Do you keep it within a certain caloric deficit (500-700 calories consumed for the day)? What kind of foods do you eat to ensure you don’t get the shakes or lightheaded during the day? Do you focus on fat or protein? Or do you not eat at all?
I don’t eat at all. I enjoy fasting for it’s simplicity. I hate having to obsess over calories on my fast days. I’m the “oh I messed up today let me just binge for the week and start fresh on Monday” kind of person. So not eating at all puts my mind at ease.
When I fast I fast. So no food. I used to have problems with lightheadedness and actually I am a fainter. Not a graceful fainter either. I fold up like a jacobs ladder and twitch. That was fixed when I switched to low carb and/or supplemented electrolytes.
I can go full carb and then fast now with no issues, my body adapts quickly now but that tool time. You can get rid of the lightheadedness by either getting keto adapted before a fast or immediatly supplementing salt can help. Depends if its blood sugar crash or low blood pressure or low electrolyte. For me it was all 3. Low sugar used to make me feel shakey and vibrating internally. Low blood pressure and salt made me feel dizzy and hollow. The two together made me pass out lol.
Fasting to get control of my blood sugar and get back into keto is what really saved my ass on binge days. Now I don’t live in fear of fainting
