High Calorie Dessert Peanut Butter S’mores Bars

High calorie desserts are a great way to help reach your goals of gaining or maintaining weight.

Gaining weight or keeping on weight are serious issues that many people face. This can happen from a reduced appetite, being underweight, or if they are at risk of malnutrition. 

There are many reasons why someone may be struggling with gaining weight or a reduced appetite which can lead to not consuming enough calories throughout the day. This can become a concern because you may not be meeting your body’s needs. 

Why is Eating an Adequate Amount of Calories Important?

Not eating enough calories throughout the day can lead to many issues including malnutrition. Malnutrition occurs when someone is not getting enough nutrients for long periods of time. This can also lead to severe deficiencies in specific nutrients. 

There are less severe problems that can arise from not eating an adequate amount of calories each day. Food is energy! Not eating enough to fuel your day can lead to feeling sluggish or tired. 

If you exercise regularly, it is even more important to ensure you are consuming enough food to fuel your day and your body for your workout. Protein helps to build and repair muscle, and carbohydrates give you the energy you need to make it through those tough spin classes!

Your food intake also contributes to about 20% of your overall water intake. Considering the average American does not consume the recommended daily amount of water, not eating enough can also contribute to dehydration. 

Not only does your body rely on an adequate amount of calories to survive, so does your brain! Have a big test or important meeting coming up? Be sure to eat a proper meal to give your brain the energy boost it needs to do its best. 

Consuming a low amount of calories can also affect your gut health. Our digestion and gut health relies on intaking enough water and a variety of nutrients to keep it healthy and working properly.

Eating a low amount of calories can lead to constipation and feeling bloated, or other gut related issues. The food we eat directly relates to our gut health!

Butter: try swapping out for margarine or a plant based butter if you’re dairy free or vegan.

Peanut butter: swap with your favorite nut butter if you have an allergy, or do not like peanut butter. Some types of nut butter that would be delicious are; cashew butter, sunflower seed butter, or hazelnut butter.

Vanilla Extract: out of vanilla? Don’t worry! You can swap with another extract like almond, or even pure maple syrup!

Honey Graham Cereal: try Cinnamon Toast Crunch for more of a cinnamon flavor or Cheerios. For a chocolatey s’mores flavor, another great option would be Cocoa Puffs!
