The ketogenic diet has surged in popularity as an effective method for weight loss and improving overall health. This high-fat, low-carb diet forces the body to switch its primary fuel source from glucose to ketones, derived from fat. This metabolic shift, known as ketosis, can lead to significant changes in body composition and various health markers. Many individuals have shared their experiences and "before and after" photos, offering inspiration and proof of the diet's potential. While it requires somewhat drastic changes to the way you eat, it can also take as little as a week or even a few days for your body to enter ketosis, where your body starts burning fat instead of carbs for energy.
Understanding the Keto Diet
The keto diet involves drastically reducing carbohydrate intake to just 5-10% of total caloric intake. "Typically, your body uses glucose for energy. But when you're carbs are cut drastically to five to 10 percent of your total caloric intake, your body uses ketone bodies (converted from fat). And that becomes your body's source of energy," she explains. This forces the body to break down fats into ketones, which then become the primary energy source. This metabolic state is associated with weight loss, improved blood sugar control, and other health benefits.
Initial Weight Loss and Long-Term Expectations
You're ditching water weight initially, but from there, how much weight you lose depends on how well you stick to the lifestyle. A safe rate of weight loss is between one to two pounds per week, according to the National Institutes of Health. Because it's so restrictive, this diet isn't really meant to be done long-term, according to Scott Keatley, RD, of Keatley Medical Nutrition Therapy. The best way to determine if the keto diet is for you is to talk about it with your doctor.
Inspiring Keto Success Stories
Many individuals have found success with the keto diet, achieving significant weight loss and improvements in their health. Here are a few inspiring stories:
Kay's Transformation: 150 Pounds Lost
Kay had felt stuck struggling with her weight and rheumatoid arthritis for years. "In May 2018 I was at 402 pounds and I was shocked,” says Kay. She realized that the problem was a combination of the high-carb diet her trainer had recommended as well as her rigorous exercise routine. Once in ketosis, it was like a light switch had flipped. Through the keto diet, Kay has not only lost a staggering 150 pounds in the past year, but she’s also learned how important it is to take care of her body, how to feel more beautiful in her own skin, no matter what weight she’s at, and her energy levels have improved significantly. As a result of her own transformation, Kay has become incredibly passionate about inspiring others to take action and lose weight the healthy way.

Michael Searls: Lost 100 Pounds
Michael Searls vividly recalls the time he knew his weight had gotten out of hand. He was in the store buying pants-he knew he'd put on a few pounds, and figured he was now too big for his usual 32 or 34 waist size. After he tried sliding on a pair of 38's, however, he realized they were still nowhere close to fitting. "I panicked that day. I ended up putting on a size 46, and I remember being in the fitting room just looking at myself with tears in my eyes, not believing I was that size," he says.
Matt Clemente: Lost 200 Pounds
Matt Clemente was in his late thirties and weighed 417 pounds. He was sleeping two to three hours a night, getting exercise only through trips upstairs to his office and back down for coffee. At first, his joints would creak. Then his legs started to buckle. And then, the kidney stone. Clemente was so large that doctors had to do invasive surgery to get rid of it. After the most painful, excruciating ordeal of his life, Clemente was done: “I can’t go through this anymore,” he said to himself. Over the next two years, Clemente would lose over 200 pounds, pack on muscle, and reach a stocky 207 pounds, running Spartan races and doing CrossFit.
Andrew Kim: Lost 90 Pounds
Andrew Kam is a realist. At 27 years old, he’s been through enough to know there’s no magic pill that will make you happy, and no quick fix to getting healthy. As a kid, Kam noticed he was always bigger than other kids. Though he was bigger, Kam’s weight issues compounded during freshman year of college, when his mother died after battling cancer. Kam went to therapy to deal with his grief and other mental health issues. But as he began eating foods that comforted him, his physical health took a turn for the worse.
Ethan Spiezer: Lost 130 Pounds
Ethan Spiezer had always been an emotional eater-growing up, he frequently turned to food for comfort during challenging times. As a result, by the time he reached middle school, Spiezer recalls, he weighed nearly 200 pounds. When his weight peaked in his mid-thirties, Spiezer estimates that he weighed between 410 and 420 pounds. The turning point proved to be a photo that a bystander took of Spiezer and his son during a boat tour while on vacation in San Diego. Spiezer decided that day to commit to eating healthier and being more active, and has since undergone a dramatic weight loss transformation, dropping more than 135 pounds in less than year.
Jeremiah Peterson: Lost 92 Pounds
As a kid in the 1980s, Jeremiah Peterson made the commitment to get fit - not just for his looks, but to fight off the bullies, too. It was knowledge that would serve him well later in life, when he found himself as a 40-year-old man who was 100 pounds overweight and in need of yet another lifestyle transformation. Peterson was also being bullied at school, so he wanted to get fit to protect himself and "anyone else that couldn’t protect themselves."

"I had to get up and exit the ride because I was too big, he says. The episode was the first in a series of turning points that convinced Gutierrez it was time to get healthy. "Another bad incident was at the airport," he continues. "I went to board my flight and the belt didn’t want to close all the way. I had to suck in my stomach as much as possible for the plane to take off. I delayed the flight because I couldn’t buckle up."
Tim Kirkwood: Lost 250 Pounds

Eric Clarke: Lost 190 Pounds
Eric Clarke started gaining weight in middle school. A football lineman on his high school team, weighing more was an advantage, so Clarke thought nothing of that extra weight.

Kevin Ozee: Lost 130 Pounds
A nightmare forced Kevin Ozee into making a change. "I dreamt that my wife and kids were attending my funeral.

At the time Ozee weighed 345 pounds. Now, he's 213 pounds, thanks to the Keto Diet.
A Personal Keto Journey: A 3-Month Experience
One individual shared their experience of following the keto diet for three months. Adhering strictly to the plan, staying within macronutrient limits, and avoiding cheat days led to significant results. The individual lost several inches of waistline and had to purchase new work clothes.
Tactics for Success
- Support System: Having support from a spouse or partner can be invaluable. This support can include help with grocery shopping and creating a dedicated space for keto-friendly foods.
- Meal Planning: Planning meals in advance is crucial for staying on track. Pick out 3-4 dinner/lunches from the recipe book and come up with a breakfast plan for the week, and then go get the necessary ingredients for all that food. Keeping myself to a specific planned list of meals helped keep cheating out of bounds.
- Carb and Sugar Awareness: Understanding the carbohydrate content of different foods is essential. Realizing that even seemingly healthy foods like bread and starchy vegetables can be high in carbs is important for making informed food choices. For example, one slice of bread is already 32 grams of carbs. They are also in starchy vegetables like carrots, potatoes, corn, beets.
- Meal Tracking: Using a meal tracking app can help monitor macronutrient intake and ensure adherence to the keto diet.
- Daily Weigh-Ins: Weighing oneself daily can provide valuable feedback and help maintain motivation. I weigh myself daily and found the range of weight and body fat percentage that I can comfortably maintain.
Month-by-Month Breakdown
- Month 1: The initial weeks can be challenging as the body adapts to using fat for fuel. This period, often referred to as the "keto flu," can involve symptoms like low energy. Staying hydrated and consuming healthy fats can help mitigate these effects. Within the first 3 weeks, I had lost 6 pounds. I did get the Keto flu and trying to power through my workday with low to no energy was painful. I took the expert advice of drinking lots of water when I woke up, tried to stick to eating carbs early on in the day and not in the evening, and switched over to eating healthy fats (avocadoes will be your new best friend).
- Month 2: Weight loss may continue, although possibly at a slower pace. It's important to avoid overindulging in unhealthy fats and to be mindful of hidden sugars in "keto-friendly" desserts. I ended gaining back some of the weight I lost because while fatty meat can provide fats and protein, having too much of it means you consume too much protein, which converts into glucose in the body (same as what carbs convert into so it’s not good).
- Month 3: Experimenting with different keto-friendly foods and recipes can help maintain interest and enjoyment in the diet. Discovering new favorites, such as fatty fish, can make the diet more sustainable. I also started grilling salmon filets at home with lemon juice, garlic, and herbs. If you love fatty food, you will find the aromatic and crispy fish skin a godsent.
Positive Effects Experienced
- Weight Maintenance: The keto diet can be effective for maintaining weight, especially when workout routines are disrupted.
- Increased Productivity: Many individuals report experiencing increased energy levels and mental clarity on the keto diet, leading to improved productivity.
Key Strategies for Keto Success
Based on the experiences of successful keto dieters, here are some key strategies:
- Prioritize Healthy Fats: Focus on consuming clean, healthy fats like C8 MCT oil. When it comes to healthy fat, C8 MCT oil is commonly recognized as the most keto-friendly oil thanks to its impressive ability to increase ketone production in the bloodstream.
- Minimize Carbs: Eating minimal carbs is essential for priming the body for fat-burning.
- Plan Your Meals: Plan your meals in advance and use a meal tracking app.
- Don't Be Afraid to Be Lenient: While consistency is important, it's okay to be lenient with your diet every now and then.
- Start Right Back: “If you fall off your diet, immediately start right back. Don’t stop. Keep going.
- Use Electrolyte Supplements: I would have started using electrolyte supplements sooner, especially when I would work out.
Additional Tips and Considerations
- Listen to Your Body: One of the greatest benefits of following a high-fat diet like keto is how satiating it is. If you find yourself not wanting to eat for long stretches of time while doing keto, don’t be alarmed.
- Find Healthy Replacements: I use chorizo in a lot more ingredients, and fried queso fresco is now a treat I make for gatherings.
- Consider the Long Term: Will it be the easiest thing giving up sugar and carbs? Definitely not. But after the first month, your body starts preferring meat instead of sweets and carbs.
