The most recent post, Beauty is Bone Deep, focused on women who try to force a thin physique on their (usually unwilling) bodies for the sake of an unrealistic beauty ideal. But there are those women, and men too, who try and try togain weight rather than lose it, often to no avail. These aren\u2019t people who have an eating disorder or anorexia \u2014 they\u2019re otherwise healthy-seeming people who simply can\u2019t gain a single pound.Table of ContentsToggleThe problem everyone wants \u2014 unless they have itRoot causes of being unable to gain weightSuggestions for those who aren\u2019t hungryIf anxiety or worry is prohibiting weight gainThe problem everyone wants \u2014 unless they have itNow, many folks out there will read this and think, \u201cGee, that\u2019s a problem I wish I had.\u201d But as people who do have this problem will tell them, the struggle to gain weight is actually harder than the struggle to lose it.Think about it: there are dozens, if not hundreds, of weight loss solutions out there (some better than others), but there aren\u2019t many workable solutions to gain weight in a healthy manner. If you search the internet, you\u2019ll find most information on weight gain is for bodybuilders and focuses on building bulky muscle, but that\u2019s not something most women (and many men, too) really want. And contrary to the suggestions some of my underweight clients hear, eating cheeseburgers, ice cream and cookies 24\/7 does not help, and it\u2019s a highly acidifying, bone-damaging way of life as well.So what should an underweight woman or man do to gain weight in a healthy manner?Root causes of being unable to gain weightJust as with any health issue, solving underweight requires examining root causes. I\u2019ve noticed that people who are underweight fall into several camps:There are those who tell me, \u201cI eat just fine, but I just never seem to put on any weight.\u201dOthers say they simply don\u2019t get hungry or don\u2019t feel like eating, so they skip meals. Sometimes, these people say that eating makes them feel sick, so they eat less (or less often) as a result.Some say they eat well some of the time, but that they eat less when they\u2019re under stress \u2014 and they\u2019re under stress often.For people who stay thin despite eating well, I look at three factors. First, are theyreally eating enough food on a regular basis, or is that simply their perception? Is a meal something they sit down to at a table, with 2 or 3 different dishes, and spend time enjoying \u2014 or do they consider an apple and a small tub of yogurt consumed between meetings at work to be \u201clunch\u201d? While the average adult needs 2000-2500 calories, that\u2019s an average; some people require more, but may not realize it \u2014 and gaining weight might simply be a matter of eating more nutrient-dense foods. Moreover, if you\u2019re underweight because of a nutritional deficit, you may need to supplement with the 20 key nutrients required for bone health because if your muscles, skin, organs and tissues aren\u2019t getting what they need, they\u2019ll take it from your bones!Second, I consider whether a metabolic or endocrine issue could be at work. Hyperthyroidism, latent autoimmune diabetes in adults, and various other chronic disorders can prevent people from gaining weight, even when they eat well \u2014 and sometimes, these disorders are \u201csilent,\u201d meaning they have no clear-cut symptoms. I often recommend a medical workup for osteoporosis for this very reason. Simple blood tests can generally uncover the presence of autoantibodies or hormone imbalances, however. Such disorders represent significant health issues that need to be addressed by a specialist.Finally, I\u2019d look at the possibility that they might not be absorbing the food they eat. A great many malabsorption syndromes and digestive issues can prevent a person who eats reasonably well from reaping the benefits of the food they take in. Some of these, like IBS or Crohn\u2019s disease, have obvious symptoms attached \u2014 diarrhea, gas, bloating, pain \u2014 but others, such as celiac disease, can damage the GI tract and impair nutrient absorption capabilities, sometimes without causing any distinct symptoms related to the digestion. Poor nutrient absorption frequently occurs in older people simply as a byproduct of aging. So if I saw indications of poor nutrient absorption (dry, brittle hair and nails, for instance), I might suggest that a client ask her physician for testing for celiac or other GI issues, and we\u2019d look very closely at how to boost the nutritional and caloric content of her food so she gets more of what she needs. And I\u2019d offer them suggestions for how to strengthen their digestion.Suggestions for those who aren\u2019t hungryThose who don\u2019t feel hungry or who don\u2019t feel like eating usually have one of two problems. Either they have an imbalance in the \u201chunger hormones\u201d that stimulate appetite (often associated with zinc inadequacy), or they simply don\u2019t prioritize meals sufficiently. The second problem is likely more common than the first \u2014 many folks are so rushed or busy that they habitually ignore their body\u2019s signals that it needs food, to the point that they genuinely believe they\u2019re not hungry even when they are! These folks benefit by taking time to acknowledge and understand their physiologic needs. I would do the following:Review their diets to make sure they are getting a full balance of fats, carbohydrates, and proteinsHelp them schedule their mealtimes, including time for pre-meal \u201cappetizer\u201d foods such as broth (warm liquids stimulate the appetite).Suggest an elimination diet or allergy testing for those who say they feel ill or uncomfortable after eating.If anxiety or worry is prohibiting weight gainFor those who stop eating or eat less due to anxiety or stress, part of the problem is their response to anxiety and worry. For clients whose thinness is related to an anxious mind, I\u2019d help them to learn stress-reduction techniques, and also have them focus on their intentions around eating \u2014 that is, to find ways to celebrate their meals as an affirmation of their worth. It doesn\u2019t need to be complicated \u2014 simply saying grace before each meal, for example, can send a strong signal from the mind and spirit to the body that the food in front of you is a blessing meant to nourish you. The power of the mind should not be underestimated, and focusing it on nourishment (instead of on anxieties and worries) may be an important component of promoting healthy weight gain.If you\u2019re underweight, taking steps to build strong muscles, eat a nutritious diet, and reduce stress and anxiety can help you gain weight, meanwhile reducing your fracture risk. Even if the tips outlined above don\u2019t help you to add a single pound of weight, the bone-strengthening benefits of my Better Bones approach may make the difference in staying healthy and avoiding fractures \u2014 and isn\u2019t that what matters in the long run?For a complete breakdown of the most effective options, see our guide to the best supplements for bone health."},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Bone Nutrition","item":"https:\/\/betterbones.com\/bone-nutrition\/#breadcrumbitem"},{"@type":"ListItem","position":2,"name":"Nutrition for bone health \u2014 how to gain weight if you\u2019re too thin","item":"https:\/\/betterbones.com\/bone-nutrition\/weight-gaining-for-under-weight\/#breadcrumbitem"}]}]
