Good value given

Eric Helms says fat loss comes from an energy deficit, and lifting is the best tool to make sure the loss comes from fat.
He suggests mostly single ingredient foods for fullness, with room for treats so the diet doesn't feel like a ban.
Coach Cliff Wilson says stubborn fat does come off eventually if you keep going, and building muscle in an area helps it look leaner.
A habits researcher in the video suggests 'designing for laziness', like keeping snacks out of sight, so you rely less on willpower.
Layne Norton says no one diet wins when calories are equal, and people who keep weight off tend to self-monitor and exercise.

What's the smartest way to get lean?

The experts agree it comes down to a few basics in order of importance: eat a bit less than you burn, keep lifting weights so you hold on to muscle, keep the deficit moderate, eat enough protein, and use cardio as a side tool. After that, the people who keep weight off tend to build habits, weigh themselves regularly, exercise and favor long term goals over short term cravings. Most fat burner supplements, they say, aren't worth it.
