What You'll Learn
Oprah's Optifast liquid diet
Oprah Winfrey has been considered a role model for many young women, especially when it comes to body image and confidence. She has been applauded for speaking openly about her relationship with food and her changing body. However, she has also been criticised for promoting diets that have been slammed as faddy and potentially dangerous.
In 1988, Oprah revealed on her television talk show that she had lost 67 pounds since July by following a liquid protein diet program called Optifast. On this diet, she consumed 800 calories per day in the form of four liquid shakes, with no solid food. This resulted in a significant weight loss for Oprah, but she later reflected that the results were fleeting. After returning to solid food, she quickly regained weight and realised that her metabolism had been negatively impacted.
Optifast is a medically supervised weight-loss program that aims to help individuals lose weight rapidly while preserving lean muscle tissue. The program is typically recommended for those who need to lose 50 or more pounds or who are 30% or more above their desirable body weight. It involves a 400-calorie liquid diet that is limited to 12 weeks, followed by a gradual reintroduction of regular foods over the next 14 weeks. Throughout the program, patients are medically monitored and receive support from fellow dieters and professionals, including a supervising physician, a behaviour therapist, a nutritionist, and an exercise physiologist.
While Optifast can be effective for weight loss, there are concerns about the potential health risks associated with liquid diets. Doctors generally only recommend liquid diets for specific medical reasons, such as preparing for surgery or undergoing medical weight loss treatment. Liquid diets can be challenging to get all the necessary calories and nutrients, and they may disrupt metabolic rates, making them unsustainable in the long term.

Oprah's weight loss and gain
Oprah Winfrey has been in the spotlight for her weight loss journey for decades. In 1988, she revealed on her television talk show that she had lost 67 pounds since July by following a liquid protein diet program called Optifast. This diet consisted of drinking 800 calories per day in the form of four liquid shakes, with minimal nutritional value. While this led to rapid weight loss, it was not sustainable, and Oprah quickly regained the weight once she returned to eating solid foods. She reflected on this experience as one of her biggest regrets, acknowledging that it promoted an unhealthy and unsustainable approach to weight loss.
Oprah has been open about her struggles with weight loss and her changing body image over the years. Her weight has fluctuated between 160 and 230 pounds, and she has tried various diets and approaches to manage her weight. In 1977, she consulted a diet doctor who put her on a restrictive 1,200-calorie diet, which led to short-term weight loss followed by rapid weight gain. Oprah has also been criticised for promoting fad diets, such as the Cabbage Soup diet, through her TV shows and magazine.
In recent years, Oprah has taken a more holistic approach to weight management, combining healthy lifestyle choices with medical interventions. She has been transparent about her use of weight-loss medications, such as Ozempic and Trulicity, which are GLP-1 agonists that regulate appetite and help people feel full. She emphasised that these medications are not a "magic bullet" but rather a tool to support her overall health and fitness routine. In addition to medication, Oprah has incorporated regular exercise, mindful food choices, and habit-tracking apps into her weight loss journey.
Oprah's most recent weight loss transformation in 2025 has inspired millions. Through a balanced approach that included medication, clean eating, and regular movement, she lost over 40 pounds in under a year. She emphasised that this journey was about reclaiming power over her health and breaking free from the constraints of "diet culture". Oprah's story has resonated with many, especially women over 40, as it showcases a relatable and sustainable approach to weight loss and improved health.

Oprah's diet regrets
Oprah Winfrey has been open about her weight loss journey and her changing body image over the years. In 1988, she revealed on her self-titled talk show that she had lost 67 pounds since July by following a liquid protein diet program called Optifast. This involved consuming nothing but Optifast shakes (a protein powder mixed with water) five times a day, totalling about 800 calories.
While this extreme measure led to significant weight loss, Oprah has since expressed regret for promoting dangerous diet culture. She has acknowledged that her highly publicised weight loss methods, such as the liquid diet and the infamous "wagon of fat" moment on her show, sent the wrong message to her audience. She reflected that starving herself for months was not sustainable and had negative consequences for her metabolism, leading to a cycle of weight gain and loss.
Oprah's honesty about her struggles with weight loss has been met with both praise and criticism. She has been applauded for speaking out against the toxic diet culture that she once contributed to. However, some have questioned her promotion of weight loss drugs and her involvement with Weight Watchers. Despite this, Oprah continues to emphasise the importance of individual choice and making healthy lifestyle changes, whether that includes medication or not.
In addition to liquid diets and weight loss drugs, Oprah has tried various methods to manage her weight. She has attempted calorie restriction, a vegan cleanse, and hiring a personal chef to cook low-fat and low-calorie meals. She has also been a spokesperson for Weight Watchers, undergone a medically supervised weight loss program, and tried rigorous exercise regimens.

Oprah's weight loss medication
Oprah Winfrey has had a long and public battle with weight loss. In 1988, she went on a liquid protein diet called Optifast, which helped her lose 67 pounds. However, she later regretted this extreme diet, which saw her "not eat a single morsel of food" and survive on 800 calories a day in the form of liquid shakes.
In 2023, Oprah revealed that she had turned to weight-loss medication to help manage her weight. She told People magazine that she had reconciled the science and consulted her doctor, who prescribed her a weight-loss drug. She did not name the medication but said that it helped her manage her weight and stop "yo-yoing". She also said that she no longer felt ashamed about taking medication to help her lose weight.
In a 2025 interview, Oprah revealed that the medication she took was a GLP-1 agonist, a class of weight-loss medications that work by mimicking the hormone GLP-1, which the body releases after eating, helping people feel full and slowing stomach emptying. Some brand names of GLP-1s include Ozempic, Trulicity, Wegovy, and Mounjaro.
Oprah has been applauded for speaking openly about her relationship with food and her changing body. She has also been praised for her honesty and for lending her influence to weight-loss drugs, helping to remove the stigma around taking medication to manage weight.

Oprah's weight loss journey
Oprah Winfrey has been candid about her weight loss journey, which has fluctuated throughout her time in the spotlight. In 1988, she revealed on her talk show that she had lost 67 pounds since July by following a liquid protein diet program called Optifast. This involved consuming nothing but Optifast shakes, a mix of protein powder and water, five times a day. She described this as the most difficult thing she had ever done and expressed regret for promoting an unhealthy message about weight loss.
Optifast is a medically supervised weight-loss program that restricts patients to an 800-calorie liquid diet for 12 weeks, followed by a gradual reintroduction to regular food. While it can be effective for rapid weight loss, experts warn that it may not be sustainable, and that underlying behavioural issues must be addressed to maintain results. Oprah herself regained weight after coming off the diet, as her metabolism had slowed down.
In addition to Optifast, Oprah has tried various other diets and weight-loss methods over the years. She has been open about her struggles with compulsive eating and her desire to be thin. She has also promoted diets and products, such as Weight Watchers, for which she served as a spokesperson, and a 21-day vegan cleanse in 2011.
More recently, in 2025, Oprah revealed that she had been taking weight-loss medication, specifically a GLP-1 agonist, to manage her weight. She emphasised that this was just one part of her regimen, which also included a healthy diet and exercise. She has also spoken out against diet culture, apologising for her role in promoting unhealthy weight-loss methods and encouraging body acceptance.
