强调句中的that可以省略吗

2 强调句中的that可以省略吗

According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions, it’s the beanpoles with big appetites you really need to avoid.

有本资料上解释说，it’s the beanpoles with big appetites you really need to avoid是一个强调句，在you前面省略了that。是这样吗？
