My wife is super skinny?

Yeah, so your wife is actually very scary skinny, since what I calculated, her bmi lands around 14,9 which is clearly underweight for a woman at her height.

She needs to eat more often and bigger portions. Don't over exaggerate in the beginning, start slowly and build up on more for every week.

But before you guys decide on anything, go through what can have caused her weight loss. Does she suffer from any diseases, like bulimia or anything else? Or is she on medication that can cause weight loss? Or does she train too hard and eat too little? Or is she one of those who has a really quick metabolism?

And has she always been skinny, or when did she start to loose weight?

I would advice that you go to see a doctor with her in either cases. because this process can be long and tough for her and she might need more help. Your job is to support her and be there by her side and cheer on her. Don't give up!

And always, tell her that she is the most gorgeous woman and that you believe in her.

Encourage her to eat well balanced meals of proteins, natural fats, and good carbohydrates like veggies, berries, and fruit.

She needs to restrict cardio exercise when trying to gain weight.

why is she that low in weight? has she been deliberately eating less and losing weight? Does she have a medical problem, illness or disease?

1. Don’t let more than four hours go by without eating. Your body needs a continuous supply of energy since it’s like an engine that’s always turned on (your heart is always beating, blood is circulating, your brain and muscles are working). When you skip meals, you deprive your body of the fuel it needs to keep going. The result is a dip into your energy piggy bank, which unfortunately includes muscle mass. The best way to prevent your body from losing any important tissue is to eat regular meals, spaced about three to five hours apart. If you’re trying to gain new muscle tissue, meal timing is especially critical. Sometimes my clients tell me they “eat all the time” but when they actually start keeping a food journal they realize just how erratic their patterns are. Consistency is key.

2. Eat several foods at once. Always aim for at least three food groups. Instead of just a banana or handful of nuts, top a few slices of whole grain toast with almond butter and banana slices, along with a glass of organic skim milk or a milk substitute (soy, hemp, etc.). A wider varied provides your body with a broader spectrum of nutrients to work with throughout the day.

3. Eat healthy, but dense foods. The best way to rack up extra nutrition without having to eat huge quantities of food or resort to junk is to choose nutrient-rich foods that pack a lot of carbohydrates, protein or fat into a small serving. Dried fruit is a great example. With the water removed, the portion shrinks by about 75 percent, so a cup of grapes turns into a quarter cup of raisins. Just be sure to look for dried fruits with no added sugar or preservatives. For another nourishing, power-packed snack, fold rolled oats, dark chocolate chips and minced dried fruit into almond butter – spoon out portions about the diameter of a quarter, roll them into little balls, wrap in wax and paper, and snack on them throughout the day.

4. Drink your food. Liquids aren't as filling as solid food, so when you’re trying to gain weight, they can add nutrition without making you feel stuffed or bloated. Good choices include 100 percent fruit juice, organic skim milk or milk alternatives (such as organic soy, or hemp), and smoothies. Smoothies are ideal (over milkshakes) because you can bolster them with all kinds of good stuff, like wheat germ, nut butter, carrot juice, and protein powder.

5. Eat right before bed. A lot of our healing, repair and regeneration takes place while we sleep. It’s like rush hour for building muscle and lean tissue, so eating a healthy snack right before bed ensures a fresh supply of nutrients that are available to “go to work” inside the body. A great option that won't leave you feeling stuffed might be a small bowl of pasta salad made with 100 percent whole-grain pasta (wheat or a gluten-free alternative), vinaigrette made with extra-virgin olive oil, chopped or shredded veggies, and a lean protein such as beans, chopped chicken breast or an organic crumbled cheese.
