Common mistake about fruits. Sugar IS a carbohydrate. That's why you can't look at 'carbs' so simply; and why people get so fat off fruit juice. There are many types of carbs. Everything from slow releasing, to ultra fast metabolising. I.e. Rice is actually a pretty good dinner food, because it metabolises so quickly, as opposed to pasta, which stores for a much slower release. I'm sure you've noticed you'll be out eating chinese or thai and be eating a lot, but you seem to constantly have room? Then there is the quality of the carbs, e.g. brown vs white. White bread contains a lot of sugar and empty carbs and therefore isn't as nutritious as brown, which also has more fiber. It's very simplistic to define foods as 'fat, carbs & protein'. In regards to potatoes, they aren't a high carb food (15g of starch per 100g compared to 50+ per 100 for pasta). They are mostly watery starch (which is the real carb) with medium carb amounts, so they are actually a pretty good dinner food becuase of how much water (and therefore water weight "pseudo space" they assume in the stomach), not to mention the veggie goodness. You have the right idea with reducing carbs at dinnertime, obviously avoiding the possibility of storage. Storage isn't always a bad thing however. If you plan to exercise in the morning, pasta is a great meal to have in the evening, just ask any cyclist. Don't forget though, that if you are doing weights to improve muscle mass etc, your metabolism doesn't just "shut off" after bedtime. If you've been pumping the iron that day, your body will be working pretty hard still, even while you're asleep. I'm still a massive advocate of the balanced meal idea. It's designed to hit the body in 3 or more meals a day exactly where it needs it. I find that a lot of people opt for meal size alteration. They will have the biggest 'balanced' meal at breakfest (therefore telling the metabolism to get the fuck started, and expect this sort of meal again soon), then drop the meal size slightly leaving the metabolism not quite full, but expecting to be replenished, then making dinner the smallest meal of the night, while all the time the metabolism has been burning energy like a mother, and now it's wondering where it's fill is? And therefore using the little resources it has left to burn off during the night to start again. I haven't actually found that what or how much i eat affects my weight... it seems to just reflect more in my moods and energy levels. This idea makes more sense to me than food group exclusion. To be honest though, i am not shutting down your plan in the slightest. One of the reasons being a dietician is so hard for... well dieticians is because it is ALL trial and error until they can work out how your body will react to food groups etc and what will do what. An obvious example being that if you are Irish in origin, you could probably eat potatoes until the cows came home (and drink whisky), whereas this same diet might make an Indian fat, whereas their diet consists of high amounts of coconut milk etc (which is pure saturated fat), but this doesn't make them fat. Clearly ancestral bodies evolve to metabolise the particular available foods from the various regions, whether they be complex fats or simple sugars, and this still trickles down through us today. So if it works for you, then it works for you. It's very hard to recommend exactly what guidelines to follow.
