Want to Lose Weight? Add Calcium, Vitamin D Combo to Your Diet!

The “milk builds strong bones” mantra was drilled our heads as kids, but this essential mineral isn’t just for building strong, healthy bones — studies suggest that calcium could be another weapon against body fat.

BUT before you start chugging a gallon of milk every day, just know that calcium won’t magically melt away the weight you want to lose. But it does play a key role in a bunch of bodily processes, so it’s an important part of a healthy, balanced diet, which is important when your goals are to drop fat, lose weight, and get healthy.

Why Do You Need Calcium?

Calcium is a macromineral because we need it in such large amounts — the recommended daily allowance is around 1,000 milligrams for adult men and women, and bumps up to at least 1,200 milligrams as we age.

The large majority (around 99 percent) of calcium is stored in our bones and teeth; the rest is found elsewhere in our bodies (blood, muscle, tissues, etc.) helping our blood vessels and muscles function, nerves fire smoothly, and encouraging the proper secretion of hormones, among other tasks.

Are You Getting Enough Calcium?

The problem with this essential mineral is that there’s more than even money that you are not getting enough calcium in your daily diet. According to the National Institutes for Health, several groups of Americans do not meet the recommended daily intake for calcium, specifically boys and girls ages 9-18, women older than 50, and men older than 70.

A study in the Journal of American College of Nutrition suggests that pattern may be influenced by the fact that we stop drinking as much milk as we transition out of our school years, and some of us become lactose-intolerant as we age.

Fortunately for the lactose-intolerant, or those of us that just don’t care for the white stuff, there are a lot of whole-food sources of calcium out there. Americans get about 72 percent of their calcium from milk and other dairy products, but other foods that are high in calcium include tofu, sardines, sesame seeds, dark leafy greens, and spinach.

Calcium May Help Reduce Body Fat… If You’re Deficient

So what’s the deal with calcium and weight loss? There are a few studies out there that show some kind of link between calcium and fat loss — with caveats, of course.

A small study found that obese women participating in a weight loss program who were calcium deficient lost more than 13 pounds after taking daily calcium supplements, compared to the control group, which lost a little over two pounds in the control group.

A review of studies on the link between dietary calcium intake and body weight suggests that calcium seems to bind more fatty acids in the intestines, thereby inhibiting the absorption of some fats. The review concluded that “calcium and dairy food intake can influence many components of energy and fat balance.”

Another small study showed subjects who consumed three servings of yogurt daily as part of a reduced-calorie diet lost more weight than those who simply cut calories alone. The yogurt eaters consumed around 1,100 milligrams of calcium daily. The non-yogurt eaters consumed about 500 milligrams of calcium a day (the average amount in the typical American’s diet).

The yogurt eaters lost 22 percent more weight, 61 percent more body fat, and 81 percent more abdominal fat than the non-yogurt eaters. As with the most recent study, the researchers hypothesized that the extra calcium provided by yogurt played a role in increasing the amount of weight lost during the study period.

So while there is some limited data to support the theory that calcium may play a role in weight control and weight loss, more research still needs to be done.

The Source of Calcium Counts

Another question that still needs further investigation is the source of calcium and why it’s important. Most of the studies investigating calcium’s role in regard to losing weight used dairy-sourced calcium.

“Dairy for some reason, yet unexplained, has a greater effect on fat loss and specifically trunk fat loss than does calcium alone,” says Rachel Novotny, PhD, RD, professor and chair of the department of human nutrition, food, and animal sciences at the University of Hawaii.

Researchers believe that there are various potential mechanisms that may explain those additional benefits. For example, some of the minerals in dairy foods, such as phosphorous and magnesium, may enhance calcium’s beneficial effects on fat breakdown within cells.

So far, the research doesn’t address whether there are possible weight-loss benefits of calcium from sources other than dairy, or whether you can simply take a non-dairy-sourced calcium supplement, such as calcium lactate or gluconate.

Diet Plan:

A balanced vegan diet will ensure you receive your recommended daily allowance. But more than just the total calcium you consume is important. Absorption is vital too.

Some foods, such as spinach, contain a high amount of calcium but is bound to a substance called “oxalate and that inhibits calcium absorption. While the pros outweigh the cons when it comes to spinach and health, you can still replace spinach with low-oxalate vegetables such as cabbage and kale. These options will do more for your bone health.

You really do have many sources and options of calcium containing foods.

In the “edible list” you will find:

  • Black eyed peas
  • Sesame seeds
  • Kale
  • Turnip greens
  • Seaweed (like wakame)
  • White beans
  • Firm tofu
  • Okra

For something to drink:

  • Organic soy milk
  • Almond milk
  • Cashew milk
  • Blackstrap molasses
  • Fortified orange juice.

All of these provide your body with healthy amounts of calcium. So let’s break them down and see just how much calcium you get with each…

Calcium Food Sources

Let’s look at a simple chart(1) of some of the top rich calcium sources you can add to your food plan.  Ensure you get the calcium you need in the most vegan-friendly form.

Calcium Content of Selected Vegan Foods
 Blackstrap molasses, 2 tbsp.  400 mg
 Collard greens, cooked, 1 cup  357 mg
 Other plant milks, calcium-fortified, 8 ounces  300-500 mg
 Tofu, processed with calcium sulfate, 4 ounces  200-420 mg
 Calcium-fortified orange juice, 8 ounces  350 mg
 Soy or rice milk, calcium-fortified, plain, 8 ounces  200-300 mg
 Commercial soy yogurt, plain, 6 ounces  300 mg
 Turnip greens, cooked, 1 cup  249 mg
 Tofu, processed with nigari, 4 ounces  130-400 mg
 Tempeh, 1 cup  184 mg
 Kale, cooked, 1 cup  179 mg
 Soybeans, cooked, 1 cup  175 mg
 Bok choy, cooked, 1 cup  158 mg
 Mustard greens, cooked, 1 cup  152 mg
 Okra, cooked, 1 cup  135 mg
 Tahini, 2 tbsp.  128 mg
 Navy beans, cooked, 1 cup  126 mg
 Almond butter, 2 tbsp.  111 mg
 Almonds, whole, 1/4 cup  94 mg
 Broccoli, cooked, 1 cup  62 mg


* Soy: There has been some confusion about soy and its effects on health. To clear up that confusion go to,

* Calcium Fortified: Unfortunately, you can’t rely upon juices and milks fortified with calcium. 

In addition to these calcium containing foods, it’s also important to reach your nutrient requirements for other bone healthy vitamins and minerals such as magnesium, vitamin D3, K2, C and adequate protein intake. Following a balanced, whole food diet is a great way to ensure your body is getting the basics. To make up for the shortfall, you can supplement with a clinically supported, multi-bone nutrient supplement.

Daily Meal Plan

Stuck for a daily meal plan?

Here’s a simple one you can use (or adjust with the ingredients above) for you own personal plan:


Make two servings of oatmeal in 1 cup of almond milk. Top with fresh fruit and a teaspoon of chia seeds. (Chia seeds contain 177 mg of calcium per one ounce!)


Make a delicious roasted beet and kale salad. Top with chopped almonds, sesame, pumpkin and sunflower seeds. For the dressing: mix together two parts olive oil to one part freshly squeezed lemon juice (with salt and pepper to taste).


Roast sweet potatoes in the oven and stuff with navy beans and sauteed mustard greens.


Spread two tablespoons of tahini onto two rice cakes.

Calcium Supplements

Obviously, for those of us who can consume dairy without any issues, including milk, cheeses, and yogurt in our diets is a viable option. However, for many others, that simply isn’t a possibility. In fact, for many of those who can’t safely consume dairy products, a simpler alternative could ensure adequate daily intakes.

One viable option is taking calcium supplements, and there are literally hundreds of calcium supplements on the market from which to choose. Many of them are excellent choices for meeting your calcium needs.

The Bottom Line

While the jury is still out on whether it’s a viable weight-loss tool, there are plenty of other reasons why calcium is an important part of a healthy eating plan. Most of the evidence shows that we should all be getting more calcium in our diet, period. So drink your milk and/or get more leafy greens and other calcium-rich foods into your diet for strong bones and a healthy body.

The “milk builds strong bones” mantra was drilled our heads as kids, but this essential mineral isn’t just for building strong, healthy bones — studies suggest that calcium could be another weapon against body fat.
