Question

Quizplus · Accepted Answer

People with a higher percentage of body fat have a lower resting metabolic rate, which means that it takes fewer calories for their bodies to maintain fat tissue than muscle tissue. This can make weight loss more difficult, as they need to consume even fewer calories to create a deficit. Therefore, Isaac will likely have difficulty losing weight while dieting due to his past obesity and lack of physical activity, which may have decreased his muscle mass and increased his percentage of body fat.
