Consequences of Crash Dieting Water Loss

The provided passage discusses the negative effects of crash dieting, particularly focusing on the rapid loss of water from the body. It explains that this water loss is often mistaken for fat loss but actually leads to several detrimental health consequences.

Analyzing Dieting Consequences

Let's examine the effects mentioned in the passage concerning water loss from crash dieting:

• Impaired Health Functions: The passage explicitly states that losing body water "impairs circulation, reduces muscle bone, joint and bone health and obviously overworks the kidney, heart and lungs."
• Body Odour: It also notes that water loss "will also lead to body odour because the composition of sweat changes."
• Temporary Weight Loss: Bodybuilders use this method to quickly reduce weight for competition, fitting into lower weight classes, but this is temporary and unhealthy.

Evaluating the Options

Based on the passage, we can evaluate each option provided:

• Option 1: improved muscle bone - The passage clearly states that water loss *reduces* muscle and bone health, making this option incorrect.
• Option 2: better joint and bone health - Similar to option 1, the text indicates that water loss negatively impacts joint and bone health, contradicting this statement.
• Option 3: overworked kidney, heart and lungs - The passage directly mentions that crash dieting leading to water loss "obviously overworks the kidney, heart and lungs." This aligns perfectly with the text.
• Option 4: decreased body odour - The passage states the opposite: water loss leads to body odour due to changes in sweat composition. Therefore, this option is incorrect.

Conclusion: The most direct and accurate consequence of water loss due to crash dieting, as stated in the passage, is the strain placed on vital organs.
