标题: 一道AA作文

The following appeared in the health section of a magazine on trends and lifestles.

"People who use the artificial sweetener aspartame are better off consuming sugar, since aspartame can actually contribute to weight gain rather than weight loss. For example, high levels of aspartame have been shown to trigger a craving for food by depleting the brain of a chemical that registers satiety, or the sense of being full. Furthermore, studies suggest that sugars, if consumed after at least 45 minutes of continuous exercise, actually enhance the body's ability to burn fat. Consequently, those who drink aspartame-sweetened juices after exercise will also lost this calorie-burning benefit. Thus it appears that people consuming aspartame rather than sugar are unlikely to achieve their dietary goals.

能不能请高手翻译一下这篇文章？多谢了

吃人工糖aspartame的人比吃糖的better off （？）。因为aspartame确实可导致增重而不是减重。比如，高浓度的aspartame可通过消耗让大脑产生饱的感觉的化学物质来触发对食物的渴求。进一步地，研究显示，如果在连续运动至少45分钟后消耗糖，可提高身体燃烧脂肪的能力。因此，在运动后喝aspartame做甜味剂的果汁的人将失去消耗calorie的效果。因此食用aspartame的人比吃糖的人更不容易达到他们的饮食（节食？dietary）规定。

非常感谢。不过，这道作文题的逻辑错误在哪？我还是不太明白这篇文章是说aspartame可以导致增重但是为什么又可以推导出“因此，在运动后喝aspartame做甜味剂的果汁的人将失去消耗calorie的效果。”的结论。多谢了。
