Philip has had his share of body shaming and received backlash in the 2000s due to poor eating habits. Years later, he decided to improve his health and fitness not just for his body but also for his golf career, which made him alter his diet. 

After shedding a few extra pounds, he feels light and healthier and has great energy levels. According to Sunaina Sindhwani, a clinical nutritionist and an internationally certified skin specialist, “Weight could be reduced naturally by limiting processed foods, adding protein with respect to your body weight, adding good fats,  incorporating physical activity in your regular routine, focusing more on whole foods and also by adding thermogenic foods to the diet.”

However, for Phil, it wasn't just intermittent fasting that helped him tone down. Scroll down to get the insights his Phil Mickelson's career highlights, diet, and fitness routine.

The pro-golfer Phil Mickelson suffers from psoriasis and psoriatic arthritis, a chronic inflammatory joint disease that is incurable. It is a chronic inflammatory joint disease with symptoms like inflammatory changes in attachments of articular capsules, tendons, and ligaments to the bone surface. There are also times when destructive changes in bones usually appear after a few months, due to which the disease flares or little pain or disability is experienced (3).

In addition, one is more likely to suffer from obesity, cardiovascular disease, non-alcoholic fatty liver disease, diabetes, and metabolic syndrome (4). 

Moreover, Mickelson's weight loss was also driven by a desire to improve his health, including his ability to maintain swing speed and overall fitness for his golf career. He revealed in an interview that he still has to "hit the shots" and be fit for the sport, which is why he has "got to be in shape" so that he can have the speed that allows him to compete. In an interview, he jokingly mentioned that he "stopped eating food," which was a "big help" for him - this was in reference to his intermittent fasting.

Phil Mickelson’s Diet Plan


Phil Mickelson’s weight loss was a success due to his commitment to intermittent fasting due to which he not only lost fat but also muscles. This dieting regimen is more of little to no diet consumption. Rather than fasting just for a day, one does fasting for five to six days. In this case, you need to feed your body a liquid-based diet.

For Phil, water and his very own coffee helped. As per a study, intermittent fasting is an alternative and easily applicable dietary intervention for caloric restriction (5). 

Back in 2021, Phil revealed that coffee saved his career. Plus, he is extremely picky about his brew and hence, always carries a flask along.
