You do not have to go cold turkey and stop consuming all salt, sugar, and fat. Try substitution. Next time you are really hungry for a snack, substitute the potatoes chips with a piece of fruit or a vegetable that has not been fried.
Take this in baby steps. Let your body adjust to food that is healthy and find out the great taste of fresh food. Food that hasn't been manufactured to stay on the shelf for extended periods. Think about it, if the food you eat does not spoil, then it is not natural or healthy.
When you cut back on salt, you will improve your blood pressure, you will lose weight from having less water retention.
When you lose weight and your blood pressure is lower, you feel better, sleep better, and will be on your way to a healthier life.
When you cut back on sugar, you will have the same thing happen: lose weight, lower blood pressure, sleep better and feel healthier.
When fat is cut back, the fat that you have will start to melt away. You lose weight, lower blood pressure, sleep better and feel healthier.
This may all sound simple and it may also sound too hard to do, especially after the holidays and all the temptations of food with an excess of these ingredients.
This I will promise you, if you take small steps and stay on track with eating healthy, you will feel better. Maybe not at first, because your body has to get rid of some of the toxins that have been ingested, but you will start to feel better.
The other thing I can promise is that if you continue to eat unhealthy, it will catch up to you and you will have to deal with the illnesses that plague society now.
Live life healthy, the price is too high not to.
