The Jumpstart diet program has garnered attention as a weight loss solution, with various approaches and programs available. This article delves into the Jumpstart diet, examining its principles, effectiveness, and different variations, providing a comprehensive overview for those considering this weight loss approach.
Understanding the Jumpstart Diet
The Jumpstart diet is designed to initiate rapid weight loss and encourage healthy habits. It often involves a combination of dietary changes, supplementation, and lifestyle adjustments. The goal is to "jumpstart" the body into a state of weight loss, which can then be sustained through continued healthy practices.
Bob Harper's "Jumpstart to Skinny": A 40/40/20 Approach
Bob Harper, the author of "Jumpstart to Skinny," advocates a specific nutritional architecture based on a 40/40/20 plan. This plan focuses on the balance of macronutrients: protein, carbohydrates, and fats.
The Macronutrient Primer
- Protein (40%): Harper emphasizes protein as essential for maintaining muscle mass during weight loss and controlling hunger by stabilizing blood sugar and insulin levels.
- Carbohydrates (40%): Carbohydrates are considered the body's primary fuel source. Harper distinguishes between simple carbohydrates (found in fruits and vegetables) and complex carbohydrates (found in processed, starchy foods). The diet prioritizes simple carbohydrates while limiting complex ones. He also introduces the concept of "net carbs," which is the total carbohydrate content of a food minus its fiber content.
- Fats (20%): Healthy fats are included to maintain cell structure, skin elasticity, and provide a dense source of fuel.
In "The Jumpstart Day-by-Day Regimen," Harper provides daily menus designed to closely match the 40/40/20 macronutrient distribution. He also allows for unlimited quantities of "Jumpstart veggies" as free calories, ensuring adequate fiber intake.
Calorie Restriction: A Key Component
Harper is forthright about calorie restriction, recommending 800 calories per day for women and 1,200 for men. He acknowledges the difficulty of this restriction but emphasizes its necessity for achieving rapid weight loss. He also notes that the quality of calories is as important as the quantity, highlighting the importance of specific food choices.

Harper addresses the concern of weight regain after a very low-calorie diet (VLCD). He cites research suggesting that VLCDs can lead to positive metabolic changes that reduce the likelihood of weight regain, particularly when combined with active follow-up treatment.
JumpstartMD: A Medically Supervised Program
JumpstartMD is a commercial weight loss program that emphasizes a low-to-very-low-carbohydrate, real-food diet, along with personalized support and medical supervision.
Key Features of JumpstartMD
- Low-Carbohydrate Diet: The program focuses on reducing carbohydrate intake, typically to under 50 grams per day, from low-glycemic vegetables and fruits.
- Personalized Support: Participants receive one-on-one support from trained health counselors in a medical clinic setting.
- Medical Supervision: Licensed healthcare practitioners are present in every center, allowing for adjustments to medications and the option of FDA-approved weight loss medications for eligible patients.
- Real Food Emphasis: JumpstartMD promotes the consumption of fresh, whole, non-packaged foods, avoiding prepackaged meals or meal replacements.
JumpstartMD Outcomes
A study presented at Obesity Week 2018 showcased JumpstartMD's weight loss outcomes compared to other commercial programs. The study, which reviewed data from 22,407 patients between 2007 and 2017, found that patients who attended at least 75% of their weekly appointments experienced significant weight loss:
- Average of 21 pounds at three months
- 30 pounds at six months
- 35 pounds at nine months
These patients also experienced reductions in body weight and BMI. The study also found that JumpstartMD patients experienced more weight loss at three and six months compared to Weight Watchers, Jenny Craig, and Nutrisystem.
The program's approach to weight management uses a real-food low-to-very-low-carbohydrate diet and one-on-one, personalized instruction and support from trained health counselors in the setting of a medical clinic. It is an alternative to other commercial calorie-counting and meal plan programs that use group education and group support.

Macronutrient Tracking and Monitoring
Participants are given a macronutrient tracking tool to record their daily consumption of carbohydrate, protein, and healthy fat servings. They review their progress in achieving their macronutrient recommendations with their individual JumpstartMD clinician or health coach via weekly one-on-one in person visits.
Statistical Analysis
Anonymized data were provided to an independent statistician not previously associated with the commercial program for analysis. Attendance was calculated at each visit as the ratio of the number of follow-up appointments attended divided by the expected number of weekly appointments. For each individual, average number of days since baseline, weight loss, % weight loss, BMI change, attendance, and ≥5% and ≥10% weight loss were calculated within each two-week interval since baseline. Mean changes from baseline ± SE were calculated over all subjects within each interval and plotted vs. the average follow-up duration. Regression analyses were used to assess the relationship between weight loss vs. attendance, baseline BMI, sex, and age. Analysis of covariance was used to assess weight loss differences between patients on and off obesity drugs, with and without adjustment for enrollment duration.
JumpstartMD weight losses were compared to those reported for other commercial programs (Weight Watchers, Slimming World, Rosemary Conley, Biggest Losers Club, eDiet, Jenny Craig, Itrim, Nutrisystem, Medifast, Health Management Resources, Metabolic Balance Nutrition Program, and Diet Chef) when matched for follow-up duration, BMI eligibility, age, proportion of males, and sex-specific baseline BMI effects.
The primary outcome for comparing JumpstartMD to other commercial programs was LOCF because it encapsulates both retention and weight loss success. Differences in design and analyses have stymied prior efforts to synthesize commercial weight loss results by meta-analyses. These analyses adjust for these differences by tailoring the JumpstartMD sample to the recruitment specifications and follow-up duration of each published report.
Customer Reviews and Experiences
Customer reviews of JumpstartMD are mixed, with many praising the program's effectiveness and the support provided by staff. Some reviewers highlight the positive impact of the program on their overall health and well-being, with improvements in blood pressure, blood tests, and other health markers. Some reviewers mention specific staff members who were particularly helpful and supportive, such as Tamar, Jonica, Chris, Cassandra, Josh, and Summer.

However, some negative reviews mention issues such as misleading sales tactics, upselling, billing errors, and concerns about the handling of medications. One reviewer reported that a compound medication came late with cold packs that were hot, and Tirzepatide was expired. It's important to consider these mixed experiences when evaluating the program.
The 24-Day JumpStart by AdvoCare
The 24-Day JumpStart by AdvoCare is another program designed to kickstart healthy habits. It emphasizes a healthy diet, supplementation, stress and sleep management, and exercise. The program includes products and guidance to support these areas.
A Simple Diet Approach
The diet involves consuming five shakes a day, totaling approximately 1000 calories, 145 grams of protein, and a low carbohydrate intake. The shakes, such as Weight & Inches shakes, are designed to be filling and can be mixed with water or ice.
The program recommends taking multivitamins and essential fatty acids to ensure adequate nutrient intake. Modifications can be made, such as incorporating a healthy meal alongside the shakes or using alternative products with different macronutrient ratios.
Expected Weight Loss
The program claims that people lose between 5-25 pounds during this 2 week Jump Start Diet.
Benefits of a Whole-Food, Plant-Based Jumpstart Program
Some Jumpstart programs are based on a whole-food, plant-based (WFPB) diet, which excludes animal products and processed foods. These programs often focus on education, skill-building, and community support to promote long-term adherence and health improvements.
Program Structure
These programs typically involve a series of sessions, including:
- Group Breakfasts and Lunches: Participants share WFPB meals together.
- Small Group Activities: Participants engage in discussions and activities related to the diet.
- Cooking Demonstrations: Participants learn how to prepare WFPB meals.
- Medical Provider Review: Participants have their progress reviewed by a medical provider.
Positive Health Outcomes
Studies of WFPB Jumpstart programs have shown improvements in various health markers, including:
- Weight loss
- Blood sugar levels
- Blood pressure
- Cholesterol levels
- Quality of life
Participants also report improvements in energy, mood, pain, and sleep.
Limitations
These programs typically require a significant time commitment from participants, which may limit their accessibility.
