According to Tufts University researchers, by what percentage does our metabolic rate decrease each year from the age of twenty?

The correct answer indicates that our metabolic rate decreases by approximately 2% each year from the age of twenty, according to research from Tufts University. This finding is significant as it highlights a gradual decline in metabolic efficiency as we age. Metabolism is the process through which our body converts food into energy, and as the years progress, various physiological changes occur, such as a reduction in muscle mass and changes in hormonal levels, which contribute to this decline.

Understanding this 2% annual decrease is crucial for those working in nutrition and fitness, as it can inform dietary and exercise recommendations for individuals as they age. Many may not realize the extent of metabolic changes over time, which can impact weight management and overall health strategies. This information emphasizes the importance of maintaining an active lifestyle and balanced nutrition to help counteract these effects and support metabolism throughout adulthood.
