Not sure if anyone will have an answer to this one but here goes- lets say i do 30min of high intensity cardio and burn like 500cals by whats reading on the machine, but how many more calories are you burning when takin the ECA stack?
its not a huge amoyunt more total calories.
where the difference lies is where those calories are coming from
a product like eca does boost metabolism a bit, but its main fat loss benefits is that it shifts you much more over to burning body at, then buring carbs and potentially muscle.
so maybe normaly you burn 100 cals from fat, 350 from carbs, and 50 from muscle. with eca you might burn 200 fat, 300 carbs 0 muscle.
