As it applies to strength training, the keto diet is almost mandatory if you plan on lifting more weight. My argument is that for the simple fact the stomach can only handle a fixed volume of food and since protein consumption is absolutely necessary for muscle building, one must adapt one's diet to a ketogenic diet.
Typically keto diets are high fat, moderate protein and low carb. The strength trainer's diet is high protein, moderate fat, low carb. High protein for muscle building. Moderate fat to keep blood insulin levels stabilized which facilitates muscle protein synthesis. Low carb again to keep blood insulin levels low.
This represents the perfect ketogenic meal for while working out and up until 48 hours after the workout. It's chicken and guacamole. The guacamole has tomatoes, onion and avocado so it's not perfectly ketogenic but it's pretty close because it has only 50 grams of carbs. If you still feel lightheaded after eating this, eat a couple slices of bread to feed your brain glucose.
I'm beginning to think that during your workout, what matters most is how low you can keep your blood insulin levels. I used to think that an abundant protein intake was necessary for making personal records in your lifts but now I'm beginning to see that when you keep blood levels low, not only is the need for protein less but also I feel much stronger because my blood insulin levels are kept from spiking too high thanks to the use of avocado during the workout.
