If you have never done an exercise (e.g. running, strength training, etc), pretty much the only way is to start from zero. No risk, no trial and error.
If you have been doing it (e.g. walking), you know how far and how fast you have done it typically. That is pretty much to what extent you could do it. Again no trial and error and no risk.
Not all trial and error is risky. When you increase the intensity of an exercise, you can tell if it is too much for you, just about challenging but not too hard, or too easy. People who hurt themselves usually are those who ignore the warning signs emitted by the body, except for accidents, which happen randomly.
For food the question makes no sense. What did you mean?
For exercise, just go slow. If you think you might be able to run, don't go out and run 20 miles. Go for a light easy jog. If you're feeling fine and good with it after 10 minutes, maybe take it up a notch.
If you don't know where you are now, then start below where you think you are, and go up as you feel safely comfortable doing.
The propensity for injury is really only there if you massively OD right away, like running 20 miles because you think you might like running, or going right from couch potato to 3 hours a day at the gym, or thinking bench press seems easy and loading up 200lbs for your first attempt.
Just don't be silly about it, and you'll be fine. Give yourself time to work out where you are by building up.
If you are inquiring as to your capacity to exercise, the shortest answer is that you will figure it out by trial and error. Trial is to get moving and do something.
If you are new to exercise, the easiest is to start walking. Aim for 30 minutes 6 days a week if possible. Add stretching and strength training as you are able. If those don't work for you, the best exercise is anything that you will do consistently. How about swimming, biking, hiking, or taking an aerobics, ballet, jazz, Zumba, Yoga, or Pilates class? If those don't fit your style, you can go water skiing in summer and snow skiing in winter. Basketball, baseball, football with friends are best options for some people, but it might not be for you. Playing at a park playground and running with your chidren (if you have any) are options for some people. You will find the exercise which is of interest and practical for your lifestyle.
Error will be when you try something and are so darn sore the next day that you can hardly walk, or otherwise move. That meant that you overdid your capacity and you need to rest, recover for a day or two and get back to the dog that bit you, but at a lower intensity level.

What do you mean the "capacity for any one food"? Are you asking how to determine the maximum amount of each food a person can have without gaining weight? There is no precise number for that because there are so many factors involved.
