How long do you need to starve yourself to lose a stone?

Answer 1

Never starve yourself for weight loss!!! Going in starvation is for another purpose, first and foremost for purification and medical intentions.

So, you're better off by executing a certain diet, whereby diet doesn't mean eating only stuff that you don't like or some program tells you to eat. No, not at all.

Diet means to change your current nutritional intake. You can still eat almost everything but the trick is "when to eat what and how much?". Find some good information in the related link below.

The first thing that happens when people starve is that they lose mostly water. Also it depends on your physical appearance and body fat fraction in stuff of how much you can lose in what time.

So to lose a stone (6.3 kg) for a 11.8 stone (75 kg) male person it would take about - by going into starvation (but we talked about that above) - it would take proximately two weeks!

Your body burns fat, glycogen and protein. Your glycogen repository is gone after two to three days. A 100 grams of body fat gives your body 913 kcal. So if your individual BMR (Basal Metabolic Rate) is let's say 2.000 kcal per day, then your body takes half from fat and half from proteins. Proteins are mostly in your muscle cells.

So in this case your body burns 1.000 calories from body fat and another 1.000 kcal from protein. Fat would be 110 grams about and protein around 250 grams. Makes 360 total.

So in this case you lose 360 grams per day dry mass and of course some water. All together maybe 500 grams or half a kilo or one pound or 0.08 stone.

Comes up to 3.5 kg or a little more than half a stone in seven days/one week.

So with the first leachate in the first couple of days it will take you between 10 and 2 days to lose a stone of body weight.
