Of course, most people use IF with another weight-loss plan. For instance, you might decide to eat 1,200 calories a day to lose weight. You may find it much easier to spread out 1,200 calories within two meals and two snacks than in three meals and three snacks. If you’ve struggled with weight loss because your diet either didn’t work or was simply too hard to stick to, you might try intermittent fasting for quicker results.
I’ll share some of my experiences, now doing heavy strength training for 3 years in a fasted state: For my first “fasted” workout or two after starting an IF protocol, it was very weird to not eat before training. However, after a few sessions, I learned that my body could certainly function (and even thrive) during my training sessions despite not eating a pre-workout meal.
Eat one large meal per day, cutting out all other meals and snacks. For those who aren’t interested in checking clocks and calendars, this is probably the easiest option. This is also a good choice for busy individuals who have a lot going on during the day. Just skip breakfast and lunch and have a large dinner that will carry you over through until bedtime.
None of the coffee additives caused a significant drop in our blood ketone levels. At 120 minutes, my, (Becky’s), ketone readings increased after drinking black coffee, coffee with cream, coffee with MCT oil, and coffee with butter. At 120 minutes, Keith’s ketone readings dropped by 0.1 mmol/L after drinking only black coffee. His ketone readings rose slightly after consuming coffee with cream, MCT oil, and butter.
Also if you are looking for an amazing workout and diet program that gets results, I highly recommend you take a look at my page reviewing the Kinobody system in, Is Kinobody A Scam? I have purchased this program and can’t recommend it enough. Life Changing and easier than you think. I also have written a post about his Kinobody Style Guide, that spells out how to dress better. It can be found here, Kinobody Style Course.
How It Works: Fast for 14 (women) to 16 (men) hours each day, and then “feed” for the remaining eight to 10 hours. During the fasting period, you consume no calories. However, black coffee, calorie-free sweeteners, diet soda and sugar-free gum are permitted. (A splash of milk in your coffee won’t hurt, either.) Most practitioners will find it easiest to fast through the night and into the morning. They usually break the fast roughly six hours after waking up. This schedule is adaptable to any person’s lifestyle, but maintaining a consistent feeding window time is important. Otherwise, hormones in the body can get thrown out of whack and make sticking to the program harder, Berkhan says.
Most people make an IF schedule that requires them to fast for 12 to 16 hours a day. During the rest of the time, they eat normal meals and snacks. Sticking to this eating window isn’t as hard at it sounds because most people sleep for about eight of their fasting hours. In addition you’re encouraged to enjoy zero-calorie drinks, like water, tea, and coffee.
16-hour fast (aka 16:8): The most popular type of intermittent fast, the 16-hour fast encourages you to eat all of your meals in an 8-hour window, such as noon to 8pm. To activate the full benefits of intermittent fasting, try an 18-hour fast, once you’ve adapted to 16 hours. This would mean eating between noon and 6pm or between 2pm and 8pm. Simply avoid eating after dinner, and skip breakfast in the morning. Limit carbs to dinner.
It requires less time (and potentially less money). Rather than having to prepare or purchase three to six meals a day, you only need to prepare two meals. Instead of stopping what you’re doing six times a day to eat, you simply only have to stop to eat twice. Rather than having to do the dishes six times, you only have to do them twice. Rather than having to purchase six meals a day, you only need to purchase two.
