Protein is very crucial as it forms a part of every cell, tissue and organ in the body. Post weight loss surgery meeting your ideal protein requirement is extremely important. All bariatric surgeries lead to restricted intake which in turn leads to a drastic decrease in the total number of calories consumed daily. In case of mal-absorptive bariatric surgeries, along with restriction the absorption of proteins is also affected. Indians are primarily vegetarian. Even those who consume non-vegetarian foods, do so in small quantities. Hence post bariatric surgery, it is extremely important to lay stress on this aspect of nutrition.
The major role of protein is to rebuild and maintain muscle mass. In addition, protein has many other roles to play, like it enhamces the wound healing post surgery, it enables the immune system to work efficiently, helps to maintain healthier hair, skin and nails and provides satiety which prevents hunger pangs in the subsequent meals.
Low caloric intake post-surgery, compels the body to use fat stores as well as muscle mass as a source of energy which results in the loss of lean muscle mass.
A daily protein intake of 1.5g/ Kg/ Ideal Body Weight has shown to prevent muscle loss (Moize. V. et. al., 2003). After bariatric surgery, for vegetarians, it is difficult to meet such high protein requirements through diet alone. Adding protein supplements to a high protein vegetarian diet thus becomes necessary to reach the ideal protein intake.
To keep up with the protein requirement of the body, the golden rule post weight loss surgery is to include a protein rich food in every meal. Let us have a look at few vegetarian foods rich in protein,
- Low fat milk/ Low fat curds/ Unflavoured Yoghurt
- Home-made Cottage cheese/ Tofu
- Soy granules/ Soy chunks
- Dals and Pulses
- Combining dal/ pulse/ sprout with cereals (Rice/ Wheat/ Jowar/ Bajra/ Ragi/ Maize) in 1:1 proportion increases the quality of proteins.
You can incorporate one or more of these protein supplements listed below as prescribed by your Bariatric Nutritionist keeping in mind your requirements,
- Protein powders – Whey isolate/ Whey Concentrate/ Other high protein blends (E.g. Soy + milk proteins/ Peanut + milk proteins, etc)
- Protein bars
- Protein chips
- Threptin biscuits
Protein supplements are very important for atleast the first 10-12 months post the surgery. Later on, your intake increases fairly to meet the protein requirements through diet. Even after 1 year if protein rich foods are not consciously included in the diet, then continuing protein supplementation through external sources becomes unavoidable.
The compliance with protein supplements has always been poor due to its strong aftertaste, and food aversion post-surgery makes it even worse. However, with technological advancements the protein powders are getting better in terms of their taste and texture. There is a wide variety of flavours available in the market. In case you have tried many and still not being able to get your taste buds accustomed to it then you can try few tips to improve palatability,
- Opt for vanilla flavour, as you can add some coffee powder/ fresh fruit to it for taste
- Consume it chilled
- Make it into a Smoothie by adding some yoghurt and fruit
- You can add the protein powder to oat flour and make mini protein pancakes
What happens in case of protein insufficiency
Proteins play a very important role in the transport of various vitamins and minerals. Insufficient proteins in the body can affect the availability of vital nutrients such as iron, calcium, copper, and vitamins A & D.
Its insufficiency results in various symptoms like,
- muscle wasting,
- thinning or brittle hair,
- pale skin,
- flaky or dry skin,
- headache, etc.
Few suggestions to ensure sufficient protein intake are as follows,
- Don’t miss your follow-ups
Being regular with your follow-ups will help you to identify if you are deficient in protein
- Maintain a diary
This option works great as you are aware how close or far you are from meeting your requirements. You just need to take out 10-15 minutes to write it down. End of the day is a good time to reflect and note down. Probably its even more effective than Almonds for improving your memory.
- Maintain a checklist
You can consult your Bariatric Nutritionist to prepare a checklist of protein rich foods to be consumed daily as per your requirements. Put up that checklist in the kitchen so that you don’t forget your PROTEINS.
So please ensure that after bariatric surgery you are taking enough protein. If you are unable to do that, please get in touch with your bariatric nutritionist for her guidance. Prevention is always better than cure!
