Warns Nutritionist and Dietician Avni Kaul

The menstrual cycle is a vital indicator of women’s reproductive health. Having regular periods is a vital sign though the menstrual cycle pattern is different for everyone. A normal cycle range should be in the range of 25 to 35 days for the optimum functioning of hormones. Periods that are too early or late can be impacted by several factors such as stress, anxiety, medication, and diet which have a crucial role in your menstrual health.

Understanding how your diet can impact your periods can help you make informed decisions with respect to what you eat and how it affects your body, says Avni Kaul. Avni Kaul, India’s top Dietician and Nutritionist shares the diet mistakes that may delay your periods.

Wrong combinations of food

It is essential to pay attention to the kind of foods you are combining and try to eat them in a manner that promotes healthy digestion and absorption of nutrients. Wrong combinations such as fruit after lunch and tea with breakfast interrupt important nutrient absorption that is needed for healthy and regular menstrual flow.

Consuming excessive processed food

Processed food is high in calories, unhealthy fats, and extra sugar, which could lead to weight gain and a rise in blood glucose levels that further affects the role of necessary hormones estrogen and progesterone involved in the menstrual cycle.

Skipping meals

Because of the hectic lifestyle or poor dietary choices, women tend to skip meals which slow down their metabolism and leads to overeating later on in the day. This in the long run could lead to deficiencies of vitamins such as B12, D3, and zinc which are necessary for healthy period flow.

Not having adequate fruits and vegetables

Fruits and vegetables are filled with nutrients and fiber, which make you feel fuller and decrease your risk of hormonal issues. Maintaining a healthy gut microbiome is vital for overall health, and might also help to alleviate symptoms associated with menstruation.

Having a balanced diet that includes a lot of fiber, fruits, and vegetables could help support a healthy gut microbiome. Probiotic-rich foods, like yogurt, amla pickle, sauerkraut, and kefir, might also be beneficial.

Not working on nutrient deficiencies

Only relying on supplements or medications to improve vitamin deficiencies is not recommended. To prevent nutrient deficiencies, it is important to eat a balanced diet that has a variety of nutrient-rich foods. If you suspect you have a nutrient deficiency, talk to your doctor or Dietician who can help you determine the cause and recommend proper treatment or dietary changes.

Avni approaches nutrition and wellbeing in a genuinely scientific and highly customized way. Her knowledge is impressive, but what truly stands out is the personalized element—it's clearly not a rigid, one-size-fits-all plan. I really appreciate that the process is designed to be flexible and adaptable to individual preferences and lifestyles. Beyond the methodology, the attention to detail and the support system she sets up are exceptional. She ensures the journey of nutritional improvement doesn't feel weary or lonely. Loved the gamification elements which made the process fun while encouraging a focus on sustainable, long-term habits. Would definitely recommend!!

When looking for someone to help you through your health journey, I think it is very important that the people who are guiding you do not approach it with any judgement. That is one of the best things I find about Avni & her team. They don't make food your enemy but rather teach you how to do it right, spending a lot of time in understanding your likes and dislikes and really personalising it to your need. You can be sure that you are being looked after individually. Alongside that, they also offer is a wealth of knowledge but also a delicate approach towards your journey. This is the main reason why I would recommend Avni to everyone.

In March 2025, I had a scare with a sudden spike in my sugar levels. That was my wake-up call—I knew it was time to take my health seriously. I wasn’t looking for a quick fix but a long-term, sustainable lifestyle change. That’s when a close friend introduced me to Avni and NutriActivania. I reached out to Avni, and we discussed my goals and what I hoped to achieve. She and her team immediately put together a plan tailored specifically for me. The best part was how flexible it was—no drastic cuts, no extreme measures. Instead, they focused on equipping me with the skills and habits I needed to make lasting lifestyle changes. They listened to what worked for me, especially in terms of food preferences, and built a plan around my life rather than expecting me to adjust to theirs. That level of customization is what made it easy for me to stay committed. Each week, they share a personalised food plan and always check in before finalizing it. Avni has been incredibly supportive—always available to answer questions and consistently encouraging me to stay on track. Over the last seven months, I have lost 9 kgs. My sugar levels are back to normal, my cholesterol has dropped, and most importantly, I feel healthier. I eat better, and I am far more mindful about what I consume. I truly believe they’ve given me the tools to make better choices and have been instrumental in helping me reshape my lifestyle. Thank you, Avni and team. Thank you for being part of my journey and for helping shape it in the best way possible.

During my first pregnancy, I was worried because I didn’t know how to give proper nutrition to my baby. Someone suggested Nutritionist Avni Kaul, so I joined her program and followed her diet plan throughout my pregnancy. She gave me a healthy meal plan that also allowed me to enjoy the foods I liked. My baby girl was born healthy and at a good weight. After pregnancy, I struggled with my weight, so I joined Avni Kaul’s post-pregnancy weight loss program. My weight went from 65 kg to 56 kg. I truly thank Nutri Activania and Nutritionist Avni Kaul for their support and guidance during my pregnancy and weight loss journey.

I visited Nutritionist Avni after struggling for months with low energy and irregular eating habits. She gave me a diet plan that was flexible, not restrictive, and I started feeling the difference in my energy levels within just a couple of weeks.
