Why most diets fail
Most people don’t stick to rigid rules. The winning formula is simple: eat mostly whole foods, hit your protein, create a small calorie deficit, and stay consistent. That’s it.
Consistency beats perfection. A plan you can repeat for months will always outperform a perfect plan you quit next week.

21 science-backed tips
1) Eat 0.7–1.0 g protein per lb
Protein helps you stay full and keeps muscle while losing fat. Think chicken, Greek yogurt, eggs, tofu, beans.
2) Create a 300–500 kcal deficit
A small, steady deficit burns fat without constant hunger. Use the calculator below.
3) Front-load protein at breakfast
Eggs + oats or Greek yogurt beat donuts for hunger control all day.
4) Fiber at every meal
Veggies, beans, fruit, potatoes with skin—fiber slows digestion.
5) Drink water, then coffee or tea
Hydration + light caffeine curb appetite without calories.
6) 80/20 rule
80% whole foods, 20% flexible treats to avoid binge-restrict cycles.
7) Weigh 2–3×/week
Look at the weekly average, not day-to-day swings.
8) 7–9k daily steps
Walking is underrated fat-loss “cardio” that doesn’t crush recovery.
9) Lift 2–4×/week
Strength training preserves muscle, which keeps metabolism higher.
10) Sleep 7–8 hours
Short sleep increases hunger hormones and snacking.
11) High-volume swaps
Popcorn over chips, berries over candy, potatoes over fries.
12) Liquid calories are sneaky
Soda, fancy coffees, juices—switch to zero-sugar options.
13) Plan your environment
Keep protein and fruit visible. Hide trigger snacks.
14) Eat slowly
Give fullness signals time—15–20 minutes per meal.
15) Plate method
½ veggies, ¼ protein, ¼ smart carbs, 1–2 tsp healthy fat.
16) Weekend guardrails
Keep breakfast routine; pre-log dinners; limit “all-or-nothing”.
17) Protein snacks
Jerky, cottage cheese, protein shakes, edamame.
18) Mindful eating
No screens for the first 10 minutes of meals.
19) Smart eating out
Grilled > fried; veggies sides; dressings on the side.
20) Track 2 things
Protein grams and steps. Keep it simple.
21) Review weekly
