HI, thanks for using healthcare magic

Using only 400 to 700 calories daily would not be healthy, your body would not be able to sustain itself at that level.

Using a calorie calculator available online, for you to maintain a weight of 128 with only minimal physical activity, you can consume 1900 calories daily.
This is the amount of calories to maintain this weight with light exercise, if you exercise more than this then you can consume more calories.

If you continue to use only 400 to 700 calories then you would have very very significant weight loss and there would also be other significant effects on your body due to the decreased energy supply.

I hope this helps
