[Training] three full-body sessions a week through the whole cut

Training Cold Box ×3

Something I keep coming back to: three full-body sessions a week through the whole cut.

Hydration status and fasting state affect the lean mass estimate. Standardising both is the difference between a comparison and a coin toss.

Reduced appetite makes hitting a protein target a logistics problem rather than a motivation problem, which is why the practical advice here is about timing and food choice rather than willpower.

Strength retention is an imperfect but free longitudinal proxy: it is affected by neural factors and by being in a deficit, so it tracks tissue change loosely rather than exactly.

Corrections welcome, especially the pedantic ones. Pedantry is how this board earns its reputation.

Fat-free mass index is a ratio of fat-free mass to height squared. It moves when either term does, which makes it awkward to interpret during active weight change.

strength retention is a decent proxy and it is free

protein intake gets harder exactly when appetite drops

Left up. Same machine, stated conditions, honest about the error margin.

a single DEXA is a number, two is a comparison, three is a trend

Adding the free proxy — track a few lifts monthly. It costs nothing and it is longitudinal.

Some lean mass loss accompanies weight loss in any deficit. Resistance training and adequate protein intake are the two interventions with the best evidence for limiting the proportion.

Resistance training, and at what frequency?

replysharereportpermalink
u/lina_bruunOP7 points·4 days ago

How many weeks between the two scans?

Nothing here is a training or nutrition prescription. Targets and programmes are matters for somebody who knows your history and your training background.

the appetite effect makes eating enough protein a logistics problem

u/zeynep_villalobos5 points·4 days ago

Cosigning that protein gets harder precisely when appetite drops. That is the actual difficulty and it is logistical.

Disagree — slower loss does not automatically preserve lean mass. Protein and training do the work, not the rate on its own.

Careful, that is a nutrition prescription aimed at another member and this board does not do those.

lean mass loss during weight loss is expected, the question is how much

DEXA has a meaningful coefficient of variation, and it differs between machines and protocols. Comparing scans from different clinics adds a systematic offset that is invisible on the report.

resistance training first, cardio if there is time left

DEXA has a real error margin and people quote it to one decimal
