With so many sources offering nutrition advice, it’s hard to know what’s true. Even factual information can become distorted by the time it reaches you. Like a game of telephone, the message often changes as it’s passed along. Here, we debunk 5 common diet myths to guide you toward the truth.
People with celiac disease are allergic to gluten, a protein found in wheat, and should avoid gluten in their diet. Otherwise, wheat and wheat protein are no more inherently fattening or harmful to metabolism than any other grain or component. The problem is all the flour products (bread/rolls, buns, crackers, muffins/cupcakes, pancakes/waffles, pasta, pretzels) made from wheat—those products are refined and lack the fiber and full nutrients that wheat kernels have. We can thrive perfectly well without the flour products (from any grain)!
The verdict – only those with an allergy need to avoid gluten. Whole grains of various kinds are better for everyone.
Too much of any macronutrient can provide excess calories and lead to obesity and metabolic disorder. Fat is high in calories (providing twice as many calories as carbohydrates or proteins per gram), however, it is an essential nutrient. You need some dietary fat for basic survival and body processes like hormone production and digestion. Several fat sources provide other nutrients such as fat-soluble vitamins (A, D, E, K) or essential fatty acids. Enough fat in a meal satisfies so you feel fuller longer, helping to stave off hunger. It also slows digestion a little to limit spikes in blood sugar.
The verdict – you shouldn’t cut out fat completely but could stand to reduce if your intake is high.
An external clock shouldn’t dictate eating if you are hungry. Absolutely, shift your calorie intake to the morning to fuel your daily activities. If you’re up until midnight, a healthy 9pm snack (around 150 calories) is fine. However, most late-night eating involves unhealthy options like ice cream and chips, rather than grilled fish and salad. Extra calories at any time can hinder weight loss efforts. Large volumes before reclining in bed can exacerbate heartburn.
The verdict – it’s not the clock but the choice of food in context of your day’s intake and activity pattern that matters.
Individual muscle fibers are made of contractile proteins, namely actin and myosin. Making new cells does take some additional protein, but only to the tune of 10-15 additional grams per day. In comparison, a tall glass of milk (1.5 Cups) provides 12 grams of protein and two eggs provide 14 grams. Research shows that there is no anabolic benefit to increasing protein beyond 35% calories when energy is adequate for growth. You really need an increase in overall fuel to support muscle growth with increased resistance training. As your total caloric consumption rises, so should your protein as a normal proportion of that intake.
The truth is that muscle growth requires carbohydrate and fat, too. Here’s why: Whether it’s for your skin, liver or muscle, each cell is made up of the elements carbon, nitrogen, oxygen, and hydrogen. Only amino acids from protein provide all four components, but carbohydrate and fat contribute three of them and act as fuel allowing the physical work that’s required for growth.
The verdict – it’s a very small raise in protein necessary to provide a critical building block for muscle growth.
Energy to supply our cells and muscles with fuel only comes from the macronutrient sources carbohydrate, fat, protein, (as well as the non-nutrient alcohol) which may get converted to ATP if not stored as reserves. ATP stands for Adenosine Tri Phosphate and is the compound that ultimately allows muscles to contract.
‘Energy drinks’ that are low-calorie and sugar-free don’t have significant macronutrients to turn into fuel. Instead, they have compounds like caffeine and taurine which trigger the nervous system, making one feel more alert or awake. Really, they are BUZZ drinks that hype you up, like when your body produces the neurotransmitter adrenaline when you are in danger.
The verdict – energy drinks do provide stimulation, but not necessarily fuel.
Adult onset diabetes is a condition with several factors contributing to its development, namely an excess of calories which leads to obesity and insulin resistance. A calorie surplus can come from too little physical activity as well as too much of any energy-contributing compound (carbohydrate, protein, fat, alcohol). Most sugary foods come with a lot of fat and therefore calories, and added sugars usually mean the food lacks fiber, protein and other nutrients.
Natural sugars in fruit and milk don’t increase the risk for Type 2 Diabetes. It’s a lot easier to drink a 16-ounce soft drink than to eat its sugar equivalent of 3 oranges! The American Diabetes Association notes that research points to sugary drinks being linked to Type 2 Diabetes risk and recommends people avoid drinking sugar-sweetened beverages.
The verdict – sugars, especially in liquid form, do contribute to extra calories and fat production which influence insulin resistance but don’t directly cause adult onset diabetes.

Eating the right foods before a workout can make a significant difference in your performance and recovery. The goal is to provide your body with the energy it needs to perform at its best while minimizing muscle damage. Here’s a guide on what to eat before a workout:
Carbohydrates are the body’s preferred source of energy, especially for high-intensity workouts. They help maintain blood glucose levels during exercise and replenish muscle glycogen stores. Here are some great carbohydrate-rich options:
Consuming protein before a workout can help improve muscle protein synthesis, increase muscle mass, and enhance recovery. Here are some protein-rich options:
While fats are not the primary fuel for high-intensity workouts, they are essential for longer, moderate-to-low intensity exercises. Healthy fat options include:
Staying hydrated is crucial for optimal performance. Dehydration can lead to decreased performance and increased risk of injury. Drink water throughout the day and consider having a glass of water 30 minutes before your workout.
The timing of your pre-workout meal can impact your performance. Ideally, you should eat a balanced meal containing carbs, protein, and fats 2-3 hours before exercising. If you’re short on time, a smaller snack 30-60 minutes before your workout can also be effective.
Avoid foods high in fat or fiber right before a workout, as they take longer to digest and may cause stomach discomfort during exercise. Also, steer clear of sugary snacks that can cause a rapid spike and subsequent crash in blood sugar levels. Eating the right foods before a workout can help you perform better and recover faster. Focus on a balanced intake of carbohydrates, protein, and fats, and stay hydrated. By fueling your body properly, you’ll be able to maximize your workout and achieve your fitness goals.

I’m 69 years old, I work out 3 times a week for 2 hours, 2 of those days are dedicated to upper/lower weight workout and the 3rd day strictly cardio on the treadmills and bike. I had a personal trainer for 6 months and I learned a lot of methods to workout. I’m careful with my intake and do not overindulge with high calorie or fatty foods, I’m frustrated when I get on the scale at the gym and at home, I gain pounds vs. seeing the numbers go down. It could be my metabolism (as one ages it drops drastically), just looking for answers, tips, suggestions. Thanks!
– Lydia C.
I understand your frustration, Lydia. Total pounds are easy to measure but won’t reflect body composition improvements. Ideally, you’d have tracked body fat percentage over the last 6 months. A tilt toward lower fat and more lean body mass indicates your metabolism should keep up. As body fat is reduced and muscle is gained the scale may not change (or go up). There is water stored with every pound of muscle, due to increased glycogen capacity.
Another approach is to monitor waist, hip, and thigh circumferences by breaking out the tape measure. Reflect on how your clothes fit. If you’ve got any more wiggle room than 6 months ago – success! Also note progress in fitness level… strength, endurance, and intensity level. All these observations are better indicators of improvement than total weight.
It makes a difference whether your weight workouts are focused on heavy weight with lower repetitions or more repetitions with less weight. The latter helps develop strength and muscles’ functional output while the former is intended to build up muscle (thus may increase weight). Once you tolerate a level of cardio (time, intensity, duration, or frequency) you’ve adapted to it and need further increases to promote greater fat burning. In the same regard, if your diet is good, but no better than before, then physique change is less likely.
In summary: focus on body composition, not scale weight, and look to where you can refine your diet and exercise regimen. Keep up that dedication!

My name is Martin and I have Type 2 Diabetes. My A1C is very high and I struggle with a good diet plan or what to eat. Do you have any advice for me? Thank you
– Martin
So glad you realize the importance of controlling your diabetes, Martin. The best advice will be directly from a Registered Dietitian that you can sit down with and go over your particular diet and daily blood sugar levels, not only your Hemoglobin A1C. Preferably that person should also be a Certified Diabetes Educator® (carries the CDE® credential) who is a health professional who possesses comprehensive knowledge of and experience in diabetes prevention, prediabetes, and diabetes management.
Top recommendations for Type 2 Diabetes from such experts address weight control and balanced meals, including the following advice*:

I’m wanting to start intermittent fasting for the numerous benefits it has… yes, including a little fat loss as well! The only issue is that I’m also trying to add muscle at the same time. Subscribing to the 1-2 grams of protein per body pound theory, is that enough time in the IF window to ingest that much protein? (I weigh 230 now, that’s a lot in a short window of time! ? What are the recommendations in order to achieve this with IF and low-carb/high protein? Is it even possible? Thanks!
– Chris T.
First, I’d modify your protein goal to the lower end of the range you proposed: 1 gram per pound goal body weight. That’s still over the 1.7 gm protein/kg recommended by the American College of Sports Medicine to increase muscle mass. Since there is no physical storage of amino acids in the body, consuming large quantities of protein at once doesn’t mean you’ll use all of what you eat.
For intermittent fasting, I’d advise breaking down your total so that you’re consuming 30-40 grams of protein* every 2-3 hours for the span of time you do eat. Remember to support your workouts with protein before, during and after to provide your muscles with amino acids when it needs them most and to promote muscle protein synthesis.
* Amount of protein generally supported in the literature as that which can be utilized at one sitting.
