Summary
High trans-fatty acids (TFA) in adipose tissue may link to weight gain. Omega-3 long-chain polyunsaturated fatty acids (LC-PUFA) patterns were not linked to weight loss, with effects depending on the overall fatty acid profile.
Area of Science:
- Nutritional Science
- Human Physiology
- Biochemistry
Background:
- Dietary intake of n-3 long-chain polyunsaturated fatty acids (LC-PUFA) and low n-6 LC-PUFA and 18:1 trans-fatty acids (TFA) may reduce obesity risk.
- Previous research often examined individual fatty acids rather than their combined patterns.
- This study investigates the relationship between overall adipose tissue fatty acid profiles and anthropometric changes.
Purpose of the Study:
- To explore associations between global patterns of adipose tissue fatty acids and changes in body weight and waist circumference.
- To determine if specific fatty acid patterns are predictive of weight gain or loss.
- To understand the role of different fatty acid types (n-3 LC-PUFA, n-6 LC-PUFA, TFA) in anthropometric changes.
Main Methods:
- Analysis of 34 fatty acid species from adipose tissue biopsies in 1100 Danish adults.
- Utilized sex-specific principal component analysis to identify fatty acid patterns.
- Employed multiple linear regression to assess associations with changes in weight and waist circumference, adjusting for confounders.
Main Results:
- Seven principal components explained over 77% of fatty acid variation in both sexes.
- Patterns high in TFA were positively associated with increases in weight and waist circumference in men and women.
- Patterns high in n-6 LC-PUFA showed sex-specific associations: negative in men, positive in women.
- Associations with n-3 LC-PUFA patterns were context-dependent, influenced by other fatty acids present.
Conclusions:
- Adipose tissue fatty acid patterns rich in TFA may contribute to weight gain.
- No clear association was found between n-3 LC-PUFA-rich patterns and weight loss.
- The impact of fatty acid patterns on anthropometry is complex and depends on the overall fatty acid composition.

Obesity
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
Fats as Energy Storage Molecules
Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl-CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis directly...
Hypodermis
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...
