Rosemary Conley's "Eat Yourself Slim," a combination diet and low-fat cookbook, may be difficult to find in print in the U.S., but an electronic version is readily available. If you're willing to pay international shipping, you can also purchase the book directly through the U.K. author's website.
The effort might be worth it: You receive a personal calorie allowance based on your height, weight and how much weight you want to lose. The plan encourages eating regular meals (no skipping breakfast), and giving up foods like cheese that have more than 4 percent fat. (One subject of the U.K.'s reality show/scientific study, the "Diet Trials," followed the "Eat Yourself Slim" diet and said giving up cheese was one of her biggest challenges.) However, you're allowed one high-fat treat per day. Group exercise classes are part of the regimen; one expert says those who like exercising in groups may enjoy this component, but others probably won't.
Although you won't find many online reviews of this book -- which was originally published in the late 1980s -- those who followed the diet in "Diet Trials" are one of only two groups to report continued success after the study ended. In a separate study, "Eat Yourself Slim" was also shown to improve subjects' LDL (bad) cholesterol levels. The author has produced a number of other diet books and cookbooks, and offers online support for several diets through her website.
Clinical trials of Rosemary Conley's "Eat Yourself Slim" are published in Public Health Nutrition and the British Medical Journal. A "Diet Trials" participant who followed the diet shares her impressions in an article for the Daily Mail, and the BBC offers additional information about each of the weight-loss plans featured in "Diet Trials."
1. Public Health Nutrition
Researchers track 300 overweight or obese individuals for six months as each uses one of four commercial diets. Although there's no significant difference in weight lost between the various diets, "Eat Yourself Slim" lowers subjects' LDL or "bad" cholesterol.

2. British Medical Journal
The "Diet Trials," a British medical study that was also chronicled as reality TV, follows nearly 300 dieters as they participate in one of four commercially available diets or a self-regulated control group. All dieters report similar weight loss after about six months, regardless of diet, but "Eat Yourself Slim" participants are one of only two groups to report continued success after the study.

4. Daily Mail (United Kingdom)
Two participants from "Diet Trials" share their personal experiences, one with Slim-Fast and the other with Rosemary Conley's "Eat Yourself Slim." The latter had a daily calorie allowance and was encouraged to eat regular meals of anything she wanted, as long as it contained less than 4 percent fat.
