Does 800 calories diet take into account exercise?
When you follow the 800 calorie diet plan you need to make lifestyle changes and make a significant effort to change your eating choices.
Exercise may help you tolerate a low-calorie eating pattern because it gives you a chance to eat desired foods by calculating the calories you lost while you are doing your workout.
Find here the best exercises you can do to burn more calories:
1: High-intensity interval training (HIIT)
Studies show that (HIIT) affects vascular fats, which is the first culprit in insulin resistance and leads to type 2 diabetes.0 It also has a wonderful effect on mitochondria, the organelles in cells responsible for energy production.
2: Resistance training:
The more muscle you have, the more calories you can burn. That is why resistant exercise is the perfect workout for losing weight from your body fats and keeping your muscles strong.
Resistance training raises your body’s metabolism rate and helps you burn calories faster, even in rest time. It has also a lot of health benefits like lowering your blood pressure and controlling blood sugar, for best results you must do resistance workout sessions at least twice a week.
3: Incidental exercise:
Sedentary life raises mortality rate, that is the conclusion of a long-term study that took 15 years, starting from 1996 and until 2011. It’s not always easy to find time to exercise during the day, but you can try to fit incidental exercises around your daily activities.
To add some physical activities to your daily life you may try the following:
- When you go to work by bus, get off one bus stop early and walk.
- Use the stairs instead of elevators.
- During breaks, walk for 3 minutes.
- Move around the room when you talk on your cell phone.

- Go for a walk in the fresh air and listen to audiobooks instead of reading on a sofa.
