Physical Sunscreens vs. Chemical Sunscreens – The Argument

Physical Sunscreens vs. Chemical Sunscreens – The Argument

When it comes to selecting a sunscreen, the options are seemingly endless. There are grocery store aisles devoted to this essential beauty product, but how many of those are made up of natural ingredients that deliver physical sun protection? Today I want to discuss the options you have in terms of physical UV protectants, and the benefits each has to offer!

What is the difference between chemical and physical sun protection?

Most of the sunscreens that line the aisles of your local grocery or drugstore are likely made with chemical sunscreen ingredients (either as a whole, or in combination with a physical UV protectant). These UVA/UVB fighting chemicals (of which there are many, many different options) work by absorbing the sun’s rays. While highly effective in the protection department, these chemical filters have been known to have higher irritation potential, and can even cause allergic reactions.

Physical sunscreens, on the other hand, work by physically deflecting or blocking the runs rays. It is like a physical layer of protection being placed onto your skin. The two ingredients that deliver this physical protection? Look for Titanium Dioxide (TiO2) and Zinc Oxide (ZnO) when browsing the sunscreen aisle. While both of these are known for being relatively skin friendly, experience shows that Zinc Oxide might be the better option for those who are prone to breakouts.

All About Titanium Dioxide.

One of the most beautiful benefits of Titanium Dioxide, aside from protecting your skin from harmful UVA/UVB rays, is how gentle it is on the skin. It is generally recognized as safe for use on sensitive or rosacea-prone skin, and is not a general culprit in the classic “sunscreen eye stinging” phenomena that occurs when you sweat or swim. One drawback? Titanium Dioxide can be heavy, hence: why it might not be the best option for acneic skin types.

All About Zinc Oxide.

Now, for the exciting part. While I love Titanium Dioxide for its ability to physically block UV rays while remaining friendly to the skin, I have always been in awe of the many things that Zinc Oxide can deliver. First, and foremost, it is one of the safest ingredients to use when it comes to protecting your skin from harmful UVA/UVB rays. But what else can this fantastic skin care ingredient deliver?

  • It Helps to Heal Your Skin: Zinc Oxide as an ingredient has a long history of aiding in wound treatment. It has natural antibacterial and anti-inflammatory properties that make it a wonderful asset to wound healing, and has been shown to help soothe diaper rash as well!
  • It is Great for Sensitive Skin: The same anti-inflammatory properties that make this ingredient so wonderful for wound healing also make it wonderful for sensitive skin. That includes eczema, psoriasis, and rosacea prone skin types!
  • It Can Benefit Acneic Skin: Multiple studies have actually linked the use of zinc (both topically and orally) to better skin. So if you have anceic skin, or are weary of sunscreen for fear of causing a breakout, simply reach for formulas that contain Zinc Oxide.

How to Use Physical Sunscreen vs. Chemical Sunscreen.

So you’ve decided to make the switch over to physical sunscreen. I am sure you are now wondering how you should use it in comparison to traditional chemical sunscreens. Luckily, these two should be used in exactly the same way. There is simply one distinct different: physical sunscreen starts providing protection immediately upon application, whereas chemical typically takes 15-30 to become effective.

Now, for reapplication.

No matter what type of sunscreen you choose, it is absolutely essential that you are diligent about reapplication. Believe me, as a skin care professional I have heard the gamut of excuses in the “why I cannot reapply” department – but the health and appearance of your skin really depends on this. Yes, sun damage is not only a leading cause of skin cancer, but also a leading cause of aging (wrinkles, sun spots, you name it!).

I recommend reapplication every two hours or more (depending on your activity level when out in the sun). If you are going to be spending your day indoors, save for those of you who work in windowless spaces, you still need to do your part to reapply 1-3 times throughout the day. You can find body formulas that are nourishing (like applying a lotion) and facial formulas that are quick, easy, and wont disturb your makeup (like a powered, brush-on formula).

The Conclusion.

More important than what type of sunscreen you choose is simply choosing to wear sunscreen on a daily basis. Whether you choose to go chemical, or decide to use physical, sun protection is essential to your appearance and your health. My closing note, as a skin care professional? If at first you don’t find a formula you love, try try again! Remember, there are so many different types of sunscreens out there – don’t be afraid to play around with the options!

Intermittent Fasting Weight Loss (The Ultimate Weight Loss Hack)

Intermittent Fasting Weight Loss (The Ultimate Weight Loss Hack)

Intermittent fasting weight loss is a type of diet that’s rapidly growing in popularity and becoming the way to lose weight. Scientists and nutrition experts like it, too. New books and articles on the topic are being published daily. Intermittent fasting is also popular with followers of the Paleo diet since our ancestors appear to have eaten this way for thousands of years.

I’ve been following this type of diet myself for 2 years. Doing so helped me lose and keep off 70 pounds without ever having to count calories, limit carbohydrates, or eat 6 to 7 meals a day.

This article teaches you all about intermittent fasting weight loss and details why it is one of the best weight loss diet hacks around. Once you finish, you will be able to implement into your diet and experience the benefits it offers almost immediately.

What Is Intermittent Fasting?

As you may have figured from its name, intermittent fasting weight loss is a diet plan where you set fasting periods during the day. This is usually between 16-20 consecutive hours, but it can be as little as 12 hours or as much as 24 hours (or even 36 hours).

While fasting you can eat and drink low calorie or calorie-free foods. Think coffee, tea, water, and vegetables.

The more time you spend fasting every day, the better your results. You can do these fasts as often as you like. Again, the more often you do so, the better[1].

Getting Started With Intermittent Fasting

Following this diet plan is super simple. All you have to do is choose a period of time during the day that you will fast. This should be between 16-20 hours.

The longer you fast each day, the better. Don’t worry about calorie restriction or measuring carbohydrates. Just focus on going about your day until it’s time to eat.

It’s best to choose a set period of time to conduct your fast. I like to fast from 8 PM to 4 PM the following afternoon. I’ll then have my first meal of the day and a snack or two a few hours later. Once 8 o’clock rolls around, it’s back to fasting.

My experience with intermittent fasting is that it’s best to start with a 16 hour fast (i.e. 8PM one evening to 12PM the next day) for the first 1-2 weeks. Once you are comfortable with this schedule, you can increase the amount of time you spend fasting. Do this by adding 30 minutes to each fast until you get to where you are fasting for 20 hours at a time.

You don’t have to fast every day in the beginning either. You may be more comfortable breaking in slowly with 2 or 3 days per week, or trying alternate day fasting. Add additional days of intermittent fasting as you become more comfortable with this style of eating.

Tips To Make Intermittent Fasting Easier

1. Drink Plenty of Water

Squeeze a little lemon or lime juice into your water to help get rid of any cravings you experience. You can also drink coffee, tea, or other calorie-free beverages. After a few weeks, you will find that intermittent fasting keeps you from craving sugar entirely.

2. Take in Caffeine in the Morning and Early Afternoon

The caffeine in coffee and tea may actually make intermittent fasting weight loss a little easier since it’s good for curbing your appetite. Be careful not to overindulge as this may lead to you feeling a little too wired. I also recommend these natural energy boosting tips to keep you going during the day.

3. Avoid Artificially Flavored Drinks

One type of calorie-free drink that should be avoided are diet sodas and other beverages that use artificial sweeteners like Splenda and Sweet & Low. Studies show that the can actually stimulate your appetite[2] like a drink that contains sugar and cause you to overeat.

4. Don’t Gorge at Your First Meal

The first meal after your fast should be the amount of food you typically eat. Binging will only make you feel awful and diminish the benefits you get from the fast.

To avoid this, try creating meal plans, at least for the first few weeks. This will help you get into the rhythm of eating regularly portioned meals during your eating window.

5. Minimize Processed Carbohydrates and Sugars

While intermittent fasting does make it possible to eat a little looser than normal, you should still eat as little bread, pasta, rice, etc. as possible.

Focus instead on eating protein from beef, fish, or pork, carbohydrates from vegetables, fruit, and sweet potatoes, and healthy fats from foods like almonds, avocados, fish, and olive oil.

How Intermittent Fasting Helps You Lose Weight

Eating this way has many benefits with regard to weight loss. The first is that when you’re fasting, your body will be forced to use its stored body fat for energy. Burning calories this way, instead of from the food you’re eating throughout the day, will help you experience significant weight loss, but specifically lose weight from any excess body fat you’re carrying.

This means that you won’t just be thinner, but you will also look better and be much healthier than if you lose weight the old-fashioned way[3].

Intermittent fasting can help optimize the release of the key fat-burning hormones in your body. This is especially true for the two most important hormones: human growth hormone (HGH) and insulin.

Human growth hormone plays a key role in turning on your body’s fat-burning furnace so that it gets the calories you need to work and play from stored body fat. Studies show that fasting can significantly increase the production of HGH[4].

The influence intermittent fasting weight loss has on insulin is just as impressive and possibly more important. Keeping your insulin levels low and steady is key to losing excess fat and keeping it off.

Diets that are rich in processed carbohydrates (bread, pasta, rice) and simple sugars (candy, cookies, and soda) have the opposite effect. They cause your insulin levels to rapidly spike and then crash every time you eat one of these foods. The net result of this phenomenon is that your body will store more of what you eat as excess body fat instead of burning it off as energy.

Chronically elevating your insulin levels like this can also lead to the development of type II diabetes, obesity, and other chronic health problems. Intermittent fasting easily solves this problem.

One study found that men who participated in intermittent fasting had “dramatically lower insulin levels and significantly improved insulin sensitivity”[5].

This happens because you’re not giving your body food, so it will not produce insulin, allowing insulin levels to balance out until you eat again. This helps your body stay in a calorie and fa-burning state. You’ll also find that it gives you more energy throughout the day.

Another great weight loss benefit of intermittent fasting is that hunger pangs and cravings that may normally plague you throughout the day will be reduced, if not altogether eliminated. This is probably due to its ability to balance your insulin and blood sugar levels and, in turn, help correct other hormonal imbalances.

Intermittent Fasting Weight Loss FAQs

Now that you know what intermittent fasting is and how to get started, it’s time to answer your other questions.

Below are answers to the questions frequently asked about intermittent fasting. These answers should help you and make getting started a lot easier.

How Much Weight Will I Lose?

The amount of weight you lose with fasting is determined by how often and long your fasts are, what you eat afterward, and other factors. Fasting for 16-20 hours a day can help you safely lose 2-3 pounds of fat every week.

While losing this much weight every week is great, it’s how it makes it happen that’s really cool. Losing weight with intermittent fasting means that you will never have to count calories or plan and prepare several meals a day.

Can I Work out While Fasting?

Yes, you can. In fact, doing the right type of workout while fasting will help you lose weight faster and even build muscle.

The best workouts to do while fasting for weight loss are 3-4 intense strength training workouts weekly. This means anything from standard strength training to kettlebell or body weight workouts.

Focus on doing 3-4 total body exercises per workout with as little rest as possible between sets. Doing this will help you burn more calories during and after your workout. You’ll also build muscle, which will help you look and feel better as the weight comes off.

Won’t I Lose Muscle When I Fast?

First of all, you aren’t fasting long enough for your body to start breaking down muscle for energy. You have, perhaps, hundreds of thousands of calories from your stored body fat to use before that will begin to happen. Studies actually show that even after fasting for 3 days, no muscle is lost.

Is Fasting Safe?

As long as you are healthy, not pregnant, and aren’t taking medications, fasting is safe. Like all diets, you should discuss it with your doctor before beginning an intermittent fasting style of dieting.

I also feel that it may not be smart to follow this type of diet when you’re especially stressed. Since this diet can be a little stress-inducing at first, doing so when your ability to be relatively stress-free and rested probably isn’t a good idea.

Are There Any Supplements I Can Take to Make Fasting Easier?

As with any other weight loss plan, it’s a good idea to take a few nutritional supplements to ensure that your daily requirements are met. This includes a once or twice daily multi-vitamin, fish oil, and vitamin D.

I’ve also found taking 10 grams of branch chain amino acids before and after my workouts really helps, too. They’re great for giving you more energy during your workout and decreasing post-workout muscle soreness.

Conclusion

Now you know what intermittent fasting is and how it can help you lose weight quickly, safely, and pretty much effortlessly.

If you want to give it a try, find a fasting schedule that fits with you lifestyle and give it a go.
