I was fit-fat for years (My buddies called me the fastest fat guy they knew). I tried to restrict calories and expend more, and found myself in a complicated cycle of measuring, counting, analyzing, over-training and fighting cravings. It didn't work (especially long term). I wanted to try something else and did a ton of research and reading. Firstly I learned that there are BIG holes in the "science" behind nutrition and the nutritional studies on all sides of the debate (much of it relying on meta studies and correlations, not scientific experimentation) and cannot believe how far behind nutritional science is compared to other areas of scientific study. Through all of this I started my own self experiment on what I ate. What I eventually came to realize is, what I ate, had an enormous impact on me and fed back into my craving and hunger management responses and specifically the timing and content of the next meal. It also affected how I burned fuel during endurance exercise (I became more fat adapted fueling vs glycogen adapted fueling and could go farther and longer without the assistance of carbs, as my fat stores could keep up with my fueling requirements and didn't have to dip into the glycogen stores as much) and again this fed back into the timing and content of the next meal. These constant feedback loops managed my diet to match and my output energy without even trying. That did not happen on a high carb diet for me.
I eat things from the HFLCMP diet, do not have to measure count, weigh, or track calorie burn; have become naturally in tune with my body's physiological responses and hunger signals (something I found completely clouded and difficult to gauge on high carb diet), and don't have cravings or uncontrollable eating habits. I now just simply live, ride my bike and play outside a lot; eat (from my HFLCMP choices) when I am hungry (stop when I am not) and weigh in at a steady 184 lbs (6'3") for almost 2 years now. I don't know if it will work for everyone, but that simple idea of eating/playing/living seems a hell of a lot more appealing than constantly measuring, counting, weighing, tracking, analyzing. And from the anecdotal responses of many struggling with weight, just eating less and moving more, ignores this important aspect of the inter-dependencies of what type of calorie you actually eat and the metabolic function/physiological responses they produce. All calories are not created equal. A lot of this goes against conventional wisdom of what we have been told is healthy for us for many years now (low fat, whole grain etc...). It hard to fathom, but until we have some real science performed (no... meta studies and causation by correlation are not true scientific experimentation), the conclusive results will elude us. Until then I go with what works for me.
