Weight Management & Ideal Protein Q & A



What is Ideal Protein?

The Ideal Protein Protocol is a ketogenic weight loss program consisting of four phases that help patients lose weight and keep it off. Developed by medical professionals, the Ideal Protein Protocol uses sound scientific evidence; in fact, Centra Internal Medicine now has a partnership with Ideal Protein, so you can be confident that it’s safe, healthy, and effective.

The Ideal Protein Protocol combines a nutritious, healthy diet with one-on-one coaching and education to help you live a healthier lifestyle, under the expert supervision of Dr. Sahni. Following the Ideal Protein plan doesn’t just help you lose weight; it gives you back your life, health, and vitality.

How does Ideal Protein work?

Ideal Protein uses ketogenic principles, which involve limiting carbohydrate intake to a minimum. Your body gets its energy from carbs, fat, and protein. It uses any available carbs first, which are all the sugars and starches in your diet, then takes energy from fat. Finally, if there’s no other energy source, your body turns to protein. 

By limiting carbohydrates, the Ideal Protein program encourages your body to start using your fat reserves for energy, resulting in healthy, sustainable weight loss. Also, eating high-quality proteins aids the development of muscle mass, and is far better for your body than consuming carbohydrates. Ideal Protein isn’t a high-protein diet but provides high-quality protein in a form that’s easy for you to eat.

The Ideal Protein plan provides you with a variety of delicious, nutritious meals, snacks, and treats, as well as complete meal replacements and gluten-free options. You combine these with fresh vegetables and whole proteins such as fish or meat, to give you all the nutrients you need and the right number of calories for the phase you’re on.

What are the four phases of the Ideal Protein Protocol?

The four phases represent the different stages on your route to a healthier, slimmer you:

Phase one

Phase one is weight loss, which you follow until you reach your target weight.

Phase two 

You follow phase two for two weeks once you reach your ideal weight.

Phase three

This is the pre-stabilization phase that prepares you for a lifetime of healthy eating and vitality.

Phase four

This is the maintenance phase, or lifestyle living phase, where you spend 12 months reinforcing your healthier relationship with food. 

Throughout the whole process, you receive support from Dr. Sahni to help you maintain your new, healthy weight.

How do I know if I need help with weight management?

Each time you visit Centra Internal Medicine, a member of the team weighs you. If you’re over the healthy weight range for your age and height, Dr. Sahni can give you the guidance you need to keep your weight under control.


Your weight is categorized by your body mass index (BMI), a number calculated using your height and weight. The BMI classifications are:

  • Underweight: Under 18.5
  • Normal weight: 18.5 - 24.9
  • Overweight: 25.0 - 29.9
  • Obesity: 30.0 or above

It’s important to note that the current BMI system doesn’t differentiate between weight from muscle and fat. Some patients with high BMI are simply very muscular, but not obese. Because of this, only your doctor can determine if you need to lose weight.

It’s also perfectly healthy for your weight to fluctuate a bit. If you’re consistently gaining weight or losing weight and are having trouble stopping it, you could benefit from a weight management plan.

How can I manage my weight?

Most people recognize that eating a sufficient, healthy diet and getting exercise are important parts of controlling their weight. However, even if you feel like you’re doing everything correctly, you may need some help or motivation to truly change your habits.

As part of your personalized weight management plan, Dr. Sahni provides:

  • Specific healthy changes to your diet
  • Guidance for physical activity within your ability
  • Medications for weight loss when necessary
  • Reasonable goals for you to work toward


Your weight may be due to genetics, overeating, a lack of physical activity, stress, or a combination of several factors. While creating your plan, Dr. Sahni takes these into account to change your lifestyle in a way that works.

What happens if I don’t manage my weight?

Being outside of a healthy weight range can take a toll on your health if you don’t change your lifestyle. Obesity puts you at a higher risk for:

  • High blood pressure
  • Diabetes
  • High cholesterol
  • Heart problems
  • Sleep apnea
  • Stress on your bones and joints
  • Some cancers

Being overweight or obese can also decrease your mobility. Further, you get fatigued quickly, making it difficult to accomplish all of the things you’d like to get done in a day.

After assessing you and your health, Dr. Sahni gives you a list of specific ways that your weight is affecting your well-being.

If you’re struggling to lose weight, even if you feel like you’re doing everything right, call or book an appointment online at Centra Internal Medicine for guidance and motivation for weight management.
