In a recent Instagram video posted on June 30, Rujuta Diwekar urged people to move away from crash diets, viral health trends, and unrealistic expectations.In the video titled ‘If you are trying to lose weight, keep in mind these three things’, she explained that long-term health should always be given importance over quick results. Her advice focused on sustainable weight loss, traditional eating habits, and consistency rather than shortcuts.ALSO READ: ‘Microsoft powered genocide for 994 days’: Employee quits in dramatic resignation emailRule 1: Don't rush weight lossAccording to Rujuta, one of the biggest mistakes people make is expecting rapid results."Number one: do not be in a hurry or haste. Lose weight comfortably. Whether you want to lose 2 kg or 20 kg, the approach should be the same: it should be sensible and sustainable. Sustainable means losing 5 to 10% of your body weight in a year."She stressed that healthy weight loss is a gradual process and should not come at the cost of overall well-being.ALSO READ: Family leaves New York, buys $13,000 home in Italy and later purchases a second property"If you need to lose more, it will take more years, but weight should only be lost gradually. Only then does the risk of diabetes, high blood pressure, thyroid issues, osteoporosis, and certain cancers decrease. Only then do your skin, hair, and mood remain good, and the frequency of infectious diseases also decreases. Uric acid issues also diminish."In the caption accompanying the video, she also wrote, “Losing weight while retaining strength, immunity, and bone density is key.”Why slow weight loss mattersMany people focus only on the number displayed on the weighing scale. However, experts often point out that sustainable fat loss is linked to better long-term health outcomes and is easier to maintain than extreme dieting. Rujuta Diwekar's message was clear: protect your health first and let weight loss happen gradually.Rule 2: Eat traditional foods instead of following diet trendsThe nutritionist also challenged the growing obsession with counting every gram of protein, fibre, or other nutrients."The second rule is that the diet you follow should be based on food-based dietary guidelines. Food-based dietary guidelines are a gold standard in nutrition science," she explained, adding, "This means your diet should include the traditional food that you have always been eating. Whether you eat dal-rice, idli-dosa, chicken and rice, or fish, your diet should be built accordingly. It shouldn't be that everyone is eating the same thing."She believes that traditional regional diets offer a more realistic and sustainable way of eating than one-size-fits-all plans and also warned against turning nutrition into a numbers game."You shouldn't have a diet where you are told to consume 30 grams of protein, 30 grams of fibre, and a certain amount of omega-3 in a meal. When you eat a diet focused on specific 'nutrients,' the profits of the weight loss and food industry increase, while your weight and frustration both begin to rise."Highlighting India's rich food diversity, she added: "Remember that the diversity in our food is the strength of our culture. We do not need to eat like one another; we need to eat like ourselves on a day-to-day basis, and that is what leads to sustainable weight loss."Traditional diets can be easier to followInstead of eliminating familiar foods, Rujuta encourages people to build their meals around what they have traditionally eaten at home. This approach can be easier to maintain over time and may reduce the frustration that often comes with restrictive diet plans.Rule 3: Avoid ‘magic ingredients’ and quick-fix productsRujuta's third rule addressed the flood of wellness hacks and viral diet trends circulating on social media."The third thing you must keep in mind is that there should be no 'magic ingredient' in your diet. This means there should be no advice suggesting you skip dinner to drink a specific shake, or wake up and take a fenugreek (methi) shot, gond katira, or a turmeric and ginger shot," she observed, adding, "There should be nothing out of the ordinary that you were not already doing."She said lasting results come from consistency rather than special products. "There should be no magic products; the magic is in the process. Which process? The one of regularity and consistency. So, forget the magic of products; find the magic in the process. And if what people are telling you to eat is an Instagram trend that everyone else is following, then don't do it. Keep these three things in mind and lose your weight with happiness, peace, and ease."Consistency beats trendsFrom detox drinks to expensive supplements, new weight-loss trends appear almost every week online. Rujuta's advice is to stay grounded and avoid chasing every new health fad.Her message is simple: regular meals, familiar foods, and consistent habits often work better than dramatic dietary changes.Disclaimer: This article is based on a user-generated post on Instagram.
