If your goal is to lose ten pounds, this diet should not be your first option. It is very restrictive. However, it has some interesting points that you can consider on your weight loss journey.

What is Dr. Now’s diet?

Dr. Now’s diet is a low-calorie, high-protein diet that is low in carbs and fat. Even though it is very hard to follow, it was prescribed to all the My 600-lb Life TV show participants. Here is why.

First of all, Dr. Nowzaradan wanted to decrease the risks during the surgery. To do so, he wanted his morbidly obese patients to lose 10% of their body weight on their own. The main goal of such a weight loss was to shrink the patients’ liver to increase the security of the surgery. Low-calorie pre-surgery diets are often used by surgeons who provide bariatric surgery.

The second reason for such a restrictive diet was to ensure that the patients about to get the surgery were 100% committed. The thing is, the post-surgery diet is very restrictive too, and surgeons must be sure that their patients are able and willing to follow it.

When the stakes are that high, you can understand why Dr. Now was quite rough with those of his patients who didn’t want to follow the diet.

But should you follow Dr. Now’s diet? Check out its main principles to find it out. And remember that before trying any kind of severely restrictive diet, you should consult your health provider! Only your doctor can tell you if a particular diet is beneficial or harmful for your health.

The main principles of the 1200-calorie diet

According to Dr. Now’s book, The Scale Does Not Lie, People Do, you should consider three main factors when trying to lose weight. They can be joined in the acronym FAT. “F” for frequency (of meals), “A” for the amount (of food), and “T” for type (of products). 

Frequency

Regarding the frequency of meals, Dr. Now had one and only recommendation to his patients: Avoid snacking. There should be only three square meals a day. Or even two, if this is more convenient to his patients.

Amount

As for the amount of food on your plate, Dr. Nowzaradan told his patients to have no more than 1200 calories a day. This is an extremely low number of calories, especially for someone who weighs about six hundred pounds.

Type

Type of food also matters a lot. To make a very low-calorie diet a bit more bearable, you have to pay attention to what you eat. Dr. Now asked his patients to focus on two main groups of food: lean protein sources and non-starchy vegetables.

Forbidden food

As in most cases, Dr. Now worked with people who struggled to control themselves around food, it was necessary to set strict rules about highly-palatable foods. This is a list of products Dr. Now’s patients were not allowed to eat:

  • Sugar or sugary treats
  • Alcohol
  • Fruit juices and fruits with a high glycemic index (like bananas, watermelon, grapes, dried fruits, etc.)
  • Chocolate
  • Crackers
  • Popcorn
  • Pasta and noodles
  • Bread
  • Any kind of cereals
  • Nuts and nut butter
  • Sodas and sugary drinks
  • Sports shakes

Consumption of some foods had to be strongly limited. Dr. Now asked his patients to be careful with corn, dry beans, potatoes, sweet potatoes, and winter squash. These are starchy vegetables that should be avoided during the diet.

Dr. Nowzaradan 1200 diet plan example

Even though every patient had a customized meal plan, these plans were not specific. 

For example, a patient would get a list of lean protein sources. It can be poultry, fish, pork, veal, or lamb with fat trimmed. It can be steak, cutlet, rib chop, or flank steak. 

There will also be a list of vegetables, like carrots, broccoli, artichoke, asparagus, eggplant, mushroom, greens, spinach, tomato, cucumber, pea pods, zucchini, etc.

There will be oil sources stating that one portion of fat equals 8-10 olives, 10 peanuts, 1 teaspoon of olive oil, 1 tablespoon of low-fat mayo, 2 tablespoons of cream cheese, 1 slice of bacon, 2 tablespoons of sour cream, etc.

Here are several examples of high-volume, low-calorie meals you can get to fit in 1200 calories a day.

Disadvantages of the Dr. Now diet

We remind you that Dr. Nowzaradan’s diet was developed for a particular type of individual, people who’re going to have weight loss surgery. It is not for everyone, and it has a list of disadvantages. Here’s what can happen if you follow this diet without prior consultation with your doctor.

High risks of gaining weight back. Overly restrictive diets often lead to weight regain(1). This is explained by psychological and social factors, changes in the balance of hunger and satiety hormones(2), and metabolic adaptation(3) to weight loss.

Micronutrient deficiency. Even though Dr. Now’s diet emphasizes the quality of food you’re eating, not only its quantity, it still can result in some vital vitamins and minerals deficiency(4). This might happen simply because of the small variety of food one can eat on a restrictive low-calorie diet.

Microbiome changes. Studies(5) show that severely restrictive diets and bariatric surgery reduce microbiome diversity and can drastically affect colon health. Of course, when we talk about morbidly obese patients, this is often a risk you have to face. However, if your goal is to lose ten to twenty pounds, you should know that there are other ways to lose weight without risking your health.

What diet does Dr. Nowzaradan use?

Dr. Now is using a low-calorie diet that is high in protein, low in fat, and low in carbohydrates.

What do 1200 calories look like?

1200 calories are not that much. However, if you get these calories from calorie-dense sources, you can make this diet even harder to follow.

For example, you can get your daily 1200 calories from McDonald’s Double Cheeseburger, medium Fries, Baked Apple Pie, and Caramel Cappucino.

You can also get 1200 calories from half a pepperoni pizza and a pint of beer.

Or, you can follow Dr. Now recommendations and make lean protein and vegetables your primary sources of calories. By doing so, you will drastically increase the amount of food you can eat.

How much weight can I lose following the Dr. Now diet?

Anyone will lose weight on a 1200-calorie diet. For morbidly obese patients, the weight loss might be as tremendous as 50 pounds in one month. If you’re overweight, you can expect to lose 5-10% of your body weight in a month following Dr. Now’s diet.

Summing up

Dr. Nowzaradan’s diet is very specific, and it’s not for everyone. It is severely restrictive and should be used only if the health risks of staying obese are higher than the health risks of the diet itself.

The diet’s macronutrient and food group composition is very effective and might be considered by people who try to boost their weight loss. 

  • The high percentage of protein in the diet provides higher satiety levels(6). 
  • A large amount of non-starchy vegetables is a guarantee that an individual will have voluminous meals. 
  • Sugar, alcohol, and processed foods restriction will help to refrain from highly-palatable, calorie-dense food that one can easily overeat. 

This kind of restrictive diet might be necessary for those about to get fat loss surgery, but it is surely not the first option for those who just want to lose several pounds before the vacation.
