I have done the low carb. A lot of work. Reading labels and cooking for low carb is hard. I also felt deprived. No sweets. Never any bread or potatoes. I have been doing the one meal a day and am losing weight. Its easier for me. Because I can eat what I want. I even have an ice cream cone after dinner. If I get really hungry during the day Ill have 3 baby carrots. The 1 meal a day is much easier to me.
Good luck!
My daughter did it back in her teens, lost 40+ pounds, and never put it back on.
Low carb - no fat diets do not work. I saw a study on that a couple years ago.
