After determining your preferred protocol of intermittent fasting, you should start planning out your diet for the days that you do eat. On a standard keto diet, 75 percent of total calories should come from fat, 20 percent should be from protein and 5 percent should come from carbs. When getting started, however, you can start with a modified keto diet instead, which is often considered more flexible and easy-to-follow. With this diet plan, about 40–60 percent of calories should come from healthy keto fats with 20–30 percent from protein foods and 15–25 percent from carbohydrates.
I don’t recommend that you go straight for a 1-2 day fast, but begin by restricting yourself to certain eating windows. Typically people restrict themselves to the hours of 5pm – 11pm. People often refer to their fasting windows by numbers: 19/5 or 21/3, for example, means 19 hours of fasting and 5 hours eating or 21 hours fasting and 3 hours eating, respectively.
Cons: Even though it’s nice to eat a few snacks rather than go without any food for 20-plus hours, the guidelines for what you need to eat (and when) can be hard to follow long-term. The strict schedule and meal plan may also interfere with social gatherings. Additionally, eating one main meal at night — while following strict guidelines of what to eat, and in what order — can be tough. It’s especially hard for those who prefer not to eat large meals late in the day.
Intermittent fasting may work amazingly well for some people, and terribly for others. Most importantly, if you do decide to give intermittent fasting a try, be sure to listen to your body’s feedback. Easing into intermittent fasting by starting with shorter fasting windows can help with initial symptoms of hunger and discomfort. But if it becomes too uncomfortable, be honest with yourself, accept it, and move on.
The problem is that we tend to spend so much time in the fed state, fueling our bodies exclusively with glucose, that we become addicted. Once the flow of glucose stops and our insulin levels drop, we start getting hunger pains. This is one of the reasons that overweight individuals — people with more than adequate energy stores in their fat cells — often have such a difficult time cutting back on food intake. They’re not starving, but they’re not getting the glucose their bodies are used to.
I started IT about 6 weeks ago. I eat between 12 noon and 8 pm. This works best for me and I have found easily sustainable. The results so far have blown my mind. I have an autoimmune disease and struggled with bloating, multiple food intolerance, gut pain, frequent urination, sugar cravings. All of these symptoms are gone. My hunger is controlled and I can enjoy lovely family dinners again. I think ideally eating earlier in the day would be better, but due to my schedule this works better for me and I am happy with the results.
There are different types of intermittent fasting, but the most common involves only eating within a certain window of time each day. For example, you might only eat between 12pm and 6pm each day, giving you a 6-hour “feeding” window when you eat all of your calories for the day. That means you’ll be fasting for 18 hours in between. Your intermittent fasting ratio would then be 18/6.
It can level up your brain, including positively counteracting conditions like Parkinson’s, Alzheimer’s, and dementia. As explained here in this TEDx talk by Mark Mattson, Professor at Johns Hopkins University and Chief of the Laboratory of Neurosciences at the National Institute on Aging fasting is grounded in serious research and more studies are coming out showing the benefits:
