Human
In general, humans can survive for two to eight weeks without food, depending on stored body fat. Survival without water is usually limited to three or four days. About 36 million humans die every year from causes directly or indirectly related to starvation. Childhood malnutrition is also common and contributes to the global burden of disease. However global food distribution is not even, and obesity among some human populations has increased rapidly, leading to health complications and increased mortality in some developed, and a few developing countries. Worldwide over one billion people are obese, while in the United States 35% of people are obese, leading to this being described as an "obesity epidemic." Obesity is caused by consuming more calories than are expended, so excessive weight gain is usually caused by an energy-dense diet.
Alain Bombard
Bombard's claim was later tested and contested by Hannes Lindemann, a German physician, canoeist and sailing pioneer, although both the French and Taiwanese navies concurred with Bombard's findings, the Taiwanese exercise extending to 134 days. Lindemann wanted to repeat Bombard's trip in order to gain a better understanding of living on salt water and fish, but found that he needed fresh water (from rain) most days. Lindemann later claimed that Bombard had actually taken along fresh water and consumed it on the ocean, and that he had also been secretly provided further supplies during his voyage. Lindemann's own observations about reactions to scarce fresh water supplies became the basis for the World Health Organization's navigation recommendations.
