Weekly Fat-Loss Pace Planner: 0.5 to 1 Percent of Bodyweight

By Purpose with Presence Fitness · Updated November 3, 2026 · free, runs in your browser

Quick answer: A weekly loss near 0.7 percent of bodyweight kept lean mass in the one trial that compared rates head to head, while 1.4 percent did not; public-health guidance frames it as 1 to 2 pounds, or 0.5 to 1 kilogram, a week. Pick the pace, the planner gives the weeks and the weigh-in noise band.

How fast should you lose?

One randomised comparison in athletes set "a weekly body-weight (BW) loss of 0.7% slow reduction (SR) vs. 1.4% fast reduction (FR)" and found "LBM increased in SR by 2.1% ± 0.4% (p < .001), whereas it was unchanged in FR (-0.2% ± 0.7%)" (Garthe et al. 2011). Public-health pages give the same order of magnitude in absolute terms: "about 1 to 2 pounds a week" (CDC, Steps for Losing Weight) and "aim to lose 1 to 2lbs, or 0.5 to 1kg, a week" (NHS). The planner lets you choose 0.5, 0.7 or 1.0 percent of bodyweight a week and converts that to kilograms or pounds and to a number of weeks.

Why not plan with the 3,500-calorie rule?

The old rule says "a cumulative energy deficit of 3500 kcal is required per pound of body weight loss" (Hall 2008). The same paper's model "predicts that a larger cumulative energy deficit is required per unit weight loss for people with greater initial body fat", and a later test against seven supervised experiments found the rule "grossly overestimates actual weight loss" (Thomas et al. 2013). That is why this planner works in percent of bodyweight per week and asks you to steer by the trend, rather than promising a date from a calorie total. The calorie calculator gives the intake side; this page gives the pace.

What keeps the weight that comes off from being muscle?

Resistance training. An umbrella review found "Resistance training reduced lean mass loss during weight loss (1 SR-MA, MD: 0.8 [95%CI: 0.4-1.3] kg)" (Bellicha et al. 2021), and its companion position statement advises that "For preservation of lean mass during weight loss, an exercise training program based on resistance training at moderate-to-high intensity is advised" (Oppert et al. 2021). The planner's pace only holds if lifting continues through the deficit; the fitness program comparison lists the options by days and equipment.

Which program fits a cut?

Five short strength sessions a week keep every muscle under load on a cut without long sessions, which is what the 15-minute total-body program schedules.

15-Minute Series, Total Body Program (Antagonist Splits): 8 weeks, 5 strength sessions plus a cardio day, 15-minute sessions, full gym; $279.00 or 3 x $93.00, as shown on the product page on November 3, 2026.

Frequently asked questions

Why does the weekly amount shrink over time?+

Because the pace is a percentage of your current weight, so each week's target is a little smaller than the last. That matches how the research expressed the rates, 0.7 or 1.4 percent of bodyweight a week, and it keeps the loss from running ahead of a lighter body. The weeks-to-goal figure accounts for that shrinking step.

Is 1 percent a week safe?+

For most adults 1 percent of bodyweight falls near the top of the 1 to 2 pounds or 0.5 to 1 kilogram band that the CDC and NHS describe. The trial that compared rates found the faster rate, 1.4 percent, did not add lean mass while the slower one did. Heavier people reach 2 pounds a week at a lower percentage, so the planner flags that.

The scale went up this week. Is the plan failing?+

Not on one reading. Day-to-day body mass in stable adults varied with a standard deviation of 0.53 percent for a one-day interval and 0.69 percent over 7 days, driven by water and sodium. The planner shows that band for your weight. Judge the plan on a weekly average over two to three weeks before changing intake.

Do I still need to lift while losing weight?+

Yes, if you want the loss to be fat rather than muscle. The umbrella review quantified the effect of resistance training as 0.8 kilograms less lean mass lost, and the position statement that followed advises resistance training at moderate to high intensity for lean-mass preservation. Two sessions a week meets the federal guideline floor.

Can I use this for a very low calorie diet?+

No. Very-low-calorie diets, near 800 calories a day, are described by MedlinePlus as medically supervised and only for adults with obesity who need to lose weight for health reasons, for a limited time. This planner assumes a moderate deficit from a normal diet. If your plan needs that kind of intake, speak to a clinician.
