Fish Oil And Weight Control
New research has found that fish oil can transform fat-storage cells into fat-burning cells, which may help reduce weight gain in middle age.
According to the study in Nature Scientific Reports, fish oil activates receptors in the digestive tract, and triggers activity in the sympathetic nervous system that induces specific type of fat cells to metabolise fat.
Fat tissues don’t all store fat. So-called “white” cells store fat in order to maintain energy supply, while “brown” cells metabolise fat to maintain a stable body temperature. Brown cells are abundant in babies but decrease in number with maturity into adulthood.
Normally, humans have three types of fat cells, white, brown and the newly discovered beige cells. Brown and beige cells metabolise fat for temperature control while white cells store fat for energy. The number of brown and beige cells decline as we get older.
However, Japanese researchers have found that consuming more fish oil can help turn white storage cells into beige metabolising cells and contribute to weight loss.
A third type of fat cell – “beige” cells – have recently been discovered in humans and mice, and have shown to function much like brown cells. Beige cells also reduce in number as people approach middle age; without these metabolising cells, fat continues accumulating for decades without ever being used.
The scientists investigated whether the number of these beige cells could be increased by increasing intake of fish oils.
“We knew from previous research that fish oil has tremendous health benefits, including the prevention of fat accumulation,” says senior author Teruo Kawada. “We tested whether fish oil and an increase in beige cells could be related.”
The team fed one group of mice fatty food, and four other groups received fatty food with four different types of fish oil enriched with either low or high dose DHA (docosahexaenoic acid) or low or high dose EPA (eicosapentaenoic acid). Whatever type of fish oil they were supplemented with, the mice in those groups gained 5-10 percent less weight and 15-25 percent less fat compared to those that did not consume any oil.
Both the DHA and EPA rich oils produced similar results and the scientists speculate that if combined they could have a more potent synergistic effect.
The study also found that beige cells formed from white fat cells when the sympathetic nervous system was activated, meaning that certain fat-storage cells can shift from storage cells to metabolising cells.
Although this was an animal study, it points the way towards our understanding of how different aspects of diet can help or hinder health.
“People have long said that food from Japan and the Mediterranean contribute to longevity, but why these cuisines are beneficial was up for debate,” says Kawada. “Now we have better insight into why that may be.”

Renaissance Energy Pledges Stronger Partnership With RIVCHPP
Renaissance Africa Energy Limited has pledged to strengthen its partnership with the Rivers State Contributory Health Protection Programme (RIVCHPP), following an advocacy visit by the agency’s management to the company’s headquarters in Port Harcourt.
The company’s General Manager, Health, Dr. Akinwumi Fajola, said the proposed partnership would involve the constitution of a joint team comprising representatives of Renaissance and RIVCHPP to deliberate on and develop modalities for deeper collaboration.
Fajola, who spoke during the visit, said the engagement would help strengthen the agency’s operations and advance the attainment of Universal Health Coverage in Rivers State.
He noted that the seeming bottlenecks often associated with government agencies had made some organisations and individuals sceptical about engaging with them.
According to him, the leadership style of the RIVCHPP Executive Secretary had demonstrated positive changes capable of attracting public and private-sector partners.
He stated that Renaissance Energy Limited would further strengthen its engagement with RIVCHPP, particularly in promoting health insurance within its operational areas.
Earlier, Agala described RIVCHPP as a legacy project of the State Governor, Siminalayi Fubara, established to ensure that Rivers residents have access to quality and affordable healthcare in line with the administration’s #Health4AllRivers vision.
She said since the agency became operational in January 2024, it had sustained awareness campaigns across the formal and informal sectors, resulting in steady growth in enrolment.
Agala disclosed that RIVCHPP had enrolled more than 160,000 residents across the state’s 23 Local Government Areas, giving them access to healthcare services.
She also said although Rivers was among the last states in the country to operationalise a health insurance agency, it had risen to 13th position in Universal Health Coverage and was recognised as the most improved state at the Federal Ministry of Health’s 2025 joint annual review meeting.
The Executive Secretary said the agency was implementing comprehensive healthcare plans covering all population groups, including vulnerable residents, to protect households from health poverty and catastrophic health expenditure.
She commended Renaissance Energy Limited for promoting health insurance in its operational areas and congratulated Fajola on his recent promotion.
The visit featured the exchange of promotional materials and souvenirs between the two organisations.
