As early as 1969, research showed that losing just 3 percent of your body weight resulted in a 17 percent slowdown in your metabolism—a body-wide starvation response that blasts you with hunger hormones and drops your internal temperature until you rise back to your highest weight.
On average, the starvation response of the individuals after isolation was a 750-kilojoule (180-kilocalorie) reduction in daily total energy expenditure. 250 kJ (60 kcal) of the starvation response was explained by a reduction in fat-free mass and fat mass. An additional 270 kJ (65 kcal) was explained by a reduction in fidgeting. The remaining ...
They revealed that exercise appeared to cause biological and structural changes in belly fat, also called adipose tissue, that lowered a person’s risk for heart disease and metabolic disorders ...
However, its accuracy declines at the extremes of body fat percentages, tending to slightly understate the percent body fat in overweight and obese persons (by 1.68–2.94% depending on the method of calculation), and to overstate to a much larger degree the percent body fat in very lean subjects (by an average of 6.8%, with up to a 13% ...

[37] [38] Similarly, heavy consumption of fried food is linked to greater obesity risk on a population level. [39] On a more individual level, the relative risk of fried food consumption and increased weight gain seems to depend on genetic ...
