What’s the Best Diet? Science Says It’s the One You Can Stick To
With so much conflicting information available at our fingertips, many people struggle to know what to do when it comes to their diet and healthy eating. We often hear questions like:
- “What’s the most effective diet for weight loss?”
- “Should I eat low-carb or low-fat?”
- “Which foods will help me lose weight?”
Among our members, one of the most common questions remains: “What is the best diet?”
The question "what’s the best diet?" plagues many seeking weight management and struggling to lose weight. With obesity rates soaring – affecting approximately one-third of children and two-thirds of adults in England – and projections suggesting only 1 in 10 adults will be a healthy weight by 2050, finding a sustainable eating approach is crucial. The truth is, there’s no magic bullet. Numerous studies compare low-carb vs. high-carb, low-fat vs. high-fat, ketogenic vs. carbohydrate cycling, and various other approaches, but the results often highlight a surprising factor: adherence.
A meta-analysis of 11 well-known diets published in the Journal of the American Medical Association supports this. This study examined weight loss at 6 and 12 months across various diets (including Atkins and Ornish, which showed high initial success), revealing several key points:
-
Any diet is better than no diet: Participants on any structured plan lost more weight than those with no dietary changes.
-
Short-term vs. Long-term effects: While low-carb diets showed greater weight loss initially (8.73 kg at 6 months compared to 7.99 kg for low-fat), this difference diminished over time. After 12 months, low-carb and low-fat diets yielded nearly identical results (approximately 7.25 kg weight loss).
-
Behavioral support and exercise matter: Behavioral support provided additional weight loss in the short term (3.23 kg at 6 months), but the effect of exercise became more prominent over the longer term (2.13 kg at 12 months), regardless of the specific diet followed.
-
Adherence is key: The study concluded that the most effective diet is the one an individual can consistently maintain.
So, What Is the Best Diet?
The answer is simple: the best diet is the one you can adhere to consistently. Research indicates that adherence is a critical factor in weight loss success, regardless of the specific diet followed. Studies comparing various diets have found that while there may be differences in short-term weight loss, these differences often diminish over time. Adherence remains the primary factor associated with long-term weight loss.
Personal preferences play a significant role in diet adherence. If you enjoy carbohydrates and have an active lifestyle, a higher carbohydrate diet might be more suitable for you. Conversely, if you prefer fats and find it easier to limit carbs, a low-carb diet could be more appropriate. The key is to choose a diet that aligns with your preferences and lifestyle, making it easier to stick with in the long term.
Tips for Setting Up Your Ideal Dietary Plan:
At Hall Training we help each of our members build and create a personalised eating plan around them! There's no secret in what we do, so let me share our framework with you:
-
Prioritise Personal Preferences: Choose a plan that’s easy and convenient, whether it’s low-carb, calorie counting, or avoiding liquid calories.
-
Tailor It to Your Goals and Lifestyle: Active individuals might benefit from higher carbohydrate intake, while those aiming for weight loss might focus on calorie reduction. A flexible approach may suit those with busy social lives.
-
Address Medical Needs: Consider any allergies, intolerances, or conditions like hyperinsulinemia that might influence dietary choices.
-
Balance and Moderation: Whether you're eating for health, strength, performance or weight loss, moderation and balance is key.
-
Prioritise Protein Intake: Higher protein intake is consistently linked to success in weight loss and muscle gain programmes - we see this all the time with our own members.
The Role of Calorie Balance
Regardless of the diet chosen, maintaining a calorie deficit is essential for weight loss. Studies have shown overconsumption and underreporting of calories are common factors in diet failure. While adherence is crucial, research has proved accurately tracking calorie intake is vital for effective weight management.
In Summary
Ultimately, the best diet is the one you can stick to over the long term. There’s no single perfect diet for everyone—success depends on sustainability, personal preferences, and lifestyle, enabling you to adhere to it consistently over time. Choosing an approach you enjoy and can maintain will always yield better results than jumping from one fab diet to another.
