I Dropped 14 Pounds in 30 Days Using This Weird Fasting Trick

Learn how to lose weight with alternate fasting.
FACT CHECKED BY Christopher Roback

Do you want to lose weight fast? Fasting may be able to help with that. However, before you get started, understand there are several methods you can try. Brendan Jones, a YouTuber, and one-half of Goal Guys, a channel devoted to fitness and productivity, tries out various diet and exercise methods and reports back on his findings. In a recent viral video, he explains alternate fasting, revealing exactly how it helped him lose 10 pounds of body fat and 14 pounds overall in 30 days.

He Starts By Getting a Full Body Scan

He started by explaining that he got a full body DEXA scan "to measure my lean body mass percentage of body fat and a number of other things I probably won't understand," he says. "The reason I got this scan is because I'd like to measure how much body fat I can lose through a science-based fasting regimen."

Here Is What Alternate Day Fasting Means

"I was doing some research, and I came across two really interesting studies on something I'd never heard of before called alternate-day fasting. And it's exactly what it sounds like," he continues. "You can eat as much as you like within a 12-hour window on day one and then abstain from eating the remaining 36 hours until you complete day two. Repeat these steps over and over until your fast is complete."

Studies Found It Was More Effective for Fat Loss Compared to Calorie Restricted Diets

"In both studies, subjects who did alternate day fasting saw greater fat loss compared to control groups who did traditional calorie-restricted diets, and subjects who were already in decent health also saw improvements in their overall cardiac health. Neither study found any negative side effects, but do call for additional studies. And, of course, you should consult a doctor before taking on any fast that lasts longer than 24 hours," he continued.

He Created a 30-Day Plan

"My goal this month is to give alternate day fasting a try for 30 days and then get a follow-up scan to see if it had any positive effects on my fat loss. And contrast that with any perhaps negative consequences in reduction of muscle mass or any other changes to my overall health. That is, of course, assuming I make it in the next 30 days," he says.

Before he gets started, he sets himself up for success. "I start by putting away any food that's displayed inside my kitchen. So there are no visual cues to remind me to eat as a safety precaution," he says.

He Also Looks Out for Malnourishment Signs

He also looks out for health signs. "I'm gonna be watching for trouble signs like fatigue, dizziness, or headaches, which could indicate malnourishment," he says.

He Weighs Himself Every 7 Days

He also recommends regular weigh-ins. "I'll be monitoring my weight every seven days to make sure I'm not dropping pounds at an alarming pace," he says.

He Keeps Himself "Occupied" to Make It Through Day One

"My next step is to make it through day one without breaking. So I've written out an ambitious to-do list to keep myself occupied, hopefully leaving less time to think about how hungry I'm getting," he says.

Eating Enough Protein Is Key

His eating hours are 7 to 7. "It's really important I'm getting the most out of each meal. So I'm starting today with a breakfast of scrambled eggs and tofu for a high source of protein, and I'm going to be serving that on multigrain toast with a side of brown bean," he says.

He Meal Preps

After breakfast, he meal preps a quinoa salad with broccoli and sweet potato, "so I have a healthy source of carbs, protein, and vitamins for my second and fourth meals today," he says. "On days that I can eat, I want to push myself as hard as I can with these workouts because I expect on fasting days I won't have the energy to do nearly as much."

He Starts Exercising on Day 3

He also starts exercising. "When day three arrives, I'm able to get a short run and work out first thing in the morning while my body still feels full from the previous day's eating."

One week in, and "so far things are going pretty well," he says. "I have lost five pounds, which I know is mostly water weight at this point," he adds. "I usually get my worst hunger cravings between six to 8:00 PM, but by that point, I'm on the home stretch, and I know food is coming in the morning, so I usually have that knowledge just to persevere, drink some water, drink some tea, and keep going."

He Says That He Has a "Significant Boost in Mental Energy" on Fasting Days

"Another thing I've noticed on fasting days is a significant boost in mental energy," he says. "Even though I'm less physically active on days I'm not eating, I find I'm able to stay alert and concentrate well into the evening despite cutting my coffee, drinking down by more than half. And I don't want to guess the reasons why so many studies have found positive benefits from fasting that go beyond just fat loss."

He Believes Obesity Is Due to "Frequency, " Portion Sizes, Added Sugars and Fats

"When you look at the frequency of our meals, along with the portion sizes and added sugars and fats we've come to expect as part of our diet, it's no surprise so many people in North America struggle with weight. At least that's what I'm telling myself because, according to my DEXA scan, I'm obese. According to the American Council on Exercise, anything above 25% body fat for men is considered obese. My score came in at 27%, and I got the scan during a time when I was ranked 30 to 40 kilometers a week, and I stayed consistent with the gym," he continued.

He Attributes His Fat Due to "Overindulgence in Unhappy Snacking"

He added that he holds the majority of fat in his hips and waist, "a little bit around the shoulders and arms and a little bit on the inside of my legs," he says. "All of this, I think, is caused by a lack of portion control in my diet and an overindulgence in unhappy snacking."

He Recommends Interval Training

Exercise helps maximize fat loss. He recommends interval training. "You have moments where you're doing quick bouts of work, and then you have a rest period, which just gives your body some time to recover, and then you go back in again. And that helps with your energy level, and it's not going to tire you out as much on the days that you're fasting," he says.

"When I finally get back to the gym, I want to pay specific attention to my abs, lower back, and obliques," he says. This is to "build muscle in the areas that are high in fat." However, "I'm still maintaining the exercises I do for the rest of my body as well," he says. He also does cardio.

"When it's time for my second body scan. I've lost 14 pounds in 30 days, but the question I still want to answer is, how much of that weight loss was fat? Nine and a half pounds. I lost nine and a half pounds of fat with this routine and cut my percentage of body fat down by 4% in four weeks with the majority of those losses coming from waist and trunk region," he says.

He Says It Was Easier Than Restricting Calories

"Perhaps the only disappointment from these results was the almost three pounds of lean mass I also lost, which is pretty consistent with what I would've expected from a calorie-restricted diet," he says. "So it doesn't look like alternate-day fasting is a magic bullet for preserving muscle mass at the same time you're trying to burn fat. But in my opinion, anyway, trying to stay consistent with a fasting regimen was much easier than staying consistent with a calorie-restricted or crash diet that involved constantly monitoring your portions and making sure you stay below a daily target."

It Gave Him the Freedom to Enjoy Cheat Meals

"I found this routine not only decreased my appetite over time, but it also still allowed me the freedom to enjoy a pizza or popcorn on occasion without compromising my progress," he says. "The one exception to this dietary freedom, though, is with the first meal you eat at the end of a fast period for that meal, it's really important that you're eating some complex carbs that take time for your body to break down and convert into glucose. Things like whole grains, black beans, sweet potato, or quinoa are all great.  If you start your day with white bread and a lot of fruit, those foods will quickly break down into sugar and prevent your body from burning fat. So that first meal is really important."

"Based on just my own experience, I found fasting to be a really valuable tool that I honestly wish I'd started using a lot earlier in life. But going forward, I am going to look into a less extreme fasting regimen, probably something closer to intermittent fasting or even just modifying my fast days so they include some form of eating something like rice cakes and a protein shake or a black bean burrito with sweet potato and broccoli," he says. "Either way, after getting my DEXA scan, I know I have more work to do, and I'm gonna continue utilizing fasting to help as I go forward."  And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.
