Hey there,
It’s very common, mostly because we don’t tend to eat enough before hand, or don’t eat soon enough after a workout (if you’re at the gym, by the time you shower, change, head home and start making dinner, it’s likely you’ll be STARVING. Having a snack AT the gym can help you tons).
Change up your eating schedule to help yourself out & include a mix of carbs & proteins before your workout: carbs for energy & protein for satiety. If you’re going too long without a meal/snack before your workout, chances are you’ll be even hungrier after you’re done. Make sure you’re eating 1-2 hours before you get sweaty, and make sure it’s enough to last you past your workout (if you’re eating every 3-4 hours). I always have a snack within 15-20 minutes of my workout, which tides me over until my next meal (even if it’s only another hour or so). Otherwise, I’m famished.
We’re ALL different, but if you’re starving after a workout… it means your body needs food. You can help prevent it by eating enough beforehand, and having a little something right after your workout.
Hope this helps!
