Intramyocellular triglyceride (imTG) in skeletal muscle plays a significant role in metabolic health, and an infusion of [13C16]palmitate can be used to quantitate the in vivo fractional synthesis rate (FSR) and absolute synthesis rate (ASR) ...
- Intramuscular triacylglycerol in energy metabolism during exercise in humans - PubMed
Intramuscular triacylglycerol (IMTG) represents an energy store that can be used during exercise, when it may contribute up to 20% of total energy turnover depending on diet, gender, and exercise type.

Thus, removal of Pparγ has no impact on glucose homeostasis. Next, we evaluated whether mFATBLOCK mice display any defects in their lipid homeostasis (Figure 1D). We failed to detect any significant differences in their serum levels of triglycerides (TG), total cholesterol (TC), or free fatty acids (FFA, Figure 1D).

The fat that's stored just beneath your skin — the kind that you can pinch between your fingers — is called subcutaneous fat and is generally considered less harmful that visceral fat, the fat behind your abdominal muscles that can't be seen.
- Fitness Myths: Separating Fact from Fiction
Spot reduction is one of the most pervasive fitness myths. Doing hundreds of crunches won’t burn belly fat. Fat loss happens across the entire body and is largely influenced by genetics, nutrition, and overall activity level. Instead of trying to “tone” a specific area, focus on full-body strength training and cardiovascular activity, paired with a balanced diet. For the average adult, lifting weights will result in a gain of muscle mass.
