A beginner's guide to: Calorie density and food choices
Learn how to feel full and satisfied while maintaining a calorie deficit by making smart food substitutions based on calorie density.
- Calorie density matters - choose foods that fill you up with fewer calories
- Prioritize protein (1g per lb body weight) for satiety and thermic effect
- Swap high-calorie foods for lower-calorie alternatives (e.g., rice → cauliflower rice)
- Load up on high-volume, low-calorie fruits and vegetables
- Watch out for hidden calories in sauces and dressings (can add 150+ calories)
- Artificial sweeteners are safe and effective for curbing cravings
While one part of the weight loss equation is being in a caloric deficit, this doesn't mean that you have to starve yourself! It's not just how much to eat, but what are you actually eating?
Ask yourself this:

What would make you feel more physically full? A handful of nuts, or 2 bowls of strawberries?
Making these informed switches will make your weight loss journey significantly easier and won't leave you feeling starved!
For a 500 calorie daily deficit - it's as easy as making the following substitutions:
Swap rice for cauliflower rice, swap soda for diet soda, remove the dressing from your salad and replace the protein with a lean source of protein!
Here are some of my personal favourite sources of macronutrients
(Note: the values provided are estimates only)

- Ham / processed meats: 1.4 calories / gram
- Lean turkey: 1.2 calories / gram

Carbs (1g of carbs = 4 calories)
Less calorically dense:
- Pumpkin: 0.4 calories / gram
- Potato: 0.77 calories / gram
- Sweet Potato: 0.86 calories / gram
More calorically dense:
- Oats: 3.8 calories / gram
- Rice (cooked): 1.3 calories / gram
- Pasta: 1.6 calories / gram
Fats (1g of fat = 9 calories)
Less calorically dense:
- Salmon, Eggs, Red Meat provide a healthy source of fats (I typically get my fats from my fattier sources of proteins)
- PB2 (Powdered Peanut Butter): 3.8 calories / gram
More calorically dense:
- Avocados: 1.6 calories / gram
- Butter / Oil: 9 calories / gram
- Nut Butters: 6 calories / gram
Some other helpful tips / tricks
Prioritise Protein
Why it helps:
- Keeps you feeling full longer
- Has a higher thermic effect (your body burns more calories digesting it)
- Aim for 1g of protein per lb of body weight
- Still need carbs for energy and fats for hormone regulation
Fruits and Vegetables
High volume, low calories - perfect for feeling satisfied. Some of my favorites:
- Mushrooms
- Broccoli
- Cauliflower
Artificial Sweeteners
Safe and effective:
- No long-term negative side effects shown in studies
- Great for curbing sweet cravings
- Can save 150+ calories (e.g., Coke Zero instead of regular Coke)
- Available in: No-sugar Jello, Ice-cream, Maple Syrup, and more
Sauces / Dressing
Watch out: Can add 150+ calories to a salad without you noticing.
Better alternatives:
- Hot Sauce
- Nandos sauce
- Fat-Free Mayo
- Soy sauce
- Or simply ask for sauce on the side!
Pro tip: Low calorie recipes and cookbooks like this one can help you get creative with your substitutes!
Remember: To help yourself feel more full on a calorie deficit - prioritise foods which are less calorically dense!
