In which condition will a diet be considered energy-dense but nutritionally weak?

Correct answer: When oil and sugar are high but fibre and micronutrients are low

An energy-dense diet supplies many calories in a relatively small amount, often because it contains substantial oil, sugar, or refined ingredients. It becomes nutritionally weak when it lacks fibre, protein quality, vitamins, minerals, and protective foods such as vegetables, fruits, pulses, or whole grains. Thus, high energy content alone does not mean a balanced diet.
