The benefits of eating a non-carb diet are dramatic weight loss and bodyfat reduction in a short period of time. This is because the body turns to fat as its primary energy source in the absence of carbs. Now the opposing controversial effects of a non-carb diet are tiredness & lack of concentration which is because carbs provide the energy to the brain once broken down.
So the last 2weeks have been enlightening for me as I have carbs with every meal normally. Oats, Pasta, Rice, Potato, Bread & Fruit were all off limits. I pretty much went to the extreme of having chicken morning, noon & night literally with babybel's cheese being the snack of choice. The 1st 5days were the toughest with headaches, tiredness & dehydration being the main effects. Up to lunchtime would be fine but by the early evening I found myself feeling really tired & with the headaches I found myself becoming a bit ratty (luckily my clients didn't realise as I concealed the feeling, the fact they see that as my normal behaviour is a bit alarming. Maybe I am an evil sadist). Anyway back were the days of afternoon naps like a baby very similar to what was needed in my last experiment, 1hr would normally do the trick. On another note, no amount of water that I drank would seem to quench my thirst always feeling dehydrated (some days drinking over 3ltrs) & with a horrible dry taste in my mouth, mouthwash was never far away to freshen up. As I began to get annoyed with the constant tiredness & headaches there it was, the silver lining. I had Just finished a light workout (I didn't have the energy to muster anything else) and I was about to go in the shower when I glimpsed my reflection (vein much?!) my abs were showing quite a bit more than before & with just 5days gone even if for a short moment all the negative feelings towards the 'no carb diet' disappeared. Now I know to start with my stomach is fairly toned but the more you get into training the more you look to improve & fine tune the minute of details, so to see this little improvement was something of an achievement. "This no carb malarkey isn't half bad", I allowed myself to think but that all came crashing down at my track sessions on Sundays at Ladywell Arena, Catford, 11am, all are welcome (had to plug it a little). Luckily for me the weather or for whatever reason had resulted in no one turning up. I was there on me tod and quite relieved as even though it was morning I had already felt tired, so I planned a light sprint session. Rocking up about 15-20mins late came my cousin to join in the fun, there & then I knew I would have to work harder than planned. So the structure of our sprint sessions goes 3x150m, 3x100m & 3x50m all ran flat out at maximum effort. The 1st 2 150's I got through with relative ease and I guess the ego got the best of me as we started to stagger the starts and as they usually do, for the better I must add it got a bit competitive. I now decided that I would have to run down my cousin who had a head-start and therefore run 2 or 3 times harder. After the last 150 and 2nd 100m sprint I began to feel so light headed and nauseous that I thought I would faint (don't worry I'm not expecting any sympathy). With my blood sugar already low from the dieting I was doing myself no favours working at 90-100% capacity. When working at such a high intensity your sugar stores are usually burned up so quickly and the fat reserves are called in to use as a secondary energy source, that's why intensity training is the latest thing to be encouraged, short & high energy. So with no carbs in my system and presumably my fat stores running out I was running on empty like a Ferrari without fuel and we all know what will happen if you drive without fuel, eventually the car will breakdown. Luckily my cousin didn't push through with a request for 3x50m at the end which is surprising as when the roles are reversed I am not so forgiving which I'm sure a lot of you can vouch for. After session I was literally craving for sugar like a crack fiend and broke my diet to have a banana, believe me it was really needed. Home, eat & sleep was the order of the day after that. I've only ever felt that bad once and that was again at track but in searing heat.
Week2 it seemed that my body had become accustomed to the lack of carbs and without any high intense training I was getting through the days without needing sleep. I even went for a 10km run on Tuesday even though I ran at a slower than usual pace & it was only then the light headed feeling and rattiness reappeared. Physically I was looking even more toned & in just 10days I had lost 2kg and 2.5% of bodyfat.

| Post no carb diet 7% bodyfat |
The verdict.........
My thoughts are while I may in my opinion look better, I don't feel as good as I look and it leaves me to pose the question, "No carb diet, vanity over health, is it really worth it???" I'd have to say no, I love my crazy high intensity workouts and I can not operate normally training my clients to the best of my ability during a no carb diet when I feel lethargic. What I will change in my eating is the amount of carbs I have no longer eating carbs in the evening when the sugar isn't needed as I'm not as active (carbs not used up turns to fat). For a short period of 10days before a holiday, wedding, etc I can see the appeal as the results are amazing and very instant. All I would advise is its a false look as you cannot maintain eating that way for a long time and will resort back to size or gain more once you re-introduce carbs. So if you must, do it for only a short period, this is not a healthy long term solution. Its simple exercise, work hard & eat a healthy balanced diet.
