Diet fit

Which diet actually fits you?

Fat loss at equal calories is nearly identical across diets. What differs is adherence, logistics, early water weight, and medical fit — so we compare those, not miracle claims.

The honesty rule

We will never claim one diet burns more fat than another at the same calorie deficit. The quiz ranks diets by how likely you are to still be on them in 90 days.

Keto
🔥 Metabolic Fuel Switch · No Cravings
Train your body to run on fat 24/7 instead of sugar. Rich, satisfying meals and no between-meal hunger.
Very low carb, high fat — predictable ketosis when you stay under the net-carb ceiling.
Zero between-meal hunger
Healthy fats and protein keep satiety high for hours on end.
Mental clarity & zero blood-sugar crashes
No post-lunch insulin spikes — smooth, linear energy from morning to night.
Fast, visible 14-day kickstart
Rapid drop in water retention and bloating starting in week one.
🥩 Butter-basted steak with roasted asparagus🥑 Crispy skin salmon with avocado & lemon🍳 Creamy aged-cheddar & herb omelet
Honest con: Socially hard; week-1 scale loss is mostly water; electrolytes matter. Keto does not burn more fat than another diet at the same calorie deficit — adherence and protein do the real work.
What to eat
Prioritise fatty fish, eggs, poultry, beef, leafy greens, avocado, olive oil, butter, cheese, and nuts in measured portions. Build plates around protein + fat + non-starchy vegetables. Use berries sparingly.
Watch / avoid
Sugar, flour, most fruit juices, bread, pasta, rice, potatoes, and sweetened drinks. Watch sauces, coatings, and “low-carb” packaged snacks — labels hide carbs fast.

Low-carb
⚡ Steady Energy · Relaxed Rules
Fewer carbs without strict rules. Room for berries, yogurt and dinner out.
A looser net-carb band than keto — more flexibility while staying low-carb.
Steady energy, flexible pace
Cut refined carbs and sugar without strict ketosis tracking.
Effortless at restaurants
Any grilled protein with vegetables fits right into your plan.
Room for berries & dairy
Keep low-glycemic fruits and cultured dairy in your daily rotation.
🍗 Herb-roasted chicken with parmesan broccoli🥗 Loaded Greek salad with feta and olives🍓 Greek yogurt bowl with walnuts & berries
Honest con: Neither the simplicity of a balanced deficit nor keto’s appetite drop. Mid-band carbs can feel like “neither camp,” which makes restaurant choices fuzzier without logging.
What to eat
Lean and fatty proteins, non-starchy vegetables, eggs, Greek yogurt, berries, and modest portions of whole-food carbs (small rice/potato servings) when they fit the band. Keep most days in a looser net-carb band than keto — roughly 40–60 g unless you override.
Watch / avoid
Sugary drinks, desserts, large pasta/rice piles, and mindless grazing on chips or sweet snacks. You do not need ketosis messaging — skip “cheat day” framing that undoes the carb band.

Balanced deficit
⚖️ Eat Everything · Smaller Portions
Lose weight eating normal family food. No food is off-limits, just smart portions.
A straightforward calorie deficit with a balanced macro split — no food group is off-limits.
No banned food groups
Keep bread, pasta, and fruit in calibrated, satisfying portions.
Cook once for the whole table
Everyday meals your partner and family already love.
Built for 90-day consistency
No extreme rules — just predictable, sustainable calorie balance.
🍝 Whole-wheat pasta with lean turkey ragu🍚 Teriyaki salmon rice bowl with edamame🥪 Toasted chicken, avocado & greens sandwich
Honest con: Slowest visible early progress; requires accurate logging to work. Equal-calorie fat loss matches other diets — do not expect a dramatic week-1 water drop.
What to eat
Any whole foods that fit your calorie target — oats, eggs, fruit, grain bowls, sandwiches, pasta with lean protein, potatoes, yogurt, and vegetables. Hit protein near the floor; macros are secondary to the calorie band.
Watch / avoid
Nothing is forbidden by food group. Watch liquid calories, frequent takeout upsizing, and “healthy” extras (oils, nuts, cheese) that push you over the band. Skipping logging is the main failure mode.

High-protein
💪 Keep Muscle · Stay Full
Every meal is built around protein. It protects your muscle and keeps hunger away.
Protein-first macros to protect lean mass — useful with lifting or GLP-1 medications.
Drop fat, keep lean muscle
A high protein floor protects strength and body composition in a deficit.
Highest thermic effect
Your body burns more energy digesting complete proteins.
Built for active weeks
Fuels resistance training, running, and post-workout recovery.
🥩 Sirloin steak with roasted potatoes & greens🍗 Marinated chicken breast with quinoa & veggies🥣 High-protein skyr bowl with berries & seeds
Honest con: Expensive; meals get boring if cooking skills are low. Protein does not burn more fat than another equal-calorie diet — it helps muscle retention and satiety.
What to eat
Protein-forward plates: eggs, Greek yogurt, cottage cheese, chicken, turkey, fish, lean beef, plus fruit, potatoes, or rice to fill calories. Useful when lifting or on GLP-1 medications — hit the protein floor before fretting about carbs.
Watch / avoid
Ultra-low-protein “rabbit food” days and relying only on shakes without whole-food volume. If you have advanced kidney disease, this program is medically gated — talk to your doctor.

Mediterranean
🫒 Sunny Flavors · Heart-Friendly
Olive oil, fish, vegetables and unhurried meals. Easy to enjoy for years.
Olive-oil–forward, fish and plants — food pattern first, macros second.
Backed by decades of clinical trials
The most researched eating pattern for long-term cardiovascular health.
Vibrant, chef-worthy ingredients
Extra-virgin olive oil, fish, nuts, legumes, and fresh herbs.
A lifestyle, not a crash diet
Feels like coastal dining you can happily sustain for years.
🐟 Lemon-herb baked sea bream with olive oil🥗 Chickpea, feta & vine-tomato Mediterranean bowl🍆 Roasted vegetables with grilled halloumi & oregano
Honest con: Weakest calorie control — easy to over-eat “healthy” fats and nuts. Strong evidence for cardiometabolic patterns; no fat-burn edge vs equal calories.
What to eat
Fish (especially oily), vegetables, fruit, legumes, whole grains, nuts/seeds, olive oil, yogurt, and poultry in moderation. Lead with food groups — olive oil–dressed salads, chickpea bowls, grilled fish, lentil stew — not net carbs.
Watch / avoid
Processed packaged snacks, frequent sweets, and heavy red-meat weeks. Watch olive oil, nuts, and cheese portions — “healthy” fats still add calories fast.

Paleo
🌿 Real Food · Light Digestion
Simple whole foods: meat, fish, eggs, vegetables, fruit and nuts. No processed food.
Meat, fish, eggs, vegetables, fruit, and nuts — no grains, legumes, or dairy.

🥩 Grilled ribeye with baked sweet potato🐟 Roasted salmon with asparagus & toasted almonds🍳 Poached eggs over avocado and crisp greens
Honest con: Restrictive, with little extra benefit versus a balanced diet at the same calories. A whole-food filter can help some people eat less junk. It does not burn more fat.
What to eat
Meat, poultry, fish, eggs, vegetables, fruit, nuts, seeds, and olive oil or avocado. Build plates from protein + plants. Skip grains, legumes, dairy, and packaged sweets.
Watch / avoid
Grains, legumes, dairy, processed snacks, and sweets. Restaurant bread, beans, and cheese sauces are the usual slip-ups.

🥩 Pan-seared ribeye with butter and sea salt🍳 4-egg skillet omelet with crispy bacon🐟 Butter-basted salmon and wild shrimp
Honest con: Very low fibre, thin evidence, and hard to sustain socially. Not suitable in pregnancy or with kidney disease. Calories still decide fat loss.
What to eat
Beef, lamb, pork, poultry, fish, eggs, and optional dairy if you tolerate it. Keep the plate animal-only. Fat and protein cover calories; plants are off the list.
Watch / avoid
Vegetables, fruit, grains, legumes, nuts, plant oils, sweets, and processed snacks. If it grew in the ground, it is out on this pattern.

🍗 Herb turkey breast with brown rice & broccoli🐟 Lemon-baked trout with green beans & almonds🥣 Berry & flaxseed whole-grain oat bowl
Honest con: Not a weight-loss diet by design — calories still decide fat loss. Strong evidence for blood pressure. No fat-burn edge versus an equal-calorie plate.
What to eat
Vegetables, fruit, whole grains, beans, low-fat dairy, fish, poultry, and unsalted nuts. Cook with less salt. The pattern is food groups plus a sodium ceiling, not a carb ban.
Watch / avoid
Processed snacks, frequent sweets, heavy red-meat weeks, and high-sodium sauces or deli meats. Restaurant bread, soup, and condiments are where sodium usually overshoots.
