Trained individual on a reasonable diet, taking an intelligent approach to cutting will lose &#x27;some&#x27; strength and &#x27;some&#x27; muscle when cutting body fat, yes.<p>Someone who is out of shape might actually be able to gain both muscle and strength while losing weight when starting out as long as they are lifting in addition to cleaning up their diet&#x2F;reducing calories. The less fit they are the better the gains, which I guess is borderline captn obvious territory :)
