The fitness industry is flooded with contradicting advice and quick fixes that rarely deliver lasting results. As a kinesiologist and certified trainer, Jeremy Ethier has spent years analyzing the science behind fat loss to identify what actually works. His approach isn't about extreme restrictions or complicated rules—it's about simple, evidence-based strategies that create sustainable results. These practical methods will help you not only lose fat but keep it off permanently by building habits you can maintain for life.
The Foundation: Calorie Deficitt
At its core, every effective fat loss diet serves one main purpose. Ethier explains in his post, "All fat loss diets, regardless of what you call it, have one simple goal—to get you into a calorie deficit, where you're eating fewer calories than you burn every day." Rather than focusing on eliminating entire food groups, Ethier's approach starts with an unexpected first step: eating more protein.
Protein: The Secret Weapon
Instead of restricting food, Ethier recommends beginning by increasing your protein intake. A compelling 2005 study showed participants who simply doubled their protein consumption got remarkable results. Ethier notes, "After bumping up their protein intake, the participants ended up eating 440 fewer calories every day without them even realizing it." Over 12 weeks, they lost nearly 10 pounds of fat without making any other dietary changes. Protein keeps you fuller longer and sends signals to your body to preserve muscle while burning fat, making it essential for sustainable weight loss.
Protein Portions Made Simple
Getting enough protein doesn't mean endless chicken breasts. Ethier admits, "Don't make the same mistake I did and start having chicken breast for breakfast, lunch, dinner, and dessert." He recommends aiming for at least 0.8 grams of protein per pound of body weight daily. This can come from various sources, including eggs, Greek yogurt, lean meats, tofu, and protein supplements. Incorporating a variety of protein sources you actually enjoy makes adherence much easier.
Don't Fear Carbs
Many popular diets demonize carbohydrates, but Ethier learned this approach has serious drawbacks. He shares, "By day three, I felt like complete crap. Super low energy and my gym performance sucked." Initial weight loss from low-carb diets is mostly water, not fat. Ethier explains, "When you cut out carbs, initially you're going to lose a ton of weight, but this is because carbs pull in water to your muscles." Research shows that as long as you maintain a calorie deficit and adequate protein intake, you'll lose fat regardless of carb consumption. Ethier suggests saving most of your carbs for around workout times when your body needs energy most.
Managing Fat Intake
While carbs and protein contain 4 calories per gram, fats pack more than double at 9 calories per gram, making them easy to overconsume. Ethier points out, "The real problems are often the hidden fats that pack on the calories without us even noticing." Simple swaps like using skim milk instead of cream, spray oil instead of liquid oil, and choosing leaner meat cuts can make a significant difference. However, Ethier emphasizes that complete restriction isn't necessary—moderation is key to creating a sustainable approach.
The Balanced Plate Method
Rather than following rigid meal plans that don't teach sustainable habits, Ethier recommends the balanced plate concept. He explains, "Instead of rigidly planning out your meals, most of your meals should look something like this." Fill a quarter of your plate with protein, half with vegetables and/or fruits, and the remaining quarter with either carbs and/or fats. This flexible approach works both at home and when dining out, eliminating the need for strict restriction while naturally controlling portions.
Supplements: What Actually Works
The supplement industry thrives on marketing hype rather than results. Ethier admits, "I've personally spent hundreds of dollars on fat burners back in the day. Yet the research is clear they're basically just glorified caffeine pills that spike your heart rate up a little bit to burn a small amount of extra calories." However, one supplement does stand out for fat loss: protein powder. A study from the British Journal of Nutrition showed subjects who added a 30-gram protein shake daily after completing a diet regained less fat and maintained smaller waist measurements. Quality whey isolate is Ethier's top recommendation for those struggling to consume enough protein.
Meal Timing and Frequency
Skipping meals often backfires, creating a cycle that leads to overeating later. Ethier shares from experience, "I'd end up feeling like crap by the end of the day and as soon as I finally ate something, my stomach would just be a bottomless pit that never got satisfied." While intermittent fasting worked well for Ethier previously, he now prefers eating 3-4 main meals daily spaced 3-4 hours apart, with 1-2 snacks when hunger hits. This approach helps maintain consistent energy levels and prevents extreme hunger that leads to poor food choices.
Mindful Eating Environment
Where and how you eat significantly impacts your weight loss success. Ethier references important research, "This study published in 2021 analyzed the food environments of over a thousand households. It found that one of the strongest predictors of being overweight was eating meals in front of the TV." Simple changes like slowing down, using chopsticks, employing smaller utensils, and sitting at a table without screens can reduce hunger and support fat loss. While occasional meals with entertainment are fine, making this a consistent habit may sabotage your progress.
Sustainable Progress Over Speed
Attempting to completely overhaul your diet overnight typically leads to failure. Ethier advises, "You'll make way more progress making just small changes at a time and aiming to lose even just half a pound of fat every single week consistently rather than losing a pound or two on some weeks and then gaining it all back again on other weeks." This gradual approach is more sustainable than rapid weight loss followed by rebound. He emphasizes that occasional setbacks are normal and shouldn't derail your entire journey—one poor meal or day won't undo all your progress.
Create A Diet You'll Actually Enjoy
The most effective diet is one you can stick with long-term. Ethier suggests, "If you find yourself cheating on your diet too often, then that's a sign that you need to make it more enjoyable." He personally avoids certain high-protein foods like canned tuna because he dislikes them, while finding ways to incorporate beloved Filipino dishes like chicken adobo and kare kare. The key is creating a personalized approach that respects both your nutritional needs and food preferences, ensuring you can maintain these habits for life.
