Your numbers are a starting point. Your habits are the work.
You’ll see estimated calories, macros, and hand portions, then bring the conversation back to the real question: which habit is hardest for me to repeat this week?
Step 1 · Personal profile
Begin with the person, not the plan.

Sam’s practical starting range
This estimate starts with your body, layers in your movement, and adjusts for your goal. The range is intentional: you are looking for a useful beginning, not a perfect number.
Daily calorie range
1,584–1,822
Middle target: 1,703 calories/day.
Protein anchor
145 g
Protein is set first because it makes the day easier to structure.
Maintenance estimate
2,003
Estimated BMR: 1,441 calories before activity.

Step 4 · Hand portions
Numbers translated into something you can actually use at a meal.
This is the bridge from the estimate to your plate. You can use these hand portions to turn the numbers into ordinary meal-building habits.
Palms of protein
6
2/meal
1 palm ≈ 3 oz cooked meat or tofu, 1 cup Greek yogurt or cottage cheese, 1 scoop protein powder, or 2 whole eggs.
Fists of vegetables
5
1.5/meal
1 fist ≈ 1 cup non-starchy vegetables such as spinach, carrots, cauliflower, or peppers.
Cupped hands of carbs
6
2/meal
1 cupped hand ≈ ½ cup cooked grains or legumes, 1 medium fruit, or 1 medium potato or yam.
Thumbs of fat
5.5
2/meal
1 thumb ≈ 1 tablespoon oils, nuts, seeds, nut butters, cheese, or dark chocolate.
Step 5 · The reveal
Personalization changes the starting line. It does not remove the chain.
A calculator can help you feel seen, especially if you have wondered whether your body needs a more personal starting point. After the estimate is made, the work returns to the links that shape your everyday behavior: the cue, the environment, the emotional state, the choice, the reward, and the repetition.
Step 6 · Habit reflection
Where does it break down for you?
This is the behavior-design turn. Instead of getting stuck on the estimate, you can get curious about the link that breaks most often and choose one experiment small enough to repeat.
A helpful next step invites noticing. It does not tell you that you “just need discipline.”
This week’s simplest experiment
Is the food decision happening when energy is lowest?
Choose tomorrow’s first supportive meal tonight. Do not plan the whole week; plan the next repeatable choice.
Ready · Willing · Able check
Notice where resistance is actually coming from.
A lower score is information, not failure. Rate the selected roadblock across all three questions so you can see whether the next step needs better conditions, more willingness, or more practical skill and support.
Ready
Are you mentally and logistically prepared to make this possible?
0 means the timing and circumstances in my life are working against this right now.
10 means the timing, environment, and support in my life are lined up.
Willing
Am I open to doing this, even if it feels uncertain or uncomfortable?
0 means the part of me that wants to stay the same feels stronger than the part that wants to change.
10 means I am open to this, even if it feels uncertain.
Able
Can I realistically do this with my current life?
0 means I am not sure how to do this in practice.
10 means I know exactly what this looks like and feel confident I can do it.
Closing reflection
Numbers inform. Habits transform.
Numbers can give you a starting point. They can help you notice what your body may need, what direction you are moving, and where a small adjustment might support your goals. But numbers do not carry us to our destination on their own. The path is built through the habits we are willing and able to repeat.
In the Chain of Habits™ framework, every small action is a link. When a link is practiced steadily, even imperfectly, it starts to become part of how you move through your day. That is why a habit done even at 50% consistency produces measurable, real progress — and 80 percent is where meaningful, lasting change lives.
Go small enough
You might ask, “What is one action that feels realistic enough to practice this week?” Small changes keep you going when life is full and busy, emotions are heavy or motivation is not high.
Stay steady enough
One or two habits are enough to begin. When they start to run with less effort, you can consider adding another link instead of asking yourself to change everything at once.
The invitation is not to be perfect. It is to choose the next honest link, practice it steadily, and let your habits become the quiet structure that carries you toward the life and health you are building.
