How do I lose 15 pounds in one month on a vegetarian diet?

Please no lectures. I'm 5'7, I'm 16 years old and weigh 140 pounds. I want to be about 128 pounds before school starts and I was just wondering if anyone similar to me had some successful diet plans that they went on? I do yoga 5-6 times a week because I'm not the best at exercising hahah thanks! :)How do I lose 15 pounds in one month on a vegetarian diet?
This is how it works.



1 to lose a pound, you need a 3500 calorie deficit.



2 you need to figure out how much you are burning a day. There are some more accurate formulas out there, but at your age, with your activity level (you鈥檙e at least doing yoga), 12 calories a pound is a pretty good estimate. At 140 you are burning 1680 calories a day. When you reach your goal of 128, you will be burning 1536 calories a day. So that you don鈥檛 have to crunch the numbers every day, I would just average those 2 numbers: 1608. (If your yoga is an aggressive calorie burning yoga, then you will be able to increase these numbers.)



3 figure out how much of a calorie deficit you want in your given time period. 140-128=12 12x3500=42000 If you want to lose 12 pounds, you need a 42000 calorie deficit. If you want to lose that in 30 days, divide that number by 30. 42000/30=1400. To lose 12 pounds-from 140 to 128-you need to lose 1400 calories a day. (Those numbers change significantly depending on your starting weight and the length of time you give yourself to lose the weight)



4 if you are burning 1608 a day and want to lose 1400 of those calories then: 1608-1400=208. You can eat 208 calories a day.



That鈥檚 the math. That鈥檚 how it works.



There are lists of problems with a diet of 208 calories a day. (See Amelia鈥檚 comment) But even if you are OK with going crazy with starvation, you might not be ABLE to do it. You are hard wired to survive, and this will most likely lead to binging. Also, that 12 calories a pound metabolism estimate, on a 208 calorie diet, will SIGNIFICANTLY drop. That鈥檚 your body鈥檚 way of keeping you alive: slowing down your metabolism. And on a starvation diet you will lose as much muscle as fat, which defeats the purpose.



Two real options:



1. extend that 30 day goal to a 103 day goal. 42000/103=407.76 You would need a 408 calorie deficit a day to achieve this. 1608-408=1200 If you extend your diet to 103 days, you can eat 1200 calories a day. You wouldn鈥檛 have to increase your exercise level, and you would attain your goal just before thanksgiving.



2. If you REALLY REALLY want to lose the 12 pounds in 30 days, and will do anything to obtain it, there is a solution. You will still need to eat 1200 calories a day, but you have to burn the difference between 208 and 1200 calories. So you would need to exercise off (1200-208=992) 992 calories a day. 1200 calories a day is kind of a magic number, because if you are filling your diet with lots of fruits and Green vegetables, you can eat constantly. The trick to staying on a diet is NEVER letting yourself get hungry. This can be achieved on a 1200 calorie diet, any lower and you risk allowing yourself to get hungry. This is even harder if you are adding enough exercise to burn an additional 992 calories a day. The extra exercise will increase your appetite. You need to constantly be eating super healthy, low calorie foods. You cannot let yourself get hungry. So, how do you burn 992 calories? The estimate is to do two and a half hours to three hours of cardio a day. This is assuming an aggressive cardio, wherein you are sweating and your heart rate is up: Jogging, swimming, high impact aerobics. You could definitely burn 992 calories in less than two and a half hours, but it depends on so many factors. I鈥檓 assuming your pace is not that of an athlete or someone who trains in the gym every day. I don鈥檛 see any problem with being a vegetarian on a 1200 calorie a day diet. The problem is getting that two to three hours of exercise a day. This is still considered a risky hard core diet. Losing that much weight in such a small time requires a hard core obsessive desire to attain your goal. (mini lecture so that I can feel better after suggesting such a hard core diet to a 16 year old: even if you are eating 1200 a day, if you are exercising that much, you are in dangerous diet territory. At 16, you should choose much more gentle diet options! Why not make your goal to lose 12 pounds b4 thanksgiving?)



If you are interested in one of the above two real options, whether the reasonable one or the hard core scary one, and you don鈥檛 know what you should eat, I can help you with that too. However, I鈥檝e been extremely long winded here. So I will only go off on that information if you ask me to.
I just lost 15 lbs in one month by eating 400-500 calories a day, exercising constantly, and thinking about food non-stop. DON'T DO IT. Trust me, it was terrible - losing weight that fast makes you feel unbelievably weak and dizzy (towards the end, it took a huge amount of effort just to walk a flight of stairs) and you waste all your time thinking about food. 5'7" and 140 lbs sounds fine, you don't need to lose weight! If you want to though, try losing 5 lbs, NOT 15.

(I know you said no lectures, but I'm not counting this as a lecture, I'm just telling you what to expect. And it's horrible.)

For the record, I also happen to be 16 and I'm 5'8" and started out at a pretty similar weight (129 lbs to 114).How do I lose 15 pounds in one month on a vegetarian diet?
well...if you cut out a ton of calories it is definitely possible, but you don't exactly feel great while your doing it.

i did that to lose weight once (i cut out meat, dairy, and most carbs) and my hair got really thin and i was cold all the time...hence iron defeiceny(spelled that wrong? haha).



if you're not too worried about your health, then eat mainly vegetables and fruit but also eat protein like tofu, beans, tempeh, etc. garbanzo beans are really good for you and have iron, and so are avocados. almonds are good for protein too and healthy fats.

good luck! remember veggies veggies veggies. oh and lots of fruit. try to eat most of your carbs in the morning. the problem with most veggies trying to lose weight is that they eat more carbs...eat more protein!
hahahhaha you cant lose 15 pounds on diet alone. you'd need rigorous exercising... good luck %26lt;.%26lt;How do I lose 15 pounds in one month on a vegetarian diet?
gawd, just order some spanx and call it a day, you can shave off a good 15 pounds with spandex, trust me
