LifeStrong tells me to eat 800 calories in order to lose weight?!?

So they're was this app that basically tracks calories and you have to punch in your weight age, height and eveything and I chose lose 2lbs in a week. I have to eat 800 calories a day in order to do that. Isn't that too little? Why so little tho? Most ppl can't even do 1,200

How to Lose Weight From Face

Recommended Answer:

That does seem too low...what is your current height and weight???Go to freedieting.com and on the menu on the left is a section for calculators...they have a "daily needs calculator"...see if that one gives you equally low numbers as you enter your age, height, weight, sex, and activity level to determine your caloric needs, then it will give you a number for maintenance, fat loss, and extreme fat loss...

Other Answers:

• It's because the 2lb/week thing is mainly for obese people who don't need that many calories in a day. If you're not obese then I'd recommend starting with 1lb a week, otherwise it could be dangerous.
• Do a low carb diet instead. Eliminate white flour (breads, cookies, etc.) starch (potatoes) and sugars. You can eat meat, eggs, salads with oil and vinegar dressing. You'll find more information on line. Don't try to live on 800 calories, that isn't enough.
• That's because of the data you input. The program merely spew out the correct number. Change the goal and the end date to fine tune it for the amount of calories you wish to eat.
• Yes it's too little. You have to understand that sort of simplistic math does not work. Yes if you really cut calories you may lose weight, but no app can give an accurate prediction of losing x pounds based on eating y calories. It doesn't work. It's never worked for anyone. The people who write those apps possess no real world data confirming that the math has ever worked.
