We can see in Matthew 4:2, that the enemy did not tempt Jesus, about eating, before Jesus became hungry. After many days of fasting, Jesus became hungry. Then the enemy tempted him based on the hunger Jesus had.
The enemy tempts people, when they feel weaker, in their lowest point, because it is easier for people to fall into sin, when they feel weak, than when they feel strong, in any particular area. So the weakness of Christians, could be targeted by the enemy.
But glory and thanks be to our Lord Jesus Christ, that he has not left us alone, to deal with our own weaknesses, but always provides us with power, when we are weak.
His grace is sufficient for us, in our weakness – 2 Corinthians 12:9
The power of the Holy Spirit in us, makes us able, to stand against the temptations from the enemy, and to make us victors, instead of victims. God turns our weakness into victory, because, all things work for good, for those who love the Lord.
