Randy Jackson lost weight primarily through gastric bypass surgery in 2003, which helped him drop from around 350 pounds to about 230 pounds, a loss of over 100 pounds

. The surgery acted as a "jump starter" for rapid weight loss by reducing his stomach size to curb food intake

. However, maintaining the weight loss required significant lifestyle changes beyond surgery. Jackson focused on:

• Cleaning up his diet with an emphasis on healthy, balanced meals including fish, vegetables, rice or potatoes, and healthy snacks like fruits, cheese, and protein bars

• Practicing portion control and mindful eating to avoid emotional and binge eating, recognizing that "eating’s all emotional"

• Allowing himself small treats in moderation to prevent overindulgence later

• Incorporating daily Pilates and a balanced exercise regimen combining cardio and strength training to build muscle and boost metabolism

• Reducing processed foods, sugar, and unhealthy fats while prioritizing whole, nutrient-dense foods like lean proteins, healthy fats, and complex carbohydrates

His approach evolved into a holistic, sustainable lifestyle focusing on diet, exercise, and mental well-being, which helped him maintain his weight loss for two decades and feel healthier in his 60s

. In summary, Randy Jackson’s weight loss journey combined gastric bypass surgery with long-term commitment to healthy eating, mindful habits, and regular exercise to achieve and sustain his transformation
