The doctor () me to eat less meat and take more exercise.

advise与suggest 都可作“建议”讲,二者用法有同有异.
(1) 相同点 都可表示建议做某事,advise与suggest后面都可接名词/动名词/ that从句（should加动词原形,should可以省略）.例如：
他建议（我们）再等一会儿.
He advised/ suggested waiting a bit longer.
He advised/ suggested (our) waiting a bit longer.
He advised/ suggested that we (should) wait a bit longer.
上面的第三句可转化为：
It was suggested that we (should) wait a bit longer.
What he suggested was that we (should) wait a bit longer.
His suggestion was that we (should) wait a bit longer.
(2)不同点
①advise后可以直接跟人称代词作宾语,如：advise sb.to do sth.; advise sb.against (doing) sth.; advise sb.on/ about sth.; 而suggest后一般用suggest to sb that …形式.如：他建议我们改天再来.
[正]He advised us to come another day.
[误]He suggested us to come another day.
[误]He suggested us that we come another day.
②suggest还有“暗示、表明、指出（一个事实）”的意思.此时从句中用陈述语气,不用虚拟语气.如：
Her expression suggested pleasure.她面露喜色.
His silence could only suggest disapproval.他的沉默只能暗示反对.
