Ketones (beta-hydroxybutyrate [BOHB] and acetoacetate [AcAc]) are produced by the liver when both serum insulin and liver glycogen levels are low (McGarry 1973).  They can be made from fat stored in the liver, from fat released from body adipose reserves and delivered via the bloodstream; or they can be made from dietary fat entering the bloodstream after digestion and absorption as chylomicrons.  In other words, once fat is in the body as adipose reserves or absorbed dietary fat, liver ketone production is a function of blood insulin and liver glycogen content.  There is no special relationship between mobilization of body fat stores (i.e., weight loss) and blood ketone levels.
It's also important to consider the dangerous health effects of not eating in certain populations, like those with insulin dependent diabetes. If you are taking insulin and not eating, your body does not have glucose available to utilize and you could become hypoglycemic. If you are considering intermittent fasting as a way to control calories, always speak with your doctor beforehand. 
If you tend to carry weight around your waist, you're not alone — it's one of the most stubborn areas to lose weight!

Once your body runs out of glycogen stores, it is forced to break down protein and fat for energy, pending how much oxygen is available. And it typically takes about 12 hours for this to occur. In theory one would assume working out fasted in the morning - after more than 12 hours without intake - would promote more fat burning. But the science does not support this (112,113). In addition, working out fasted may effect your energy and strength, making your workout a little less intense than if you have fueled prior. These factors could effect your ability to build lean mass and perform. 

Chronic migraines were what first inspired Amanda Tagge to start exercising. “I was hoping to find some relief from my headaches and working out did help but I realized that if I really wanted to feel better I needed to revamp my health habits overall and lose weight,” she says. The more she changed, the better her headaches got and she lost 70 pounds in the process which helped her feel even better. Focusing on all the ways her health was improving kept her going even when the scale wasn’t moving.

You could be gaining muscle mass. If you are feeling more slim and stronger, or your clothes are fitting better, but the number on the scale won't budge/is increasing, you might be putting on lean mass. This is a good thing! Muscle takes up less space than fat, helping you look lean, even at a higher weight. It is also more metabolic, helping you stay in shape more easily. You can double check this, by measuring your body fat percentage or taking physical measurements using measuring tape. Keep in mind, there are many different ways to measure the success of your diet. The scale is just one of them.

When you've got a lot of weight to lose, deciding where to begin can be super-overwhelming—but we've got a good place for you to start. We've talked to dozens of women who completely transformed their bodies—we're talking shedding 50-plus pounds—and pulled together a list of the eight simple changes they made that had the biggest impact on the scale. Their tried-and-true tips might be exactly what you need to get on the path to serious results. But don't just take our word for it: These women's results speak for themselves.


Your welcome! You should really follow what Sparks tells you how much to eat, for me its about 1500 – 1700 calories a day. Thats what helped me to lose weight, I wouldn’t of been able to do it without Sparks. Not eating hinders your weight lose efforts. It’s amazing that eating helps you lose weight. Shocking I know! If you don’t eat, your body goes into starvation mode and instead of burning calories it holds onto them. Enjoy food! I do as you can see. I eat healthy 80% of the time and eat not so healthy 20% of the time. If I eat bad, it’s a small portion, so I don’t go crazy not getting the foods I love, other wise this won’t work for me. This is my lifestyle now and I stopped counting calories, and I am still maintaining. I just need to exercise more, since I started this blog, I’ll admit I’ve slacked, but I do keep my weekly weigh ins. I’m glad you stopped by my site. You made me realize that I need to get back on track, because it’s easy to fall back into old habits!! Keep in contact! If you need any support, you can count on me!!


There is an app that allows you to do that, its called YouAte! I’ve been using it for several months now to track how I am eating with a simple picture, and you can add your own notes to it. Its nice because theres no calorie counting involved rather you make a mindful decision based on your own health and fitness goals of whether the meal is on or off path. Super easy and makes you aware of your decisions.

She’s a real person with real ups-and-downs, perfect for a person who is well on their way to their goal weight and a general healthy lifestyle, but sometimes takes a few steps back and struggles. Megan, like them, has downs, but her continuous determination is something you’re sure to admire.
Insulin is released when there is excess glucose or sugar present in the blood, typically after consuming a meal containing carbohydrates. Insulin works to help store glucose in muscles and fat cells for reserved fuel stores that can be used as energy when food is not being eaten, as well as maintain normal blood sugarlevels for immediate energy/bodily functions. Fat is only stored when there is a calorie excess. Having a higher lean mass and controlling blood sugar efficiently will also help ensure more of the food you eat is utilized for energy and not stored as fat. 
Think about it: If you have a big plate, it may be easy to pile on the food until the plate is full, leaving you with portions that are way too large. "Since I regularly ate balanced meals, I knew it was my portions that had to be fixed," says Erika Cataldi. "I began using toddler plates; I could load them up and still feel like I was getting a lot." That optical illusion help Cataldi drop 70 pounds.
Muscle is more dense than fat, which can make you look leaner overall. Once you reach your desired weight, you may not feel as fit and toned as you would if you lost more fat and maintained your lean mass throughout the process. In order to decrease your body fat and get toned, you would have to gain muscle mass, essentially gain weight back, and try to lean out by burning fat. It is pretty counter-intuitive to lose weight from losing muscle weight just to try and gain back more muscle weight in the end. 
Doctors recommend aiming to lose ½ to 2 pounds per week, but you'll often lose weight faster in the first few weeks after changing your diet and exercise. If you're wondering why so many diet plans promise faster results, it's because they're trying to sell you something! Extreme programs can lead to health problems, so don't try them without a doctor's supervision.
Hormonal fluctuations may effect food cravings, energy levels and muscle building capabilities, but do not directly impact weight loss or fat burning as often assumed. However, some early studies suggest that more targeted dieting based on hormonal fluctuations may be an important tool for weight reduction in women. Women may benefit from eating more protein on the days leading up to menstruation, and slightly increasing carbs and calories during the first few days of menstruation, due to higher energy demands. 

Remember that these are all perfectly understandable evolutionary design features. Higher estrogen levels during puberty drive fat gain as an energy reserve in case you get pregnant. During early pregnancy, they go into overdrive to “stock up” for the approaching challenge. Your body still hasn’t caught up to the 21st century; it still thinks its job is to keep you (a) alive, and (b) fertile in an environment of extreme food scarcity and a constant threat of famine. So storing extra fat at every opportunity makes perfect sense: back in the day, it could have meant the difference between life and death (or a healthy baby and a miscarriage).
What to eat to lose weight is a sticky subject because there are so many diets on the market right now. You must use a diet that helps you eat the best food, and you need a diet that is tailored to your body. Someone who plans to lose weight must have a diet that fits into their exercise routine, and they must be willing to eat things that they might not have eaten before.

Rather than training hungry, drink a protein shake before you go. One scoop, or about 20 grams, is sufficient. Whey is a great choice because it's easy on the stomach, quickly absorbed, and has an enormous list of additional benefits. Numerous studies have shown that ingesting more high-quality protein leads to both increases in muscle mass and decreases in fat mass.[8]
Some of us no longer have the strong joints we had as teenagers. Jogging is out of the question and walking doesn’t cut it. The good news is elliptical trainers provide an intense, low impact cardio workout. In fact, a 145-lb. person can burn about 300 calories in 30 minutes on an elliptical trainer. That’s about as many calories as running burns, but without the joint wear-and-tear.
It’s not about the fancy tricks or fast fixes. It’s not about losing 20 pounds in two weeks. It’s about the slow, day-by-day actions that turn into sustainable habits. It’s about learning how to develop sustainability and consistency. With nutrition, instead of thinking of foods in terms of yes/no lists and strict rules, it’s more about eating wholesome foods, cooking nourishing meals, and developing sustainable habits. I love cooking, exercising, and learning about living a balanced lifestyle. I am prioritizing lasting wellness.

After losing 40 pounds, certified personal trainer Gina Harney was on the hunt for guides on weight maintenance. But at the time, her options were limited. So she started The Fitnessista, which is focused on fitness advice and healthy recipes that only sound indulgent (think: pecan pie oatmeal, pumpkin pie protein smoothie bowl, and chocolate protein donuts).
3. Artificial preservatives. Namely Sodium Nitrite. Sodium Nitrite has been linked to colon cancer and lung disease. It's probably just fine if eating in small amounts. But if you're eating 2 or 3 bags of jerky each day, then you're subjecting yourself to danger. To counter this, look for preservative-free jerky. There's plenty of it out there, here's a link.
Why are you eating? Are you truly hungry or is it just that time of day? Or perhaps, there is just food around that looks good. Take a moment to think about what is driving you to eat at this particular moment and take note of any behavior that is not helping you move towards you goals. There is nothing wrong with eating when you're not hungry, or eating for pleasure, but make sure you are aware of why you are doing it and do your best to make it a positive experience free of guilt and any negative emotions. 
We know from studies of identical twins that important metabolic variables like peak aerobic power (Sundet 1994), fat mobilization in response to exercise (Bouchard 1994), and lipogenesis from carbohydrate (Kunesova 2002) are strongly influenced by genotype.  It is likely that there is considerable genetic variation around the metabolic response to nutritional ketosis, meaning that some individuals may experience an accentuated energy expenditure response when they are keto-adapted.  

I think another great thing about having a blog and being a part of the community of health blogs is how open people are with weight loss/gain. I’ve struggled with weight my whole life and never had a lot of people to talk to because people around me weren’t going through it or felt ashamed to admit guilt over gaining a few pounds or that they secretly knew all the over exercise was actually a bad thing. It can be very isolating and reading other people’s journeys is so wonderful. Thanks for sharing your story!

21. Keep it simple. "I take a minimalist approach to nutrition: My diet consists of lean protein (chicken breast, egg whites, ground turkey), complex carbs (quinoa, sweet potatoes, oatmeal), healthy fats (coconut oil, almonds, avocados), and leafy green veggies. I eat as clean as I can—locally-grown vegetables, organic when possible, and minimally-processed everything."

Besides being the preferred fuel for the brain and heart, we have recently recognized that BOHB also functions like a hormone that signals multiple changes in gene expression (aka ‘epi-genetic effects’).  Among other effects, BOHB turns on the body’s innate defenses against oxidative stress and inflammation (Schimazu 2013, Youm 2014), and it also acts to reduce insulin resistance at its source (Newman 2014).  This new information has the potential to be nothing short of revolutionary!  From this perspective, the liver can make a ‘hormone’ from fat that protects us from oxidative stress, inflammation, diabetes, and probably Alzheimer’s disease and aging as well (Roberts, 2017).   All we need do to accrue these benefits is restrict carbs to allow the keto-adaptation process to occur.  But to date, none of these beneficial epigenetic effects seem to include pathways that might make body fat melt away.
The popular "flat belly diets"embrace much of the wisdom found in eating a Mediterranean diet, which helps everything from brain health to hearth health. The basic premise for both diets is eat foods rich in monosaturated fatty acids (MUFA) that may help reduce your belly fat storage. MUFA-rich foods include olive oil, nuts and seeds, avocodos, and fish. Eating yogurt regularly has also been found to be helpful in reducing belly fat.
That’s because women tend to store more temporary fat in their bellies. “The fat stores are gained and lost,” says Lawrence Cheskin, MD, chair of the department of nutrition and food studies at George Mason University and director of the Johns Hopkins Weight Management Center. “By and large, belly fat comes off easier in the sense that it comes off first. That’s where a good amount of the fat is lost from.”

While it may seem like moderate intensity, commonly referred to as your "fat burning zone", is the optimal level of intensity for fat burn, total calorie burn skyrockets at high intensity and you may actually end up burning more fat overall. Some research even suggests short duration workouts at high intensity can burn as many calories as a much longer moderate training (7,8,9,10). Part of this is due to the after burn effects from increased metabolism that continues well after high intensity training.


“Most people who have been lean their whole lives have a much better understanding of proper portion size than people who are overweight,” says Deborah Riebe, Ph.D., a professor in the department of kinesiology at the University of Rhode Island. “If they go out to eat, they’re much more likely to ask for a doggie bag right away or to leave food on their plate rather than cleaning it up.”
If you aren't getting enough protein, and not strength training regularly, extremely restrictive diets may cause you to start burning more lean muscle for energy instead of fat (23). Why does this matter? You are losing precious muscle mass - which is key for keeping your metabolism intact and improves your overall quality of life.  In addition, reduced lean muscle mass increases your overall body fat percentage, even though the number on the scale is decreasing.

As you exercise, calories are burned and your body fat percentage decreases. So, exercising not only helps you lose belly fat, it also sheds fat from other areas. Running and walking are two of the best fat-burning exercises. Plus, the only equipment you need is a good pair of shoes. Between the two, running burns more calories, but walking really isn’t too far behind.

Fast forward several years later, I had another baby (Winter) and came out of that pregnancy about 40-50 lbs over my end goal weight. I had always had this dream to finally hit the big “100” in weight loss. By 2013 I had begun to take some classes at the gym and count calories a little more but I in NO WAY did anything extreme. And I honestly believe that is the key to weight loss and to keeping it off. It was NO quick journey to that final number but by July 2013, I hit 120 lbs and had officially lost 100 lbs…

An aerobic exercise routine can help you lose inner-thigh fat by burning away fat calories. The CDC recommends a minimum of 75 minutes of vigorous aerobic exercise or 150 minutes or moderate aerobic exercise each week for adults. Brisk walking, taking the stairs and raking leaves are some examples of moderate aerobic exercise. Vigorous aerobic activities include exercises like swimming, running and jumping rope. To start losing fat, you'll likely need to exceed the minimum recommendations.
●Put tempting foods out of sight, out of mind. We naturally gravitate toward foods that are easiest to reach. So put candy on a high shelf or inside another bag behind something else so you’ll be less likely to go get it, says Cynthia Sass, co-author of “The Flat Belly Diet!” Put smarter choices, such as fresh fruit or popcorn, in bowls where they’re visible and within arm’s reach. Keep a water bottle with you so you won’t have to rummage through the fridge or walk to a vending area to get a drink.
A review article published in the Journal of Obesity in 2011 notes that while there is some evidence for chitosan, Irvingia gabonensis, conjugated linoleic acid and pyruvate, there isn't yet enough evidence to say for sure that they're helpful for weight loss. The article notes that Garcinia cambogia and chia seeds don't appear to show promise as fat burners. The 2011 Obesity Reviews article notes that evidence is also lacking for the use of forskolin, fucoxanthin, kelp and chromium for weight loss.
About: Gina has the kind of success story that really touches a nerve. She started out at 298 pounds and went on to lose 168 of those pounds in 25 months. As someone who always struggled with her weight and achieved such a huge thing, she has an especially good grasp on how to help other people who have 100 or more pounds to lose achieve their goals. Her blog is a place she uses to motivate, inspire, energize and connect with others. And that’s exactly what it is.
How we are, depends a lot on the people we hang out with. To lose weight, you have to be around people with similar goals or people who have lost weight. This will inspire you and make you more aware of healthy habits. Gradually, you will incorporate those habits into your life. And I bet, you will wake up and be proud of how your thighs and your whole body looks.
The first couple of weeks of wanting to make a change were in a very busy season of life. The first two weeks of January were filled with healthy food and exercise, but as soon as classes started, the business really kicked in. There were weekly ministry activities, ultimate frisbee practice, classes, research projects, trying to hang out with friends before everyone moved across the country after graduation, etc. The busier my schedule was, the less important healthy eating and exercise became. It was only a few weeks and I fell of the bandwagon and was back to my old habits and feeling frustrated. I would tell myself “I’ll eat better tomorrow” or “I’ll work out tomorrow night” and then had such difficulty following through. I pushed it off and pushed it off.  I had some short streaks of eating well, but my lack of self-control would lead me to easily giving up. I made excuses for my unhealthy lifestyle like “I’ve always been overweight” or “I’ve never consistently worked out” because there were overweight people that loved themselves well too.

ANYWAY, as far as the beginning of college goes, I thought a lot about nutrition and fitness and really wanted them to be incorporated into my life. For exercise, I joined the women’s ultimate frisbee team.  I honestly joined because the team was a built in community of really amazing people who were great friends but even better accountability partners that kept me coming to practice and pushing myself while I was there. We had practice for 2 hours about 3 times a week, and I never exercised outside of those times. On the topic of nutrition, I never thought I ate that bad. However, college dining halls can wreck your body. Unlimited buffets with more unhealthy than healthy options was not in my favor. Of course I ate salads, chicken/fish, and veggies on a regular basis, but I also ate my fair share of french fries, frozen yogurt, cookies, and whatever desserts were available. So many weekly activities and meetings had free food, and late night study snacks were a regular occurrence.
Hi! I have to say 600 calories is terrible! You are going to starve your body. On average without exercise, your body burns at least 1400 calories, if you are eating only 600 calories you are not fueling your body with proper nutrition. When this happens your body goes into starvation mode and you end up gaining weight to, worse yet, end up sickly. Don’t do that to yourself, please! When I added more calories into my diet, I gradually added more, like a 200 a week. I gave myself an extra snack. I don’t recall if I gained weight at the beginning, but I do know I lost weight when I ate more. Don’t be afraid to eat!! What I would do if I were you is add more protein into your diet, like eggs, greek yogurt, lean chicken. You also need a little fat like avocado, olive oil or peanut butter. I personally found the hardest thing about dieting is not being able to stick to it. I dieted for 2 years lost weight, but then life happened. I eat healthy but what I started back when I was dieting I was eating low calorie, now I eat what normal people eat and I gained some weight back. But I realized what I was doing to my body back then, I wasn’t able to do that for the rest of my life. My advice is to eat healthy, eat what is in your calorie range and exercise for 30 minutes a day, even if it is just a walk. Doing this is a set-up for permanent weight lose and you will be healthy. I learned over the years that a healthy body on the inside, shows on the outside and even if you gain a little weight you are better off.

About: Kristen is a 42-year-old woman who a few years back decided she was going to lose weight — and she was going to do so by running and blogging about it.

Stand with feet hip-width apart and arms by your side. Make sure to focus on your posture—keep your chest up and spine straight. Then, take a large step forward with the left foot and sink into your lunge position until your left thigh and right shin are parallel to floor. Hold for three seconds and then lift up a bit for 30 seconds. Repeat: Lagree recommends doing three sets of 15 reps on each leg with short rests in between.
When Tufts University researchers studied the waistlines and diets of 459 people, they found that even in men of similar age and activity level, those who ate white bread frequently weighed more than those who didn’t. “The calories from white bread and refined grains just seem to settle at the waistline more than calories from other foods,” says Katherine Tucker, Ph.D., the study author.

Also, while your menstrual cycle may not affect weight gain or loss, losing or gaining weight can affect your menstrual cycle. Women who lose too much weight or lose weight too quickly may stop having a period, or have irregular periods. Women who have obesity may also have irregular periods. A regular period is a sign of good health. Reaching a healthy weight can help women who have irregular periods to have cycles that are more regular. Learn more in our Menstrual Cycle section.
But while many people want to target their belly fat, it's easier said than done. You can't spot-reduce fat from any specific place in your body. That's why endless crunches won't give you flat tummy. But you can lose weight overall, including from your belly, thanks to a combination of diet, exercise, and other lifestyle habits. Although every body is different and loses weight at a different speeds, personal trainer and dietitian Jim White, RD, ACSM, told POPSUGAR that you can see results in as little as two weeks.

Many people think that they can eat what they want if they take Lipitor. Lipitor doesn’t seem to take care of triglycerides. However, drop the junk foods, processed foods and stick with a plant based diet and you’ll see those triglyceride levels drop. So…. taking Lipitor but still eating whatever your sweet/ salty tooth desires, your triglycerides may still be high. Ouch!
About: Inspiring. That’s the first word that comes to mind when describing Gabby’s blog. Gabby used to tip the scales at 262 pounds and started a blog to chronicle her journey. Today, she weighs in at 140 pounds...in other words, half of her old self. But just because she dropped the pounds doesn’t mean she stopped being there for her readers. Thousands of articles and a whole lot of experience later, Gabby continues to share her weight loss wisdom and tons of healthy recipes with fans in an easy-to-follow — and often hilarious — way.
Sable of Squat Like a Lady is a self-described full-time student and part-time powerlifter, but she hasn't always been buff and tough. After suffering from anorexia as a teen, Sable gained 80 pounds. On her journey back to a healthy weight, she fell in love with heavy weight lifting. Now, her focus is no longer about losing weight—check out her post Don't Call Me Skinny! —but on gaining strength.

Your body is connected from head to toe. With that being said, make sure your musculature in the areas around your thighs are toned as well. For example, your abdominal muscles work to pull up your quadriceps in order to relieve the pressure on the knees. Your gluteal muscles help with stabilization of the hip joint and work together with the quadriceps to engage in numerous power movements.
