how is that possible then? Surely weight loss is down to the amount of calories u use up.
Ah, but are you talking about fat loss or weight loss? Fatloss should be down, but most people are more focused on what the scales say.
If you have a person who is sedentary and uses for example 1500 cal a day in energy to live and do what they do and then another person who does exercise thereby making their body need 2000 cal to exist then that person would lose more weight surely?
500 calories in exercise is a lot, especially every day...and don't believe all the exercise machines
You are already on very low calories anyway. Not sure of the science on this point, but if you are taking in 500 calories and burning 500 calories, I wouldn't have thought that would be good.
Even so, assuming metabolic rate hasn't been decreased (which it will have done), 500 a day extra in exercise every day of the week (which isn't good), will mean an extra pound.
Again, that is if metabolic rate hasn't slowed, if you don't retain water through exercise, which many people do.
Wouldn't say that from a weight loss perspective it was that great a deal.
Or is ketosis not about the amount of calories?
Ketosis is about carbs, not calories. Cambridge is a ketogenic diet that happens to be very low calorie too.
