18-10-8-4-1 method

According to Richa, it's her ‘signature’ plan where weight loss is simplified with the help of a few daily habits. The acronym makes it easier to remember the important steps and stick to them regularly.

Here are the habits which fall in Richa's 18-10-8-4-1 method :

  1. 18 hours of intermittent fasting. She explained, “I ate between 11 AM – 5/6 PM. Makes you lose weight and clears your mind, and better energy.”
  2. 10, 000 steps daily. The dietician urged everyone to hit their step count without any excuse, as it easily burns 500-700 calories.
  3. 8 hours of sleep. Resting is also vital, as Richa reminded that the body burns fat while at rest.
  4. 4 litres of water. Along with this for hydration, she suggested adding anti-inflammatory teas, as they help reduce bloating and improve skin clarity.
  5. 1 gram of protein per kg. Highlighting the utility, Richa added, “To preserve muscle and tone up."

Highlighting one of the rituals from her personal morning routine, she said she starts her day with a fat-burning MCT oil tonic, as it helps accelerate fat loss.

Intermittent fasting is commonly followed by people who want to lose weight. It involves alternating between eating and fasting windows and helps create a calorie deficit.

Richa shared the different types of intermittent fasting windows, and her take on each:

  1. 16: 8- 8-hour eating window. Perfect for those who want flexibility and eat during 12-8 or 1-9)
  2. 5: 2- Eat normally for 5 days, fast for 2
  3. 14: 10- Great for beginners, eat during 10-hour window, and fast for 14 hours.
  4. 18: 6: This type is her personal favourite. This one is intense but effective as it involves a 6-hour window and a fast for 18 hours.

As a lifestyle journalist, she crafts compelling, relatable narratives across diverse touchpoints of the human experience, including wellness, mental health, relationships, interior design, home decor, food, travel, and fashion that gently nudge readers toward living a little better. For her, stories exist in flesh and bones, carried by human vessels and shaped through everyday endeavours. It is the small stories we live and share that make us human. After all, humans and their lores are the most natural and raw repositories of stories, and uncovering them, for her, is akin to peeling an orange under a winter afternoon sun. Always up for a chat, she believes the best stories come from unfiltered yapping, where "too much information" is kind of the point. A graduate of Indraprastha College for Women, University of Delhi, and an alumna of the Indian Institute of Mass Communication (IIMC), Delhi, Adrija spends her idle hours cocooned with herbal tea and a gripping thriller, scribbling inner monologues she loosely calls poetic pieces, often with her succulents in attendance. On lazier days, she can be found binge-watching, for the nth time, one from her comfort-show holy trinity: The Office (US), Brooklyn Nine-Nine, or Modern Family. Dancing by herself to her peppy playlists, however, is an everyday ritual she swears by religiously.Read More
