Weight loss can be intentional, such as from dieting and exercise, or unintentional and be a manifestation of illness. Weight loss can result from a decrease in body fluid, muscle mass, or fat. A decrease in body fluid can come from medications, fluid loss, lack of fluid intake, or illnesses such as diabetes. A decrease in body fat can be intentionally caused by exercise and dieting, such as for overweight or obesity. Weight loss is normal after pregnancy. Other causes of weight loss include, but are not limited to, cancer, viral infection (such as CMV or HIV), gastroenteritis, parasite infection, depression, bowel diseases, and overactive thyroid (hyperthyroidism).
Electrolytes play a major role in keeping us alive since they provide the electrical current that allows our muscles, particularly the heart, to contract at the right speed. When there is a sudden decrease of food intake, there is also a sudden decrease in the electrolytes that our bodies are used to getting, particularly potassium and magnesium. If the body can’t handle the deficit, this can lead to impaired cardiovascular function and irregularities such as heart arrhythmias.
About: Sara, a new mom, is all about living a happy, healthy and fun life. She’s struggled with her weight for years, and, as she puts it, can’t wait for the day when weight no longer gets in her way. Sara’s biggest appeal is that she’s all about using good ole fashioned weight loss techniques — eating healthy and exercising. And that philosophy permeates through her blog, inspiring readers and engaging fans along the way.
Hey Adam! I’ve gained almost 30lbs in the last year. My motivation for any athletic anything has tanked. I travel 100% of the time only home on weekends. It makes any routine for healthy eating difficult. If I’m lucky I have a small fridge and microwave in my room…fridge is most common. I am a huge snacker. I’ve gotten better. I snack on tricuits, and special K chips and granola/cereal bars, apples with peanut butter, etc… I drink wine or beer every day but would be the easier of the two to give up (snacking or alcohol).

Do it better: Short bursts of intense activity burn more calories—and up to 36% more fat, according to a study published in the Journal of Applied Physiology. Strolling around the mall or a park for an hour works off about 150 calories; pick up the pace 1 minute out of every 5 to burn over one-third more calories (try a similar method if you bike). Swimmers can switch from freestyle or breaststroke to a more challenging crawl every few laps, or just go a little faster. Give these quick calorie-burning interval workouts a try.
If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.

About: Jade’s 6+ years of experience blogging means, at first glance, we would have passed right over her for this list. But it’s her recent debut into weight loss and healthy living blogging that caught our eye. Jade lives in Singapore, and just looking at Jade’s photos, it’s hard to imagine her as ever being overweight. But in 2012, she was unhappy with the way she looked, a feeling she’d had her whole life. Then the thought occurred to her that she had the power to change it. A total lifestyle overhaul and 44 pounds later, and Jade’s story is a success we can all admire.

Part of slimming down involves a simple, sensible exercise and an easy-to-follow nutrition plan. This full week of meals will take the guesswork out of grocery shopping and prepping with nutritionist-approved breakfast, lunch, and dinner ideas. If you have a higher activity level, check out these 1,300-, 1,400-, 1,500-, and 1,800-calorie meal plans as well.


Only 11% of Americans correctly estimate their ideal daily calorie requirements, according to one survey. The rest of us tend to overestimate, says Bonnie Taub-Dix, RD, a spokesperson for the Academy of Nutrition and Dietetics. Let's say you assume that consuming 2,000 calories per day will allow you to reach your target weight, but it really takes 1,800: Those extra 200 are enough to keep an additional 20 pounds on your frame. 
Hi. I weigh 220 and am 5’8’’. I’m obviously overweight but I’m not in terrible shape, I play sports twice a week and try to run one or two times a week also. I have a 5K coming up in 2 weeks and I plan to do an event on June 1 where I need to be 210 pounds. I don’t want to stop at 210, I want to be back under 200 again. I don’t think I eat terrible, I eat granola in the morning and lunch during the week and try not to go nuts at nighttime. My vice is beer on the weekends, I am not an alcoholic but I can easily put back a six-pack if I wanted to on a Friday or Saturday night when hanging out with friends. Other than the beer, I only drink water, green tea, and coffee – no sodas or sugary drinks.

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.


If you’re allergic or sensitive to a certain ingredient and continue eating it, you’re likely to struggle with losing weight. The food is triggers inflammation, as your body fights against it. As you continue eating the same food that’s making you ill, the inflammation continues, making you a lot more susceptible to extra pounds and other health issues.
I’m 5′ 2″ or so, and about 102 pounds. I’m 19. Not that long ago, I was only 94 or so, and I eat very healthy (lean protein, fruits, vegetables). My one “no-no” is Starbucks in the morning, but I’ve always done that, even when I was thin. I want to drop the 8 pounds I gained ASAP. I used to be very tone, and I feel like all that has gone away. What do I need to do. Please help.
“It’s far more difficult to eat a healthier diet and fit in exercise if you don’t plan ahead. Plan out your meals for the week ahead and go grocery shopping over the weekend to ensure you have the ingredients you need on hand. If you can, do some meal prep in your downtime—cut fresh veggies, marinate your protein, cook up a batch of whole grains in advance. When you’re prepared you’re far less likely to order takeout. — Jessica Fishman Levinson, MS, RDN, CDN, culinary-nutrition consultant and founder of Nutritioulicious

●Halt bad eating habits. Before you cave to the crave, hit the pause button, recommends Pamela Peeke, author of the bestseller “The Hunger Fix: The Three Stage Detox and Recovery Plan for Overeating and Food Addiction.” Ask yourself: “Am I hungry? Angry? Anxious? Lonely? Tired?” Get in touch with your emotions and ask, “Am I’m emotional right now? Am I about to knee-jerk into overeating?”
Some antidepressant medications can cause weight gain, especially the older tricyclic antidepressants (TCAs) such as Tryptizol, Saroten, and Clomipramine; as well as newer drugs such as Remeron (Mirtazapine). Lithium (for manic-depressive disorder) often causes weight gain. The most common antidepressants known as SSRI’s (for example Citalopram and Sertraline) usually don’t impact weight significantly. More on depression
More importantly, though, strength training does wonders for your body. It helps make bones denser, critical because our bones become weaker as we age, increasing the risk of osteoporosis — of the 10 million Americans suffering from the disease, 80 percent are women. (4) Strength training helps build lean muscle tissue, helping you lose more weight all over, including the dreaded belly fat. It also reduces your risk of type 2 diabetes and cardiovascular disease.

Satisfying your sweet tooth doesn't require a refined sugar-packed snack. The key is retraining your taste buds to recognize naturally sweet foods, like fruit. "To curb my hankering for treats, I eat mangoes," says Tamyala Ezell, who lost 105 pounds by making over her eating habits and working out three times a week. "They have a natural sweetness that does the trick. Plus, they're low in calories and high in fiber." Another example? "I top berries, nectarines, and cherries with homemade whipped cream, nuts, and dark chocolate," says Goetke.
Rise and shine—literally! Researchers from Northwestern University found that people who were exposed to bright daylight earlier in the day tended to weigh less than those who didn’t get sunlight until later. So right after you wake up, open the blinds and let the sunshine in. Or better yet, step outside and enjoy your morning cup of coffee on the front porch
Thanks for sharing Brittany! I love your honesty and could not have used this post more today. I have been struggling with weight gain the last couple of years and keep falling into this loop hole of not eating clean. I work out 5 days a week, however my diet has not changed and so I have struggled. I will be definitely looking into this book as well to give me a new outlook and starting point. Kudos to you to maintaining a busy life of family, running a business and healthy lifestyle. I am inspired that if someone like you can make the change anyone can! Hugs
Say cheese! Adding some extra calcium to your diet could be the key to getting that flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.
About: Amy started her weight loss journey after she ran the Disney Princess Half Marathon at her heaviest weight ever — and realized it was time to make a change. Fast forward a couple years, she's lost 65 pounds, motivated especially by her father, who she calls her “biggest cheerleader.” Then her father passed away, and things went downhill a bit. Amy gained 40 pounds back and in 2014 started a weight loss blog to embark on the ultimate quest: signing up for races (her most recent was the Star Wars Half Marathon) and letting readers know that she feels their pain — and, most importantly, that they can get through it and make the changes and run races, just like she is.

Christina Russell is a Celebrity Trainer, author, and the writer behind the healthy living blog, Body Rebooted. Christina lost over 60 pounds in just 5 months incorporating a gluten-free diet and fitness routine and created her blog as a place to share her gluten-free recipes along with the ins and outs of her weight loss journey. Her blog has since evolved into a full-blown healthy living website that provides resources for you to reach your goals.
Stop drinking sugary liquids. Sip on water, tea, black coffee or seltzer instead of soft drinks, juice energy drinks, flavored coffees, and martinis. Cutting calories with substitutions can be a lot easier than you might think. For example, a tall latte in the morning may pack 500 calories. Since a pound of body fat (lost or gained) is roughly equivalent to 3,500 calories, replacing that rich beverage with black coffee can help you lose a pound per week.[9]
Consistent with the current study, recent findings indicate that slow weight loss, as recommended by current guidelines, worldwide, is not a priority over rapid weight loss. Purcell et al. in a clinical trial studied the effect of weight loss rate and weight management. Their results showed that in the long-term, with rapid weight loss (450 to 800 Kcal/day) than gradual weight loss (500 kcal less than the daily requirement), the weight loss is faster and more stable. The researchers suggested that the limited carbohydrate intake of very-low-calorie diets might promote greater satiety and less food intake by inducing ketosis. Losing weight quickly may also motivate participants to persist with their diet and achieve better results (29).

How would you like to take all the great weight-loss results you’ve just read about—and double them? That’s what happens when you supplement your diet with a combination of vitamin D and calcium, according to a Nutrition Journal study. Just four weeks into the 12-week experiment, subjects who had taken these two nutrients—found in abundance in some yogurts—lost two times more fat than the other group! To get similar results at home, start your day with one of these best yogurts for weight loss.


Very low levels of thyroid hormone usually indicate an autoimmune reaction to the thyroid gland itself. This means you’ll have to take thyroid hormone supplements orally, usually the stable form T4 (Levaxin), which your doctor can prescribe for you. Your body will transform this into the active T3 hormone when necessary. The supplement dose should be adjusted so that you reach normal hormone levels (TSH, T3, T4) and sufficiently alleviate symptoms – though a few people feel best when keeping TSH slightly below normal.
Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
Wheatgrass has a high concentration of iron, magnesium, calcium, amino acids, vitamins C, A and E, B12, B6 and chlorophyll. These vitamins and minerals provide many therapeutic benefits. Consuming wheatgrass can rid the digestive system of harmful bacteria and cleanse the body of toxins. It also cleanses the colon and can help in the treatment of joint pain, ulcerative colitis, skin infections and can even prevent diabetes.
Skimp on fluids, and your body will release an antidiuretic hormone that leads to water retention that could affect the scale, Dr. Setlzer says. While this sneaky effect is one reason why the scale is a poor measure of body mass loss, you can outsmart it by drinking more—particularly if you fill your glass with water or non-calorie alternatives like unsweetened coffee and tea.

About: Sanji started her blog in 2009 as a personal journey to discover what adventures life would bring her, including religion, dating, traveling and more. Fast forward 7 years later, and Sanji is married and has a child. Recently, she morphed her blog into a place to share about her weight loss journey and efforts to live healthy. Add in her long-time writing experience and willingness to get vulnerable, and you’re sure to find it’s a journey you can relate to and find inspiration.

Then, there’s biochemistry. In women, ghrelin — the “I’m hungry” hormone — spikes after a workout, while leptin — which tells the brain ‘I’m full!’ — plummets, according to a 2009 study in the American Journal of Physiology — Regulatory, Integral and Comparable Physiology. Not so in men. So post-workout, women tend to eat more, which puts them at risk to gain weight. Men don’t experience this same hormonal fluctuation.


Oh and Sara and I actually connected thanks to Pinterest! She had seen one of my posts on Pinterest and when she saw my website and read my weight loss journey, she saw that we had a lot in common. We emailed a bit, then talked on the phone, and we clicked instantly. It was, without a doubt, a God-led meeting and we have both been so blessed by every part of our friendship and business partnership!
‘Lastly, if your nutrition is on point but you still have excess tummy fat, then you need to look at your training. There’s a real craze for high-intensity workouts and really pushing yourself at the moment, but training is a stress on the body, and if you’re not giving it the tools to manage that stress and recover from it, then it can lead things like excess belly fat.
There is plenty that you can do to get even more out of your walks. Stephanie Cyr began her 102-pound weight loss journey by walking for an hour each night—but there was a catch. "I mapped out a 3-mile course that took me through the hills in my neighborhood," she says. Live in a flat area? Alternate 1 minute of super-fast walking with 1 minute of slower walking for a calorie-torching interval routine.
About: The first thing you’ll notice when you check out Adam’s blog is that he’s funny — like really, really funny (hence the name of his blog). A self-proclaimed “boring guy” and “dork,” Adam’s blog started as a way to share his thoughts on being a traveling management consultant to a place for sharing running, humor, life and more — probably one of the most interesting changes we’ve run across. Adam’s been battling some knee problems off-and-on, but still makes it a priority to live healthy, exercise (like hiking) and share it all in his traditional good-humored, naturally-engaging way.
I played tennis from my freshman through junior year of high school and, again, really enjoyed the sport, but abhorred the running.  Our coach was a middle-aged guy who could run circles around me.  The entire team would have finished their laps around the field, while I was still stumbling along next to the (also middle-aged) assistant coach, who I’m quite sure they sent in as an attempt to get me to run faster.
I am 29 years old and weight 149.80 lbs. I weighed 190 almost two years ago. I have been struggling trying to lose the last 25 lbs to reach my goal. My biggest problem is that I lose almost all of the weight from my upper body but none of the fat has budged from my under arm (jiggly arms), inner thighs, knees or calves. I’m at a lose as what to do now.

A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
I would love to try this diet out since I will be going to the beach with a large sum of people in exactly 13 days, but one problem, i do not eat meat or fish. I do however consume beans and vegetables and i’m at the gym for two hours a day monday- friday . But for the past few months, I’ve only lost five pounds. I use to weigh 133, now i weigh 128. By the time we get to the beach i want a smaller stomach and hopefully smaller thighs and my goal weight is 118.
I’ve been doing carb free for the last two weeks with one cheat meal per week. I did this same “diet” in high school and lost 48 pounds in 2 months (all while attending keg parties on the weekend, those were the days!) I’m not suceeding (thus far) as much as I had back then, despite being more regimented. Could this be because it’s a decade and a child later? I’ve heard your metabolism can change after childbirth. After reading through your postings I think some of my issue might be the amount of fruit I’m eating.. i:e Bananas in the morning and an afternoon snack of apples and peanut butter. Maybe I’m snacking too much on cheese? Oh I’m just so frustrated. I’m hoping after this week, now that I’m over being sick and can integrate cardio that the fat burn will pick up, but for now I’m super discouraged.
About: If the title alone doesn’t draw you in, we don’t know what will. Start with Mariana’s “About the Fluff” section, and by then you’re for sure hooked. Mariana is a Puerto Rican on a journey to get rid of everything that weighs her down, whether that’s extra pounds, distractions from living a healthy life, unhealthy relationships, stress, you name it. Her blog is a day-by-day, step-by-step process that blends humor with reality in a way you’re darn sure going to understand if you’ve ever struggled with weight.
Your body stores up fat for later, but if you eat a balanced amount of healthy fats your body will stop storing it because it knows you will be having it everyday. Kind of like that age old diet tip, don’t put yourself into starvation mode, it will make your body hold onto fat for later, same is true here. Feed your body healthy fats and it will release excess fat from your body.
A little garlic in your meals could mean a lot less weight around your middle. The results of a Korean study found that mice given a high-fat diet supplemented with garlic lost significantly more weight and abdominal fat than those who just ate fatty foods. Even better, they also improved their liver health, making it easier to stay healthy and burn off that excess fat in the long term. For more flavorful ways to make your food more enjoyable, turn to the 20 Spicy Recipes That Fire Up Your Metabolism and watch those pounds melt away.
"I use low-fat Greek yogurt in place of mayo in recipes, and it tastes great," says Krystal Sanders, who went from 185 pounds to 110 by coming up with healthy versions of her favorite restaurant foods. "It can also be used as a sour cream substitute." The possibilities are endless when it comes to this tasty staple, but you can start with these dessert recipes.
