Increase immunity at home
More portion - less calories
Recent studies by American scientists fromThe Northwestern Wellness Institute in Chicago showed that people who ate a large portion of vegetable salad as an appetizer before main dishes consumed a total of 12% less calories for lunch than those who immediately started eating hot food. And indeed, if you start a full meal with a huge portion of salad, a feeling of fullness comes quickly, it seems to you that you have already eaten quite a lot at lunch, so you automatically reduce the number and volume of servings of the following dishes. To be not only nutritious, but also useful, such a vegetable salad should include green lettuce (Romain or iceberg), fresh carrots, tomatoes, cucumbers, celery, mozzarella cheese, and fill it with lemon juice and a small amount of vegetable or olive oil.
Hot only for breakfast
It is easy to prove that hot breakfasts are muchhealthier and more nutritious than "dry." First of all, they have a lot less calories. For example, a pack (450 g) of dry oatmeal or muesli contains from 1400 to 2000 Kcal, while a portion of hot oatmeal (on water) will cost you only 300 Kcal (for the same 450 g). In addition, hot food is much more nutritious, it saturates for a long time and after it you hardly want to have a snack immediately upon arrival at work. But after a “dry” breakfast, it usually pulls in “hot” - you come to work and immediately drink a cup of tea or coffee, which are certainly accompanied by various high-calorie goodies.
We drink green
Prefer all carbonated drinks and fruit juices green tea. First, it is much more useful, and secondly - less calorie. 
In a standard Coca-Cola bank - 140 Kcal, whichequivalent to 9 teaspoons of sugar. In fruit juices, calories are not less, and more often even more than in soda (not to mention dyes and sweeteners, if you are fond of store juices in bags). In green tea, if it is not sweetened, 0 Kcal. Not too convincing? Then, perhaps, you will be convinced by the fact that green tea contains katokhins - substances that stimulate the body's ability to burn extra calories. In addition to all this, due to the presence in it of vitamins C and B, trace elements, antioxidants, organic acids, enzymes and alkaloids, green tea has antimicrobial, antiviral and regenerating effects and strengthens the immune system weakened during the winter period. 
Do not refuse sweet
If you want to eat something delicious, allsweets prefer chocolate. Black is better. Yes, chocolate is high-calorie (100 g - from 520 Kcal to 560 Kcal), but you can't eat much of it: one or two small pieces can be enough to quench the sweetness and improve your mood (and two pieces are about 20 g, t. is only 100-120 Kcal). Moreover, numerous studies have proven the ability of black chocolate to lower blood pressure and reduce the risk of cardiovascular diseases due to its magnesium, iron and potassium content. Chocolate also activates the production of serotonin - a hormone that improves our mood.
