The Rice Diet Solution is based on Duke University's medically supervised, live-in "Rice Diet Program," which is an intensive 2-4 week program for the treatment of obesity, diabetes, heart disease and kidney disease. Duke's program was originally developed in 1939, and its continued success (and prohibitive expense) inspired the the publication of "Rice Diet Solution" as a guide to the well-respected Duke program for dieters at home.
Be aware that the nutritional aspect of the Rice Diet is very restrictive. The food plan severely limits salt, sugar, fat and processed foods. If followed religiously - in conjuction with the recommended exercise - dieters are told they can expect to lose up to 20-30 pounds the first week, followed by 2.5-3.5 pounds per week in the later phases.
The plan is low-calorie, high-complex carbs, low-sodium, low-fat and low-sugar. "Ricers" is the slang term for people on the Rice Diet, and as the name suggests - they're eating a lot of rice. It's the staple of a limited menu of 30 items made up of lean protein, whole-grain starches, fruits, vegetables, beans and nonfat dairy. Salt - problematic for high blood pressure and kidney issues - is severly curtailed. The initial phase limits you to 800 calories per day, gradually increasing to the final, maintenance phase that permits a max 1,200 calories per day - for life. Note that Rice Diet recommends only 16 to 20 grams of protein daily - a great deal lower than the standard recommendation of 46 to 56 grams per day.
A couple of things: the original intent of severly restricting sodium in the plan was treatment of kidney disease and high blood pressure. Here, the sodium restriction triggers water loss. And therein lies your 20-30 pounds lost in the first week - it's water weight. Also, the extremely low recommendations for protein are problematic in that (a) protein helps you feel fuller, longer, and (b) under-consumption of protein can lead to loss of muscle-mass. And lastly, 1200 calories a day for the rest of your life is a very tough road to hoe.
The Rice Diet Solution includes recipes, weekly menus, advice on lifestyle changes and recommendations and guidance on nutrition, exercise and stress reduction techniques. No doubt this is a very comprehensive program, but it is tough. If you can stick with Rice Diet to its conclusion, you'll undoubtedly lose weight. The key is to figure out how to keep that weight off while living a more comfortable lifestyle going forward.
