A 1,000 calorie diet is a risky strategy for losing weight. While someone can safely follow the diet short-term, experts do not recommend that people follow extreme diets for extended periods because they can damage a person's health and cause them to regain the weight they lost and more.
Effective At Weight Loss
If you need to shed pounds fast and don't expect the long-term result, the 1000 calorie meal plan may help you with that. As mentioned at the beginning of this article, this diet can help you lose 2-3 pounds (1-1.5 kg) a week, which is quite fast.
For weight maintenance, the Dietary Guidelines for Americans 2020–2025 suggest a range of 1,600–2,400 calories for women and 2,200–3,000 for men — so you could consider anything below these numbers a low-calorie diet.
The diet doesn't have enough calories
Eating too little — say, 1,000 calories a day — can prevent you from losing weight, too. "When you don't eat enough, your body is starving and it's not going to lose any extra weight" because it needs those energy stores to keep you alive, Fakhoury said.
For those who need fewer calories, a 1,200 calorie diet is usually safe and potentially effective. The number of calories a person needs each day depends on several factors , including their age, sex, activity level, and body size.
Most adults need a minimum of 2000 calories to sustain metabolism, muscle activity, and brain function. However, too many calories can lead to weight gain and a variety of diseases.
It's all well and good to poke fun at this mythical 'perfect; calorie deficit, but the truth is, if most people ate 1,200 calories a day (every day) they'd lose weight, and they'd do so quickly. But this doesn't mean you should. 1,200 calories is not ideal for everyone.
People may try this diet to control their food intake and lose weight. Some research suggests that the average female can limit their daily caloric intake to 1,500 calories or less to drop 1 pound per week. The average male may consume up to 2,000 calories a day to lose the same amount of weight.
You Might Get Malnutrition
Following an unbalanced 700 calorie diet for long enough can lead to malnutrition. You may not notice that your diet is unbalanced. For example, you may cut out calories from fats to meet your daily target.
Some people go on a very low-calorie diet for rapid weight loss, often consuming only 800 calories a day. This type of diet usually includes special foods such as shakes, bars, or soups to replace meals and for added vitamins. Very low-calorie diets can help a person achieve weight loss of up to 3 to 5 pounds per week.
According to studies, for every 1 kg of weight loss, 7700 calories are needed, or 1000 calories are lost 0.13 kg.
With your 1000 calorie meal plan, try to space out your meals and divide your calories throughout the day with roughly a 250-calorie breakfast, 350-calorie lunch, and 400-calorie dinner. Drink plenty of water. When you are eating so few calories per day, food quality really matters.
An aggressive calorie deficit is anything more than 30% of your current maintenance calories.
We need at least 1,500-2,000 calories in a day. By planning 10 kg weight loss in one month, we reduce it to 1,000 calories per day. To lose 10 kgs, we must note that we should burn extra calories to create a calorie deficit. With a balanced diet behaviour, include 30 minutes of physical exercise in your daily routine.
A larger person with more fat tends to have larger Total Energy Expenditure so they can have a 1000 - 1500 calorie deficit and still be okay. But, for someone who needs to lose 10 - 20 pounds of weight a large deficit could be detrimental to their weight loss as it could result in their metabolism shutting down.
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite. Also worth noting is that the human body can adapt.
Foods that are loaded with low-calorie vegetables and fruits can be included in a 500-calorie diet. You can make vegetable soup, vegetable salad, fruit salad with low-fat yogurt, or a portion of grilled chicken or fish with grilled veggies for lunch or dinner to satisfy your hunger pangs.
Generally, the recommended daily calorie intake is 2,000 calories a day for women and 2,500 for men. This is a commonly established calorie intake, making the 2000 calorie diet a standard as it hits the average intake for most adults.
So, if you're eating 1,200 calories and not losing weight, it could be that your body is really struggling to function on so little fuel and your metabolism is not functioning well enough to respond to a deficit in the way you'd like.
But the average weight loss that most people see on the 1200 calorie diet is about one to two pounds per week.”
Losing that amount of weight may improve weight-related medical conditions, including diabetes, high blood pressure, and high cholesterol. But in the long-run, very low-calorie diets aren't more effective than more modest diets.
