600-700 a day diet ?

You will lose fast eating so little but it won't be fat loss. It will mainly be muscle loss. You aren't eating enough to fuel your body at rest (your heart, lungs, other organs take calories to run). Eating so little will not allow you to get proper nutrition in. Eating so little will make it so much harder to lose eventually and make it nearly impossible to maintain.

Research BMR and TDEE. Eat between those two numbers. Eating your plan of 600-700 cals through soups, shakes and fruit will lead to muscle loss, health issues, hair loss, and a lot of other issues.

Depends on how much fat you have on you.
Obese eating at or near a 50% calorie deficit burn fat first.
Lean eating at or near a 50% calorie deficit burn lean muscle.

In addition to the toll it will take on your body internally, you will have absolutely no energy. It will affect your moods and your emotions, and the likelihood you will gain the weight back when you begin to eat normally again is somewhere near 100%.

Aim for a lifestyle change, not a diet. Make healthier choices that will educate you and make you more aware of the nutritional content of the food you come into contact with, and you'll be able to take the weight off slowly-- and healthily!-- and then keep it off through good habits and smart choices!

I just started eating a 900-1000 calorie diet last week. My stress was unbelievable before, so my hair was falling out. In the past week, I have eaten less, had more energy for my workouts (treadmill, elliptical, Jacobs ladder, boxing) than before, and my mood and energy are just fine. I'm sure someone will say "but it's only been a week- wait for the long term!" - but it's working for me right now.

Oh you're going to wish you hadn't posted that. This is not the site for a very low-cal diet. MFP will not advise you to eat any less than 1,200kcal.

Pretty much. Going below 1200 stirs up a mob frenzy on MFP. I understand... I use to agree with it myself.

I eat between 700-1000 cal a day. But I have been eating like that since I was a kid. I'm 5,4 and 105-110. I'm also a competitive swimmer and a varsity badminton player. But everyone's different. I have a really small and light bone structure. My doctor gave me the approval to eat what I eat currently because of my body structure and how it functions. I think you should get a check up and ask your doctor first before changing your diet drastically.

LOL, but you can't be an outlier and not fit into the rules!!! That just isn't right! It's nice to hear someone say they don't fit into the norm and are maintaining a healthy life.

the "dr's" are out in force again today....

still love to know where the magic 1200 comes from..

i advocate lifestyle change instead of diet, but... thats personal prefference not science,

science says calories in vs calories out ...

the rest is purely opinion

Agreed. Everyone is an expert. Soon they'll be pulling out their links to articles that can be refuted with links to other articles. Look at the news -- one month coffee is bad for you and will heighten your risk of cancer, the next month coffee is good for you and will help mitigate strokes.

The numbers don't lie. Eat at a deficit and your body should shed weight. The amount of weight depends on the deficit. How quickly you lose it and your proclivity to gain it back are based on the dieting/eating styles you maintain.

I would suggest finding a new doctor. 700-1000 calories a day is not good for a sedentary person let alone one that exercises. You cannot get proper nutrition.

? A lot of Asians are my weight/height and they live to be over 80 with no health problems. My grandmother is 5.5 and 110. She is 86 and she does not have high blood pressure/diabetes whatsoever. She does tai-chi and swimming every morning still at her age. My great-grandmother lived until 92. Like I said, it totally depends on understanding YOUR OWN body. What works for me may not work for you.

Not quite understanding. Are you saying Asians typically consume 1000cals or less? If so - SHENANIGHANS!!!!
