1200 calorie diet: who it's for and who it isn't

“1,200 calorie meal plan” is one of the most common searches when people want to lose weight. The honest answer: for most people it's too little. Here's why, and how to find your own number.

In short: 1,200 kcal is the lowest limit for women without a doctor's supervision, not a target. For most women the safe number for losing weight is 1,400–1,800 kcal, and for men it's higher still. Check your number →

Why 1,200 kcal is too little for most people

Even lying down all day, your body uses energy for your heartbeat, breathing, brain and body temperature. This is called your basal metabolic rate (BMR). For example:

  • a woman, 35, 168 cm, 75 kg, has a BMR of about 1,460 kcal;
  • a woman, 55, 160 cm, 70 kg, has a BMR of about 1,260 kcal;
  • a man, 40, 180 cm, 90 kg, has a BMR of about 1,830 kcal.

When you eat less than your BMR, your body is short of energy even for its basic functions. You're then more likely to feel tired and cold and find it hard to concentrate, and you lose muscle along with fat. That's why Dumpli never plans below your BMR.

Who 1,200 kcal might suit

For a petite, older woman who doesn't move much and whose BMR is about 1,200 kcal or less, a 1,200 kcal target can be realistic and safe. But even then, it matters to have:

  • enough protein – about 1.2–1.6 g per kilogram of body weight (protein calculator);
  • plenty of vegetables – so you get vitamins, minerals and fibre;
  • breaks – don't keep going too long without one: every few months, it's worth spending some time at maintenance.

What to eat instead of a “1,200 calorie plan from the internet”

A one-size-fits-all plan doesn't know your height, age or how much you move. It's better to work out your own number and then choose meals to match it. For example:

Signs you're eating too little

  • constant hunger, thinking about food all day;
  • tiredness, dizziness, irritability;
  • poor sleep, feeling cold;
  • overeating in the evenings or at weekends after “perfect” days;
  • for women – irregular or missed periods.

If you recognise yourself, increase your calories to a safe level. If your periods have stopped or you feel dizzy, see a doctor.

When to talk to a doctor first

Before you change how you eat to lose weight, talk to your doctor first if:

  • you are pregnant or breastfeeding;
  • you have diabetes or take medicines that affect your blood sugar;
  • you have kidney disease, heart disease or another long-term condition;
  • you are under 18;
  • you have or have had an eating disorder;
  • you are losing weight without trying.

If your relationship with food worries you, you can talk to a doctor or a psychologist. If you're struggling right now, call your local emergency number or find a free helpline at findahelpline.com.

Frequently asked questions

Is 1,200 calories a day too little?

For most adult women, yes, because their basal metabolic rate (what the body uses at rest) is already higher than 1,200 kcal. For men, 1,200 kcal is almost always too little. It only suits a small number of petite women who don't move much.

How much will I lose in a month on 1,200 calories?

That depends on your needs. If you need 1,900 kcal to maintain your weight, a 700 kcal deficit would in theory give you about 2.5 kg a month, but some of the first kilos will be water, and a deficit that big is hard to keep up. A smaller deficit often gives a better long-term result.

Why are there so many 1,200 calorie plans online?

Because 1,200 kcal is often given as the lowest limit for women without a doctor's supervision. It's a limit, not a target. For most people, the safe number for losing weight is higher.

Does Dumpli make 1,200 calorie meal plans?

Only if your calculated safe number is that, and it isn't lower than your basal metabolic rate. We never make plans below 1,200 kcal for women or 1,500 kcal for men.
