Final answer:
The notion that set-point body weight is solely dictated by genetics and merely revealed through environmental influences is false; body weight is influenced by a complex interaction of genetics and environmental factors.
Step-by-step explanation:
The statement that set-point body weight is predetermined by our genes, but is commonly unmasked by the environment is considered false. While it's true that genetics play a role in determining an individual's body weight, the set-point theory, which suggests the existence of an ideal weight determined by genetics, is overly simplistic. This theory fails to fully account for the dynamics of energy balance and does not explain the impact of environmental and social factors on body weight regulation. Research has shown that there is no significant change in metabolic rate between individuals who have recently lost weight and those who have not, challenging the concept that the body defends a specific set-point. Furthermore, factors such as social status, physical activity levels, and food availability play a substantial role in determining body weight, indicating a complex interplay between genetics and the environment.
