Have you tried that workout you knew you could nailed but you failed? I can not speak for you. I can however share my experience.
I agree to no carbs for a few days with a friend of mine. The first day I was a bit slow, thought it was my lack of water intake. Some days I am busy so getting in the water can be a bit hectic, especially when I am not close to the little excretion room.
The second day I was unable to complete my workout. A thirty pound dumbell felt like 100 pounds, 15 pounds was as heavy. I did complete my workout but with 5 and 8 pound dumbells, with a struggle. I was wasted afterwards.
My discussion with my friend was as follow. Are you consuming the right type of carbs and how much? Then came the list, I listened and it took every ounce of remaining strength to restrain myself from a scream.
I followed someone who ate every unhealthy carb. on the market.
First and far most to anyone on a diet free of carbs, you are doing your body an injustice. Punish yourself and learn about healthy carbs, go ahead now read on it. WE NEED CARBS. Carbs create energy to help tackle those unwanted inches, pounds and fat. The carbs must be the healthy ones and there are many.
