Explanation:

Question 40

To build muscle mass, protein is key, but also, resistance training (which is related to muscle growth) and sufficient calorie intake (including carbohydrates for energy during workouts and recovery) or more precisely, a positive calorie balance with adequate protein and nutrients. However, among the options: "Low carbohydrate intake" is not helpful (carbs are needed for energy). "At least 150 minutes per week of cardiovascular exercise" is for cardio/endurance, not muscle building. "Frequent resistance training exercise" – resistance training (like weightlifting) is crucial for muscle hypertrophy (growth). "Reduced calorie intake" would hinder muscle building as you need energy and nutrients to build muscle. Wait, no – wait, the options: Wait, the question is "Which of the following is needed to build muscle mass?". Let's re-express the options:

• Low carbohydrate intake: Carbs are a primary energy source, especially during workouts. Low carbs would limit energy for intense workouts, so not helpful.
• At least 150 minutes per week of cardiovascular exercise: Cardio is for heart/lung health, endurance, not muscle building (though it can complement, but not the main factor).
• Frequent resistance training exercise: Resistance training (e.g., weightlifting) creates the stimulus for muscle fibers to adapt and grow (hypertrophy). So this is a key component.
• Reduced calorie intake: To build muscle, you generally need a calorie surplus (or at least maintenance with sufficient protein) – reduced calories would make it hard to build muscle as the body needs energy and nutrients to repair and grow muscle tissue.

So the correct option is "Frequent resistance training exercise".

Resistance training (like weightlifting) has several benefits. Let's analyze the options:

• Improves HDL and LDL cholesterol: Resistance training can improve lipid profiles – increasing HDL (good cholesterol) and decreasing LDL (bad cholesterol) or improving the ratio. This is a known benefit.
• Assists with digestion: Resistance training isn't a primary digestive aid (though overall fitness can help digestion, but this is not a direct/primary benefit).
• Decreases the risk of diarrhea and constipation: Not a direct benefit of resistance training.
• Increases absorption of vitamins: Resistance training doesn't directly impact vitamin absorption.

So the benefit of resistance training is improving HDL and LDL cholesterol.

Mindful eating involves being present during eating, paying attention to hunger/fullness cues, savoring food, etc. For weight loss:

• Mindful eating helps you recognize when you're full, so you eat less (reduced calorie intake), avoid emotional eating, make better food choices. It increases awareness of portion sizes, hunger signals, so it assists with weight loss by promoting intentional eating, reducing overeating, and helping you stick to a calorie deficit (if that's your goal) in a more sustainable way.

Answer:

Frequent resistance training exercise (the option with "Frequent resistance training exercise")
