You’ve already cut out your morning latte and ruled out the sugary energy drinks in an effort to reduce your caffeine intake, but you still occasionally feel jittery or prone to headaches. If you’re making all of the right steps toward a caffeine-free diet but just can’t seem to catch a break, these surprising products may be to blame.

1. Dietary supplements. Frustratingly enough, one of your other attempts to lose weight and stay healthy may actually be the cause of your caffeine headaches. Dietary supplements, including multivitamins, often contain high doses of caffeine that aren’t always listed on the nutrition label. Some supplements even contain over 210 milligrams – that’s more than double the amount in one cup of coffee!
2. Chocolate. Chocolate, another popular vice among many adults, is known to contain just as much caffeine as coffee in some cases. If you need a chocolate fix, indulge in less intense milk chocolate instead of dark.
3. Tea. Switching your daily cup of Joe for a cup of tea still causes you to consume caffeine, contrary to what many may think. One cup of black tea has around 14 to 60 milligrams, while green tea contains 24 to 40 milligrams of caffeine.

Whether you practice a vegan diet or you simply want to reduce harmful fat and calories from your meals, cutting out butter is a healthy food choice. These simple butter substitutes will enable you to eat the foods that you love in a healthier manner, and they’ll taste just as delicious.

1. Olive oil. While olive oil is also high in calories, it has a number of other health benefits that butter doesn’t. For every cup of butter, you can easily substitute 1/4 cup of olive oil plus two tablespoons in order to maintain the same texture and consistency. Olive oil is also completely vegan, and it can be used to grease pans as well.
2. Commercial butter substitutes. Your local grocery store likely sells a wide variety of commercial butter substitutes and margarines that can be used in place of butter. These products usually have the same look, feel and taste, but they have much less fat and calories. Brands like Earth Balance and Smart Balance taste very similar to real butter, but unlike butter they’re completely vegan. Most chefs advise against browning commercial butter substitutes, however, because they burn very easily and don’t achieve the same effect.

No matter how diligently you count calories, it’s also very important to monitor your sugar intake when you’re attempting to shed a few pounds. Foods like cookies, ice cream, and sweet soft drinks are obviously off limits, but there are also a number of other sugary foods that might surprise you. Here are two common sources of sugar that might be flying under your radar.

1. Fat-free salad dressings. Seeking out fat-free foods in the grocery store may seem like a simple way to stay on track with your diet, but many of these products attempt to maintain the same bold flavor by loading on the sugar. Salad dressings in both creamy and oil-based forms are loaded with sugar from sources like honey and concentrated fruit juice. Be sure to check the nutrition information before you buy.
2. Multigrain cereals. Don’t just assume that all grains are automatically healthy. Multigrain cereals offer important fiber and whole grains that your body needs for energy, but unfortunately, many leading brands also include as many as six grams of sugar per cup. Many dietitians suggest opting for the plainest version of your favorite cereal and adding fresh fruit or a teaspoon of sugar instead.

There are a number of reasons to give up regular dairy milk, from food allergies to personal diet choices. If you’ve decided to take the plunge into dairy-free milk substitutes, these simple and tasty alternatives to cow’s milk will make the transition easy.

1. Soy milk. This is one of the most popular milk alternatives, and it’s been around for quite some time. Soy milk is made with filtered water, whole soy beans, and thickeners that give it the same thick, creamy consistency as regular milk, and they also make it easy to bake with. Most brands of soy milk even contain the same amount of protein, Vitamin D, and calcium as cow’s milk.
2. Almond milk. If you want to cut out milk in order to reduce your calorie intake, almond milk is a great alternative choice. This nutty mix of filtered water and ground almonds has only around 60 calories per cup, but it offers the same thickness and consistency as dairy milk.
3. Rice milk. Rice milk has a more neutral flavor than many other milk substitutes, and it’s a bit thinner. However, it contains the same amount of calcium and Vitamin D as cow’s milk, and it offers a light, sweet flavor that’s mild and pleasant.
