Fat loss without guessing

A calorie range, a protein target and a week you can repeat will do more than another cleanse. A practical starting point for fat loss that respects your life.

Fat loss is not a mystery, but it is easy to make complicated. Most people do not need a new superfood or a stricter list of forbidden meals. They need an honest starting point, a target they can live with, and enough strength work to keep the muscle they already have.

This is general education, not medical advice. If you have a health condition, are pregnant or are working with a clinician, follow their guidance first.

01

Start with a week of honest data

Before changing anything, write down what you actually eat for a week. Not what you think you should eat. The point is not to judge the week; it is to find the gap between the plan in your head and the week on your calendar.

Most people find one or two repeatable patterns: a late-night snack, a liquid lunch, a weekend that undoes five careful weekdays. You do not need to fix all of it. You need to know where the leverage is.

02

Set a calorie range, not a rule

A single calorie number looks precise and rarely survives real life. A range gives you room to eat a little more on a hard training day and a little less on a quiet one. The average is what matters.

Use an estimate as a starting point, then adjust based on what your body does over several weeks. The calorie and protein tool on this site uses Mifflin-St Jeor and standard activity multipliers; it is an estimate, not a measurement.

  • Lose: roughly 15% below estimated maintenance.
  • Maintain: estimated maintenance.
  • Gain: roughly 10% above estimated maintenance.
03

Protein is the lever

Protein helps you keep muscle while you are in a deficit and tends to make meals more satisfying. A common target is roughly 0.7 to 1 gram per pound of body weight per day, spread across meals.

That is a range, not a rule. People with larger bodies, medical conditions or kidney concerns should get individual guidance from a qualified professional.

04

Lift so you keep muscle

A calorie deficit without strength work can leave you smaller and weaker. Strength training gives your body a reason to hold onto muscle while fat loss is happening. At RTS, muscle building and fat loss are core specialties, and the small-group format keeps the work scaled to the person.

You do not need a perfect program. You need consistent, progressive strength work and enough recovery to show up for the next session.

05

Make the habit smaller than your motivation

The plan that works on a motivated Sunday often dies on a tired Wednesday. Make the habit small enough to survive the worst day of your week: one planned breakfast, one walk after lunch, one strength session you do not skip.

Ray's coaching focus is fixing daily habits, not chasing a heroic month. That is the right order. The habits are what make the result stay.

06

When to ask for help

If you have been tracking for a few weeks and nothing is changing, or if the plan is making you miserable, get a second set of eyes. A coach can help you adjust the target, protect your training and stop you from responding to a bad week by cutting everything in half.
