Is an 1800-calorie diet safe?

Answer by  t1986 (54)

It is almost impossible to say whether an 1800 calorie per day diet is safe, without knowing how tall you are. If someone who is 6'8" were to eat 1800 calories, they would certainly lose weight, to an unhealthy level. Likewise, if a 4'9" person were to eat that many calories, they would most likely gain lots of weight.

Depending on you age, gender and activity level, everyones calorie needs are different. For most people 1800 calories would probably be enough to lose weight even with a sedentary lifestyle and more than likely safe.

1800 calories is a lot. Depending on your size, you should probably be at around 1200. If you reduce to slightly above 1000 without skipping meals, overtime, you will lose weight. Just remember to exercise.
