Protein intake requirements change over time following weight loss surgery. This is based on the requirements imposed on our body by a number of variables. These include, activity level, muscle mass, over all health condition to name a few.
A very young muscular athletic male with a BMI or 30 will require much higher protein intake (and absorption) that an inactive older Female with the same BMI. The same young athletic male will require much higher protein intake is he is recovering from a surgery than his baseline.
As we have stated in the past, the protein intake, should be adequate and not excessive. High level of protein intake that are not accounted for based on muscle mass and activity level, will eventually result in weight gain. The best measure of protein intake in a stable weight patient over 3-4 years post op is their albumin and protein level. Following your yearly laboratory values at a minimum is an important part of weight loss surgery follow up care.
You also need to adjust protein intake when necessary. Protein needs increase depending on physical needs, infection, healing, pregnancy, surgery, age, injury, etc. Plastic surgery requires higher protein needs for appropriate healing.

The basic formula for protein intake is 1gm/kg of ideal body weight. The calculator below will provide a guide for the protein into based on your stable weight in lbs.
Osteoporosis Medications, Action and Side Effects

Treatment options should be approached is a global and systemic fashion. It is critical that the nutritional status is at its best possible and optimized for important healthy bone vitamins and minerals. Low protein needs to be corrected. Special attention should be given to nutrients, minerals and vitamins. These include Protein, Calcium, Magnesium, Vitamin D, and Vitamin K1/K2to name a few.
Healthy bones require ongoing and routine force in the form of exercise to remain health. Just as exercise improves muscle strength, it also improves bone health. Exercise is also critical in improving bone structure and density. Ideally, exercise should be weight bearing and resistance. Examples include: hiking, walking, jogging, climbing stairs, playing tennis, and dancing. Resistance type exercise is weight lifting and resistance bands. These exercise work by creating a pull or force on the bone either by gravity, movement or weight. Always check with your physician before beginning an exercise routine, start slowly and building up to longer periods of time. The ideal goal would be at least 30 minutes a day, every day, if you are able.
We frequently see patients immediately started on osteoporosis medications without checking or improving some of the nutritional markers noted above or without looking at exercise history. In some case, the medication recommended are contraindicated due to nutritional status.
The medications can be grouped in to those that help with new bone formation (Anabolic agents) or those that help by suppressing the bone breakdown phase (Antiresorptive agents).
National Osteoporosis Foundation has an exhaustive list (below) of medications for treatment of Osteoporosis.
The table below outlines the side effects and mechanism of the actions of the common medications used for treatment of osteoporosis which was published by the University Health News Publication on August of 2014.
With all this information, the few points to remember is that the most important factors in healthy bone structure are the nutritional status Protein, Calcium, Magnesium, Vitamin D, and Vitamin K1 levels.
This is an animation of normal bone Metabolism. It shows how bone structures is taken down and rebuilt continuously. This allows for a healthy bone maintainence as we age. The key is the balance of breakdown (osteoclast) and the build up (osteoblast) activity is regulated. Osteoporosis develops when there is more breakdown that build up.

Not all proteins are created equally. The protein that we digest serves as the source of the essential amino acids, (the building blocks which make up a protein). The essential amino acids can not be made in out body. Protein sources can be animal or plant based. We’ve written a in-depth explanation of protein sources in this previous blog: Protein Optimization
The proteins can also be decided into two categories:
1-High quality or Complete proteins
Complete proteins contain all the indispensable amino acids that we need. Animal based proteins for the most part are complete proteins. These include cheese, mean, fish, mild, yogurt, egg and poetry.
2-Low quality or Incomplete proteins
Incomplete protein are mostly plant based proteins. In most cases, the incomplete proteins either lack or have insufficient about of the one or a number of amino acids to be able to satisfy our nutritional requirements.
This is why we general recommend animal based proteins.
Following weight loss surgery there are some guidelines that can be helpful in our previous blog: Importance of Protein.
There is also much discussion on whey protein. There is a brief and good explanation on this subject here.
Calcium Lab Results
June 05, 2018 3:26 pm
Calcium is measured to evaluate function and adequacy of a physiologic processes. Calcium plays a critical role in several body functions such as, coagulation pathways, bone health, nerve conduction, and other functions. It is important whenever you are evaluating laboratory results that you look at the whole picture of the person, including medications, other laboratory studies and health history. One value is not a stand alone result. There are many factors that effect calcium results.
Factors that effect calcium results: (not an all inclusive list)
The two most common issues following Weight loss Surgery or Duodenal Switch may be albumin level and Vitamin D level. Please see past blogs on Vitamin D. Magnesium may also play a role in a Duodenal Switch patient.
The most common calcium result drawn is the total calcium level. Laboratory results may not explicitly label it as such, however, it measures the calcium that is bound to protein. Ionized calcium is the free calcium that is representative of the true total calcium. Ionized Calcium can be measured by ordering specific lab. Alternatively, the Ionized calcium can be calculated by the following formula: Corrected calcium mg/dL = (0.8 * (Normal Albumin – Pt’s Albumin)) + Serum Ca ) or use the calculator at the bottom of this post.
The low Albumin level accounts for the low calcium level. This may be the reason for a patient with a low albumin/protein level, also having their calcium level reported as low. However, when adjusted for the protein deficiency the corrected calcium comes into normal range. Video of Trouseau’s sign of a patient with calcium deficiency.
The first step in a patient who has low calcium reported, is to make sure their protein and albumin levels are normal, along with Vitamin D.
Calcium levels are managed by two processes major regularly hormones and influencing hormones. Controlling or major regulatory hormones include PTH, calcitonin, and vitamin D. In the kidney, vitamin D and PTH stimulate the activity of the epithelial calcium channel and the calcium-binding protein (ie, calbindin) to increase calcium absorption. Influencing hormones include thyroid hormones, growth hormone, and adrenal and gonadal steroids.
