Pet peeves of little experiments like this of carb cutting. Cutting carbs causes you to shed a lot of water weight. Also if the exercise is new it is quite possible that is the bigger factor in improving perceived cognitive ability. If you changed multiple things and started paying closer attention to diet it is really hard to pin down what actually helped the most. Vigorous exercise helps clear waste along with sleep, not much else really clears things out -- brain seems more and more to be a part of, or similar to, the lymph system. edit: also most people who do 18 hour fasts report feeling energized, better concentration, etc,. especially if they have caffeine on an empty stomach.

I've cut carbs and increased my calorie intake (through fat and protein) over the past year and have shed 70 lbs of "water weight". I went from Obese to a healthy weight, from a 42" waist to a 32" waist. And I've actually decreased the amount of exercise I've done, too. Amazing how much "water weight" all those fat cells were holding.

  How can you be sure that it was being low on carbs, as opposed to consuming less calories overall, that was the cause of your sustained weight loss?

    I switched from a calorie restricted "balanced" diet (1900 kcal/day, 150g carbs/day) with small portions that was going nowhere to an unrestricted (>2500 kcal/day, <30g carbs/day) diet with larger portions and lost weight.

      And you're measuring everything with a food log? When I do a low carb diet, even unrestricted, I have to focus (eat on a timed schedule) on getting enough calories to maintain my lean mass. Without carbs I simply do not eat enough naturally to maintain a weight I want to keep.

      This is interesting. I'd like to learn more. Are their studies that demonstrate that consuming more calories (with different composition such as HFLC) leads to weight loss compared to lesser calories (regardless of composition)?

  I think that he is referring to the immediate weight loss effects associated with depleting the glycogen stores in your liver (400 grams) and muscles (100 grams). Each gram of glycogen is bound to 3 - 4 grams of water. Thus, depletion of your glycogen stores results in the loss of 2.0 - 2.5 kilograms (4.4 - 5.5 pounds) of "water (and glycogen) weight" within the first week of a low-carb diet. Larger individuals often retain even more glycogen and water, which can result in immediate losses of 6 kilograms (13.2 pounds) or more. His point is that some studies, particularly short term studies, do not account for this non-fat weight loss.

  Out of interest, how many grams of carbs/day did you cut down to?

    under 30, almost all from green vegetables.

      Wonderful to hear. Please continue to post. How much of your fat intake is saturated? I greatly increased my saturated fat intake and saw the associated quality of life improvements you'd expect (included increased free testosterone).

  Referring specifically to folks who change diet and report 6-12 lbs of weight loss in 1 or 2 weeks. Can't burn fat that fast. Carbs in excess cause cells to hold more water, this is a fact. Diet changes, especially water loading, macro nutrient ratio changes,and exercise can cause big shifts on a small time frame. Recommend hacker's diet style of weight trending vs scale measurements to measure short term weight loss.

  You were most likely underestimating your calorie intake at first, it is a common issue. See: https://www.ncbi.nlm.nih.gov/pubmed/1454084 https://www.ncbi.nlm.nih.gov/pubmed/1454084 Discrepancy between self-reported and actual caloric intake and exercise in obese subjects. Also, switching to a diet higher in protein tends to make people eat less calories and consequently lose fat. https://www.ncbi.nlm.nih.gov/pubmed/16002798 https://www.ncbi.nlm.nih.gov/pubmed/16002798 An increase in dietary protein from 15% to 30% of energy at a constant carbohydrate intake produces a sustained decrease in ad libitum caloric intake that may be mediated by increased central nervous system leptin sensitivity and results in significant weight loss. This anorexic effect of protein may contribute to the weight loss produced by low-carbohydrate diets. So in reality, the reasonable explanation is that you decreased your calories involuntary by upping your protein intake.

Note this study was not about carb cutting, "high fat" in this context means high fat + high sugar, a combo specifically designed and proven to fatten mice. 60% lard, 20% sucrose, 20% casein.

The exercise (ocean swim) isn't new. I've been doing it for years. And yes - it does help enormously (e.g to get the blood really flowing well) - as long as I get the start time, duration, intensity and intervals about right. I tend to swim only until just after the point that I reach peak performance. Also, (for me) it isn't just about carb cutting - it's about timing. If I eat a medium bowl of white rice at a breakfast, then I tend to feel worse afterwards and I put on (some) weight. If think that the blood gets thicker and stickier as blood sugar rises and so blood flow gets worse. If I eat the same medium bowl of white rice after my swim then I don't seem to put on weight, but it does help avoid a next day energy crash. I also paid it with 5g of Creatine Monohydrate (before the swim) and the combination seems to have reversed my middle-age loss of muscle. What doesn't work for me is vigorous early morning exercise fueled by caffeine. Again for me, that is the route to over -training and a long bout of fatigue. YMMV. Listen to your body.
