Starting my one meal a day diet for a month

1st get a full body checkup up done. You will miss nutrition if u follow above routine. Include dal and more protein source + roughage

OMAD is notoriously difficult to sustain. It also isn't advisable because you will run a substantial nutrient deficit very quickly. This results in long term damage including muscle atrophy amongst other things. Your weight will also yo-yo depending on when you stop. Please consult a nutritionist and engage a fitness trainer. You need to do both - increase your BMR and optimise food intake.

Not sustainable, you will gain back all which you have lost. Join Fittr take help of nutritionist.

If you’re looking for a sustainable option, definitely not the way to go. As someone who didn’t have meals on time for a long period and struggling with gastritis now, take it from me. Please please eat! Develop a healthy relationship with food. I really can’t stress this enough. What worked for me is calorie deficit (high protein, medium carb and fat), clocking ~10k steps a day, lifting thrice a week and getting enough sleep. I lost 4kg in two months. In your case, if you can’t work out, even mild moving everyday will work. Use tdeecalculator to find your calorie needs and find the calories you need under cutting. Use Myfitnesspal and track your calories diligently. I’ve even gone back to my maintenance calories now and increased workout as I found it hard to be in deficit for more than two months. Don’t try to find an easy way to lose weight and let other aspects of your health suffer.

Lost 8kgs in 4 weeks. Did intermittent fasting for about 4 days a week (skipped breakfast), salads for lunch, and a decent dinner (continued to pig out for two meals during weekends) zero desserts. Morning cardio heavy workout for about 45 mins and evening brisk walk for about 3-4 kms. Can’t survive on one meal a day, too much of a foodie, kudos if you can sustain but I’d say once you achieve your ideal weight, gradually go to 2 meals a day
