Hi! Thank you :)!
Which cross country sport(s) will you be doing? if I’m right there are a lot!
Anyway the only way to lose weight is to exercise (expecially cardio) and eating healthy and less than the usual! Maybe you can try things like eating smaller but more frequent meals. If you’re doing things like cycling and running you’re already set with exercise.
Remember to not overdo it, give it time and keep it healthy.
If you’re going to use up a lot of energy you won’t really need to eat a lot less since you will be burning it off with exercise (so also make sure that you’re eating enough). They will understand since they probably know that you can’t lose weight healthily in a short amount of time.
Sure ask, I’ll see if I can help :).
It might be water retention, this happens if you don’t drink enough water, so it might explain it since you’re starting to drink more.
Or you might have actually lost that 1lb- maybe from being sick, or your body just needing more energy than the usual or you eating less than the usual without really noticing.
Anyway people do gain and lose a bit of weight around the year without them really trying (change in habits, holidays, etc).
