Pretty much. When I'm dieting, I can handle going heavy for one of the big three, but I'd have to follow that up with less stressful exercises. So instead of fighting through bench pressing, then squats or deadlifts, which is nuts, I'd rather do deadlifts followed by gluteham's, biceps, and lat work like chest supported rows (since my lower back is toast). Follow the logic?
Again, you diefinately shouldn't be so structured like the 5x5. Back when I was powerbuilding with IA, I'll tell you right now that I always preferred doing deadlifting LAST in my day, and usually resulted in a PR..
Chest supported rows: 4-5 sets of whatever
Incline Curls: 3 sets
Reverse Curls: 2 sets
Deadlifts: 1 x 3, 1 x 10 = Max set of three, rest 5 minutes, drop the weight and bust out at least 8, at most 12.
That example is a back/biceps/legs day. What don't you see? Any direct squatting because you'll see deadlifts more than work the legs. Add some sled dragging on your off days and you got yourself some meat for those wheels.
Now, if you're deadlifting focused for one of your lower days, guess what the other one is? Yep, free squats.
Those examples are for what I personally prefer cutting down (ie chest/shoulders/triceps; back/biceps/legs)
If you're doing full body, again, don't get in that Starr/Rippetoe mentality of 3 maximal full body compounds per day. Instead, I'd probably do something more like this: Remember, you're in fat loss mode
Day 1: Squat focus (back squats heavy)
Day 2: Bench focus(bench heavy)
Day 3: Deadlift focus (deadlifting heavy)
Day 1 you'd do your squats heavy (relatively speaking), then follow that up with MANAGABLE exercise selections. SLDL's, DB presses, dips, a shoulder isolation, and biceps
Day 2 you'd do heavy bench press, then ease back a bit by lowering the intensity and picking MANAGABLE exercise selections. Hack squats, DB shoulder press, rows, and skullcrushers
Day 3 you'd do heavy deadlifts, then ease back a bit by lowering the intensity and picking MANAGABLE exercise selections. Leg press, chest press, pullups, hammer curls
