A 1000-calorie diet is specifically designed for rapid weight loss, and the logic behind this plan is simple. Give your body fewer calories, and you are bound to lose weight rapidly, even with little or no exercise. As part of this diet, you take limited carbohydrates, lean protein, and more vegetables and fruits that offer fewer calories. According to studies, this caloric deficit diet may help you lose weight by 8% on average, but the approach is only short-term (1).

Barbara Kovalenko, a nutrition consultant, says, “Eating 1,000 calories per day can cause weight loss, but it depends on a variety of factors, such as your starting weight, muscle mass, and activity level. It is also important to note that a calorie deficit alone is not always the most effective way to lose weight and maintain a healthy lifestyle.”
She adds, “Gaining weight while eating 1,000 calories per day could be due to a variety of factors, such as underreporting calorie intake, overeating on high-calorie foods, or not being active enough. It’s important to consult a healthcare professional or registered dietitian to determine the best plan for you.” Keep reading to know more!

Note: Consult a nutritionist or a doctor before taking up this diet as it requires a drastic caloric restriction.

How Much Weight Will You Lose On 1000 Calories A Day?

Consuming 1000 calories a day usually creates a significant calorie deficit and results in weight loss. A pound of body weight is roughly equivalent to 3500 calories. Hence, if you consume just 1000 calories a day, you may approximately lose 1 pound per week. However, approach such a low-calorie diet with caution. Severe calorie restriction, while possibly lowering body weight and improving body composition, can also lead to nutritional deficiencies and cause other adverse effects (12). Consult a healthcare professional for a balanced, personalized, and sustainable approach to weight loss.

Note: With a 1000-calorie diet, you can reduce up to 8% of your present weight. Every body type is different, so weight loss may vary from anywhere between 5 pounds to 10 pounds.

Nicholas, a fitness content creator, tried a 1000-calorie-per-day diet along with a proper workout for 12 days. He noticed a 1-and-a-half inch weight loss. He said “12 days of dieting even on an aggressive cut was not hard for me at all. I didn’t feel like I was sacrificing or missing out on a ton of things (i)”.

Following this diet under expert guidance can yield some health benefits. Find out what they are in the next section.

Does The 1000 Calorie Diet Plan Work? What Samantha Blanton, RDN, Says

According to Samantha Blanton, RDN, “Decreasing your calorie intake to 1,000 calories per day will most likely result in rapid weight loss. But unfortunately, it can also cause drastic damage to your body if adhered to long-term.”

“The average adult has a basal metabolic rate (BMR) of 1,400-1,800, depending on if you’re male or female. When you decrease your calorie intake below your BMR for an extended period, it may cause significant damage, such as slowing your metabolism by increasing muscle loss. Another complication the 1,000-calorie diet may cause is fatigue and weakness. It may result in side effects, such as feeling chronically tired, weak, and unable to perform certain exercises.”

She adds, “There are many other complications that may occur while on the 1,000-calorie diet, such as nutrient deficiencies. Due to the likelihood of potential damage it can cause, I highly recommend you seek out a health professional, such as a registered dietitian, before adhering to the 1,000 calorie diet on your own.”

What Should You Follow?

Follow the diet for not more than 10 days.Do not overeat.
Consult your doctor before following the 1000-calorie diet.Avoid alcohol and sweetened and carbonated beverages.
Go for medium-paced walks and light exercises.Do not sit in one place for too long.
Include lots of fresh fruits and veggies in your diet.Do not skip any of the meals.
Consume a good amount of proteins to build your muscle strength.Do not take stress if you have gone a little above 1000 calories one day. Skip the bowl of watermelon the next day and have a cup of green tea instead.
Drink enough water.Do not stay awake late at night.

Note: As it is a low-calorie diet plan, you must consume multivitamin and mineral supplements along with vitamin D3. Always consult a doctor before taking any supplements. Also, consult your doctor before combining the low-carb diet with intermittent fasting.

The 1,000-calorie diet helps you lose weight rapidly, provided it has a good balance of macro and micronutrients. It is a low-fat, low-carb, and moderate protein diet that comprises mostly fruits, vegetables, and lean protein like chicken breast and seafood. However, this diet has to be followed under the supervision of a certified dietitian, as an imbalanced low-calorie diet can slow down metabolic rate and cause fatigue, dehydration, hair loss, and muscle loss. Moreover, it is not recommended to do high-impact exercises on this diet. However, you can go on a 30-minute medium-paced walk or do low-impact exercises. So, is 1000 calories a day good? It can be effective for rapid weight loss, but it is important to consult a healthcare professional to determine if it is safe and appropriate for your individual needs and health goals.

Frequently Asked Questions

Why am I not losing weight although I am eating 1,000 calories a day?

Mary Sabat, RDN, says, “If an individual is not losing weight after eating 1000 calories a day, it could be because of several factors, such as lack of physical activity, an unhealthy diet, hormonal imbalances, or other health conditions.”

How many pounds can you lose if you go on a 1000-calorie diet?

With a 1000-calorie diet, you can reduce up to 8% of your present weight. Every body type is different, so weight loss may vary from anywhere between 5 pounds to 10 pounds.

What lean proteins can I have while on the 1000-calorie diet?

You can have skinless chicken, turkey, fish, button mushrooms, and lentils. Avoid beans, tofu, beef, and pork.

I weigh 250 lbs and want to lose weight quickly. Can I go on the 1000-calorie diet for a month?

Depending on your body type, metabolic rate, genetics, age, and medical history, you need to follow a diet that will not harm your body in the long term. Exercising is a healthy option to start with. If you starve yourself, you will gain weight instead of losing it. Seek your doctor’s advice so that your calorie intake is reduced gradually.

Can I lose weight without exercising if I am on the 1000-calorie diet?

Since the 1000-calorie diet has way lesser calories than what you should normally intake, you can pretty much do without exercising. Do some stretching and medium-paced walks to maintain your blood circulation and muscle strength.

I am a breastfeeding mother. Is the 1000-calorie diet right for me?

If you are breastfeeding, it is not advisable to go on a low-calorie or very low-calorie diet. You should consult your doctor or dietitian to know whether you can go on a low-calorie diet so soon.

Can I have a cheat day while on the 1000-calorie diet?

Yes, you can. Make sure you eat in less portions. This will help you the next day. If you eat about 2000 calories (or more), and the next day you want to fast, that is not an option and is not recommended at all. Once a week, you can have slightly more than 1000 calories, say 1300-1400 calories. Nullify the effect by sticking to the diet and drinking green tea at least twice a day for the next two days.
