More of a diet support book than an actual diet guide, Neris and India piece together ideas from other diets (e.g. Atkins Diet) offering food plans and daily recipes to help dieters get through the early days. Written in the style of friends talking to other friends, the authors mention unpleasant dieting details such as difficulty finding clothes (and underclothes) that fit, problems with constipation, advice on saggy skin, and unflattering "before" photographs. They also include personal goals, diet histories, diary entries, and hair and makeup tips.

Their intended audience is obviously women, but not all women will be able to relate to their advice. For example, women with only 10-25 pounds to lose, vegetarians, and vegans may find the diet restrictions drastic and unsatisfactory. Readers who will benefit the most from Neris and India’s Idiot-Proof Diet are women who are extremely overweight, have no dieting strategy currently in place, get little or no exercise, and absolutely love meat, eggs, and cheese. In their funny, friendly tone, both authors claim to have gone from size twenty-two down to size twelve during the course of a year. If readers are able to adhere to their strict low-carb plan, they may achieve comparable results.
