High Fat Diets: Just Another Fad


Are high fat diets really the best way to lose weight that the world has seemingly just discussed? The answer is a resounding NO! Trends come and go. There was a big anti-fat movement years ago. Now it has changed to the anti-carbohydrate movement. Both movements (or trends, rather) promised better health and weight loss. Before you jump on the anti-carbohydrate bandwagon, consider a few of the points below/

Carbohydrates are macro nutrients

There are 9 calories in 1 gram of fat, 4 calories in one gram of carbohydrates and 4 calories in one gram of protein. For those of you who would like to know, there are 7 calories in 1 gram of alcohol (and no, this is NOT a macro nutrient, wink wink).

Carbohydrates are good for you

Carbohydrates are good for you and should not be banned from our diets. This excludes sugar (the simplest carbohydrate), which should be brought to an absolute minimum except for fruits and vegetables or used to spike blood sugar before or after exercise. Our bodies break carbohydrates down for energy faster than fats and proteins. They are a great way to fuel up before exercise and refuel straight afterwards to put the body in recovery (muscle building) mode as soon as possible. Carbohydrates are also broken down into glycogen which is stored (along with other places like the liver) in the muscle, which attributes to their size. The more glycogen a muscle contains, the larger it is. Carbohydrates are not bad, but western diets almost always contain too much of them. The problem is therefore not carbohydrates, but the proportion in which they are consumed.

Fats are good for you

Fats are not bad for you either, except for plant oils used in extreme heat like deep frying. When plant oils are super-heated (like they are when they are used to fry things), they become very unhealthy for the human body. They contribute to unhealthy cholesterol levels, create unhealthy heart environments, increase risk of diabetes and can lead to obesity. Fats are more calorie-dense than carbohydrates but take longer to be broken down in the body for energy. Fats also keep you fuller for longer than carbohydrates. Fats are great in the morning because they take longer to break down so that you feel fuller and it therefore takes longer before the body starts to hunger for more calories. Because the body craves less for longer as a result of a fatty breakfast, it learns to break down its own fat for energy instead of relying on the quicker energy release from carbohydrates.

Protein is good for you

At the risk of being doctor obvious; protein is good for you, too. It cannot be stored in the body (except for in muscle mass, a storage we do NOT want to tuck into) and therefore should be accompanied by fats in the morning, when your body has not had any protein for hours of sleep. Your body needs protein to grow and build your body and muscles. Protein is also beneficial straight after your workout so that your body can recover and start the recovery/rebuilding process. High protein, low fat and low carbohydrate diets are okay for short periods of time to drop fat quickly, but can't be sustained for long periods of time because your body will start to break down muscle for energy.

Proportion

As you should be able to see from the three points above, the key to a healthy diet which supports your goals is proportion. There should be a healthy balance between all three macro nutrients. Focus on eating fats and protein in the morning, protein and carbohydrates around (before and after) exercise and a balance of all throughout the day, depending on your goals.

Price

This is my personal guess as to why trends are often swaying between high carbohydrate and high fat diets. Unfortunately, protein is more expensive than both carbohydrates and fats. Furthermore, the healthier foods are more expensive than the less healthy foods. This makes sense when you look at how well carbohydrates that trick the body into thinking that it is a protein are sold. Examples of these are beef and chicken flavored chips and noodles. People might be satisfying their cravings for more protein with cheaper versions which are actually carbohydrates or fats.

Calories

The best way to drop weight is to drop total calories consumed to levels below expenditure (the bodybuilding industry has been saying this for years). You can do this by increasing caloric expenditure, decreasing calories consumed (through diet) or a combination of both. It is important for optimum health to keep a good balance between carbohydrates, fats and proteins without completely avoiding any of them.

The real culprits to avoid are sugars, super-heated plant oils, additives and processed foods; not entire macro nutrients like carbohydrates or fats. Keep everything in balance and focus on having fewer calories than what is expended instead of excluding a food group that your body needs. STAY STRONG!
