Jorge Cruise (born March 6, 1971, in Mexico City) is a Mexican author, fitness trainer and proponent of intermittent fasting and low-carbohydrate dieting.

Several years later, he got his big break when Oprah Winfrey both hired him as her personal trainer and featured him on her televised show and in her magazine.

[1][2] Cruise has created a number of different diet plans over the last decade, his philosophy evolving over the years from heavy emphasis on increasing metabolism through building lean muscle (8 Minutes in the Morning, The 12-Second Sequence) to advocating smaller-yet-more-frequent meals (The 3-Hour Diet, Body at Home) to recommending low-carb/low-sugar meal plans (The Belly Fat Cure).

[4] It was criticized by Rebecca Foster of the British Nutrition Foundation who noted that eating meals every three hours would increase over-eating and cause negative effects on dental health.

[4] Cruise has authored The 100 diet in 2013, which restricts the consumption of sugar calories to 100 per day for quick weight loss.
