What role does Triglyceride play in weight loss?

Triglycerides are the main form of fat storage in the body and serve as an energy reserve. In weight loss, they play an indirect role: a calorie deficit forces the body to break down stored triglycerides from adipose tissue for energy. High blood triglyceride levels are often linked to obesity, insulin resistance, and metabolic syndrome. Weight reduction typically lowers triglyceride levels significantly. Genetic variants like rs3135506 in the APOA5 gene can influence triglyceride regulation, but the effect is modest. Omega-3 fatty acids can lower triglycerides but do not replace lifestyle changes. Importantly, triglycerides themselves are not a tool for weight loss but a biomarker. A balanced diet and exercise are key. Evidence is based on observational studies; direct causal effects are hard to isolate.
