Final answer:
If a person consumes 3000 calories per day and only needs 2000 calories, they are likely to gain weight rather than lose weight.
Step-by-step explanation:
On average, a person needs 1500 to 2000 calories per day to sustain daily activities. If a person regularly consumes 3000 calories per day, they are consuming more energy than they need. According to the calories in equal calories out equation, if a person uses more energy than they consume, their body will obtain the needed energy by metabolizing body fat. Therefore, if a person consumes 3000 calories per day and only needs 2000 calories, they are likely to gain weight rather than lose weight.
