A client's basal metabolic rate is 2,200, their caloric expenditure is 600, and they are consuming 2,200 calories daily. What is the physiological response?

When a client's basal metabolic rate (BMR) is 2,200 calories per day and their caloric expenditure is 600 calories, it indicates how many calories they burn at rest and during activities, respectively. Consuming 2,200 calories daily means that the total calories ingested equal their BMR.

In this scenario, the client is burning a total of 2,800 calories per day when combining the BMR with the caloric expenditure from activities. However, since their dietary intake matches only the BMR at 2,200 calories, they are maintaining their weight because they are not in a caloric surplus or deficit.

Weight maintenance occurs when caloric intake equals caloric expenditure over time. In this case, the client is consuming enough calories to support their BMR, meaning they are maintaining energy balance. Thus, they will not experience weight loss or gain as long as their dietary habits remain consistent with their metabolic needs and energy expenditure. This physiological equilibrium is crucial for understanding how diet and activity influence body weight.
