When it is very hot (heat wave) the body naturally increases sweating, thus maintaining its temperature within normal limits.
In the summer the body does not need as many calories as in the winter and this is because…. it gets hotter. The calorie is a unit of measurement of heat, so with more calories we have more heat in the body.
Also we do not need to consume a large amount of complex carbohydrates. Simple natural sugars will give us energy and will not heat us up as much as if we were constantly sweating.
Proteins can be increased so that we do not feel hungry, because the body takes longer to digest them and also we will not retain so much fluid in our body (carbohydrates retain fluid in the body) and to keep our muscle mass stable. Muscle mass will remain stable with the right amount of protein along with a few carbohydrates. During a prolonged period of heat, you may notice muscle bloating if you do not eat any carbohydrates at meals, because the muscles will become slightly dehydrated (muscles have a small carbohydrate store inside them).
Water should never be reduced because we may become dehydrated (symptoms include fatigue, lack of energy, drowsiness, foul-smelling urine with a bright yellow color, inability to urinate, loss of sweating, fainting).
Coffee causes dehydration, as do alcoholic beverages.
It is wise to consume up to 5 meals (breakfast, brunch, lunch, afternoon snack, dinner) with breakfast and afternoon snack being fruits or nuts.
Our breakfast can be light and… stable, such as toast, bread and egg, muesli, toast with low-fat cheese, some fruit.
Our main meals (lunch, dinner) must have vegetables and definitely a satisfactory amount of protein. They can contain eggs, low-fat cheese, chicken, turkey, beef, fish. They should not be fried because fat makes the meal calorically heavy. Grilled or boiled with a little olive oil is the best choice.
The evening meal, if it does not contain vegetables with protein, can contain low-fat yogurt with nuts, fruit and a little honey.
