Obesity is a condition that results from fat accumulation, which leads to many chronic autoimmune and inflammatory diseases.

Recent studies reported that humans affected by obesity and obese animal models have shown an impaired immune response leading to increased chances for various infections.[1]

One of our primary mottos is to get you into a journey of healthy lifestyle which helps you lose weight and stay away from obesity, and immunity building.

There are measures that will help you deal with bringing down obesity and build immune system, below are a few.


  • The immune system relies on white blood cells that produce antibodies to combat disease causing bacteria, viruses, and other invaders like COVID-19.
  • Research shows that excessive intake of fat impairs white blood cell function and that high-fat diets may alter the gut microbiota which helps in immunity.[2]
  • People belonging to obese category are to be consuming high fiber, adequate protein and complex carbohydrates along with other micronutrients rich diet.
  • For carbs, do not just rely on wheat & rice, but also have a variety of whole grains and millets.
  • Studies have shown that fruits and vegetables provide nutrients like beta-carotene, vitamin C, and vitamin E that can boost immune function. Because many vegetables, fruits, and other plant-based foods are rich in antioxidants, they help reduce oxidative stress. A plant-based diet with low fat helps to boost the immune system.
  • Add two servings of whole fruits (100 to 150 gm) per day and at least three cups of vegetables per day.
  • Vitamin D: Research shows vitamin D supplements may reduce the risk for viral infections, including respiratory tract infections, by reducing production of proinflammatory compounds in the body.[3]
  • Zinc is a mineral that can help boost white blood cells, which defend against invaders. Sources of zinc include nuts, pumpkin seeds, sesame seeds, beans, and lentils. 
  • ​Include the Immune Booster foods such as bright coloured whole fruits, fresh garlic, ginger, onion, tomato juice / tomato-based soups, non-starchy vegetables such as spinach, carrots, cauliflower and also you can have green tea/ black tea.
  • Make sure to consume protein foods such as sprouts/dal/legume preparation/curries/ egg whites in the diet. Limit non-veg for weekly twice and can opt for fish or skinless chicken breast etc.
  •  Prebiotics and probiotics play a major role in improving gut health, so include naturally fermented foods like Idli, Dosa, Dhokla, fermented kanji, germinated moong sprouts, pickled vegetables etc.
  • Include curds and buttermilk regularly in mid meals or along with major meals to improve gut health.
  • Include combinations of nuts and seeds which are sources of good fats. Seeds such as sunflower seeds, watermelon seeds, muskmelon seeds and nuts such as almonds, walnuts are health friendly. These seeds and nuts can be taken as a snack in the mid-morning or evenings.
  • Cut down on oil, it should not be more than 2 to 3 tsp every day if you are trying to lose weight. Use cold pressed oil instead of refined oils.
  • Eat your first meal within 30-60 minutes of getting up. And it should not be tea/coffee. Ideally, it should be a fruit/seeds/nuts/veg juice.

  • Avoid cold drinks and excessive intake of teas and coffees


  • Sleep: Inadequate sleep is linked to suppress immune function. It is a strong regulator of immunological processes, especially adaptive immunity. Also, Inadequate sleep results in obesity. Maintain a routine into which 7 to 8 hrs is given for sleep.
  • Quit Smoking: Smoking has an effect on both the innate and adaptive immunity. It suppresses the normal development and functions of the cells that are responsible for driving immunity in the body.
  • Alcohol: If you have a habit of drinking alcohol, drink alcohol in moderation. Alcohol is also known to impair immunity.
  • Stress: When you are stressed, the body releases excessive inflammatory promoting cytokines in the blood, and this will affect the normal function of immune cells.  Practice de-stressing activities like gardening, yoga, engaging favourite in hobbies like chess, Ludo, painting etc.
  • Exercise : Studies have proved that regular physical activity may enhance the immune system and provide protection against infection. Regular exercise is an important detoxing tool as well as beneficial for weight loss.  Exercise helps to relieve stress and increases the flow of oxygen to the brain. It stimulates our bodies to shed toxins and strengthen bones and muscles. Try to incorporate 30 minutes of physical exercise 5 times a week.
