The loss of sea ice is dramatically reducing the number of seals with their high fat content, consumed by polar bears. A recent study found that other foods have too little fat and require too much effort for the bears to find. They are losing weight badly.
For threatened polar bears, the climate change diet is a losing proposition
With Arctic sea ice shrinking from climate change, many polar bears have to shift their diets to land during parts of the summer.

Polar bear energetic and behavioral strategies on land with implications for surviving the ice-free period - Nature Communications
Declining Arctic sea ice is increasing polar bear land use. Here, the authors follow 20 different polar bears on land over 3 years and measure daily energy expenditure finding that despite behavioural and diet plasticity the bears are at risk of starvation.
