Hello! I hope you get well soon. I understand your point of view. As you can not exercise you will focus yourself in what you eat. You should consume more proteins such as fish, egg, chicken, cottage cheese, cheese milk , fruits and vegetables si you can fuel your muscles and less carbohydrates such as :rice, bread, spaghetti, cookies, and try not to eat fats saturated fats. Have you heard of intermitent fasting? It s a good way to lose weight. Intermittent fasting (IF) is an umbrella term for various diets that cycle between a period of fasting and non-fasting. Intermittent fasting can be used along with calorie restriction for weight loss. More generally, forms may choose to specify various ratios of fasting to non-fasting periods. The BBC2 Horizon documentary Eat, Fast and Live Longer[5] covered people who committed to fasting two non-consecutive days per week. Known as the 5:2 diet, people consumed 400–500 calories (women) or 500–600 calories (men) during the days of fasting. During feed days, the diet was regular. For some, intermittent fasting, or going a longer period of time — usually between 14 and 36 hours — with very few to no calories, can actually be a lot easier than you may think, and the benefits might be worth it. If you think about it, all of us “fast” every single day — we just call it sleeping. How It Works: Fast for 14 (women) to 16 (men) hours each day, and then “feed” for the remaining eight to 10 hours. During the fasting period, you consume no calories, though black coffee, calorie-free sweeteners, diet soda and sugar-free gum are permitted. (A splash of milk in your coffee won’t hurt, either.) Most practitioners will find it easiest to fast through the night and into the morning, breaking the fast roughly six hours after waking up. This schedule is adaptable to any person’s lifestyle, but maintaining a consistent feeding window time is important. Otherwise, hormones in the body can get thrown out of whack and make sticking to the program harder, Berkhan says. What and when you eat during the feeding window also depends on when you work out. On days you exercise, carbs are more important than fat. On rest days, fat intake should be higher. Protein consumption should be fairly high every day, though it will vary based on goals, gender, age, body fat and activity levels. Regardless of your specific program, whole, unprocessed foods should make up the majority of your calorie intake. However, when there isn’t time for a meal, a protein shake or meal replacement bar is acceptable (in moderation). Best regards.
