1100 Calories A Day: Scaling Back Your Caloric Intake To Nix Those Extra Pounds

What Do We Know About The 1100 Calories A Day Diet?

Dieting and losing weight in general is a numbers game, in which you calculate the exact number of calories you need to both consume and burn. These numbers are often stated in the names of diets, letting people understand what to expect from them. One of those such diets is the 1,100-calories-a-day one, with which you have to eat the stated number of calories on a daily basis, regardless of your daily norm. Consequently, since women’s bodies naturally need less calories to function properly this diet is easier for women to follow. 


Eating 1,100 calories a day is not the most extreme form of dieting, which may make it safer than a number of other meal plans. That being said, it might be not suitable for certain groups of people. So, let’s get into looking at what’s involved in the 1,100-calories-a-day diet to identify its potential risks and the best strategies for enhancing your dieting experience.

What Happens If You Eat 1100 Calories A Day?

First off, a 1,100-calorie diet is classified as a low-calorie meal plan, meaning it involves eating less calories than your body needs. Basically, on a low-calorie diet, the daily calorie intake makes up 1,000-1,500 calories. By eating only 1,100 calories a day, you create a caloric deficit, which is a condition that can ultimately result in weight loss. As a consequence of normal activity, you will be burning more calories than you consume and this is a natural way to shed pounds.


In the state of the caloric deficit, your body is looking for the alternative energy sources to ensure the proper functioning of the body systems. Fat deposits in different areas of the body are the best alternative energy reserves to fuel you up. As your body converts fat into energy, you will be losing weight (3). 

However, it is not recommended to jump into the 1,100-calories-a-day diet without preliminary preparation and expert’s consultation. Since each body is unique, the one-size-fits-all approach will not work here. 1,100 calories is less than most people need in a day to stay healthy and get in all the nutrients they require. Low calorie diets in general may be even more risky for those with certain medical conditions or histories.  So, if you decide to try this diet, you should first consult your doctor and dietician and undergo a physical examination (10).

What Is The Normal Daily Calorie Intake?

Depending on their age, BMI, and sex, people require different numbers of calories. According to the Dietary Guidelines for Americans, the calorie intake for women should make up between 1,600-2,400 calories and a bit more for men – 2,000-3,000 calories (1). 

On the 1,100-calorie diet, the number of pounds you lose will depend on the number of calories you need to maintain your weight. 1 pound of fat equals 3,500 calories, which is the main criterion you should consider when creating a 1,100-calorie-a-day meal plan (1). For example, if you are aiming at a rate of 2 pounds lost a week, which is the maximum recommended to shed a week (9), you will need to create a weekly 7,000-caloric deficit. On a daily basis this means you will be looking at cutting back on your daily caloric intake by 1,000 calories a day.

What To Eat For 1100 Calories A Day?

Once you have made up your mind and cleared it with your doctor to try a low-calorie diet, the “what to eat” question becomes especially relevant. As its name suggests, the 1,100-calories-a-day diet consists of eating no more than this number of calories. However what exactly you will be eating is pretty flexible as nothing is said about the food choices for this meal plan. So then, you might ask yourself: should I even restrict myself in what I eat?

The answer is definitely “yes.” Since you are not allowed to exceed 1,100 calories a day, it is crucial for you to eat products that are both nutritious and low in calories. Here’s the list of foods with which you can substitute for those that are neither compatible nor suitable for the meal plan:

  • Fruits and veggies. As food sources which are rich in nutrients and fiber, these will help you curb your appetite (10).
  • Lean protein foods and low-fat dairy. These include fish, skinless chicken, skimmed milk, etc., all of which are rich in protein that facilitates weight-loss (10). 
  • Whole grains. Besides being rich in complex carbohydrates, whole grains contain a great number of nutrients, antioxidants, vitamins, and minerals, which are essential for a substantial meal (8, 10)
  • Herbs and spices. These add flavor to your food without adding calories. Just beware of spice blends that may be high in sodium, which can contribute to weight gain (4, 7).

What To Do On The 1100-Calories-A-Day Diet?

To create a caloric deficit, eating less than you need is not the only thing that you can be doing. Along with that, you can engage in some other weight loss practices, such as physical activity. Getting active is always a healthy and effective way to burn calories. Vigorous physical activities, including jogging, swimming, skiing, and competitive sports can work miracles for your body. Likewise, you can make use of the high-intensity workouts that will make your fat melt. Usually, after an hour of such workouts, you burn 400-600 or even more calories. If you do regularly practice such high intensity, high calorie-burning workouts, however, eating only 1,100 calories on those days may not be enough to stay healthy.

If you are too busy throughout each day and so hardly have the time and willingness to do high-intensity workouts, you can still find other ways to make your lifestyle more active. Even such a non-demanding activity as brisk walking for 20-30 minutes, can have an invaluable impact on your weight management. Other activities of moderate-intensity include stretching, dancing, and hiking. An hour of any one of these can burn up to 400 calories at a time (6).

In addition, if you are used to commuting by car, you should think about walking the distance instead. Likewise, if you usually use an elevator, try walking up and down the staircase, as this is already considered a moderate-intensity physical activity.  

Overall, the easiest and most effective way to create a caloric deficit is to combine physical activity and dieting. In other words, to burn 600 calories a day, you do not necessarily have to do that all through restricting your caloric intake. For example, you can eat 300 calories less than usual and at the same time burn another 300 calories through moderate-intensity exercises.

Is Eating 1100 Calories A Day Healthy?

The 1,100-calories-a-day diet can be unhealthy for your body primarily because you do not get the necessary number of nutrients. Undereating minerals, vitamins, macros, and fiber can result in malnutrition, which negatively affects your body systems. For instance, when following a 1,100-calories-a-day meal plan, you risk losing muscle. Similarly, due to the lack of minerals, calcium in particular, your bones can get fragile, which in the long run might result in osteoporosis and fractures.

Furthermore, when you do not get enough nutrients, your metabolism slows down, and your body enters the survival mode. By doing this, your body stores energy to fulfil the essential functions. Gallstones are another problem you might face when eating around 1,100 calories a day. These cause acute abdominal pain, which can be eliminated only through surgery (2).

Another area that might suffer as a result of the 1,100-calories-a-day diet is your nervous system and brainwork. As you eat fewer calories, you receive insufficient fuel (glucose) for your body to run on. Consequently, if you stick to the 1,100-calories-a-day meal plan, you should not get surprised when you feel that your brain is not performing to its full potential. Plus, you might feel constantly exhausted (2).

Key Takeaways

Being classified as low-calorie, the 1,100-calories-a-day diet involves under eating and restricting yourself in the choice of food. On this diet, you are creating the caloric deficit necessary for weight loss. Of course this will depend on your weight and current caloric intake. In any case, you will have to calculate the number of calories you eat on the daily to avoid exceeding the required one. 

Although it is not necessary to restrict yourself in food choice on the 1,100-calories-a-day diet, it is recommended to do so for better meal planning. The products you should eat include fruits and vegetables, whole grains, non-fat dairy, lean protein, and herbs and spices.
