2) enhancer. Acts as a critical regulator of gut homeostasis by suppressing NF-kappa-B-mediated proinflammatory responses. Plays a role in the regulation of cardiovascular circadian rhythms by regulating the transcription of ARNTL/BMAL1 in the blood vessels.
