When you get to one meal a day, just make sure the meal is a robust one, containing all the needed nutrients to fortify your body with vitamins, minerals, amino acids, those important fatty acids, trace minerals—all of it. (This can be aided with green drink powders and high-quality electrolyte supplements that will help you get your daily requirements for potassium.)
Fat is the cornerstone of the keto diet, making up the bulk of calories. An individual consuming 2,000 calories per day would need to consume 144 to 177 grams of fat. Fats make up 70-80% of your calories. Since fat is the main source of nutrition on a ketogenic diet, it’s important to source high-quality, healthy fats, which you’ll read about below.
While macros will differ a little from person to person, the general rule of thumb for keto is to keep carbohydrates under 5% of your daily caloric intake. As long as you avoid the foods mentioned above, you should be fine. Google “TDEE calculator” if you need some additional guidance on how many calories to eat. I’ve had success following this way of eating as it allows me to eat foods that taste great. There are tons of resources online as well if you need additional guidance. A quick google search should turn up a ton of resources. Hope this helps!
This week we’re getting stricter with our fasting. We had a full week of intermittent fasting and now we’re going to skip breakfast and lunch. Water is our BEST friend here! Don’t forget that you can drink coffee, tea, flavored water, and the like to get your liquids in. Keep drinking to make sure you’re not thinking about your stomach. It MIGHT start growling, just ignore it – your body will adjust with time.
In short, no. Apples even have too many carbs. Pineapples hugely spike insulin. Never consume fruit juices. The fiber is bound to the phytonutrients and the juice is cooked, removing many nutrients. You’re basically just drinking concentrated fructose + corn syrup. As an adult, I wouldn’t consume much fruit, period—except maybe ½ cup berries a day. Fructose consumption can lead to a fatty liver, insulin resistance and can spike insulin MORE THAN GLUCOSE!
Your glycogen stores can still be refilled while on a ketogenic diet. A keto diet is an excellent way to build muscle, but protein intake is crucial here. It’s suggested that if you are looking to gain mass, you should be taking in about 1.0 – 1.2g protein per lean pound of body mass. Putting muscle on may be slower on a ketogenic diet, but that’s because your total body fat is not increasing as much.5Note that in the beginning of a ketogenic diet, both endurance athletes and obese individuals see a physical performance for the first week of transition.
