Step-by-step explanation:

When considering the relationship between calorie intake and weight loss, it is essential to understand that weight management is influenced by the balance between calories consumed and calories expended. A reduction or energy expenditure to lose 1 lb of body weight is generally equated to a deficit of approximately 3,500 kilocalories (kcal).

The concept of energy balance can be summarized as follows: if the amount of calories you consume through food and drink is equal to the calories your body uses up through daily activities and metabolic processes, your weight will remain stable. To lose weight, you must consume fewer calories than your body uses, creating a calorie deficit.
