Reducing added sugars and fats can quickly improve how people feel, which is the explanation Beth Czerwony gives in the New York Times piece.

1. Relevant knowledge points and concepts
- Blood sugar regulation: High intake of added sugars and refined carbs causes rapid glucose spikes followed by crashes, producing fatigue and brain fog.
- Energy density and inflammation: Diets high in added fats and processed foods can promote sluggishness and low-grade inflammation, reducing perceived energy.
- Behavioral change on a “cleanse”: Many cleanses inadvertently remove processed snacks and sugary beverages, improving overall dietary quality and short-term energy.

2. Step-by-step reasoning
- Step 1: A person begins a cleanse and typically removes processed foods, sugary drinks, and high-fat convenience items.
- Step 2: Removing added sugars reduces repeated glucose spikes and subsequent crashes.
- Step 3: Lower intake of these energy-destabilizing foods leads to more stable blood sugar and fewer post-meal energy dips.
- Step 4: The individual therefore perceives increased energy and alertness, at least in the short term.

3. Calculations (none required)
- No numerical calculation is necessary; the explanation is physiological and behavioral.

4. Why the correct answer is correct
- “They consume fewer added sugars and fats” directly captures the mechanism Czerwony describes: the perceived energy boost often comes not from a mysterious detoxification, but from cutting out foods that cause blood sugar volatility and sluggishness. This results in improved energy and cognitive clarity.

5. Why the other options are incorrect
- “They consume more refined carbohydrates.” Refined carbs (like white bread, pastries) typically worsen blood sugar swings and lead to more fatigue, not more energy.
- “They have higher levels of oxalate in their system.” Oxalate relates to kidney stone risk, not short-term energy levels; it’s unrelated to feeling more energetic on a cleanse.
- “They eliminate vegetables and fruits from their diets.” Removing fruits and vegetables would generally reduce fiber, micronutrients, and sustained energy, and is unlikely to produce increased energy.

6. Conclusion
This reasoning confirms the provided correct answer: They consume fewer added sugars and fats.
