Weight loss after workout

Is it normal to be 4 or 5 pound lighter after a hard workout or does it mean i haven’t ate or drank enough during workout ?

I usually am as well much lighter. And I drink a bottle an hour, with carbs and electrolytes in it

It’s very normal. I can lose 4KG on a very hot day, even whilst trying to drink the water lost back.

That’s because even the glycogen / fat you are burning is being turned into CO2 / H2O, but most of the weight loss is just water

4lbs is pretty much the weight of one half gallon of water. from what I can tell from my water bottles they are around 22 to 24 ounces, so it would seem reasonable that one would weigh around 2 pounds less after each hour if only consuming one bottle per hour.

Glycogen is bound up with water in your muscles. When you burn glycogen you lose the water weight. This is why when people go on a low carb diet they quickly lose 10 pounds and get all excited.

I have that happen when I run, I can be anywhere from 2-8lbs lighter. However on the bike (trainer ride) I usually am heavier. I do consume a lot of water on a trainer ride however, not uncommon for me to drink 1.5-2L (3-4lbs) of water per hour.

I wouldn’t put too much stock into it unless your planning on many hours of activity were finding out sweat rate and subsequently calorie/mineral/electrolyte intake becomes a larger issue.

the workout is really important if someone is on a weight loss journey. amino acids protein foods like meat, poultry, fish, dairy, soy, legumes, buckwheat, quinoa, etc.; or, even though dietary supplements help us for weight loss. If you are on a weight loss journey.

Oddly I often find I have a distended belly after working out - it looks as if I have had a few beers. There does seem to be a few articles about this saying it is not too unusual and is due to a rise in cortisol through exercise which causes water retention and bloating
