What should a client aim to consume for weight increase or size and strength increase?

For a client aiming to increase weight, size, and strength, it is important to focus on a caloric surplus, which means consuming more calories than the body burns. The correct approach involves calculating the Basal Metabolic Rate (BMR) — the number of calories the body needs at rest to maintain basic physiological functions — and then factoring in the total energy expenditure which includes physical activity and digestion.

By adding a surplus of approximately 500 calories to the sum of BMR and total daily expenditures, the client can create a caloric intake that is high enough to promote weight gain. This surplus accounts for not just maintaining current weight but providing the additional energy necessary for muscle growth and recovery from workouts.

Achieving muscle gain typically requires sufficient nutritional support, including protein and calorie surplus, to stimulate hypertrophy. Therefore, consuming BMR plus total expenditures plus an additional 500 calories is the most logical strategy for someone looking to gain weight and improve strength effectively, supporting their fitness goals in a sustainable manner.
