For some people the first few days of ‘cutting carbs’ is difficult. After all your system may have running on sugar for years, this is a metabolic shock! It takes a while for the system to swap to burning fat as fuel instead. Make sure you are drinking enough water. Odd as it sounds many people find they need extra salt on a lower carb diet. Interestingly this is because the sugar hormone – insulin causes you to retain salt- so cutting sugar may result in ‘weeing out’ salt you had been hanging onto for some time. In its turn this loss of salt can improve your blood pressure. I remember I suddenly started feeling dizzy if I stood up too quickly! Some doctors find their patients are able to reduce their BP medications. For the same reason some find muscle cramps and weakness are a problem. Again, more salt is the remedy, sometimes magnesium supplements also help with this.
