All Roads Lead To Strength Training

Stephen Strong, M.D. · September 2026

People get stuck spinning their wheels for a few predictable reasons. They're trying desperately to lose weight quickly. They're trying to exercise their way out of a problem. They don't understand how vital building and maintaining muscle mass is. Or they're focused on belly flab and doing everything they can think of to get rid of that one thing.

Underneath all of it is the same mistake, and it's worth understanding in detail — because it's the mistake that compounds.

The cycle

Our bodies don't respond well to starvation and calorie deficits.

Here's what I watch happen to people. They go through a deficit phase. They lose weight. But without strength training, a meaningful share of what they lose isn't fat — it's lean mass. Somewhere in the range of a quarter of the total, sometimes more if the deficit is aggressive or they're already fairly lean.

Then the weight comes back, as it almost always does. But it doesn't come back in the same proportion. The regain skews harder toward fat than the loss did.

So picture it across one cycle. Ten pounds off, maybe seven of it fat and three of it lean. Ten pounds back on, maybe eight of it fat and two of it lean. The scale is exactly where it started. The body is not. It is a little softer, a little weaker, a little less metabolically capable than it was a year ago.

Now run that four or five times over fifteen years.

What you're left with is a body that's increasingly sarcopenic and carrying a lot of fat, at a weight that may look unremarkable on a chart. And it's painful to watch, because it becomes progressively harder to fix. The person starts to feel desperate to lose the fat, so they crash diet again to try to correct it — which is the exact thing that created the problem.

This is why I don't think "what diet should I do" is usually the right question. You can be perfectly compliant with a diet and still end up worse off than when you started.

Breaking it

I'm becoming increasingly convinced that the only way to truly break the cycle is to focus on strength training. Not as an add-on to a diet. As the thing itself, with the eating built around it.

When you train, you change where the fuel goes. You give your body a reason to preserve and build skeletal muscle instead of treating it as a cost to be cut. That lowers your body fat percentage, improves insulin sensitivity, and — I'll say the unserious part out loud, because it matters to people — it makes you look and feel better.

For most people, the first thing that will help them is to start strength training. Not to start it eventually, after they've lost some weight first. To start it now, at whatever weight they currently are.

People are sometimes afraid they'll get too bulky. I'd gently suggest that if you're worried about that, the odds are you've never been in a deficit and strength training at the same time — the two together are not a recipe for accidental bulk. It's hard to build muscle. It takes a long time and a lot of deliberate effort, which is the whole subject of the next piece.

The real objection I hear more often is a quieter one: I'll start lifting once I lose some of this. I understand the instinct. But that's backwards, and it's the sequencing that keeps people stuck for decades.
