IndustryStandard If you’ve never tried a low carb or keto (<30 grams of carbs/day), it’ll take 90 days to get fat adapted (the point where your body has really adjusted to burning fat over carbs) and 6 months to really start to optimize fat burning.
The key is to start slow, it’ll feel like you’re dying for a couple of weeks if you cut carbs cold turkey (which I did), and ease into exercise. Keep everything in zone ½ (top of zone 2 is equal to your fat max state), which means you can hold a conversation while running/biking. It should feel easy. The benefits start at 30-40 minutes of continuous exercise and personally, I found it goes into overdrive at 90 minutes.
Initially it can be a difficult transition, but I’ve never felt better physically (reduced inflammation) and mentally (clarity of thought, better memory, improved motivation) than when I was strict keto.
