at least two people have done this and documented it
example:
"Ms. Whaley, true to her plan, kept her calories low -- on average she consumed 1809 calories per day -- resulting in a weight loss of ten pounds over the course of 30 days. To maintain her starting weight, she would have had to consume about 2000-2200 calories per day. Her nutrient intake was higher in fat than is usually recommended -- about 39% of her calories came from fat (recommended range is 20-35%). Her saturated fat intake was also a bit high -- 13% rather than the recommended 10%. She consumed about 46% of her calories from carbohydrates -- the lower edge of what the guidelines suggest. Her protein intake was about 16% of calories, which is in the suggested range for adults her age. Ms. Whaley's average cholesterol intake was somewhat over the upper limit -- 338 milligrams instead of 300 or less. Her consumption of dietary fiber was, however, only about 8 grams per day -- less than one-third of the recommended 25 grams."
She did better on meeting recommendations for a number of vitamins and minerals, however. Her intake of vitamins A, B6, B12, C, niacin, and riboflavin all exceeded 100 percent of the recommended amounts. She did fall a little short with respect to thiamin (87% of suggested amount). An important deficit was the B vitamin folic acid: Ms. Whaley only consumed about 50% of the recommended 400 micrograms/day.
The adequacy of Ms. Whaley's mineral consumption varied. Her intake of calcium, important for bone strength, was 96% of the recommended 1000 milligrams -- better than that most American women. But her intake of several other minerals -- iodine, magnesium, potassium, selenium and zinc, was less than optimal -- anywhere from 15 to 60 percent of recommended values. Her iron intake, too, was low -- only 49% of the current RDA. Ms. Whaley's sodium intake was about twice the recommended level -- 213% to be exact."

morgan spurlock manipulated his 30 days experiment to get the desired results, he maxed out his caloric intake, set up a rule he HAD to supersize if it was offered and completely stopped exercising
