It is Possible to lose weight in 100 days if you strictly adhere to your caloric intake. Assume you workout for two hours every day for five days, including cardio (45 minutes), weight training (50 minutes with five variants of a single body area), and abs (25 minutes). The following would be your diet for the next 100 days to get the desired outcome:

After awakening, Drink warm carom seed (ajwain) water (please strain the seeds after boiling), followed by black coffee.
Have a light breakfast if you go to the gym in the morning, because I like to go at 12 noon (because my workplace opens around 3 p.m., Bingo!)

Breakfast should have fewer carbs and fat. Smoothies, fruit-infused oatmeal, cooked egg whites, vegetables, and sandwiches are all options. I am an eggitarian, thus I prefer to eat eggs before undertaking weightlifting workouts.

At lunchtime, you may have a balanced meal or avoid carbohydrates and fats by eating just protein-based foods, which will help you increase your calorie deficit. It will give you more energy to lift more weights the next day.

Water intake: Drink as much warm water as you can. This will help you control your cravings.

You may also drink green tea. I prefer green tea between 4 and 6 p.m., with protein bars (which have relatively little calories in comparison).

You should have a light meal around 8 p.m. I used to do it at 8 p.m., sometimes 9 p.m., due to my job schedule. You can have Paneer (100-gram lite saute) and soya chunks (boiled salty) for supper in a balanced amount, or you can have white eggs. Remember, you must limit your calorie consumption.

After dinner, take a 30-45-minute stroll to aid digestion and enhance your sleep cycle. I used to walk for an hour after supper at my workplace (of course, after finishing my responsibilities).

Repeat for three months to accomplish your target of 60 kg (if you were previously 82 kg). Reaching the desired objective takes both patience and consistency. You can cheat sometimes (during the day only), but you should avoid eating harmful items. Rest certain, you will begin a new lifestyle within 100 days. Good luck on your adventure!
