Weight loss in elderly may harm bone strength
New York, June 3 : While losing excess weight can be considered healthy, researchers claim that it may reduce bone density, bone architecture and bone strength in older adults.
According to the study, the magnitude of changes to the skeleton were clinically significant and translated into an almost three-fold increase in the risk of fracture for those who lost five per cent or more weight over 40 years.
Long-term and recent weight loss were found to be associated with lower cortical density and thickness, higher cortical porosity, and lower trabecular density and number in the elderly.
"We showed that men and women with both shorter term weight loss over 4-6 years and longer term weight loss over 40 years had more micro-architectural deterioration of their bones than persons who did not lose weight," said principal investigator Douglas P. Kiel from the Hebrew Seniorlife Institute for Aging Research, US
The study published in the Journal of Bone and Mineral Research, included 769 women, 595 men with an average age of 70.
Weight measurements taken every 4-6 years were used to assess recent weight change over 6 years and long-term change over 40 years.
"Older adults who are losing weight should be aware of the potential negative effects on the skeleton and may want to consider counteracting these effects through interventions such as weight-bearing exercise and eating a balanced diet," said senior author, Elizabeth Samelson.
"Given that weight loss is highly common in older adults, further work is needed to evaluate if these bone deficits can be prevented through interventions or therapy," Samelson noted.

VCK urges CM Vijay to enact stringent law against superstitious practices
Chennai (PTI): VCK MLA Vanni Arasu on Wednesday urged the newly formed Tamil Nadu government to enact a stringent law against superstitious practices, citing similar legislations in Karnataka and Maharashtra to curb exploitation in the name of black magic and rituals.
VCK, which won two seats in the 2026 Assembly election, has offered support to TVK to form a government during the floor test.
Speaking during the discussion on the confidence motion in the Assembly, Arasu highlighted that states like Bihar, Jharkhand, Chhattisgarh, Odisha, and Rajasthan already have laws against witchcraft and sorcery.
"From 2013 in Maharashtra and 2020 in Karnataka, laws providing imprisonment for those who deceive through superstitious means have been in practice," he stated. The party noted that rationalist Narendra Dabholkar had fought for such a law in Maharashtra before being murdered by "Sanatana terrorists".
The VCK MLA further called on the government to prioritise scientific temper over beliefs in astrology and sorcery.
"Our government should give priority to projects that develop science without giving room for superstitions like astrology and black magic," Arasu said, citing Article 51A of the Indian Constitution, which defines the development of scientific temper as a fundamental duty of every citizen.
The party demanded a special law to prevent honour killings as well, which Arasu claimed are rising in Tamil Nadu as they once did in North Indian states.
The government was also urged to enact legislation protecting the "200-point roster system" for SC/ST employee promotions, utilising powers under Article 16(4A) of the Constitution.
Highlighting the recent arrest of 40 Tamil Nadu fishermen by the Sri Lankan Navy, the VCK sought a permanent solution to protect them from such attacks.
The party called on the state government to take initiatives toward the "right of Eelam Tamils to rule themselves" and requested that the state officially observe May 18 as International Genocide Day.
