How much weight can you lose by not eating for a month?
Well, there’s no way to give a real direct answer. If we assume that you weigh 150 lbs you would need approximately 2100 calories a day to maintain your weight. If you stopped eating entirely you could theoretically lose about 2/3rds of a pound per day. So, in 30 days, without any additional exercise or activity you’d lose approximately 18 pounds.However, if you stop eating, your body will rather quickly go into starvation mode. You need to eat a minimum of 1000 to 1200 calories a day or your body will shut down. Not a wise, nor healthy choice, and virtually impossible to maintain. Your body would very quickly rebound and most likely gain even more weight.
How much weight will I lose by not eating for a week?
I did this once, well I didn’t eat for 10 days. I made sure to keep pretty hydrated and probably excersised about 1–2 hours on average a day. I lost 5kg and I also lost my period. I didn’t notice any other physical changes although when I did start eating normally again (because I didn’t have an eating disorder but a more complicated psychological problem) I gained back all of the weight I lost in about a week, eating normally so about 2000 calories a day because of messing up my metabolism.I wouldn’t recommend doing this as after a few days I stopped feeling normal hunger and instead would get extremely painful cramps and pains in my stomach for around 15 minutes a couple of times a day. I got out of breathe from even walking, was very dizzy all of the time (honestly surprised I didn’t faint)They also wanted to send me into a hospital but luckily I started eating again so avoided being an inpatient. All in all you probably shouldn’t do this but if you do I lost about 5 kg but I don’t know if you would loose a similar amount or not

It can be roughly calculated through this toolBMI Calculatoror this toolFitness Me - Android Apps on Google PlayIt base on you Basal Metabolic Rate (which is the minimum energy required to maintain your existence activity, heart beat, breath, urination…), your weight and height, your gender to calculate required daily calories intake.If you eat 2000 calories a day, and don’t take serious activity, i guest that you may weight 65 kg (I also guess that your height is 165 cm). It my estimation is correct, you may need around 2000 calories to maintain your current weight with with light activity (playing sport 1 - 3 times/week - most people do this scheme).Every 500 calories you cut down from the 2000 calories/day, you can lose 0.5 kg (or almost 1 pound) per week.If you cut down completely 2000 calories/day for one day, technically you can lose 0.25 kg if the next day, you don’t make it up.However, it quite ridiculous with that diet plan because nobody lose weight just by skip eating for one day. Take diet plan together with workout plan to lose weight healthily.
Do you lose weight if you don't eat?
One way to lose weight is to just stop eating. It sounds simple, but in reality you have to know what you are doing to get any long term weight loss benefits from fasting. Let's look at the weakness and strengths of fasting for weight loss.Like most forms of dieting, fasting can be used to bring about dramatic but temporary reductions of weight. You can go on a long fast, taking nothing but juice or eating grapes or taking some other low calorie meal substitute for several weeks, and while you are on the fast you will certainly lose weight. However, during the fast you may not be able to carry on your normal social interactions. It's not so easy to sit around sipping carrot juice while the rest of your family is eating a normal meal.Another problem with long fasting is that your body requires vital nutrients (vitamins, minerals, protein) and your favorite juice may not contain them. Long fasting without proper medical supervision can be dangerous.Finally, a major problem with this kind of fasting is that once you stop fasting and resume eating your normal diet, you are likely to gain back all the weight that you have lost during your crash weight loss fast.So, does fasting have any place in a weight loss plan? Yes it does. Periodic fasting is one of the secrets of a long and healthy life. Our body's digestive organs require a rest from time to time,just as we require days off from work. One-day fasting done in a methodical and regular manner provides the kind of rest that helps our digestive system, aids in the elimination of toxins from our body, and, yes, also helps us to lose weight in a healthy and sustainable.Tips for weight loss
How much weight will I lose if I don't eat for 12 days and only drink water, if I weigh 97 lbs now?
You will lose lots and lots of water weight (maybe 20 lbs) if you do not go low carb (max.30g a day) for, say, 1–2 weeks beforehand.But that is irrelevant since the water weight will come back once you start eating carbs again after the fast.In terms of how much weight from fat and muscle you will lose, it depends. If you are in ketosis first (see above) you will not lose any muscle. You can use ketogenic supplements like BHB salts and MCT powder to help speed up the process and to get through the transition more easily.Then, in terms of only losing fat, you will basically lose whatever your BMR is. If your BMR is 1500kcal, say, that will be your daily deficit.This calculator will give you a good estimate after you have entered your values: Pennington Biomedical Research CenterYou will not feel much in terms of hunger pangs if you are in ketosis. You can measure the depth of ketosis with the Abbot Precision Xtra device (be ware that test strips are expensive). That device is the only option on the market as of this date 14.Sept.17However, you will feel very, very low on energy. You will experience what it must be like to be a very old person. It’s an interesting experience but you will probably not be able to be very productive. So walking outside and watching movies/series would be best.YOU MUST TAKE PHOSPHORUS every day, 1g per day. Otherwise you could DIE from Refeeding Syndrome (google it). You should also put salt in your water and supplement with magnesium and potassium to get the other electrolytes. If you do that, fasting isn’t dangerous. Worst case, you could feel a bit dizy getting up too quickly and fall.Going low carb, and with a calorie deficit of 1000kcal per day via exercise and nutrition, would probably be an easier alternative and you will lose weight quickly.Cheers
How much weight will I lose if I don't eat for 5 days?
Not enough to justify what you will do to your body in the process.In terms of real weight, it will be somewhere between 3/8 and 3/4 pounds per day. It will depend on how big you are in the first place, and how active you are during those five days - although after the first day or two that’s almost certainly going to be “not active at all”.When you step on the scale, you will probably find that it’s more than what I’ve predicted, but that’s only going to be from the effects of having emptied out your digestive system and of dehydration, and it might turn out to be less if you bloat up from overhydration. The real weight loss, which is only the tissue that has been metabolized to keep your heart, brain and other vital organs functioning despite the lack of nutrition, will be within the range that I said it is.Starving yourself is a terrible way to lose weight. It hardly ever leads to permanent weight loss - except, of course, in the case where you do so much damage to your body that you permanently impair or kill yourself. Even if you don’t go that far, the lack of essential nutrients harms your body in numerous ways. Don’t do it. If you’re thinking of ignoring this advice, then you’ll probably ignore my next bit of advice, too: see a therapist.
