Who Should Avoid Weight Loss Programs?
Dieting programs are not for everyone, especially those at risk of developing eating disorders. Individuals in these situations should work with a registered dietitian for individualized advice.
Alternative Healthy Diets for Weight Loss
- The Mediterranean Diet: Emphasizes fresh, plant-based food, whole grains, nuts, beans, lean poultry, seafood, olive oil, herbs, and spices.

- A Plant-Based Diet: Includes vegan, vegetarian, pescatarian, Mediterranean, and flexitarian diets.
OPTIFAST Program (OP)
The OPTIFAST program (OP) is one example of a TMR weight‐loss intervention. Originally developed in the 1970s as a VLCD providing 420 kcal/d, the program has evolved to include comprehensive behavioral intervention and a higher calorie intake.
OPTIWIN Trial: Comparing OPTIFAST to a Food-Based (FB) Diet
The OPTIWIN trial was designed to test the effectiveness of OP. The goal was to determine whether OP was more effective than an FB dietary plan and comprehensive behavioral intervention for weight loss at 26 and 52 weeks.
Study Design and Participants
- Participants: Individuals with a BMI of 30 to 55 kg/m2, aged 18 to 70 years old, and nonsmokers.
- Randomization: Participants were randomized to either the OPTIFAST (OP) or food-based (FB) dietary and lifestyle interventions for 26 weeks, followed by a weight-maintenance phase.
- OP Intervention: Participants were provided with meal replacements (MR) at no cost. Those with BMI < 45 were instructed to use five MRs per day (800 kcal total), while those with higher BMIs received six MRs per day (960 kcal) or six MRs plus one meal daily (1,100-1,200 kcal).
- FB Intervention: Participants followed a calorie-restricted diet emphasizing lower fat intake (25%-30% of total calories) and received gift cards totaling $800 to offset the cost of groceries.
- Behavioral Sessions: Both treatment groups had weekly group behavioral sessions for the duration of the intervention.
- Medical Monitoring: OP participants saw a clinician regularly for medical monitoring, while FB participants had fewer medical monitoring and counseling visits.
Key Findings
- Weight Loss: At 26 weeks, the OP group experienced a 12.4% ± 0.6% weight loss compared to 6.0% ± 0.6% in the FB group (P < 0.001). At 52 weeks, the OP group had a 10.5% ± 0.6% weight loss versus 5.5% ± 0.6% in the FB group (P < 0.001).
- Body Composition: Fat mass loss was greater for the OP group, while lean mass loss was proportional to total weight loss in both groups.
- Adverse Events (AEs): Mild or moderate AEs were reported by 76.8% of OP and 62.7% of FB participants. Serious AEs were reported by 4.5% of OP and 3.3% of FB participants.
- Discontinuation Rates: Discontinuation rates were not statistically different between groups (29.3% OP; 31.9% FB; P = 0.60).
Conclusions from OPTIWIN
The OPTIWIN trial demonstrated that the OPTIFAST program (OP) was more effective than a food-based (FB) dietary plan for weight loss at both 26 and 52 weeks. Participants in the OP treatment arm lost a significantly greater percentage of their initial weight and experienced greater losses of fat mass. The OP program was well-tolerated and safe.
The Role of Meal Replacements
Meal replacements (MR), typically formulated as prepackaged shakes or bars, are another option for reducing energy intake. They help promote weight loss by eliminating choices, controlling portions, and providing satiation at lower calorie intakes. Total meal replacement (TMR), or the use of MR as the sole source of daily nutrition, has been studied as one option to enhance behavioral weight loss.
General Recommendations for Safe Weight Loss
Losing 1 to 2 pounds per week (or up to 8 pounds per month) is generally considered safe. Rapid weight loss can lead to nutritional deficiencies, muscle loss, and other health issues.
