Dr. McDougall (promoets a high starch vegan diet) actually centers his diet around starches (potatoes, rice etc.) and recommends against any added fat and keeping fat intake below 20% of your total calories (studies showing fat is easily stored as fat, whereas the body does not store carbohydrates as well and normally raise metabolism and burns them instead.) His program has a very effective and stable weight loss record.
Again there are many studies showing starches lead to increased metabolisms (body does not store carbohydrates as it digest them as well as it does fat, so instead it just burns them - i.e. increased metabolism.) His newsletter has highlighted many of those studies.

High Carbohydrate* Diet Causes Effortless Weight Loss
Effects of an Ad Libitum (without restriction on amount) Low-Fat, High-Carbohydrate Diet on Body Weight, Body Composition, and Fat Distribution in Older Men and Women: A Randomized Controlled Trial by Nicholas P. Hays in the January 26, 2004 issue of the Archives of Internal Medicine found when older men and women consumed as much as they wanted of high-carbohydrate, low-fat foods they lost weight without “dieting.” Over 12-weeks, participants on the recommended diet lost about 7 pounds without cutting calories and without exercising – and almost 11 pounds with 45 minutes of stationary bike-riding, four times weekly. The control group lost no weight. The experimental diet was 63% carbohydrate and 18% fat – the McDougall diet is even more effective because it is 80% carbohydrate and 7% fat.
This article is an excellent review of the principles discussed in my book, the McDougall Program for Maximum Weight Loss, first published in 1994 (just to point out, not much has happened in 10 years for better nutrition). The authors provide many recent scientific references establishing why a high carbohydrate diet effortlessly and effectively results in weight loss without hunger in overweight people, and provides a lifetime of trim body weight maintenance.
The scientific explanations for why a diet of starches, vegetables and fruits is the real solution for obesity in the Western world are found in this article. These are the three main principles:
1) High carbohydrate foods are very low in calorie density – very bulky, so they fill the stomach with fewer calories than the Western (American) diet.
2) The fat you eat is the fat you wear – fat is effortlessly stored – excess carbohydrates are not turned into fat under normal living conditions – excess carbohydrate is simply burned off.
3) Carbohydrates satisfy your hunger drive – fats leave you unsatisfied and looking for food (carbohydrate). You act like an “Obsessive Compulsive Overeater” – like you have some kind of emotional-mental disorder, and all you really are is hungry for carbohydrates.
