Dr. Nowzaradan — more commonly known as Dr. Now — is the direct, brutally honest weight loss surgeon on the popular TLC show, “My 600-lb Life.”
If you’re a fan of the show like me, you know that Dr. Now prescribes a 1,000–1,200 calorie diet plan — referred to as the Dr. Now diet — for his patients before performing weight loss surgery.
The diet is intended to help patients lose weight fast and shrink their liver so they can qualify for weight loss surgery, and also prove to Dr. Now that they can develop healthy habits to maintain the weight loss long-term.
However, if you’re looking to lose weight, you may wonder whether the diet can work for you.
This article explains whether the Dr. Now diet is safe and effective for fat loss and provides a sample 3-day Dr. Now diet plan.
What is the Dr. Now diet?
The Dr. Now diet is a low-calorie, high-protein diet.
The diet limits calories to 1,000–1,200 per day but in some instances, Dr. Now prescribes a medically-supervised 800-calorie diet.
The diet is similar to the diet Dr. Procter prescribes to his patients on several popular TLC shows, including, “1000-lb Best Friends”, “Too Large,” and for two seasons, “1000-lb Sisters.”
For reference, a 2,000-calorie diet is considered adequate to meet most people’s calorie and nutrient needs.
The 1,000-1,200 calories are split evenly across three meals and one small bedtime protein snack.
Each meal contains 20–25 grams of protein, representing about 30% of the total calories allowed.
The rest of the calories come mainly from vegetables — both starchy and non-starchy — and a small amount of fat.
The diet also requires that you drink at least six, 8-ounce cups of water daily.
Sugar-free drinks like Crystal Light, Zero Sugar Kool-Aid, flavored water, or unsweetened, decaf tea and coffee count towards this daily water goal.
Foods to eat and avoid on the diet
The Dr. Now diet emphasizes foods that are low in calories but high in protein and fiber.

- Non-starchy vegetables: asparagus, broccoli, brussels sprouts, cabbage, carrots, cauliflower, kale, lettuce, spinach, squash, zucchini

3-day sample Dr. Now diet meal plan
Portions sizes are important to keep under the 1,200 calorie limit.
For each meal, the diet generally includes:
- 2–3 ounces of protein
- 1/2 cup of starchy vegetables
- 1/2 cup of nonstarchy vegetables
- 1 serving of fat (5 grams)
Extra protein is also allowed for breakfast in the form of skim milk, and 1 ounce of protein is allowed for a nighttime snack.
For proteins, stick with dry heat cooking methods like broiling, grilling, or baking.

The main benefit of the Dr. Now diet is that it’s very effective for fast weight loss.
However, there isn’t anything special about the diet for weight loss perse, other than it’s low in calories.
Keep in mind that weight loss only occurs when you consume fewer calories than you need to support normal bodily functions and any physical activity.
The greater the calorie deficit, the more weight you will lose over a shorter period.
The patients to whom Dr. Now prescribes his diet plan may need anywhere from 3,000 to 4,000 calories per day just to maintain their weight.
As you can imagine, putting the patients on a 1,000-1,200 calorie diet will result in rapid weight loss due to the large calorie deficit.
But even if the number of calories you need to maintain your weight is not as high as the patients on “My 600-lb. Life,” the 1,000-1,200 calories that the diet allows is well below most people’s calorie needs.
While effective for rapid weight loss, the diet has several downsides.
The main disadvantage is that it can be difficult to follow long-term due to the diet’s rigidity and potential side effects.
So even though the diet is effective for weight loss, if you can’t follow the diet for very long, it’s useless.
Common side effects associated with a low-calorie diet like Dr. Now’s include:
- constant hunger
- low energy
- low sex drive
- poor sleep quality
- hair thinning
- cold intolerance
Although these side effects are minor, they can significantly interfere with your work or school performance as well as your relationships with family and friends.
The diet is also likely lacking in certain vitamins and minerals, like magnesium, vitamin D, calcium, thiamin, and potassium (2).
While short-term nutrient shortfalls are unlikely to pose any immediate health risks, following the diet for several weeks to months could lead to health problems.
The bottom line
The Dr. Nowzaradan diet, or Dr. Now diet, is a 1,000-1,200 calorie diet designed to promote rapid weight loss in patients before undergoing weight loss surgery.
While effective for weight loss, the diet can be extremely difficult to follow long-term due to its rigidity and potential side effects like low energy, poor sex drive, and irritability.
A better alternative to weight loss is to gradually develop healthy lifestyle behaviors that you can maintain long-term, such as increasing your intake of fruits and vegetables, prioritizing sleep, and staying physically active.
